Thru-Hull mount, dual angle, 50/200 kHz 1000W depth/temperature transducer with fairing. fits all Lowrance HDS 50/200 kHz fishfinder or combo units with Lowrance Blue connectors, come with 10 meter (33ft) cable and plug.

Works with: Lowrance HDS fishfinder and combo model list below:

Lowrance: HDS-5x, HDS-5, HDS-7, HDS-8, HDS-10

The B258 is a 1000 watt depth and temperature bronze thru-hull fishfinder with an external fairing that can be cut to match the hull deadrise angle. Its unique ceramic-element construction gives it 25 times the sensitivity of a single-element 50/200kHz transducer. The resulting narrow elliptical beams will clearly distinguish individual fish and bottom fish from their habitat at up to 3000-5000 ft.

 Airmar Comparison of Transducer Performance

 • B744V, B744VL : 600 W Good : Single-element model, benchmark for comparison 
• B164 : 1kW Better : 6 times more sensitive at 50 kHz, 2 times more sensitive at 200 kHz 
• B258 : 1 kW Better : 25 times more sensitive at 50 kHz, 16 times more sensitive at 200 kHz
