Cobra MR HH600B: Floating Handheld VHF Radio with DSC, GPS, and Bluetooth

Meet the Cobra MR HH600B, a rugged, floating handheld VHF radio built for the demands of real-world marine adventures. Designed to keep you connected, informed, and safe, this compact unit blends essential marine communication with smart features that matter when it counts—whether you’re crossing open water, docking at a marina, or back at the helm after a long day on the water.

Why it stands out

• DSC with internal GPS — When you trigger a distress call, the MR HH600B automatically includes your precise position, speeding up rescue and coordination during urgent moments. This seamless integration of GPS data into DSC transmissions isn’t just convenient—it’s lifesaving.
• Floating, highly visible design — An orange core and buoyant housing make this radio easy to spot and retrieve if it slips overboard, reducing stress during a rough moment on deck or near the swim platform.
• 6 Watt VHF with flexible power — Switch among 1, 3, or 6 watts to optimize range and battery life for the situation, from tight marina channels to offshore crossings.
• NOAA Weather access — Instantly access National Weather Channels and emergency alerts to stay ahead of changing conditions and plan safer routes to your next waypoint.
• Rewind-Say-Again — Missed an important call? Rewind and replay recent transmissions so you don’t miss critical instructions or distress signals.
• Advanced navigation aids — Built-in digital compass, waypoint navigation, course, and speed keep you on track, even when you’re plotting a new course from the cockpit or flybridge.
• NMEA Out for chartplotters — Transmit DSC or vessel information to your chartplotter or other displays for a unified, at-a-glance situational picture.
• Tri-Watch and Channel Access — Monitor Channel 16 (hailing), Channel 9 (emergency), and a third channel simultaneously for broad situational awareness on every voyage.
• MOB protection with noise-canceling mic — Clear, hands-free communication in windy, noisy conditions and rapid response to man-overboard events.
• Rugged, water-ready build — IPX8 waterproof rating protects against immersion up to 3.3 ft (1 m) for 30 minutes, plus BURP water-expulsion keeps the speaker grill clear after splashes.
• Bluetooth and hands-free convenience — MicroBlue Bluetooth enables voice dialing, easy redial, and hands-free calls when you’re aboard or on shore leave.
• AA battery compatibility — An emergency battery option with a tray included ensures you’re never without a communication lifeline, plus a complete charging setup (120V/12V charger and locking desktop charger) for flexibility on land or sea.

Practical use cases

• Coastal and offshore sailors rely on DSC with GPS to summon help precisely where you are, even in poor visibility or rough seas.
• NOAA weather alerts help you anticipate squalls, fog, or shifting winds while you’re plotting a new course or approaching the next harbor point.
• Rewind-Say-Again ensures you can catch up on critical calls if you momentarily miss a transmission during busy deck operations.
• NMEA Out enables a unified navigation setup, displaying your position and radio data on compatible chartplotters for a single, clear operational picture.
• Tri-Watch keeps you connected to hailing channels and safety channels while maintaining awareness on the water around you.

Who this is for

Ideal for coastally oriented sailors, offshore anglers, and boaters who prioritize reliability, safety, and seamless integration with navigation gear. If you value automatic GPS tagging in distress calls, flexible power for varying ranges, and a radio that stays with you from launch to landfall, this is the handheld you’ll reach for first.

Smart design meets practical performance

The MR HH600B isn’t just a radio—it’s a connected safety system that bridges voice communication with navigation data. Its floating form, buoyant visibility, and robust weather features are matched by thoughtful touches like BURP expulsion and a noise-canceling mic for clear conversations even in blustery conditions. The combination of DSC with GPS, NMEA Out, and Bluetooth turns a handheld radio into a central node for your marine electronics, reducing complexity while increasing safety and situational awareness.

Real-world setup tips

• Pair with a chartplotter via NMEA Out to display your DSC data and position in one cockpit view.
• Configure Channel 16 for hails and Channel 9 for emergencies, while keeping a third channel active for quick checks during busy days on the water.
• Use the 6W setting for offshore or open-water segments where range matters; switch to 1W for tight marina channels to conserve battery life.
• Keep the built-in GPS updated for accurate distress location tagging and precise navigation aids.
• Charge with the full 120V/12V charger and locking desktop dock to ensure the radio is ready for the next voyage, with AA backups available for extended trips.

With the Cobra MR HH600B, you’re not just choosing a handheld VHF radio—you’re choosing a trusted marine companion designed to keep you safer, more informed, and more connected on every voyage.
