Airmar B258 1kW Bronze D/T Thru Hull - Northstar

Sport fishermen get excellent 1 kW performance with the moderately-priced B258. Its economical, four-ceramic-element construction puts out a narrow beam for good deep-water capability with very good target and bottom definition.

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’).
