*Achieved maximum height is dependent on several variables, including tilt of the sensor head, flatness of the target plane, hardness of the target plane, vegetation cover on the target plane, and salinity. On a hard-bottom body of water such as Minnesota's Lake Superior, we regularly achieve 50 meters. On a muck-bottom lake such as Minnesota's Lake Minnetonka, we sometimes struggle to get 30 meters.
**Assuming the sensor head is oriented parallel to the target surface.
***Maximum speed may vary with height above target plane.
****The recommended interface is Ethernet. Serial interface is possible with a user-supplied custom cable. Some features, such as mavlink2rest communication, are lost when using serial.
