edwin Posted September 23, 2014 Posted September 23, 2014 I had a similar issue, was the same fix as Z22 and griz mentioned. My BassCat had Y cable with a puck epoxied to the hull for depth, second transducer on the jackplate for side and down imaging. I monkey'd around with it and it was definitely the epoxied transducer in the bilge causing the issue. Removed the Y cable and ran the jackplate mounted one direct to the 997 and all good. "Advantages are taken, not handed out"

WettinLine Posted September 24, 2014 Posted September 24, 2014 Have you ran the new firmware updates?
inshore Posted September 24, 2014 Posted September 24, 2014 alex you can set these to record down to a certain depth or bottom lock check in your advanced settings and see if this could be your problem.
