WebThis page details the setup of a low-cost analog underwater sonar (aka “fish finder”) and a digitizer to convert the analog readings into NMEA 0183 which can be read by ardupilot. This setup allows measuring the depth of the water below a boat. The sensor described has a maximum claimed a range of 300m and a relatively wide beam of 22deg. WebIn fact, utility tracing can be completed for just about any underground utilities. Typically, our underground utility detection surveys are completed to The Survey Association Level 4 or BSI PAS128 specifications.
