The B285’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 up to 457 m (1500') and gives ultra-clear target resolution.

This model is also ideal for single-channel sounder applications where operating in Chirp mode provides a greater opportunity to see what is in the water column. Simply create pre-sets for 85 and 135 kHz and toggle between wide and narrow beams for scouting an area and then pinpointing structure.

The included High-performance Fairing improves broadband performance at speeds over 30 knots (34 MPH).

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.
