Hopefully not our last geocaching day

Last weekend before the big rain we made a last tour with our GPS.. It has some problems to run correctly and no it is on the way to get repaired. I hope we'll get it back soon.

The little geocaching tour we made near Hastenbeck this time. All caches weren't very hard to find. But the last one was a bit more difficult. You had to move a little ball through a maze to get the logbook. That was a nice idea.
I hope this wasn't our last cache. If you go geocaching what kind of GPS do you use? Ours still had a guarantee, but I don't know if we'll get it back.
