Simrad Bronze Thru-Hull Transducer 9-Pin.

Simrad Thru-Hull Transducers: B258 Bronze and xSonic Airmar B45

Product Description

Simrad’s B258 Bronze Thru-Hull transducer is a powerful 1kW RMS depth and temperature sensor designed for fast sportfishing vessels that can accommodate a thru-hull transducer with a fairing. It operates on dual frequencies, 50 kHz and 200 kHz, enabling excellent bottom and structure fishing capabilities in both shallow and deep waters, up to 500 meters (1640 feet). It provides highly accurate echosounding data even at speeds over 30 knots, with depth and temperature calculations from a compact bronze housing built to withstand harsh marine environments.

The Simrad xSonic Airmar B45 is another bronze thru-hull depth/temperature transducer operating at 50/200 kHz sonar frequencies, suitable for similar marine applications requiring precise water depth and temperature measurements.
