I have a new BassTracker that I just bought from Bass Pro for crappie fishing. Got rid of my big boat for something a little smaller that I can handle by myself easily. Kids gone so it's just me now. Thanks for the advise on the 12" screen. Was looking at it very hard and will give it another look. I will get the ipilot version as I'll want to upg the trolling motor. Looks like it's gonna cost me 3K+ just for the 360 & the 12" Helix. Anyone using the transom mounted 360 and do you mentally compute the length of your boat when you're judging distances?
