i have selected return to vessel. The only waypoint I saved was the mouth of Harrods Creek off the Ohio near Louisville, as it was not on the basemap. That surprised me, as this is a major creek-about 30-40 ft across. Followed the creek back a mile or so, then returned because it was getting dark. I was unable to stay right on the pink route line because It would have run me ashore a couple of times, but mostly it stayed in the creek at least. Next time I'll experiment a little more with the gps. I also wanted to drop and mark (with boeys) some objects, than pass over and beside them to see just when and where in relation to the boat they show up on the unit. Cant wait to get on the water again, and I'll be sure to save a shot of my nav. settings Pappy, and lots of shots of what i see. I'am still amazed at the detail, it was more like looking at a moving landscape mural than a fish finder! sorry about the spelling fellas, it was never my strongpoint, and the spell check isn't working.
