Airmar B75M Transducer CHIRP 12° Tilt 600W

Overview

Built for serious anglers running boats up to 25 feet who need tournament-grade target separation and bottom definition. If you fish structure-heavy water—rocky points, timber, suspended baitfish—and want to distinguish individual fish from the noise, this transducer delivers the resolution to make that call.

The B75M is a CHIRP thru-hull transducer that broadcasts across 50 kHz of total bandwidth, covering the popular 88 and 107 kHz fishing frequencies in a single installation. You get 5 to 10 times greater detail than single-frequency transducers, capable of detecting structure and fish down to 10,000 feet. The 12-degree tilt installation angle works with fiberglass and wood hulls, and the bronze housing handles saltwater corrosion.

Key Features

• CHIRP 80–130 kHz bandwidth — broadcasts across a spectrum of frequencies in one pulse, not just one fixed frequency — gives you exceptional target separation so you can see individual baitfish and gamefish instead of blobs on the screen.
• 50 kHz total bandwidth — covers both 88 and 107 kHz popular fishing frequencies plus everything in between — you won't need to swap transducers to dial in your preferred frequencies.
• 5 to 10x greater resolution — CHIRP technology delivers photographic-level detail of structure, suspended fish, and bottom composition — the difference between a guess and a confident cast.
• Depth capability to 10,000 feet — built for open water and deep structure fishing — more range than you'll need on most freshwater lakes, and ready if you take the boat offshore.
• 12-degree tilt installation — matches most modern hull designs for optimal sonar cone coverage — reduces dead zones and improves shallow-water target definition.
• Integrated water temperature sensor — real-time thermocline and thermal layer data without a separate sensor — helps you locate baitfish and active feeding zones.
• Bronze housing — designed to survive saltwater and heavy use without corrosion — peace of mind if you fish salt, or run your boat hard in freshwater.
• Xducer ID technology — automatic transducer recognition — plug it in and your fishfinder recognizes the transducer specs and settings without manual configuration.
