Garmin 010-10194-21 P319 Depth/Temp Thru Hull 8-Pin

The Garmin 010-10194-21 P319 Depth/Temp Thru Hull 8-Pin transducer is a proven workhorse for anglers and boaters who demand reliable sonar performance in freshwater and coastal applications. This thru-hull mount transducer delivers real-time depth and water temperature data directly to your Garmin fishfinder, giving you the precise information needed to locate structure, identify thermal layers, and make informed decisions on the water. Whether you're targeting trophy bass in a reservoir or exploring new territory offshore, accurate depth and temperature readings are foundational to fishing success and navigation safety.

Built for permanent installation, the Garmin P319 features an 8-pin connector interface compatible with established Garmin fishfinder architectures, and operates across dual frequencies—50 kHz for wider beam coverage and bottom definition, and 200 kHz for fine detail and shallow-water clarity. The plastic thru-hull housing is designed for mounting on hulls with 0–7° deadrise angle, ensuring optimal transducer face alignment and signal transmission across a wide range of boat designs. This dual-frequency capability allows you to switch between coverage patterns depending on depth, speed, and target species, making it a flexible solution for anglers who fish variable water conditions throughout the season.

Ideal for owners upgrading or replacing factory transducers, the Garmin 010-10194-21 integrates seamlessly with compatible Garmin sonar units and modern chartplotters. Professional installation through the hull requires careful drilling and sealing to prevent water intrusion, making professional service advisable for those without marine electronics experience. Weighing 1.87 lbs and engineered for durability in saltwater and freshwater environments, this transducer delivers years of dependable performance when properly mounted and maintained—essential equipment for serious anglers who rely on sonar to stay ahead of the bite.
