One thing I have noticed with my ghost is that when I hit spot lock it seems to want to back up more than it should (5-10 feet). It seems to hold well once it gets there, but this is a little annoying. I thought initially it was because of the wind and that I had moved more than what I thought each time, but it seems to do the same thing on calmer days too. I did the calibrations and also tried moving my gps puck around (per lowrance feedback) but it hasn't seemed to matter. Just wanted to get some input from others out there on their experience and thoughts.
