Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The Garmin B75M is a bronze thru-hull transducer that brings medium-frequency CHIRP performance to a compatible Garmin sonar system. The flush-mounted housing protrudes less than a quarter of an inch outside the hull and can sit on trailer rollers or bunks without damage, while the tilted element inside aims the sound beam vertically and removes the need for a fairing block. Built-in depth and water-temperature sensing comes as standard.
This 20° tilt model is matched to hull deadrise angles of 16-24° and gives a versatile balance of target separation and depth penetration. An excellent choice for fibreglass and wood hulls, it connects to CHIRP-capable Garmin chartplotters, combos and sonar modules. The transducer is supplied with installation instructions, which should be followed carefully to avoid damaging your boat.
