Full DSC Distress Calling — No External GPS Required
The Cobra MRF77BGPS is a fixed-mount Class D DSC VHF radio with an integrated GPS receiver, which means your exact position is automatically embedded in every DSC distress call — no separate GPS unit, no wiring, no setup. In an emergency, that's the difference between a rescue team knowing where you are and having to search for you.
Beyond safety, the MRF77BGPS adds Cobra's Rewind-Say-Again® feature, which lets you replay the last 20 seconds of received audio — so you never miss a critical call in rough conditions or a noisy helm. It includes both flush-mount and fixed-mount hardware kits, giving you installation flexibility right out of the box.

Parts Desk Insights
Best use case: This is the right radio for boaters who want true standalone DSC distress capability — no chartplotter, no external GPS, no additional wiring required. The built-in GPS means your position goes out with every distress call automatically, which is the single most important feature in a real emergency. It's the smart upgrade for anyone currently running a VHF radio that requires an external GPS connection for DSC to work. The Rewind-Say-Again® feature is also genuinely useful at a busy or noisy helm. If you don't need built-in GPS and want to save some budget, the Cobra MRF45D is the step-down option. For a handheld backup, the Cobra Bluebound 350 Floating Handheld VHF pairs well with this radio as a second unit.
