Garmin P319 Plastic Thru-Hull Depth/Temp - 8 Pin

The Garmin P319 Plastic Thru-Hull Depth/Temp – 8 Pin is a reliable transducer engineered for anglers and boaters who demand accurate sonar readings without the complexity of metal hull penetration. This plastic thru-hull design delivers dual-function capability, providing real-time water depth and temperature data directly to your Garmin chartplotter or fishfinder. Whether you're targeting structure in freshwater lakes or running coastal waters, this transducer bridges the gap between budget-conscious installation and professional-grade performance.

Built with a durable plastic housing, the P319 resists corrosion and galvanic damage—a critical advantage over metal alternatives in saltwater environments. The 8-pin connector architecture ensures seamless integration with compatible Garmin systems, transmitting both depth and temperature signals through a single, streamlined installation. The transducer's compact profile minimizes drag and noise interference, allowing you to maintain boat speed and fuel efficiency while gathering the bathymetric and thermal data that separate productive fishing zones from dead water.

This transducer suits both recreational anglers upgrading legacy systems and boaters installing new sonar networks on modest budgets. Installation requires a thru-hull mounting location, ideally positioned away from engine intake or discharge zones to avoid thermal and acoustic distortion. The P319 is fully compatible with Garmin's 8-pin sonar ecosystems, including older 4000 and 5000 series chartplotters as well as modern integrated systems, making it an excellent retrofit option for boats equipped with legacy Garmin hardware.
