[edit] Image and ribbon

My spontaneous idea for a picture would be a person stumbling over a tupperware-styled box. I'm not really good at drawing so maybe someone else volunteers? Or has another idea, of course...

Another thought: Given that the chances for the honorable mention are pretty high (I could have got one from four of my six visited hashes so far) but near-zero for the real thing, I think the ribbon should include support for the honorable mention.

Sounds like a job for me. It's on my to-do list now. --Ilpadre 19:31, 28 November 2008 (UTC)
Thanks, that turned out well :) --Ekorren 23:02, 7 December 2008 (UTC)

[edit] Related stash hunts

This is more a theoretical thought as here in germany this probably won't ever happen. There are places in other countries where it may well apply, though.

What about if someone finds a letterbox, ciste, or whatever other box there may be out in the wild?

  • Cistes are mostly the same as geocaches, but they don't use coordinates and GPS but a description of the place.
  • Same applies to letterboxes with the additional feature that letterboxers must have a personal stamp with which they sign the logbook, and keep an own logbook to collect imprints from a stamp in the box.

Cistes are (under this name) mostly known in France, letterboxes all over the world with the roots in the UK. Since geocaching defines itself over the use of GPS and coordinates, both of them do not qualify as geocaches.

Myself, I'm not really sure about counting. Basically, these are the same as geocaches. But the achievement is about a hash collision, i.e. double usage of the same value (coordinates), and the other stash hunts don't use the coordinates themselves. Still, they may lead to the same place, so the collision is there on the physical plane. --Ekorren 23:02, 7 December 2008 (UTC)

[edit] Winning

This was a win, not just an honourable mention. Thepiguy spotted the cache hiding place while standing at the geohash. (Robyn)

Ok, sorry. I now see I misread the achievement page -- I thought the cache had to lie within the circle of uncertainty, not just within sight! Oops! -- Benjw 12:46, 7 March 2009 (UTC)

I didn't think it would ever happen. The coordinates were only different by one second. I thought when he said there as a cache it was just in the same park. - 17:54, 7 March 2009 (UTC)

[edit] Define it more specifically

Making the achievement "within the circle of uncertainty of your GPS" is too vague in my opinion. It simply encourages you not to let your GPS lock on. Since both geohash and geocache locations are verifiable with great precision online, I'd like to redefine the requirement to be "within 100m of the the hash point". --Davidc 21:20, 13 August 2009 (UTC)
