The Raymarine B175L is a bronze low-profile thru-hull transducer built for serious offshore fishing and deep-water bottom tracking. Its 20° tilted element design compensates for hull deadrise angles between 16° and 24°, keeping the beam perpendicular to the water for accurate returns. Paired with a CP450C or CP470 CHIRP Sonar Module, it delivers 1kW of power and a maximum depth capability of 2,500 feet — well suited to canyon fishing and deep-structure work common in Pacific Northwest and offshore blue-water environments.
