Marine Radios: A Must-Have for Every Boater


What is a Marine Radio?

Whether you’re cruising a lake or out at sea, a marine radio is an essential piece of equipment, navigation, and safety equipment that might just save your life in an emergency. Part of an international system of two-way radio transceivers, marine radios let you communicate with the Coast Guard, other watercraft, or people on shore.

Because they use very high frequency (VHF) FM channels, marine radios are also referred to as VHF radios. Boaters have access to a variety of useful channels that empower them to monitor their surroundings. And if you’re using a Cobra Marine Radio models MR F 77 models and MR HH 600 models with the innovative feature of a built in GPS chip, you have the ability to send position information and distress signals at the touch of a button without your VFH radio being wired to a GPS.

Marine Radios vs. Cell Phones

Would you take a road trip without your cell phone? Every recreational boater should have a marine radio, even when it’s not required by law, so you can easily make distress calls, get up-to-the-minute weather reports, check-in with other nearby vessels, and more. (Or so you can use the phonetic alphabet and say fun things like “over and out.”) 

Your cell phone may be good enough for driving, but it is not reliable on the water. Chances are you won’t have reception when you need it, and if it gets wet or the battery drains, you’re in trouble. Not to mention the many additional features and benefits marine radios offer that cell phones simply can’t.

With a marine radio, boat owners can stay informed with channels for:
International Distress, Safety, and Calling
Coast Guard Liaison and Maritime Safety Information Broadcasts
Non-commercial Inter-ship Communication
NOAA Weather Radio Broadcasts
And more 

What to Look For in a Marine Radio

Available as fixed-mount units or portable walkie-talkie style devices, marine radios come with a range of basic to advanced features. Cobra Marine Radios take advantage of the latest technologies to ensure your marine radio is powerful, dependable, and incredibly easy to use.

For maximum safety, peace of mind, and enjoyment on the water, look for a combination of the following marine radio features: 


Make and receive calls directly from your marine radio. The handheld Cobra MR HH600 radio features Bluetooth capabilities so your phone stays dry.

Built-In GPS

Your marine radio instantly knows your coordinates for sending distress signals. The advanced Cobra MRF77B GPS has an integrated GPS receiver keeping tabs on your exact location.

Weather Alerts
Instant, 24-hour access to national All-Hazards and weather information with all NOAA weather channels. Audible tones and visual alerts let you know if nasty weather is approaching.

Digital Selective Calling (DSC)
Send distress signals and exchange position information with other boats or stations at the touch of a button. The Cobra MRF45D is DSC-capable for ultimate safety.

Automatically records the last 20 seconds of VHF calls so you can always play back what you missed. The Cobra MR HH450 DUAL All-Terrain-Radio utilizes the rewind feature so you don’t miss a word.
