Description
The GARMIN GT12M-THF Bronze 0° Tilt CHIRP Thru-Hull Transducer is a bronze medium-frequency CHIRP thru-hull transducer with a 0° tilted element. It operates across approximately 85–165 kHz and is intended to keep the sonar beam closer to vertical on hulls with the appropriate deadrise.
Main Features
- Bronze thru-hull housing with 0° tilted element
- Medium-frequency CHIRP approximately 85–165 kHz
- 350 W sonar power rating
- Integrated depth and water-temperature sensing
- 15 m attached cable for permanent through-hull installation
Tilt selection
The 0° version is generally suited to hull deadrise around 0–7°.
Sonar performance
Garmin specifies a maximum depth in favorable conditions of about 1,200 ft freshwater / 800 ft saltwater. Real-world depth depends on water conditions, speed, installation quality and the connected sounder.
Hull compatibility
The bronze housing is intended for fiberglass/wood hulls; not for aluminum or steel hulls. Follow Garmin’s isolation and sealant instructions; mixing incompatible metals can create corrosion problems.
Installation
This is a permanent through-hull sensor. Confirm deadrise, internal clearance, hull construction and access for the retaining hardware before drilling the hull.
