Adjusting the transducer If the sounder image shows interference lines on the screen when moving, which worsen with speed, it may be possible to eliminate these by adjusting the transducer's angle. ¼¼ Note: A transducer that is tilted too far in either direction will not perform well, missing targets, and/or losing the bottom at speed. If performance does not improve with tilting, try adjusting the height of the transducer relative to the transom of the boat. If the transducer is too high it may be seeing cavitation caused by the trailing edge of the transom. 16 | Display Installation | HDS Gen2 Touch Installation Manual
