The B285M’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).
