Garmin 010-12380-20 M265LH Plastic In Hull Transducer

The Garmin 010-12380-20 M265LH Plastic In Hull Transducer is purpose-built for anglers and boat operators who demand reliable sonar performance without the expense of through-hull installation. Whether you're fishing shallow lakes, coastal bays, or inland reservoirs, this in-hull transducer delivers consistent bottom-tracking and fish-finding capability by mounting directly inside your boat's hull—eliminating the need for drilling or structural modifications. Boaters appreciate the simplicity: no marine sealants, no potential leaks, and no compromised hull integrity.

The M265LH uses proven plastic construction that transfers acoustic signals effectively through most fiberglass and aluminum hulls while remaining lightweight at 12.4 pounds, making it easy to position and secure during installation. This transducer operates on proven Garmin sonar technology, providing crisp returns on your chartplotter or fishfinder display and enabling depth readings, thermocline detection, and underwater structure identification. The plastic housing resists corrosion in saltwater environments and eliminates the maintenance concerns associated with metal transducers, making it an ideal choice for seasonal and year-round boaters alike.

Experienced anglers choose the Garmin 010-12380-20 M265LH for retrofit installations, backup sonar systems, or situations where through-hull transducers are impractical. Installation works best when mounted in direct contact with hull bottom surfaces and submerged in water; compatibility with Garmin chartplotters and fishfinders ensures seamless integration into existing systems. This transducer is particularly valued by tournament anglers, coastal guides, and recreational boaters who need reliable sonar at a fraction of professional through-hull costs.
