wow thank you Gerald .It hasn't worked right since I bought the boat from a local dealer in Columbia. it does work on demo mode. I have one on my tm and in the console.
For the longest I thought it was all me not knowing how to use one. I watched all the videos on how to read a fishfinder and have never seen arches or anything on mine. The depth wasn't even working right as I catfish a lot too and know how deep a lot of my spots are.
I wonder if I should call the dealer and even they'd even help me. I bought the boat, a Ranger RT188, last October.

Thank you very much for taking the time to help.
