The GPS 72 is a good basic gps unit. A friend has a new one. A couple of days ago he was telling me that he is sorry that he did not spend the extra money for a Garmin Legend or a GPSMAP76.
The fault is mine, because I bought a Legend a few months ago, uploaded maps from Garmin Map Source USA Topo into it for local area. He could see this winter when we were geocaching how neat it was to have the topo map on board. I topped it off the other day when I showed him a map of waypoints(fish) that I had marked after finding them with my fishfinder on a local lake. I also told him about returning to the lake using those waypoints to pickup fish on a following day. Yes he could have created a waypoint on the the GPS 72 for the fish. I had downloaded the waypoints on the lake to my computer, and then printed the map of the lake with waypoints on it.
But with the topo map loaded in my gps I can follow along a submerged ridge without hanging up my downriggers.
The bottom line is what are your expectations. At one time I was proud to carry a Siva Ranger Compass. Now I carry a compass and a gps. I would have been happy with a GPS 72 until I found the mapping units.
