The B150M delivers a great combination of shallow and deep-water performance. Operating at a frequency range of 95 to 155 kHz, this transducer reveals fish in shallow waters and deeper depths out to 183 m (600') with ultra-clear target resolution. Tilted Element™ transducers have the ceramic element fixed at a 20°, 12° or 0° angle within the housing. The transducer is installed almost flush to the hull. The tilt of the element corrects for the hull deadrise by orienting the beam directly down. This ensures maximum echo returns to the transducer for more accurate depth readings. Available in three Tilted Element models: Fixed 20° tilted version for 16° to 24° hull deadrise Fixed 12° tilted version for 8° to 15° hull deadrise Fixed 0° tilted version for 0° to 7° hull deadrise Features Depth and fast-response water-temperature sensor 300 W with depth performance to 183 m (600') Medium frequency: 95 to 155 kHz 26° to 17° beamwidths put more energy on targets for great target separation 60 kHz of total bandwidth from one transducer ideal for inshore or coastal fishing Narrow beam angles are perfect for detecting fish holding close to structures and suspended fish Ideal for freshwater, inshore or coastal fishing in shallow to medium depths Low-profile, thru-hull housing provides good resolution at speed when installed properly Bronze housing for use on stepped, planing or displacement hull Also available in a transom-mount (TM150M)
