Cobra MR HH350 FLT review

Looking for a radio that is reliable, has a complete set of features and sold at a low price? Cobra’s MRHH350FLT VHF radio is an affordable, compact and lightweight handheld VHF marine radio perfect for people on a tight budget. This is one of the best handheld VHF radios for the money currently available to boaters!a

Let's take a look at some of the features of the Cobra handheld VHF radio.

Floating Compact Design:

Cobra MRHH350 is equipped with an intuitive floating design and orange core that makes retrieval easy and convenient. It has a total measurement of 4.75"H x 2.66"W x 2.09"D and weighs 9.59 oz (with the battery). With its submersible tech (this radio is rated JIS7), it can survive being in one-meter deep waters for 30 minutes. It’s secured with a tough case that prevents internal and external damage if dropped overboard. 

If you’re planning to wear it on your body, Cobra  includes spring-loaded belt clip and there is an external speaker/microphone jack for lapel speaker/mic. Cobra makes CM 330-001 that can be used with this radio as well as other handheld radios (via a special adapter).


The device has a large and bright backlit LCD  screen that displays every critical piece of  information.  Your active channel is shown in 2 large digits, weather icon will display current weather condition, weather alert icon will tell you about critical weather alerts and there is also indicator of your signal level. It does not take long to get accustomed to the display and information on it, since everything is clearly labeled and it is not over-populated with information.


Cobra MRHH350 works in the 156.050 to 163.275 MHz spectrum and works with all USA, Canadian and International channels. The output power is adjustable: 1, 3 and 6 Watts for short and long-range communication. If you are close to the shore or another vessel and don't need the full transmit power, just select the 1W output and conserve the battery energy.

Your further safety is increased with ALL NOAA weather channels with weather alerts. Cobra MRHh350 can monitor up to three channels and get instant access to channel 16 when emergency situations arise.

Integrated  noise-cancelling microphone works well blocking background noises, and there is also a built in BURP function. If the radio is dropped or gets wet, a speaker will vibrate to get the water our of the speaker grill.

Excellent Battery Life:

The device has a long-lasting 1040 mAH Lithium-Ion battery that is capable of 8 hours of operation at the maximum power output (6 Watts) and 16 hours with the 1 Watt output.  This battery has its own level gauge that allows display of battery-shaped icon onscreen along with four-blocked shaped level indicators. It gives the user a flash and audible alarm once the battery is low so you can charge whenever you’re going to use it for longer hours. Cobra did a great job including a desktop charger (with AC adapter) as well as 12V DC accessory plug which gives you even more flexibility. For additional power, you can purchase CM 110-024 adapter, which will  allow you to use regular AA alkaline batteries.
