Blue Robotics released the Ping360 in September 2019, a mechanical scanning sonar for navigation and imaging. It has a 50 meter range, 300 meter depth rating, and an open-source software interface that makes it a very capable tool for ROV navigation and underwater acoustic imaging.

The Ping sonar, released in January 2019, is a single-beam echosounder that measures distances up to 30 meters underwater, with a 30 degree beam width, and 300 meter depth rating.
