Icom IC-M37 Marine VHF Portable Radio 6W Float'n Flash Function 700 mW Audio

The Icom IC-M37 is a handheld marine VHF transceiver engineered for full-day on-water operation. It delivers 6 watts of RF output power across standard international, US, Canadian, and weather channel groups, and produces 700 mW of audio output so voice traffic cuts through the ambient noise of a working deck. The radio carries an IP57 rating—dust-tight and submersible to 1 meter for 30 minutes—and adds Icom's Float'n Flash technology: if the unit enters the water it floats, activates a visual strobe, and sounds an alarm to aid recovery even at night. The AquaQuake function vibrates the speaker cone to expel water and restore audio clarity after immersion. A supplied BP-296 Li-ion battery pack delivers approximately 12 hours of runtime at a 5:5:90 transmit/receive/standby duty cycle, and a 4-step battery life indicator with low-battery alert gives operators continuous power-level awareness. Large buttons, a slim grip profile, and instant one-touch access to Channel 16 make the IC-M37 well suited for fishing, sailing, and any offshore or coastal application where reliable, intuitive communication is essential.

Key features & benefits

• 6 W RF Output Power — Transmits at 6 watts across the 156.025–157.425 MHz TX range, extending usable communication range in open-water environments.
• Float'n Flash Technology — If dropped overboard, the radio floats, flashes a visual alert, and sounds an audible alarm—reducing the risk of loss at sea day or night.
• IP57 Waterproof and Dust-Tight — Rated submersible to 1 meter for 30 minutes and fully dust-tight, so the radio can be used confidently on deck or in challenging outdoor environments.
• AquaQuake Water Draining Function — Vibrates the speaker cone to expel water from the speaker grille after immersion, maintaining clear, intelligible audio output.
• 700 mW Audio Output — High-output audio rated at 700 mW (typical) ensures received voice is clearly audible even in noisy onboard conditions.
• Dualwatch and Tri-Watch Functions — Periodically monitors Channel 16 while operating on a working or call channel, keeping the operator aware of priority traffic at all times.
• Weather Channels with Weather Alert — Receives dedicated WX channels and automatically alerts the operator to incoming weather broadcasts, supporting situational awareness on the water.
• 12-Hour Battery Life — The supplied BP-296 Li-ion battery (3.7 Vdc, 2200 mAh) provides approximately 12 hours of operation at a 5:5:90 TX/RX/standby duty cycle, with a 4-step indicator and low-battery alert.
• Channel History and Favorite Channel Functions — Stores the last five channels used for instant recall, and supports a user-defined Favorite Channel list to streamline frequency management during active operations.
• Large Buttons and Slim Profile — Ergonomic form factor with oversized controls allows confident operation while wearing gloves, and instant one-touch access to Channel 16 ensures rapid response to distress or priority calls.
