The Airmar B75M Bronze Chirp Thru Hull 20° Tilt - 600W is a rugged, broadband through-hull transducer built for commercial, charter, and tournament anglers who demand precise depth and reliable target discrimination. It’s designed for fiberglass or wood boats up to 8 m (25’).
-
Through-hull bronze housing: Durable bronze construction designed for harsh marine environments and long-term reliability.
-
20° tilt design: Optimized for accurate bottom tracking and improved target discrimination across varied conditions.
-
600W power: High-power performance for strong, consistent CHIRP signals.
-
CHIRP bandwidth: Medium CHIRP coverage from 80 kHz to 130 kHz with beamwidth transitioning from 24° to 16°.
-
Additional bandwidth: Extra 50 kHz of bandwidth from a single transducer, including 88 kHz and 107 kHz within the range.
-
Exclusive Xducer ID technology: Easy, reliable identification by compatible sonars.
-
Hull compatibility: Suitable for fiberglass or wood hulls up to 8 m (25’).
-

-
Depth and water-temperature sensor: Depth measurement and fast-response water-temperature sensor included.
-
Bottom detection and detail: CHIRP delivers up to 3,000 m (10,000’) of bottom detection with 5–10x higher detail for distinguishing baitfish, game fish, and structures.
-
Single transducer convenience: A single transducer streamlines installation and minimizes downtime.
With its bronze through-hull design and CHIRP capabilities, the B75M provides reliable, high-detail sonar for depth, structure, and fish detection. The 20° tilt enhances bottom tracking in varied seas, while the 80–130 kHz bandwidth covers key fishing frequencies—including 88 and 107 kHz—giving you clearer targets, bait, and underwater features. The integrated depth and fast-response temperature sensor means you get temperature data alongside depth, aiding in fish behavior interpretation. Durable bronze housing, compatibility with fiberglass or wood hulls up to 8 m (25’) and the Xducer ID technology simplify installation and sonar compatibility across vessels.
