Where the H element trades some of the M element's extra depth penetration for finer target separation and sharper bottom detail -- better suited to shallower-to-moderate-depth fishing where picking individual fish out from structure matters more than chasing maximum depth -- this specific unit is Airmar's 12-degree tilted-element version, built with a fixed internal tilt to compensate for a hull deadrise of roughly 12 degrees at the mounting location, so the beam still points straight down at the seabed rather than off to one side on an angled hull. It shares the family's 1kW power rating, an 8-pin connector for direct wiring into a compatible Garmin sounder module or MFD sonar input, and CHIRP broadband transmission for depth sounding and fish/bottom imaging. Sold as the transducer and mounting hardware only, for a fixed thru-hull installation.
