Heavy Duty Transducer Bracket - Bronze Through Hull Conversion - Airmar (B275, B265, B260, B285)

Strength. Performance. Simplicity.

Upgrade your transducer setup with the PROTEK Heavy Duty Transducer Bracket — purpose-built for Airmar 1kW Bronze dual-frequency through-hull transducers like the B275, B265, B260 and B285.

Our bracket converts these through-hull units to a transom-mount setup, making installation and performance smoother and more reliable. The best of both worlds — the sensitivity of a 1kW bronze transducer, without the through-hull install.

Precise adjustability

A full range of transom angle adjustment from 0° to 25° lets you fine-tune the transducer position with ease — no wedges, no shims, no complicated setup.

Built tough

4mm thick 316-grade marine stainless steel construction reduces vibration and provides a stable mount, even in tough offshore conditions. The bolted transom plate replaces the need for long pins, keeping the bracket securely in place and eliminating unwanted movement.

Designed for easy retrofitting

The bracket uses the same mounting holes as your OEM bracket — no new drilling required. The slotted transducer plate also makes tight-space installations easier, without needing to remove cables.

Built for the serious angler

Every detail is designed with offshore performance in mind. A securely mounted transducer reads cleaner, performs better at speed, and lasts longer — giving you the confidence to go further and fish longer.
