Morning Guys, another question that you may know the answer. I was using my 899 ci HD Si to jig lake trout the other night. It was tracking my jig ok , but once I go over 131 feet of water it pretty much cuts off. It flickers to 10 feet of water on screen or just goes blank. I have the max depth on auto, is there some other setting I should have it on cause its not making sense why it would do this. Thanks
