Thanks Pepop ... I'll keep that in mind !!

I've had little chance to even use it, over the last couple of months ... and even when I did, which was on a couple of night trips, I was in a situation where the GPS/chart wasn't necessary.

I am, however, collecting some waypoints from friends, and intend to punch them in manually ... when the time comes that I'm on that particular lake. I haven't really had to use the GPS/chartplotter function very much, since I installed the unit ... mainly because I've fished lakes & places on those lakes that I'm very familiar with, having fished them for decades.

In the meantime, I have noticed that my "tracks" from previous trips have been recorded. But, while those tracks are pretty much useless to me now, I can see where they'd come in handy ... say like when on a several day trip, and I want to review each day's movement/search pattern & areas covered.

One thing that cracks me up about the internal/base map ... is that it has 7ft, 17ft, & 27ft contour lines on a 3000 acre lake that I fish, but on a 8000 acre lake I fish ... there are no contour lines in the map. Well, none that I've noticed, anyway. It may just be that I haven't zoomed in the chart (or used the chart) enough to bring them on screen. I'll have to check that out, next time I'm on the 8000 acre lake.
