Our Death Valley trip was cancelled due to the government shutdown, but we changed our Geocaching plans and found six fun benchmarks that hadn't been found in years. How could we tell? They were buried under an inch or two of dirt and moss. Cachly performed wonderfully. I sent my .gpx file to Tung8 and while I drove, he read the description and I snuck a peak at the map and where we were at. When we got close enough, we focused on the descriptions.
The only thing is we saved the benchmarks as finds when we were done, but those won't upload to Geocaching for probably good reason and even the .txt file screws it all up. Which isn't a huge deal because I usually know what benchmarks I found by looking at my photos on my phone since I take photos of each one I find.
Cachly is certainly a great option for those of you wanting to do paperless benchmarking where you don't have reception. If we can get it to do live benchmarking support, that would be awesome!
