How to choose best long range walkie talkie?

Before buying a long-range walkie talkie for your personal or business needs, many customers look for a walkie talkie buying guide. As walkie talkie dealers we have been thinking about sharing this guide with consumers. To inform our clients as to their need to buy the two-way radios. Walkie talkies are a two-way communication mode which is efficient and instant. They particularly come into use when a group of people or two individuals want to stay in contact continuously. You'll be surprised to learn that walkie talkies, once used only by military officials, are now also used as a baby monitor. Then in order to buy walkie talkie, you need to go through a list of some tips to select the right walkie talkie for your needs.

Frequency:

Use FM radio frequency and have up to 99 channels to deal with. They are less costly than GMRS systems. They are user friendly for everyone. However, when compared with GMRS they have limited production and range. They usually have coverage of up to 1 Mile. For commercial radios, the UHF radio frequency ranges from 400 – 512 MHz. Around this frequency runs two-way radios, GPS, Bluetooth, cordless phones, and WiFi.

UHF Radios:

UHF radios have a lower range, with more channels available. Thus it becomes an appropriate option for populated areas. Because the distant radios are less likely to interfere with your channel, with its lower range. UHF's shorter-range helps it to enter more spaces within a house. Thereby featuring fewer obstacles which completely block its frequency. Another advantage of a UHF radio is that the antenna on the long-range walkie talkie is shorter because of the shorter wavelength. And making it more job-friendly to bring around.

Very-High Frequency Two-Way Radios:

They operate between136-174 MHz. The advantage of VHF walkie-talkies is that they cover more distance with less power because VHF waves are longer and stay closer to the ground. VHF radios are used primarily for aviation and marine communications and are perfect for ground maintenance workers, use in open fields, golf courses, and outdoor defence. However, VHF signals do not penetrate very far into metal and concrete structures, so VHF radios might not be accurate at very built-up locations. There are some main features with this that you need to study when you are buying the best industrial or commercial walkies. Here's a list of key features you need to compare when you buy the best long-range walkie-talkies.

Walkie Talkie Channels:

Two-way radios can have multiple channels that suit the user's needs. If your requirement requires that a group remain linked at the same time. In that case, the target will be solved by a 1 channel radio. But when your work involves teamwork among different groups. And you don't want to get a group upset by the other group's contact. Then for the best walkie talkie experience, you'll need multiple channel radio. In addition, a manager or the person in charge will easily communicate through a radio that scans through several groups. So as to link by tuning in to the desired channel to any party. For example, if you're in a building company. You can then assign Channel A to Internal Office, Channel B to Contractors, Channel C to the Financial Department and so on.

Autopilots The first self-steering equipment was introduced in the 1920's to control model private yachts but it was not till 1948 that the principle was related to complete range yachts. Standing at the helm for lengthy durations, keeping track of instruments as well as maintaining an excellent watch out can be very tedious. An autopilot alleviates the helmsman from steering the proper training course leaving him complimentary to maintain a correct watch. The autopilot can be set to either steer a compass program or a training course about the wind. A fluxgate compass or electronic wind sign feeds information to a microprocessor which after that makes the essential rudder activities to return the vessel to it's called for training course. The mechanical power is applied to the rudder by either electric direct activators, hydraulic pumps or rotary drives. GPS/Chart plotters can be used to input navigational guidelines to the auto-pilot.

Battery Chargers will keep batteries fully billed therefore expanding their functioning life.

Chart Plotters Typically a chart plotter contains an antenna, placed high on the watercraft, to track GPS signals and a display screen system sited either at the at the navigating station or the helm of the vessel. The vessels position is sent out from the antenna to the screen device which consequently reveals it graphically on the graph. The Chart itself will look comparable to it's paper equivalent as well as reveal depth, land mass, navigational aids such as bouys and prospective risks in the form of accidents and obstructions. The customer can include method indicate the chart as well as focus and out of the display screen. Graph plotters can be connected to drive an autopilot and/or send GPS information to a fish finder or radar. They can additionally user interface with a laptop allowing intricate passage preparing to be done away from the boat and after that became part of the graph plotter after coming to the watercraft.

Magnetic Transmitting Compasses function like traditional compasses making use of magnets to determine the vessels alignment to the planet's electromagnetic field they after that transfer the boats heading to an electronic screen. They make guiding much easier than with conventional compasses due to the fact that they show steadier headings and also do not struggle with the "lag" that occurs when making a turn. They can interface with chart plotters, autopilots and radar. Fluxgate Compasses include 2 items of easily filled magnetic material with coils wound rounded them in opposing instructions. AC current is gone through the coils as well as the product is filled in one instructions and then the various other. The planet's magnetic field affects a little the time at which saturation happens, earlier in one coil and also later in the various other. The distinction is after that determined giving an outcome symmetrical to the planet's electromagnetic field. They are exact to 0.1 of a degree. Their result can be displayed digitally to the helmsman or they can user interface with auto-pilots, chart plotters as well as radar.

14 Common Misconceptions About Fish Finder Gps Combo

Marine Electronics

Auto-pilots The first self-steering equipment was introduced in the 1920's to control model luxury yachts but it was not till 1948 that the concept was put on complete scale luxury yachts. Standing at the helm for lengthy durations, keeping an eye on tools and also maintaining an excellent look out can be really tiring. An autopilot eliminates the helmsman from guiding the proper training course leaving him free to preserve an appropriate watch. The auto-pilot can be set to either steer a compass training course or a course about the wind. A fluxgate compass or electronic wind indicator feeds info to a microprocessor which then makes the needed tail activities to return the vessel to it's needed program. The mechanical power is applied to the rudder by either electrical direct activators, hydraulic pumps or rotary drives. GPS/Chart plotters can be used to input navigational guidelines to the autopilot.

Battery Chargers will keep batteries fully billed consequently prolonging their working life.

Chart Plotters Typically a graph plotter contains an antenna, placed high on the watercraft, to track GPS signals as well as a screen device sited either at the at the navigating station or the helm of the vessel. The vessels position is sent out from the antenna to the display device which consequently reveals it graphically on the chart. The Chart itself will certainly look similar to it's paper comparable as well as show deepness, land mass, navigational aids such as bouys as well as potential threats in the form of wreckages as well as blockages. The user can add method indicate the chart and also focus and out of the display. Chart plotters can be linked to drive an auto-pilot and/or send GPS information to a fish finder or radar. They can additionally user interface with a laptop computer making it possible for complicated flow planning to be done far from the boat and after that entered into the graph plotter after getting to the boat.

Magnetic Transmitting Compasses function like standard compasses utilizing magnets to determine the vessels alignment to the planet's electromagnetic field rainbow trout fishing tips they after that send the watercrafts heading to a digital display screen. They make guiding less complicated than with standard compasses because they present steadier headings as well as do not struggle with the "lag" that takes place when making a turn. They can user interface with chart plotters, autopilots and radar. Fluxgate Compasses include 2 items of readily filled magnetic material with coils wound round them in opposing instructions. AC current is gone through the coils as well as the product is filled in one direction and afterwards the other. The earth's magnetic field affects a little the time at which saturation happens, earlier in one coil and later in the various other. The distinction is after that calculated giving an output proportional to the earth's magnetic field. They are precise to 0.1 of a degree. Their output can be shown electronically to the helmsman or they can user interface with auto-pilots, graph plotters and also radar.

Our Top 6 things you absolutely MUST bring with you 4WDing!

New Post has been published on https://www.4wdsupacentre.com.au/news/our-top-6-things-you-absolutely-must-bring-with-you-4wding/

Our Top 6 things you absolutely MUST bring with you 4WDing!

If you are getting ready for a trip offroad, the list of gear you could, should and eventually will bring with you, seems to go on forever, the tedium of organizing all of your gear makes it just a little bit easier to put off trips away with the family and friends.

But procrastinate no longer, we are going to run down the top 6 things you absolutely MUST bring with you when heading on trips away, many of these things you should keep in the car indefinitely. 1.Navigation Equipment.

When travelling far into the unknown, it is easy to forget that 4g reception hardly ever works when you need it the most, on top of that, your smartphones map application will typically be unable to provide clear and detailed mapping of the area you are driving in. This is why any adventurer worth their weight in salt, knows that you need a DEDICATED GPS navigation system like the VMS Touring 700HDX with both detailed topographic maps and on road turn by turn navigations, with the ability to leave a breadcrumb trail to backtrack if required, you’ll wonder how you ever did without one of these awesome devices!

  2.Clear Communications As with navigation requirements, the necessity to be “off grid” and “self sufficient” are important when it comes to communications, mobile reception towers are few and far between, and in our opinion GOOD RIDDANCE! However, it is still extremely important to stay in contact with any other 4WDs on the tracks, as well as being able to call for help in emergency situations.

This is where UHF comes in, UHF is somewhat restricted in overall transmission power being legislatively restricted to only 5W compared to the 25W found in VHF marine radio or up around 100W found in some AM radio transmitters.

Due to its relatively low power, this means it can be used as an effective unlicensed CB radio, and when fitted with the right dBi antenna still is able to reach out beyond 20km (or much, more when using the duplex repeater function and a repeater station). If you are looking for a powerful 5W UHF with a 6.5dBi antenna all in a no soldering installation then the Oricom UHF380PK is perfect for you!

3.Spare Fluids

Even if your vehicle is newer, particularly on longer trips, it’s a really good idea to equip your 4WD with spare liquids such as;

engine oil the same rating as the oil in your engine already, fresh water approximately 20L can be used to add to radiator or as emergency drinking water or even for washing hands, fuel  for just in case you misjudge distances, transmission fluid, brake oil make sure you use the right type recommended for your vehicle and coolant concentrate, no point carrying heavy premixed coolant if you have a 20L jerry of fresh water too!

  4.Air!

This sounds silly but being able to measure and adjust your tyre pressures offroad will be one of the most critical aspects of how much grip and how much performance your 4WD has offroad. We recommend at least carrying a Thumper MKII Air Compressor and a Kwiky Tyre Deflator. You can drop your tyre pressures in seconds and re-inflate in just a minute or two per tyre.

There is no substitute to having a reliable air compressor, and purpose made tyre deflation tool in your arsenal!

  5.Recovery Kit!

This one goes without saying, however there are a bunch of different ways that people use to get their 4WD free when the line they chose on the tracks just simply didn’t work out the way that was planned.

If you are lucky enough to have a bull bar fitted to the front of your 4WD then fitting a Domin8r X 12,000LB winch to the front will surely get you out of just about anything, however a winch on its own is next to useless, you will have to hook it up using all the right rated straps, and rated shackles and if you were wanting even more power, using something along the lines of a rated Snatch block pulley can give you up to double the pulling power!

If you find yourself driving on soft surfaces like sand a lot then something like a snatch strap might be just the ticket, it is a clever way to bungee your 4WD out of trouble using stored kinetic energy from another 4WD!

There are a handful of different recovery kits available in the 4WD Supacentre range, but the most comprehensive is the Hercules Complete Recovery Kit, including a shovel gloves and even a Kwiky Tyre Deflator along with all the other bits and pieces required for snatch strap and winch recoveries.

  6.Recovery Safety

This one is more critical than ever no matter which recovery method you employ, there is inherent risks involved with tons of force and load bearing straps shackles and hooks, so to increase your safety, you must always think of safety above everything, All winch recovery kits in the range include a winch dampener to stop potential projectiles from hurting spectators or damaging vehicles.

On top of the winch dampener, you should also consider the anchor point you are fastening your winch or snatch strap too. Whilst you may be tempted to hook onto your tow ball, or your vehicles integrated tie down loops, you should seriously consider getting a set of rated tie down points fitted to your vehicle!

Know More on Anchor Chain Suppliers to Meet Your Ship Requirements

Marine Equipment is important to navigate the ship towards its target point from its set point. Moreover, you won’t be able to control the ship without using them accordingly. Effective marine equipment with excellent quality help to overcome all the obstructions during the ship movement. Furthermore, those tools help to reach the destination point very fast effortlessly. Not only that but also it helps to identify the issues if any occurs during the sailing. Here, we are going to talk about the importance of the Ship navigation tools, especially we are focusing on the anchor chain. So, you need to buy the marine tools from Marine Equipment Manufacturers based on the ship requirements and enjoy the voyage without any troublesome.

Essential Marine Equipment’s Used for Ship Navigation Techniques:

Some of the vital tools that are very essential to navigate the ship are discussed below. As a Ship Operator, you can buy them from experienced Marine Equipment Manufacturers and use them accordingly.

Gyro Compass

Gyro Compass is an important component for finding the right direction. It is very essential for locating the correct North Position as it is not affected by the external magnetic field. Thus, the repeater system also provides a stable direction source. As a result, it plays as an effective steering platform used for emergency steering.

Radar

The seagoing vessels need to detect the targets such as the distance between the land and ship. Moreover, it also helps to identify the obstructions like floating objects, other vessels, ricks and icebergs towards the ongoing path. Thus, this rotating antenna discovers the surrounding area of the ship and avoid the collision during the ship movement easily.

Auto Pilot

Autopilot faculty is considered to be one of the efficient bridge navigation tools in controlling the ship. It assists the human operator to control the entire steering operation in autopilot mode. Not only that but also it allows the drivers to concentrate on the broad aspect of the procedure without any conflicts from the remote location.

ARPA

Automatic Radar Plotting Aid (ARPA) displays the current locations of the ship and its nearby vessels positions. Moreover, it also helps to identify the region on which the ship is passing and takes necessary steps for the vessel to avoid any kind of collision. This bridge navigation equipment constantly monitors the nearest floating objects, boats, ships, etc. as well as their speeds. This tool also helps to upgrade the parameters with each turn of the antenna by calculating their nearest approach to ownership.

Speed and Distance Log Service

This superior service is used to measure the speed of the ship and the distance covered by the ship from a set point. Thus, the ship operator and the port authority can easily adjust the ETA of the ship and calculate the accurate distance traveled by the hip.

 GPS Receiver

Global Positioning system receiver is one of the very crucial marine equipment use to show the ship's current location with the help of the geostationary satellite. It is one of the easiest ways to measure the distance between speed, distance, etc. In addition, it also helps to assume the time to reach the destination point by using the Two Mark positions technique.

Anchor Chain

The anchor chain is the most important part of the entire anchoring system. It is used to handle anchor of the ship very fast by managing it properly. Thus, the ship can easily float if water and there is not a problem that the ship operator can encounter during the sailing program.

Echo Sounder

The echo sounder is one of the oldest equipment used in Marine management process in the newest form. It is one of the useful Marine tools to know the death of the water below the ship’s bottom by using the sound waves. It works on the principle of sound waves transmissions and audio pulses which comes contact to the reflecting layer automatically. Then, it bounces back to the source as echo form.

Radar Angle Indicator

This effective tool shows the navigation equipment console clearly and the navigation officer can control the rudder of the ship. Moreover, its angle indicator helps to manage the turn rate and the officer can get notification about the rudder from the engine control room without facing any issue.

Auto Identification System

AIS is one of the necessary navigation systems that helps to identify the pinpoint location and other ships navigational status. The unique feature that you can see in this tool is AIS uses very effective VHF radio channels. So, the ships can transmit important data and pass through this channel to other ships as well as their own passengers. So, it fulfills all the responsibilities to transfer the data in case of an emergency and avoid the possible conflicts.

Voyage Data Recorder

As a ship navigation officer, you must install the Voyage Data Recorder (VDR) from the Marine Equipment Manufacturers. It is an important tool to record all vessel-related vital information and it also contains a voice recording system that lasts at least a recent 12 hours. So, it is very beneficial marine equipment to investigate any accident events.

Various Type of Anchor Chains available for Vessels:

Before knowing the types of Anchor chains, you need to consider the Anchor’s grade for vessels. If you are using a windlass, then select the chain as per the manufacturer’s specifications. Higher grade of the chain gives high holding power and the chain is also heavier than other normal Anchor chains. Besides this, chain material plays a crucial role in its longevity owner. Stainless steel chain has a lower breaking point but looks better due to less prone to rusting. However, you must see the best one as per your anchor type and based on its specifications.

Gr 300 Proof Coil

This general purpose a chain is constructed from low carbon steel and is hallmarked with the manufacturer's symbol. However, this proof coil chain doesn’t have any uniform pitch and won’t be able to work with windlasses.

BBB Anchor

This windlass chain has a uniform pitch with a short link and can perform well with gypsies. This hallmarked  BBB anchor product is also constructed with low carbon steel but is standard for the windlass. Hence, this anchor chain is effective if and only it is replaced with a G4 chain and you can identify it with 3B mark.

Gr 40 Hight Test and Gr 43 Hight Test

This is almost identical for Gr 43 chain and it has also smaller chain links. It is also ISO standards and it has the capability of taking a twice load of BBB chain. Moreover, it allows a small chain size and you can easily handle it without facing a conflict during the ship anchoring. The G 43 is made of the high carbon steel and is most similar to the G 40. But, the product has more strength than the G 40 tool. Marine Equipment Manufacturers gives the mark that is IOS o standards and labeled with 4, 40, 43, etc.

Gr 70 Transport

This anchor chain is commonly known as the transport chain as it has a very high strength to the ratio. Even, it has about 25% more strength than other chains. This product is hallmarked with the manufacturer's symbol on it's every foot and grade markings are available like 7,70,700, etc.

Importance of Anchor Chain in Ship Navigation Program:

There are lots of importance you can see if you select the perfect Anchor chain and make it very useful. Moreover, its incredible performance and outstanding facilities help the anchor to handle very smoothly without any troublesome. Here, we are going to discuss the major roles of Anchor chain in the Ship navigation process.

Anchor chain helps to set the anchor very fast and makes it more reliable as it can create a download pull on the anchor handle.

Anchor chain helps to set the rode horizontally instead of pulling the anchor handle upward.

Moreover, the anchor chain protects the nylon line from the debris and also sharp objects that may be responsible for losing the anchor.

Another benefit you can avail if you buy the anchor chain from experienced Anchor Chain Suppliers in UAE. It can transfer the energy to the extreme end of the anchor handle and also a downward motion.

It uses the breakaway release method for minimizing the     chances of losing the anchor. Moreover, it helps to utilize the anchor by protecting the anchor from the objects, debris stuck under it. Thus, the ship operator can enjoy a trouble-free ship journey.

In this article, we have defined the essential marine tools that play an effective role in the ship management system. Moreover, the above tools guide the ship operator a lot at the time sailing. Besides this, we have also discussed the importance of that particular equipment with their functionalities. We have also try to highlight the significant roles of Anchor Chain in the Ship.

30 Types of Navigation Equipment and Resources Used Onboard Modern Ships

Gone are the days when a ship navigation officer had to take help of unconventional ways to plan and navigate a voyage at sea. Today, a ship officer has myriad of marine navigation equipment which makes his life a lot simpler, thanks to the advancement in technology.  Moreover, present-day seafarers are trained so as to know the functioning and operation of all modern day navigational equipment that has made the journey at sea smoother and safer.

With modern day facilities and automation, a ship today has several advanced navigation equipment systems which give accurate data for the voyage.

Image for Representation Purpose only; Credits: wikimedia.org

Herein, we have enlisted 30 types of navigational equipment, both old and new, which are present on all merchant ships.

1.   Gyro Compass

It is used for finding the right direction. Unlike magnetic compass, gyro compass is not hampered by an external magnetic field.  It is used to find the correct North Position, which is also the earth’s rotational axis to provide a stable directional source. Its repeater system must be present in the steering platform for emergency steering.

2.   Radar

The seagoing vessels depend on S-band and X-band frequency radar system for navigation as it can detect targets and display the information on the screen such as the distance of the ship from land, any floating objects (an island, rocks, iceberg etc.), other vessels, and obstacles to avoid a collision. It is a rotating antenna which discovers the surrounding area of the ship.

3.   Magnetic Compass

The magnetic compass work in conjunction with the magnetic field of the earth and is the essential means of the direction indicating device. It is used to get a planned course for the voyage. This ship navigation equipment is usually fitted at the centre line of the ship on the monkey island.  A transmitting magnetic type compass is fitted so that the output can be displayed in the bridge panel.

4.   Auto Pilot

The ship bridge layout is filled with equipment and tools used for navigation. The autopilot is considered to be one of the most effective bridge navigational equipment as it assists the human operator in controlling the ship by keeping the steering in autopilot, which allows them to concentrate on broad aspects of the operation.

It is a combination of hydraulic, mechanical, and electrical system and is used to control the ship’s steering system from a remote location (Navigation bridge).

5.   ARPA

Automatic Radar Plotting Aid displays the position of a ship and other vessels nearby. The radar displays the position of the ships in the vicinity and selects the course for the vessel by avoiding any kind of collision.

This bridge navigational equipment constantly monitors the ship’s surrounding and automatically acquires the number of targets, in this case; ships, boats, stationary or floating objects etc., and plot their speeds and courses respectively. It also presents them as vectors on the display screen and constantly update the parameters with each turn of the antenna by calculating their nearest points of approach to own ship and also the time before this will occur.

6.   Automatic Tracking Aid

Just like ARPA, automatic tracking aid displays the information on tracked targets in graphic and numeric to generate a planned layout for a safer and collision-free course.

Usually, A large size target measuring 800 m or more in the circumference is considered as a landmass and not tracked. Echoes less than 800 m are deemed as targets to be tracked.

7.   Speed & Distance Log Device

This bridge equipment on a ship is used to measure the speed and the distance travelled by a ship from a set point. By calculating the same, ETA of the ship is adjusted or given to the port authority and agent.

8.   Echo Sounder

There are many modern ship navigation tools present on ship and echo sounder is one of the instruments which has been in the play from almost 100 years now. It is used to measure the depth of the water below the ship’s bottom using sound waves which work on the principle of transmission of sound waves and an audio pulse which will bounce off a reflecting layer, returning as an echo to the source.

9.   Electronic Chart Display Information System

ECDIS is a development in the navigational chart system used in naval vessels and ships. With the use of the electronic navigation equipment, it has become easier for a ship’s navigating crew to pinpoint locations, and attaining directions are easier than before.

10. Automatic Identification system

AIS is also among the types of a navigation system which helps to pinpoint the location and other navigational statistics of ships. AIS uses VHF radio channels as transmitters and receivers to send and receive messages between ships which endeavours to fulfil a lot of responsibilities.

As per the regulation enforced by The International Maritime Organisation (IMO), all passengers’ vessels and commercial ships over 299 Gross Tonnage (GT)  sailing in the international to carry a Class A AIS transponder.

11. Long Range Tracking and Identification (LRIT) System

LRIT is an international tracking and identification system incorporated by the IMO under its SOLAS convention to ensure a thorough tracking system for ships of 300 gross tons and above which are on international voyages across the world. This maritime equipment is fitted to improve the maritime domain awareness.

Read more about LRIT here.

12. Rudder Angle Indicator

Rudder angle indicator, as the name indicates, provides the angle of the rudder. The display is provided on the navigation bridge equipment console so that the ship navigation officer can control the rate of turn and rudder angle of the ship. The indication is also provided in the bridge wing and engine control room.

13. Voyage Data Recorder

A VDR or voyage data recorder is a crucial instrument among the ship navigation equipment list which is installed on a ship to continuously record vital information related to the operation of a vessel. It contains a voice recording system for a period of at least the last 12 hours. This recording is recovered and made use of for investigation in events of accidents. The importance of VDR is similar to a “black box” installed on an airplane.

Read more about VDR here.

14. Rate of turn indicator

This navigational tool indicates how fast the ship is turning at a steady rate (useful during pilotage and manoeuvring), normally shown as a number of degrees turned. The rate a ship is turning is measured in degrees per minute. This essential tool assists a coxswain in steering a course safely.

15. GPS Receiver

A Global Positioning System (GPS) receiver is a display system used to show the ship’s location with the help of Global positioning satellite in the earth’s orbit.

With the record of the ship’s positions, the speed, course, and the time is taken to cover the distance between “two marked positions” can be calculated.

16. Sound Reception System

This acoustic system is required for a ship with a fully enclosed type bridge. It enables the navigating officer inside the cabin to listen to the sound signals (such as fog or ship’s horn) from other ships in the vicinity. This is fitted in ships bridge equipment console and helps the navigating officer to conduct the look-out duty as per the International Regulations for Preventing Collisions at Sea.

17. Navigational Lights

All boats – whether big or small are required to have night lights as a part of the navigation systems. This system was introduced in the year 1838 by the United States and then was followed by the United Kingdom in 1849. In the year 1889, the International Maritime Conference was established by the United States to establish proper guidelines to prevent marine accidents. In the year 1897, these rules were officially adopted internationally. The navigation lights are one of the most critical navigation equipment needed for sailing in high seas as it enables self vessel being clearly visible to other ships in the vicinity.

18. Ship Whistle

A ship’s horn is known as a whistle and it is generally provided in duplicate. One is driven by air and the other is electrically operated. The whistle should be both manually and electrically operational from the bridge.

Among different instruments used in difficult navigation such as bad weather, fog, poor visibility, high traffic etc., the ship’s whistle or horn helps in alerting the nearby vessels.

During an emergency, the horn is used to notify and alert the ship’s crew and other vessels nearby.

19. Daylight Signalling Lamp

They are light-signalling devices used for emergency signalling in the day time (and can also be used during the night). Like other emergency ship instruments, the energy source for the lamp is not solely dependent on the ship’s main power supply. Also, the lamp enclosure should be weather and seawater- proof material.

20. Pilot Card

It is an informative booklet provided to the ship’s pilot. It consists of the dimension, draught, turning circle, manoeuvring, propulsion equipment and other navigation tools and instruments list of the vessel for safe manoeuvring.
