Raymarine B175M Bronze 1kW CHIRP 20° Tilt

The Raymarine B175M Bronze 1kW CHIRP 20° Tilt transducer delivers professional-grade fish detection and bottom mapping for serious anglers and commercial operators. This bronze through-hull transducer combines Airmar's broadband CHIRP technology with 1kW output power, enabling bottom detection down to 3,000 meters with exceptional target separation and structural detail that distinguishes individual baitfish from gamefish and underwater terrain.

The 20° tilt mounting configuration accommodates various hull angles on fishing vessels and charter boats, while the bronze construction provides superior corrosion resistance in saltwater environments where aluminum transducers degrade rapidly. CHIRP frequency sweep technology generates 5–10 times greater resolution than conventional single-frequency sounders, producing layered acoustic imagery that reveals baitfish schools, structure, and bottom composition with clarity that changes how fish location decisions are made. The 1kW power rating ensures strong sonar return from shallow-water structure and mid-depth pelagic species.

Tournament anglers, charter captains, and commercial fishermen depend on the B175M Bronze when offshore conditions demand dependable transducer performance and accurate target identification. The through-hull installation provides stable sonar signal free from transom-cavity turbulence, making this transducer the choice for vessels where consistent deep-water detection and competitive fishing data are non-negotiable. Weekend recreational fishermen also benefit from CHIRP clarity when fishing unfamiliar structure or pursuing multiple species on the same outing.

Raymarine transducers integrate directly with compatible Raymarine multifunction displays and Airmar-certified sounder systems. Verify mounting compatibility and installation requirements before purchase, as transducer selection depends on hull material, thickness, and preferred tilt angle for optimal sonar cone alignment and bottom tracking performance.
