The unit floats and emits a flash when submerged, making it easy to spot in the water. More than a radio, however, the iCOM M93D also has a GPS and can take fixes within eight to twelve seconds and stores 50 waypoints. It can calculate location, bearing and speed. The extra-large, high contrast LCD screen and flat, positive-click keyboard, allow for a simple user experience and increase visibility of data in direct sunlight or rough weather. An active noise-canceling feature removes background audio and its “Aqua Quake” system drains water from the speaker and microphone so transmissions will always be crystal clear. Sailors can have security peace of mind knowing that this radio also has an easy to access Class D distress call system using a rear panel button, can receive weather alerts and a battery life up to 9 hours.
