XSONIC Airmar B258
B258 - Bronze 1kW Fairing-Block Through-Hull 50/200 kHz Depth/Temperature Transducer. Black 9pin connector and 10m (33ft) cable
B285M - Bronze 1kW Through Hull Medium-Chirp Depth and Temperature transducer. 9-pin connector and 10m cable.
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. Operating at a frequency range of 85 to 135 kHz, this transducer reveals fish at medium depths up to 457 m (1,500') and delivers 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).
The B285M transmits across the medium-frequency, 85 to 135 kHz band.
