Anyone else have a 788 series in their console and have the gauge go from 4ft to 92ft back to 7ft back up to 67ft in a matter of seconds? This numbers are just examples of course but mine will go as low as 6 inches to as high as 92ft and everywhere in between in a matter of seconds. Im never in more than 4-18ft of water usually. I didnt know if it was a loose transducer or if a setting was off on the depth finder. I have it set on shallow fresh water but it can never give me a CONSISTENT reading. Its already caused me to come extremely close to bottoming out on some rocks while thinking I was in deeper water. Its on a new Margay. I have zero experience with depth finders so I wasnt sure what is normal and what isnt. I cant see how this is but you never know. Its only when Im driving it. Sitting still its consistent with the trolling motor depth finder. Thanks
