Overview
1 kW The B175M’s medium frequency delivers the right combination of coverage under the boat, extended depth range, and the ability to produce clean and accurate target and structure returns in mid to deeper water.
Medium frequency also provides excellent shallow to mid-depth performance, bottom detail, and fish-target separation.
Operating at a frequency range of 85 to 135 kHz, this transducer reveals fish at medium depths of up to 457 m (1500′) and gives ultra-clear target resolution. Airmar’s Tilted Element ™ transducers have the element fixed at a 20°, 12°, or 0° angle within the housing. Because the transducer is installed almost flush to the hull, the tilt corrects for the hull deadrise.
It orients the ceramic element horizontally to ensure maximum echo returns to the transducer.
The B175M is available in three Tilted Element models: Fixed 20° tilted version for 16 to 24° hull deadrise angles Fixed 12° tilted version for 8 to 15° hull deadrise angles Fixed 0° tilted version for 0 to 7° hull deadrise angles This transducer is available in two options: one with an OEM connector designed specifically for your fishfinder, and another as a Mix and Match™ Transducer version.
The Mix and Match™ transducer has a 9-meter (29.5’) cable with a standard connector, plus a 1-meter (3’) adapter cable to connect it to your fishfinder. When placing your order, make sure you know which connector type your fishfinder requires.
