Navman Simrad B258 Fishfinder Transducer B258-6N

The B258 is a 1kW bronze thru-hull fishfinder transducer with temperature sensor and an external fairing that can be cut to match the hull deadrise angle. Its four ceramic elements give much greater sensitivity than a single-element transducer. The B258 is ideal for enhancing the performance of 600W sounders and fishfinders.

The B258 is shipped as a generic 'Mix and Match' transducer plus a brand-specific adapter cable. If you change fishfinder brands in the future, you can continue to use the transducer with a new adapter cable.

This '-6N' version of the transducer is for Navman sounders and fishfinders that use the Navman 6-pin transducer connector, including the M121, M81, and the Explorer series, and the Simrad NX.
