The Garmin GT17M-THF (0-degree Tilt) is a professional-grade, flush-mounted thru-hull transducer designed for larger fishing and cruising vessels. With 1 kW of power and Mid-band CHIRP technology, it is optimized to provide high-definition sonar returns while minimizing hull drag.

Key Features

• Mid-band CHIRP Traditional Sonar: Utilizes a frequency range of 80–165 kHz to clearly define fish targets, underwater structure, and bottom depth.

• 0-Degree Tilted Element: Specifically engineered for hulls with a deadrise angle between 0° and 7°, ensuring the sonar beam is oriented vertically for accurate readings.

• Flush-Mount Design: The stainless steel housing sits nearly level with the boat’s hull, reducing drag and water turbulence which helps maintain clear sonar signals at higher speeds.

• RapidReturn™ Technology: Compatible with Garmin’s faster sonar update rates, providing more immediate visual feedback of activity beneath the vessel.

• Auto-ID Technology: Features a plug-and-play identification system that allows compatible Garmin chartplotters to automatically configure the sonar settings for this specific unit.

• Fast-Response Temperature: Includes a built-in sensor for real-time water temperature monitoring.

• Broad Compatibility: The durable stainless steel construction is suitable for various hull materials, including fiberglass, composite, steel, aluminum, and wood.
