Key Features

• 6-Watt RF Output Power: Maximum legal handheld VHF power provides 50% more output than standard 5-watt radios for extended communication range. The 6-watt transmit power ensures your voice reaches farther, especially critical in emergencies or when operating at maximum range. Selectable high/low power (6W/1W) optimizes battery life when operating at close range while maintaining full power capability for distance communication.
• Float’n Flash Function: Exclusive Icom technology makes the IC-M37 float upright with bright red flashing LED lights on both front and back when dropped in water. The flashing LED is visible from long distances and continues for extended periods to aid retrieval even in rough seas, low light, or nighttime conditions. This critical safety feature prevents expensive radio loss and ensures you can recover your communication lifeline if accidentally dropped overboard.
• 12+ Hours Operating Time: Industry-leading battery life provides more than 12 hours of operation with the included BP-296 Li-ion battery pack (based on 5% TX, 5% RX, 90% standby duty cycle). This exceptional endurance eliminates range anxiety during long days on the water, extended passages, or emergency situations. The user-replaceable BP-296 battery pack allows you to carry spares for virtually unlimited operating time.
• 700mW Audio Output Power: Powerful 700mW internal speaker delivers exceptionally loud, clear audio that cuts through wind noise, engine sounds, and challenging marine environments. The high-power audio ensures you hear critical communications, weather reports, and emergency calls even in noisy conditions. External speaker jack provides 300mW output (4Ω load) for optional external speaker connection.
• IP57 Dust-Protection and Waterproof: Rigorous IP57 rating certifies dust-tight protection and waterproof construction surviving submersion to 1 meter depth for 30 minutes. Exceeds IPX7 waterproof standard. This rugged construction ensures reliable operation during heavy spray, rain, or accidental immersion. The radio continues functioning even after water exposure.
• AquaQuake™ Draining Function: Icom’s exclusive AquaQuake technology uses sound vibrations to clear water from the speaker grill after water exposure. When activated, AquaQuake generates low-frequency vibrations that force water out of the speaker, restoring full audio clarity quickly. This innovative feature prevents muffled audio and ensures the speaker performs optimally even after submersion.
• Large Keys and Easy-to-Grip Design: Oversized buttons with positive tactile feedback enable confident operation while wearing gloves or in rough conditions. The ergonomic chassis design with textured surfaces provides secure grip even when wet. Intuitive button layout places critical functions including 16/C (instant Channel 16/Call channel access) within easy reach. The user-friendly interface reduces learning curve and improves safety.
• Built to MIL-STD-810G Standards: Exceeds rigorous U.S. Military Standard 810G specifications for environmental durability including low pressure (Method 500.5), high temperature (501.5), low temperature (502.5), temperature shock (503.5), solar radiation (505.5), rain blowing/drip (506.5), humidity (507.5), salt fog (509.5), dust blowing (510.5), immersion (512.5), vibration (514.6), and shock (516.6). This military-grade construction ensures reliable operation in the harshest marine environments from Arctic cold to tropical heat.
• Channel History Function: Automatically stores the last five channels used for instant recall without scrolling through the entire channel list. This time-saving feature allows quick access to frequently used channels for monitoring fishing fleets, marinas, bridge channels, or commonly monitored frequencies. Improves operational efficiency and reduces distraction.
• Instant Channel 16 and Call Channel Access: Dedicated 16/C button provides instant access to emergency Channel 16 or your designated call channel from any channel with a single button press. In emergency situations, this one-button access to Channel 16 saves critical seconds. Press and hold to return to your working channel.
• Voice Loud and Mute Functions: Temporarily maximize volume for important transmissions or instantly mute audio without adjusting volume controls. Voice Loud function temporarily increases volume to maximum regardless of volume setting—perfect for hearing critical communications in noisy environments. Voice Mute temporarily silences audio for private conversations without losing your channel.
• Low Battery Alert: Audible and visual low battery warning provides advance notice before battery depletion, ensuring you’re never caught without communication capability. The alert gives you time to switch to backup batteries or return to the dock before losing power.
• Dualwatch and Tri-Watch Functions: Monitor two channels simultaneously (Dualwatch) or three channels (Tri-Watch) for comprehensive situational awareness. Dualwatch monitors Channel 16 and your selected working channel automatically, ensuring you never miss emergency calls while working other channels. Tri-Watch adds weather channels for complete monitoring coverage.
• Weather Channels with Weather Alert: All 10 NOAA weather radio channels with automatic Weather Alert function. The radio monitors weather channels for 1050Hz alert tones broadcast by the National Weather Service. When severe weather warnings, storm advisories, or marine hazard notifications are issued, the radio activates an audible alarm providing critical advance warning time.
• Favorite Channel Function: Program frequently used channels into favorites memory for quick access without scrolling through the complete channel list. Perfect for tournament anglers, charter captains, or anyone who regularly uses specific channels for fleet coordination, marinas, or local working channels.

Float’n Flash Technology

Icom’s exclusive Float’n Flash technology represents a breakthrough in handheld VHF safety and usability. When the IC-M37 is dropped in water, it floats in an upright position with the display facing up, making it immediately visible. Simultaneously, bright red LED lights on both the front and back of the radio begin flashing, providing a highly visible beacon that can be seen from considerable distances even in rough seas or low-light conditions. The flashing continues for extended periods, giving you ample time to retrieve the radio. This dual-LED design ensures visibility from any angle. Unlike radios that sink or float face-down, the IC-M37’s upright floating orientation makes it easy to spot and grab. The Float’n Flash function operates automatically—no activation required. This innovative safety feature has saved countless radios from being lost overboard and ensures your communication lifeline remains retrievable in any situation.

12+ Hour Battery Endurance

The IC-M37’s industry-leading battery life eliminates range anxiety and ensures communication capability throughout the longest days on the water. The included BP-296 Li-ion battery pack provides more than 12 hours of operating time based on realistic duty cycles (5% transmit, 5% receive, 90% standby). This exceptional endurance means you can leave the dock early and stay out late without worrying about battery depletion. Tournament anglers appreciate all-day communication without battery changes. Cruisers enjoy multi-day passages with minimal charging requirements. The high-capacity 2350mAh battery pack uses modern lithium-ion technology with no memory effect—you can recharge anytime without degrading capacity. The user-replaceable design allows quick battery swaps, and optional spare BP-296 packs provide virtually unlimited operating time for extended voyages or emergency preparedness.

Mil-Spec Durability

The IC-M37 exceeds rigorous U.S. Military Standard 810G specifications across fourteen environmental test methods, ensuring reliable operation in conditions that would disable lesser radios. High temperature testing (up to 60°C/140°F) confirms operation in extreme heat. Low temperature testing (down to -20°C/-4°F) validates Arctic and winter performance. Temperature shock testing verifies the radio survives rapid temperature changes. Solar radiation testing confirms UV resistance and heat buildup tolerance. Rain blowing and drip testing validates performance in heavy weather. Humidity testing ensures tropical climate reliability. Salt fog testing confirms corrosion resistance in harsh marine environments. Dust blowing testing validates sealed construction. Immersion testing exceeds IP57 waterproof requirements. Vibration testing confirms structural integrity under continuous vibration. Shock testing validates drop resistance and impact survival. This comprehensive military-standard testing provides confidence for the most demanding marine applications.
