What Is the Best Handheld Marine VHF Radio of 2021?

A day out on the boat started out so good. Then the weather turned bad and now there's a big storm.

The power on board doesn't work and the engines are failing. The wind and current are quickly taking the boat out to sea.

This is a dangerous situation. An emergency rescue needs to happen. But how?

This is the exact situation when a VHF radio could save lives. We've evaluated and compiled a list of the best handheld VHF radios.

What Are Marine VHF Radios?

VHF radios are the main method of maritime communication. They allow boats to communicate with each other and emergency services.

They operate by using radio waves to send information back and forth. The waves travel a certain distance depending on the power supplied and obstacles.

Cell Phone or VHF Radio

Cell phones are reliant on cell towers for a signal. Travel a few miles off the coast and a cell phone will lose its ability to function.

This renders a cell phone useless in an emergency situation. Cell phones are not the quickest way to contact the Coast Gaurd.

The Coast Gaurd is set up to receive distress calls through the VHF radio system. Rescue help will mobilize faster with the correct communication channels.

Features to Consider

When looking at features, keep in mind which ones are going to be most useful for the type of boating intended. Boaters who plan to stay inshore do not need all of the features available.


Digital Selective Calling is the standard form of communication for automatic maritime distress alerts. Rescue services across the world are set up to receive and respond to these calls.

A boat's GPS location is automatically sent out with the distress call. Messages on the DSC network are similar to a text message.

These messages go out to rescue services, ports, and vessels nearby. Boaters that travel internationally must have this type of communication on board.

Be sure to register for a unique Maritime Mobile Service Identity (MMSI) Number. This is the boat's ID when communicating on the network.


This feature can work on its own or in conjunction with DSC and AIS. It will track and provide information on the boat's exact latitude and longitude.


AIS stands for Automatic Identification System. This is an automated and autonomous tracking system.

All boats that travel internationally must carry a transponder. The transponders collect data such as the vessel's size, speed, location, and destination.

The information is broadcast out at regular intervals to other nearby transponders. The information sent from other vessels gets compiled into a single report.

A chart displays the compiled data for tracking purposes. This tracking prevents collisions and regulates marine traffic in ports.


Scanning is the ability for a VHF radio to check more than one channel at a time. Boaters are legally required to monitor channel 16 at all times.

This is the emergency distress channel. Scanning more than one channel lets boaters follow the law.


The easiest way to prevent a boating emergency is to pay attention to the weather. VHF radios provide up to date information on severe weather alerts from both NOAA and SAME.

Noise Cancelling

Nothing is worse than trying to talk to someone and all you hear is static. Noise-canceling or squelch screens out the static and ambient noise.

Standard Horizon HX870

The HX870 makes this list thanks to its many features, large display, and usability. This handheld VHF radio is perfect for boaters who travel far away from the coastline.


The Horizon radio has GPS that automatically tracks a vessel's movement and location. Tracking formation is automatically sent when a user triggers a distress call.


The device can track 9 pre-selected vessels that are in the vicinity. Navigate to the compass page on the display to track their movements.


The menu is intuitive with everything accessible within a few steps. The screen is one of the largest available on handheld VHF radios.

It measures 1.7" wide by 1.7" tall and 2.3" diagonal. The dot matrix display provides higher resolution. The screen is backlit which makes reading it easy to see day or not.


Program ten favorite channels for quick selection. All USA and Canadian marine channels are available for use.

Program the scanning function to dedicate a priority channel. Then program either dual or tri watch for extra channels.


This handheld radio floats but is also rated for submersion in up to 5 feet of water for thirty minutes. Contact with water triggers a strobe light to flash.

Power Options

Choose between 1, 2, and 6 watts of power. This is useful for communication with nearby and far away boats.

Lower the power level to 1 watt to communicate with nearby vessels. This won't disrupt vessels that are further away. Raise the power to 6 watts for more distance.


The battery is an 1800 mAh Li-Ion Battery. It can be fully charged in three hours.

Uniden MHS75

The housing for the Uniden is a tough die-cast aluminum. This gives the handheld a rugged and tough exterior.

Display and Functions

Two large knobs on the top control the volume and squelch. Eight buttons on the front control the rest of the functions.

To keep the display compact, each of the eight buttons performs two functions. The device is easy to use with each of the function labeled on and below each button.

The battery power level has a display on the main screen. When the battery level gets low the screen will flash and an audible alarm will sound.


Choose between 1, 2.5, and 5 watts for short and long-range communication. The lower power outputs of 1 and 2 watts will extend the battery life. The battery will last twelve hours with regular use.


The radio is compatible with USA, Canadian, and International marine channels. There are also 10 weather channels available from NOAA.

Compact Size

The compact size is 2.5 x 4.6 x 1.5 inches and weight of 10.4 ounces. This makes it the perfect size to carry it on a belt.
