Airmar B175M Transducer CHIRP Bronze 0° Tilt 1kW

Overview

Who This Is For: Tournament anglers, charter captains, and serious recreational fishermen running fiberglass or wood hulls up to 36 feet who need surgical-precision bottom detection and fish separation at depth. If you're fishing structure, suspended baitfish, or need to distinguish individual gamefish from the noise, this transducer delivers the resolution to see what others miss.

Product Summary: The B175M is a thru-hull CHIRP transducer built on Airmar's broadband architecture — meaning one installation gives you 50 kHz of total bandwidth with dual frequencies (88 and 107 kHz) plus everything in between. You get bottom detection to 10,000 feet, 5 to 10 times greater detail than traditional single-frequency transducers, and the ability to pick individual baitfish out of a school. At 1kW power, it delivers clean, fast-response data even in rough water or at speed.

Key Features

• CHIRP Broadband (85–135 kHz) — transmits across a 50 kHz bandwidth in a single installation — you see substrate detail, fish size variation, and structure separation that single-frequency transducers simply can't resolve.
• Dual-Frequency Coverage (88 & 107 kHz) — covers the frequencies most fish finders use, with full bandwidth in between — flexibility to tune your display for shallow structure or deep offshore work without swapping hardware.
• 1 kW Power Output — strong, clean signal penetration even in rough seas, stained water, or at high boat speeds — your screen stays crisp and responsive when conditions matter most.
• Depth Capability to 10,000 Feet — whether you're working 50-foot coastal structure or dropping into the abyss, this transducer reaches it — no limitations based on hull depth or water column.
• Bronze Thru-Hull Housing — corrosion-resistant construction rated for saltwater and freshwater; 0° tilt angle mounts flush for minimal drag — proven durability with no performance sacrifice.
• Integrated Water-Temperature Sensor — fast-response readings track thermal breaks and seasonal patterns without a separate sensor installation.
• Xducer ID Technology — automatic transducer recognition and configuration — plug it in and your fish finder knows exactly what you've installed, eliminating guesswork on your setup screen.

Specs & What's Included

Compatibility: Works with any CHIRP-capable fish finder that supports Airmar transducers — including Humminbird, Lowrance, Simrad, and Garmin systems with appropriate transducer connectors. Your fish finder's display must support broadband CHIRP frequencies in the 85–135 kHz range to unlock full capability. Not sure if this works with your setup? Call or text us at (833) 831-4077 — we'll tell you straight.

In the Box: B175M bronze thru-hull transducer only. You'll need to purchase a compatible Mix and Match transducer cable separately — the cable connects to your fish finder's transducer port and must match both your transducer connector type and your display unit.
