Garmin Quarter Turn Locking Collar

The Garmin Quarter Turn Locking Collar is a precision mounting accessory designed for securely fastening Garmin transducers and sensors to your vessel's thru-hull fittings or bracket assemblies. This product is essential for boaters and anglers who rely on stable sonar performance and accurate readings while on the water.

Featuring a quarter-turn cam-lock mechanism, this locking collar allows for tool-free installation and removal, eliminating the need for wrenches or hex keys. Its positive-lock engagement system is engineered to resist loosening from engine vibration and boat wake shock, ensuring reliable performance in both saltwater and freshwater environments.

Ideal for those using Garmin CHIRP transducers, trolling motor sensors, or thru-hull sonar systems, this accessory integrates seamlessly with standard Garmin transducer mounts. Whether you're navigating in a center console, cabin cruiser, or aluminum hull, the quarter-turn collar provides the stability needed for accurate fish-finding and depth readings.
