Airmar B175H Transducer Bronze Thru-Hull CHIRP 12°

Overview

Built for serious anglers running center consoles and smaller boats who need high-frequency precision without the bulk. If you're working shallow structure—reefs, wrecks, tight bottom—and want to separate individual fish from baitballs at a glance, this transducer is purpose-built for that job.

The B175H is a thru-hull CHIRP transducer that delivers narrow-beam, high-frequency sonar in a low-profile bronze housing. You get 80 kHz of total bandwidth from a single transducer, meaning superior shallow-water detail and bottom definition. The tilted element corrects for your hull's deadrise automatically, so you get clean echoes even at speed—no guesswork about installation angle.

Key Features

• High-Frequency CHIRP (130–210 kHz) — transmits across 80 kHz of bandwidth from one transducer — gives you exceptional target separation on schooling fish and detailed bottom structure, especially in shallow water where most tournament bass and inshore anglers fish.
• Narrow Beamwidth (10° to 6°) — focuses your sonar beam tight — means you see fish holding hard against wrecks, pilings, and reef edges instead of false echoes from surrounding water.
• Tilted Element Design — ceramic element is fixed at 12° inside the housing — automatically corrects for 8° to 15° hull deadrise, so you get maximum echo return without manual adjustment or underwater installation complexity.
• 1 kW Power with 1000' Max Depth — punches through deep water when you need it, but optimized for shallow-to-medium depths where you'll spend most of your time hunting structure.
• Low-Profile Thru-Hull Housing — flushes nearly flat to your hull — minimizes drag at speed and keeps bottom detail clean even when you're running hard to the next waypoint.
• Depth and Temperature Sensing — dual functions built in — no need for a separate temp sensor if your fishfinder accepts temperature input from the transducer.

Specs & What's Included

Compatibility: The B175H connects via 8-pin connector and works with most Airmar-compatible fishfinders (Simrad, Lowrance, Navico systems). It's CHIRP-ready, meaning your unit must support CHIRP frequency sweep or you'll operate it in traditional single-frequency mode. The transducer is rated for fiberglass or wood hulls with 8° to 15° deadrise; maximum deadrise tolerance is 24°. Recommended for boats up to 11 meters (36 feet).

In the Box: B175H bronze thru-hull transducer with 8-pin connector and 71 mm (2.80") usable shaft length. Installation hardware (sealing washer, fasteners) and transducer cable are typically sold separately; verify with your fishfinder manufacturer or call us to confirm what's needed for your installation.
