Garmin M265LH Plastic In-Hull Mount Transducer w/Depth - 12-Pin

The Garmin M265LH Plastic In-Hull Mount Transducer w/Depth - 12-Pin is the workhorse sounder head for serious anglers and boaters who demand reliable depth and fish-finding performance without breaking the bank. This in-hull transducer mounts flush against your hull interior, making it ideal for boats where drilling through the hull isn't practical or where you want a cleaner installation. Whether you're targeting structure on a freshwater lake or navigating coastal flats, this transducer delivers consistent sonar data to keep you fishing smarter and safer on the water.

Built with a durable plastic housing, the M265LH transducer is engineered to withstand the rigors of regular boating while providing clear depth readings and fish-arch detection through Garmin's proven sonar technology. The 12-pin connector integrates seamlessly with compatible Garmin chartplotters and fish finders, delivering stable signal transmission even in challenging water conditions. In-hull mounting means the transducer sits inside your hull, communicating through the fiberglass or composite material—a design that works exceptionally well in freshwater and calm conditions where hull thickness doesn't significantly degrade sonar clarity. The compact form factor (11 x 8 x 12 inches) makes installation straightforward without requiring major modifications to your boat's structure.

This transducer is purpose-built for boaters upgrading existing Garmin systems or installing a primary sonar package on recreational and fishing vessels. The 12-pin connection ensures compatibility with mid-range to premium Garmin fish finders and GPS chartplotters from the last two decades, making it a smart retrofit choice for boat owners with established Garmin electronics. Installation requires mounting the transducer securely to the inside of your hull using the provided brackets, ensuring full contact with the hull surface for optimal signal transmission. At 12.3 pounds, it's substantial enough to resist vibration and movement while remaining manageable for DIY installation. Anglers who've run plastic in-hull transducers know they deliver genuine performance at a price point that makes upgrading your sonar suite accessible—a true value product for the serious boater.
