Upgrade your marine fishfinding performance without drilling into your boat. The Airmar M135M is a high-performance, 1 kW CHIRP-ready in-hull transducer designed specifically for solid fiberglass hulls up to 11 meters (36 feet) long. By operating inside the bilge, it eliminates exterior drag, protects against impact damage, and delivers crystal-clear sonar readings at any speed.
Operating on a medium frequency range of 85 to 135 kHz, the M135M excels at finding fish and defining bottom structures in shallow, murky, or mid-depth waters down to 457 meters (1,500 feet). Its internal ceramic array automatically adjusts beamwidth from 16° to 11° to optimize target separation as your depth changes.
