Airmar B175H Transducer CHIRP Bronze Thru Hull 12° Tilt

Overview

Built for serious anglers running fiberglass or wood hulls up to 36 feet who demand maximum sonar detail from a single transducer installation. Whether you're chasing walleye, bass, or saltwater species, this bronze thru-hull transducer pairs the clarity of CHIRP broadband frequency with enough power to paint the bottom in 3,000 meters of water.

The B175H delivers 80 kHz of total bandwidth through one installation point, giving you exceptional target separation and the ability to distinguish individual baitfish from gamefish in a school. That's not just more information—it's the difference between marking fish and catching them.

Key Features

• CHIRP Broadband Frequency (130–210 kHz) — transmits across a wide range of frequencies in a single ping — you get 5 to 10 times greater detail and resolution than traditional single-frequency transducers, making it possible to see structure and individual fish with clarity that changes how you fish.
• 80 kHz Total Bandwidth — one transducer delivers the frequency range of multiple units — saves installation time and eliminates the cost and complexity of running multiple transducers.
• 1 kW Power Output — enough muscle to reach bottom in 10,000 feet of water with strong signal return — critical for deep offshore work or clear-water lakes where weak signals get lost in the noise.
• 12° Tilt Angle — optimized for forward-looking sonar performance and reduced dead zones directly under your hull — keeps the transducer reading clean water and active structure instead of turbulence from your boat.
• Integrated Water Temperature Sensor — tracks real-time surface temp with fast response — helps you identify thermoclines and seasonal patterns without a separate temperature probe.
• Bronze Housing — corrosion-resistant in saltwater and freshwater environments — builds durability into a thru-hull installation that'll last.
• Xducer ID Technology — automatic transducer recognition — your sonar unit identifies this transducer and loads the correct frequency responses automatically, eliminating setup guesswork.
