The Garmin GT12M-THF (0-degree Tilt) is a robust 350-watt thru-hull transducer designed specifically for midsize fishing and cruising boats. It features a flush-mount bronze housing that minimizes drag and water turbulence, ensuring high-speed sonar performance and a clean hull profile.

This model utilizes Mid-band CHIRP technology, which provides a balanced frequency range to deliver excellent target separation and clear fish arches in both shallow and moderately deep waters.

Key Features

• Mid-band CHIRP (85–165 kHz): Delivers high-definition sonar images, making it easier to distinguish between baitfish and larger predators.

• 0-Degree Tilt: Engineered for boat hulls with a deadrise angle between 0° and 7°, keeping the sonar beam pointed straight down without the need for a bulky fairing block.

• Bronze Flush-Mount Design: The low-profile housing sits nearly level with the hull for minimum drag and is compatible with fiberglass, wood, and composite hulls.

• Auto-ID Technology: Enables seamless plug-and-play operation by automatically sending transducer type and configuration data to your compatible Garmin chartplotter.

• RapidReturn™ Compatible: Optimized for faster sonar update rates, providing more immediate feedback on your screen.
