+tandem Posted March 21, 2004 Share Posted March 21, 2004 What is a good water tight containers? I'm thinking of doing a multi cache on a lake we live on. Paddle to different points on the lake to find clues to the final cache. The final cache would be in the lake on a chain. Near my home so I can watch it and maybe meet soom of the cachers that come by. Quote Link to comment
+2qwerqE Posted March 21, 2004 Share Posted March 21, 2004 (edited) I've been using large Coleman thermoses lately. I find them at thrift stores like value Village and Goodwill stores for a couple of bucks. I figure, if it's designed to keep liquids in, then it should be good at keeping them out as well. Haven't sunk a cache in a lake yet, tho. Maybe you could test one out. I'd probabaly calk the spout somehow, or paint it shut. Edited March 21, 2004 by 2qwerqE Quote Link to comment
+wildearth2001 Posted March 21, 2004 Share Posted March 21, 2004 ammo cans or paintball tubes could work Quote Link to comment
+TeamK-9 Posted March 21, 2004 Share Posted March 21, 2004 Actually, if the thermos is a good metal one, it could work very well as your underwater one. I mean, if it was a really nice metal one it would probably sink... Quote Link to comment

+TeamK-9 Posted March 21, 2004 Share Posted March 21, 2004 Oh, I'm an idiot too.... I was thinking since they're so heavy, they'd sink like a rock, but unless you could figure out a way to vaccuum seal it, it would most definately float... Quote Link to comment
+flossmoor Posted March 21, 2004 Share Posted March 21, 2004 Waterproof container: M258A1 Decon. One of my caches this winter (GCHKJM), appropriately named "Fifteen Below", required the container be immersed in water. When the first finders arrived (perhaps 36 hours later), not a drop had gotten inside. Of course, the "water" wasn't always liquid... The decon does not use a gasket like an ammocan, but the lid fits tightly enough to render it waterproof even for (at least short-term) full immersion. Quote Link to comment
+Waterboy Posted March 21, 2004 Share Posted March 21, 2004 Message In A Bottle is a cache that uses a Nalgene bottle. Quote Link to comment
+Lazyboy & Mitey Mite Posted March 21, 2004 Share Posted March 21, 2004 (edited) Ok this is from a diver. Let me assure you that no container stays waterproof forever, none, nadda, zip, nope it ain't gonna happen. My suggestion for any cache that is to be placed in water is to not even try to make it waterproof. Make it a cage type of deal like a crab trap and place only items in it that can sustain water. The logbook can be a dive slate. Simple and foolproof Edited March 21, 2004 by Lazyboy & Mitey Mite Quote Link to comment
+flossmoor Posted March 21, 2004 Share Posted March 21, 2004 This is supportive of a couple of theories... Flossmoor's First Law Of Geocache Entropy: All cache containers, regardless of quality, cost, or planning, will deteriorate over time. Flossmoor's Second Law of Geocache Entropy: Every visit to the cache hastens this deterioration. Even if there was a way to create a "perfect container", it would only be as good as the most recent visitor's care in assuring it is properly sealed. After all, with some variability, one can generally count on at least one in every five visitors neglecting to properly "burp" the Tupperware. Given all this: does anyone's definition of "waterproof" in this discussion include the word "invincibility"? If so, disappointment is imminent. Ammocans and their gaskets come used (sometimes by decades), not new. Decons are a little newer. Both beat Rubbermaid like a Smith and Wesson beats four aces. Quote Link to comment
