How to troubleshoot a 'No depth reading / lost bottom lock' on Raymarine Marine Equipment?
- Llucas79Aug 18, 2025
If your Raymarine Marine Equipment is not showing a depth reading or has lost bottom lock, verify that the transducer has been installed according to its instructions. If the transducer angle is too great, adjust it, as the beam may be missing the bottom. If the transducer has a kick-up mechanism, ensure it hasn't been activated by hitting an object. Check the power supply voltage as close to the unit as possible under load. Inspect the transducer for damage and ensure it is free from debris or fouling.
