Meet the Airmar B175MW Medium Ultra-Wide 20-Degree 1kW CHIRP Transducer—a Tilted Element™ thru-hull solution designed for serious pelagic action. CHIRP-ready and built to pair with Mix & Match cables, it delivers broad water-column coverage and precise mid-depth targets for focused trolling and scanning.
-
Through-hull Bronze Housing: Compatible with fiberglass or wooden hulls and vessels up to 11 m (36') LOA; this low-profile bronze housing minimizes drag while maintaining solid speed resolution.
-
Tilted Element 20°: 20° tilt compensates for hull deadrise and orients the element for optimal returns; available in 20° (also offered in 12° or 0° variants).
-
Power and Depth Capability: 1 kW CHIRP transducer with depth tracking down to 400 m (1,300 ft) for mid-depth pelagic exploration.
-
Medium Ultra-Wide Beam: 60–100 kHz frequency with a broad beam of 57°–73° port/starboard and about 16° average fore/aft for expansive water-column coverage.
-
Single-band CHIRP and Bandwidth: CHIRP-ready operation with 40 kHz total bandwidth from a single transducer for versatile performance.
-
Cable, Hole Size, and Hull Fit: 9 m (30 ft) cable; 95 mm (3-3/4") hole size; designed for hulls up to 11 m LOA and compatible with a wide range of hulls.
-
Xducer ID and Built-in Sensors: Xducer ID technology for easy, reliable transducer recognition and setup; depth and water-temperature sensors provide quick environmental data on the fly.
-
Weight and Design: Lightweight at about 2.7 kg (6 lb), engineered to deliver crisp resolution at speed with a robust, reliable thru-hull form factor.
-
Mix & Match Cable Requirement: Note: requires a Mix & Match Cable for setup.
The B175MW is engineered for serious mid-depth exploration, delivering precise echoes and broad sonar coverage for pelagic species in the upper water column. Its low-profile through-hull design minimizes drag while maintaining speed resolution, and built-in environmental data supports quick on-water decisions. With CHIRP-ready performance, a wide 60–100 kHz range, and Xducer ID for simple setup, this transducer offers a capable, adaptable solution for fiberglass or wooden hulls up to 36 feet.
