Airmar B75H Transducer CHIRP Thru Hull 20° Tilt

Overview

Built for serious anglers and charter captains running boats up to 25 feet who need precision target separation and bottom definition in one compact installation. If you're fishing competitively or professionally and rely on seeing the difference between individual baitfish and structure, this is the transducer that delivers it.

The B75H is a CHIRP thru-hull transducer that gives you 80 kHz of total bandwidth in a single installation—no need to stack multiple transducers. It delivers 5 to 10 times greater detail and resolution than conventional units, letting you distinguish game fish from baitfish and read structure with clarity that changes how you fish. With bottom detection to 10,000 feet and built-in water temperature sensing, this is built for anglers who demand real answers, not guessing.

Key Features

• CHIRP Sonar (130–210 kHz) — transmits across a 80 kHz bandwidth in one transducer — covers the popular 200 kHz fishing frequency plus everything else, eliminating the need for a dual-frequency setup.
• Adaptive Beamwidth (15° to 9°) — automatically narrows as frequency increases — gives you tight target definition on structure and suspended fish without losing coverage area.
• 3,000-Meter Depth Capability (10,000 feet) — whether you're working deep offshore or shallow flats, this transducer reaches further than most recreational hulls will ever need.
• Fast-Response Water Temperature Sensor — accurate, live temperature data built into the transducer — critical for understanding seasonal patterns and fish location.
• 20° Tilt Installation — angles the transducer for optimal cone placement on planes with high deadrise — ensures proper sonar coverage when your hull geometry matters.
• 600W Power — enough output to deliver clean, readable returns in challenging conditions and at extreme depths.
• Bronze Housing — corrosion-resistant material rated for saltwater and freshwater — built to last in harsh marine environments.

Specs & What's Included

Designed for fiberglass and wood hulls up to 25 feet. This transducer requires a compatible cable assembly sold separately (Mix and Match Cable). Your sounder head must support CHIRP functionality to take full advantage of the bandwidth and resolution this unit delivers. Not sure if this works with your setup?
