Depth Reading error (i70 & a95 MFD)

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Rick,

Should the vessel be in water have a depth of at least 3' below the transdsucer and the depth of the water an heel of the vessel not exceed the operational range of the depht sounder, then the sounder should report depth correctly. The only related configuration settings are configuration of the i70 as the Depth Data Master, depth/keel offset, and units. Should these settings be properly configured and the vessel be in water of the depths stated in this response, then there may be a fault with either the transducer or iTC-5. Unfortunately, there is no resistance or other end user based test which may be performed other than to test the iTC-5 with another instrument depth transducer which was suspended over the side of the hull. Should the problem abate with the test transducer, then the currently installed transducer would need to be replaced. Alternatively, the iTC-5 may be sent to Raymarine’s Product Repair Center to be bench tested/serviced.
