Got back from Bassmaster University a couple weeks ago and meant to post this msg but almost forgot. One of the Pro's giving the sessions was Don Iovino. He is sponsered by Lowrance and his sessions involved finesse fishing and sonar electronics. I think deep water fishing was his thing. Anyways, the info I got regarded the transducer cable installation on the trolling motor shaft. What I was told was that if you use tye wraps (or anything else) that tightens up against the insulation enought to leave an impression is toooooo much. you've damaged your transducer calbe and affected its sensitivity. I think the jist of it was that the shield inside the cable gets too close to the signal wire or touches the drain wire. His advice is to install with electrical tape or something else that would not smash the outer insulator (the black outer covering of the cable). I found some clips at Academy Sporting Goods that look like they would work out. Thought I would pass this along. We pay hundreds of dollars for all those pixels and then screw up our cables with tye wraps. He also said that you really couldn't tell if the unit was affected or not, but, just go by the insulator, if it is put on tight enough to leave an impression, it is too tight and you need a new cable. Thought I would pass it on.
