That's the reason I use a hand held GPS unit

I prefer to use a hand held unit which has way more going for it in terms of capability than the GPS function in the CTX 3030. The Delorme PN series allows you to download topo maps, aerial maps and detailed land use maps directly to the unit and see where you are on the color screen. You can create find points and when you get home, it interfaces with Topo USA which is way more detailed than the maps you get with XChange2. The other nice thing is I can hang it around my neck regardless of what detector I might be using and still record the data. Being able to create routes to follow at home to bypass ravines, swamps, or other areas is another plus . . .
