B258 1kW 50/200kHz Thru-hull Transducer 

(Excludes Transducer Fairing)

The B258 is 25 times more sensitive than a single-element 50/200 kHz transducer. This innovative 1 kW transducer makes 600 W fishfinders perform like their more powerful big brothers—especially at 50 kHz. How does it do it? The B258 uses Airmar’s new and unique ceramic-element construction. The resulting narrow beams will clearly distinguish individual fish and bottom fish from their habitat at Depths down to 670 m (2,200’).

Maximize performance by installing the B258 with Airmar’s custom fit High-Performance Fairing. At speeds over 30 knots (34 MPH), screen displays show clear images and a clean bottom trace. 

Key Features

• Elliptical beam covers more bottom area thus increasing your catch at all depths
• Depth and fast-response water-temperature sensor
• Recommended for sportfishing boats above 9 m (30’) and small to mid-size commercial fishing boats
• Four 50/200 kHz ceramics as compared to one ceramic in 600 W units
• Provides greater surface area resulting in better sensitivity
