Never Be Left Unprepared - The Cobra MR-HH125

Boating, fishing, skiing, jet skis... Fun and relaxing recreational activities that many of us like to enjoy and partake in. But there are times when these fun activities can become dangerous and life threatening and it's better to be prepared in advance than to have to figure what to do during the disaster. That's where a Cobra marine radio comes in. Cobra is one of the most respected and trusted names in radio communication and the MR-HH125 lives up to the expectations and standards that Cobra has set in the past. You'll always be prepared for the worst with the MR-HH125, whether it's a rough unexpected storm or if your vessel or someone else's vessel breaks down out at sea. Receive instant alerts about rough weather with the built-in NOAA receiver and take some of the unexpected out of the open ocean. And with its Dual Watch Mode, you can constantly monitor the Channel 16 emergency channel and one other channel to be aware of any mayday and distress calls. When the fun turns to disaster, the Cobra MR-HH125 will keep you and your passengers safe.

Handheld Radio Specifications

Built-In NOAA Receiver
CB radios with this feature have the ability to access local NOAA radio stations for real-time weather reports and updates. CB radios equipped with multiple NOAA channels allow users to select the clearest channel to monitor weather conditions.
Illuminated / Backlit Display
Some models include a backlit radio display for convenient operation at night. This is an invaluable feature if a radio will be used extensively at night or in dark conditions.
AM/FM Tuner
Adjustable Output Power
Allows users to increase or decrease the transmit power of the CB radio. At a higher transmit power the signal will travel farther. In battery powered radios, users may want to lower the transmit power in order to increase battery life.
Squelch Control
Changes the sensitivity of your CB radio to adjust for whatever signal strength you may be receiving. Lower squelch levels will allow you to receive transmissions from a greater distance, but these transmissions will contain more background noise. Higher squelch levels reduce the background noise, but will eliminate some weaker transmissionsl. In effect, it keeps the receiver from constantly having to listen to static and only activates the speaker when a transmission is received.
Voice Activation
Signal Strength Meter
This feature displays the strength of the received or transmitted signal.
Lock Mode
Channel Scanning
primarily for recreational purposes, allows you to automatically scan all available CB channels for activity, ensuring you'll know of anything happening on the airwaves.
Dual Watch
Allows you to monitor two channels at once.
Emergency Crank
External Speaker Output
Microphone Input

I've just purchased a Cobra MR-HH125 W VHF hand-held radio and want to know if there is available a charger that I can plug into 110V in my home to charge the radio instead of having to plug in to my power outlet in my vehicle? Thanks for any help. Dennis
Dennis B on May 14, 2015
Best Answer: I actually got tired of the recharge hassle. I keep an alternate set of regular rechargeable batteries and swap every trip out.
