After returning a horizontal line on the screen at the 10′ (3.05m) depth reading, the unit was replaced, but the problem persisted. Scott Allen, the yacht’s owner, EHM’s staff, and Furuno’s technicians were flummoxed. “The best hypothesis is the location of the Triducer relative to the keel—a resonance issue of some sort,” Allen reported.
