Hi There,
this is new to me also, I've had to visit a site 3 times before I found the cache I was looking for. I used my Garmin Ique M3 which is my mobile GPS. It has selectable icons for the map locations. So for the cache I download I use a Closed Treasure Chest and when found I change it to an Open Treasure Chest. This way I can always keep track of my "conquest's" in any given area at a glance...
