PanMan that to me is the best way to find you spot regardless of what GPS you are using. I have 2 Garmin handhelds, GPS 72 (my 1st) and a GPSMap 76CX up front on a movable mount that I use as you say to get close and then use the TM and DF to get on top of your spot. I have the 72 on the pointer page and the 76 on the map page altho the map page for my main small lake is way off, don't have any thing but the base map and a couple of my best spots show up on land. The marker really comes in handy when the wind is blowing as I never anchor.
