Integrate xyo devices into already existing geocaches worldwide that when found reward and log the find. It would replace the unreliable technology, archive the log and provide a security/emergency location for hikers/explorers. This would also be a great community to seek out to expand the network as a pastime.
I like this idea
One thing jumps to mind immediately is ‘Size’…
Not all geocaches are large enough to accommodate a sentinel but your idea definitely has interesting possibilities. Might I suggest an ‘XY4 Trackable Bug’ ?
This is maybe one way we could introduce the XYO network to the Geocache community and it might spark some new features to be developed??
