Never Be Left Unprepared - Cobra MR-HH425LI-VP

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-HH425LI-VP 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-HH425LI-VP, 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 Tri Watch Mode, you can constantly monitor the Channel 16 emergency channel and two other channels to be aware of any mayday and distress calls. Go ahead and save as many channels as you want to the memory, you have unlimited storage options for memory presets as well. Literally, there is no limit to the amount of preset memory channels you can have. If that wasn't enough, the Rewind-Say-Again™ feature will make sure you never miss an important transmission again. Playback the last 20 seconds of any transmission to make sure you got the important details. When the fun turns to disaster, the Cobra MR-HH425LI-VP will keep you and your passengers safe.
