Ping Sonar Altimeter and Echosounder
The Ping sonar is a single beam echosounder that measures distances up to 50 meters underwater. This sensor enables a new control mode called "Auto-Altitude", which allows you to keep a constant distance to the seabed even if the water depth is changing while you move around.

Technical Specifications
Ping Sonar Altimeter and Echosounder
The Ping sonar is using a wide-beam pulse (30 degrees) that makes it robust against an uneven sea bottom with obstacles sticking up. If you have it forward facing, it will also help you to find large objects such as a quayside wall or a shipwreck, which is particularly useful for navigation. The minimum distance it can measure is 0.5 meters, so if you go closer than this, you cannot trust the readings.
