Airmar B258

B258 - Bronze 1kW Fairing-Block Through-Hull 50/200 kHz Depth/Temperature Transducer.

The B258 is an excellent, economical, 1 kW, dual-frequency transducer for anglers. Its unique four ceramic-element construction produces an elliptical beam that covers a wider area and produces excellent target resolution. The combination of 50 and 200 kHz make it a great option for both shallow and deep-water use. The included high-performance fairing gives excellent results at speeds up to 30 knots (34 MPH).
