Overview
1 kW 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).
