Raymarine a78 MFD w/CPT 100 CHIRP transom mount transducer. System has performed flawlessly for a couple of years. Recently started losing the bottom at somewhere between 60-100'. Fortunately works fine in shallow waters for anchoring or near shore maneuvering.
Any ideas on what to check? The vessel is 30' Bayliner with outdrive. No changes have been made to the boat or systems since installation, and all did work well beforehand. The vessel is in the water and I have not been able to check if the transducer "kicked up" for some reason, but seems like it would completely stop functioning if that was the case.
Thanks in advance for any suggestions....
