Inaccurate Coordinates & Missing Cache first off aside from what the others do with the manual Garmin averaging, I prefer to let my little Magellan sit for atleast a minute then let the units self averaging do its thing for another minute, this has been the norm for our over 25 caches I have only had to adjust the coords once, but that was due to interference.... besides if the coords took you to zero everytime what fun would the 04/04/04 and Graldrichs caches be? I agree with the 15 foot radius, that is pretty much the GPS norm. as the Event cache and the ZERO experiment goes even the same units will be off a little.. as far as cache plundering goes... someone was curious to what was going on as they spotted a cacher caching. this someone was greedy someone found it by mistake and was greedy.. ----- Original Message ----- From: "SquishyGecko" To: Sent: Friday, April 23, 2004 8:35 AM Subject: [Az-Geocaching] Help!
