Airmar B75H Transducer CHIRP Thru Hull 12° 600W

Overview

Who This Is For: Tournament anglers, charter captains, and serious recreational fishermen who need exceptional target separation and bottom detail in a single thru-hull installation. If you're running a modest to mid-size boat and want CHIRP performance without the complexity of a multi-transducer setup, this is your transducer.

Product Summary: The B75H is a bronze thru-hull CHIRP transducer that delivers broadband sonar capability with exceptional resolution down to 10,000 feet. One installation gives you up to 80 kHz of total bandwidth — meaning you'll distinguish individual baitfish, gamefish, and structure details with clarity that makes the difference between a productive day and a wasted one. It's the engineering advantage when you need precise bottom detection and fish marking in a compact package.

Key Features

• CHIRP Broadband Sonar — transmits across a continuous frequency range rather than a single frequency — you get 5 to 10 times greater detail and resolution, letting you separate individual fish from structure and distinguish species at a glance.
• 80 kHz Total Bandwidth — one transducer covers the full spectrum — eliminates the need for dual transducers and simplifies your install while giving you the performance of a multi-frequency system.
• 12° Cone Angle — narrow beam focuses sonar energy directly below your boat — ideal for deep-water work and precise bottom definition when you're targeting specific structure or suspended fish.
• 600W Power Output — strong transmission cuts through noise and clutter in saltwater and heavy-use environments — you'll maintain crystal-clear returns even in challenging conditions.
• Bottom Detection to 10,000 Feet — reaches depths most recreational anglers will never need, but gives you the margin to fish deep structure confidently.
• Bronze Thru-Hull Housing — durable and corrosion-resistant — engineered for saltwater exposure and built to last without degradation.

Specs & What's Included

Compatibility: This transducer requires a Mix & Match Cable — meaning you'll need to source or purchase the correct cable connector for your specific fishfinder unit. Before ordering, confirm your sounder's transducer connector type and cable requirements. Not sure if this works with your setup? Call or text us at (833) 831-4077 — we'll tell you straight.
