*Achieved maximum height is dependent on several variables, including tilt of the sensor head, flatness of the bottom, hardness of the bottom, vegetation cover on the bottom, and salinity. On a hard-bottom body of water such as Lake Superior, we regularly achieve 40+ meters. On a muck-bottom lake such as Lake Minnetonka, we sometimes struggle to get 20 meters. Hard-packed sand bottoms tend to be somewhere in between those extremes.
