I often do bike tours and beforehand put a pocket query on my GPS (in which certain cache types as e.g. Event Caches are excluded)
This query allows me easily to realise when I come along a cache.
With regard to mysteries (aka puzzle caches) it would be absolutely perfect, if there was a possibility to create a pocket query which includes solved caches only.
This could be realised by an additional checkbox to be filled by user or by the fact that coordinates have been updated in GC.com.
This would allow me to only show the solved mysteries while biking around, but ignore the unsolved for this point of time. Right now, I always have to take my smartphone, go online and check whether the coordinates on my GPS device are already solved ones or still the original fictional ones.
I did not find this issue being discussed here in this forum, though I cannot imagine I would be the only one who would appreciate this!?
