B265LM Chirp-ready Thru‑hull

1 kW

The B265LM, Chirp-ready transducer is a perfect, mid to deep-depth transducer. The huge bandwidth includes many of the most popular frequencies for targeting top gamefish. This 1 kW, powerhouse delivers clear target details, bottom discrimination, as well as bait and game-fish separation at all depths. The low-frequency band provides deep-water performance down to 914 m (3,000′) and is a good choice when scouting an area or fishing in deeper depths. The medium-frequency band is excellent for identifying targets suspended close to the bottom, on structure, and within the water column.

The included, high-performance fairing improves broadband performance at speeds over 30 knots (34 MPH).

Low frequency 42 to 65 kHz, Medium frequency 85 to 135 kHz
