Common Concerns Answered
Will the 20-degree tilt work on my high deadrise hull?
The Garmin GT15M-THF is designed for deadrise angles from 16 to 24 degrees. For very high deadrise hulls exceeding this range, a fairing block may be required to achieve optimal performance and proper angling.
Is installation complex?
Installation requires drilling through the hull, rated at a 3/5 difficulty. While the flush-mount design simplifies alignment and reduces drag, precise sealing and placement are critical. Professional installation is recommended for boaters unfamiliar with hull penetrations to ensure watertight integrity and optimal sonar readings.
Can I get the best performance without professional installation?
While DIY installation is possible, users report that optimal performance hinges on proper installation alignment. Ensuring the transducer is perfectly oriented within the hull's flow line is crucial for accurate readings and minimal drag. Deviations can lead to performance degradation.
