Raymarine B175H-W 20° Bronze Thru-Hull Tilted Element Transducer - 1kW

The Raymarine B175H-W 20° Bronze Thru-Hull Tilted Element Transducer is a 1kW marine depth and temperature sounder engineered for fiberglass and wood-hulled vessels. This thru-hull transducer operates at 150–250 kHz and delivers reliable bottom imaging to 800 feet, making it a dependable choice for recreational anglers and serious offshore fishermen alike. The tilted 20° element design accommodates typical deadrise angles between 16–24°, ensuring accurate readings even on vessels with moderate to pronounced V-shaped hulls.

At 1 kilowatt of transmitted power, this bronze transducer generates strong sonar returns in both shallow flats and deeper offshore structure. The urethane housing resists saltwater corrosion and UV degradation—critical factors for boats operating in challenging marine environments. Installation requires a thru-hull mounting solution compatible with fiberglass or wood construction; the included 6-foot cable provides standard connectivity, though a transducer extension cable may be necessary depending on helm layout. The B175H-W's dual-frequency capability (150 kHz and 250 kHz) balances broad coverage with fine resolution, allowing operators to switch frequencies based on water conditions and target depth.

This transducer suits weekend recreational fishermen seeking basic depth and temperature monitoring as well as experienced anglers who rely on consistent sonar performance for navigation and structure identification. Weekend trips to coastal bays or inland reservoirs benefit from its 800-foot depth capability, while offshore charter operations value the 1kW output's ability to punch through choppy seas and heavy traffic. The 20° tilt accommodates most modern hull designs without requiring extensive modifications, reducing installation complexity and cost. Raymarine's reputation in marine electronics ensures compatibility with their chartplotter and fishfinder ecosystems.
