ST60 depth trouble

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum SaltyGirl,

As long as the vessel is operating within the minimum and maximum (the latter will be be reduced by heeling) depth range supported by the depth instrument then the fault may be rooted in either the depth instrument display or its transducer. Unfortunately, it is not possible to perform simple multi-meter based tests to fault isolate the problem. The problem would typically be isolated in the field by testing the instrument display with another compatible instrument depth transducer which has been suspended over the side of the hull while the vessel is dockside or at anchor. Should the problem be determined to be rooted in the ST60 Depth instrument, then the ST60 Depth instrument would need to be replaced with an i50 Depth/Tridata instrument or iTC-5 (would make the i70 become the system's depth Master).
