+wavector Posted June 17, 2007 Share Posted June 17, 2007 We've been thinking of placing an underwater cache for a while, one that only requires snorkel equipment (approx. 10-15' deep). I was wondering if anyone had any advice for putting the cache together; Containers, writing materials, anchoring ideas, etc. Any advice would be appreciated, thanks. Here is what I did: I used three containers, the first or outer container is a lemonade powder container that is water resistant. It is water proof under several feet of water but pressure at 14' diminishes waterproof to water resistant. This outer container is filled with concrete and the concrete is full of steel bolts, this makes it very heavy. The outer container has some air volume at the top and this helps it "stand up" when it is underwater. Inside the outer container I placed a beach safe with an O-ring, there is a space in the concrete where the beachsafe is nestled. The beachsafe is water proof and because the outer container is almost water proof the beachsafe has never been subjected to the pressure at depth. Inside the beachsafe I use a diabetic test strip container to hold the log sheet. Since our lake is seasonal I move the cache from the shore to deep water each summer. This year the hiding spot on the shore ended up underwater but the diabetic test strip container did protect the scroll. Since it is a microcache I added the coordinates for another nearby small cache to the log sheet, if you find Swim then you get to find a small cache on dry land which can contain TB's, geocoins or small trade items. The cache page contains some pictures of the cache itself. Have fun, I know that my underwater cache is a lot of fun to maintain! Quote Link to comment

+seldom|seen Posted August 4, 2007 Share Posted August 4, 2007 There are a couple in Wisconsin, one in Oconomowoc at the base of a dam which sat undiscoverd for a year and one (mine) in Lake Winnabego that went for about a month a half. Both of these have just a handful of logged finds. Quote Link to comment
+GManSan Posted August 18, 2007 Share Posted August 18, 2007 I was researching caches on Santa Catalina Island off the coast of California (Los Angeles). I found this one: Captain Jacques Yves Cousteau (GCJ9YK) Quote Link to comment
+ClayJar Posted August 20, 2007 Share Posted August 20, 2007 One little note: If you're going to include a logbook, I *highly* recommend using a DuraRite notepad, *NOT* just a plain or even "Rite in the Rain" notebook. The DuraRite ones (by the same company) are completely synthetic paper and do not degrade when used underwater (or left there a long time). Shipping's a killer for small orders, but GearMechant.com had great prices on them when I bought a few to use with our dive team. Quote Link to comment

Mooselake Posted January 17, 2009 Share Posted January 17, 2009 (edited) The problem with caves is there is bad enough reception in buildings much less x number of feet of rock and dirt. so caves are out this is from a one above where I accidentally put the wrong quote Edited January 17, 2009 by Mooselake Quote Link to comment
+PorscheSpyder Posted March 15, 2009 Share Posted March 15, 2009 I recently read in the Complete Idiot's Guide to Geocaching that there was a cache placed 1.4 miles down in the Atlantic ocean on July 19, 2002! The guy used a Russian Mir sub to place it and placed a TB in it. The TB's number is: TB31F1. Whether it's still active I'd sure like to find out! I wonder if anyone got the FTF on it?

Mostly because of the depth. Hold up your arm in front of you, with the palm facing outward. Now look at your pinky nail. The cache, an otter box, looks about that big from the surface and is only slightly lighter than the surrounding colors. It is tied to the roots of a submerged tree, but that isn't visible from the surface at all. The coords will get you withing 20 feet, but it is still a bit of a search. But that is all part of the fun! Quote Link to comment

+Kerewin0430 Posted January 3, 2012 Share Posted January 3, 2012 There are two awesome underwater caches in Hawaii that we found out about last week. Snorkle equipment required, each about 1/2 mi offshore. My brother lives on that beach, but we only had time to find one (http://www.geocaching.com/seek/cache_details.aspx?guid=d668481c-a59a-404d-9550-b9c0eb6130fc) before heading to the airport. The other is close nearby. Caches are Nalgenes attached to chain attached to cinderblocks; both 5/5. I'd "favorite" this one, but I'm not a premium member! :-) Quote Link to comment

Jacath_6 Posted March 29, 2013 Share Posted March 29, 2013 I thought you could not have a under water/ground cache. It doesn't say anything about caches underwater, I've been researching it since I am an avid abalone/spearfishing diver. I am gearing up for a 15 foot underwater cache that I plan to plant in a week or so. They do mention no caches buried in the ground and I'm pretty sure that's a rule so we don't all go gopher hole digging...tearing up the landscape. Quote Link to comment

+JKMonkey Posted May 17, 2013 Share Posted May 17, 2013 always thought that underwater caches were dumb because there's a high risk of the log being ruined and can be dangerous depending on where they can be Quote Link to comment
+cerberus1 Posted May 17, 2013 Share Posted May 17, 2013 always thought that underwater caches were dumb because there's a high risk of the log being ruined and can be dangerous depending on where they can be You may think they're "dumb", but hundreds (maybe more) look for 'em. We've found four of those hides and had a lot of fun. - Boy I feel dumb... The D/T ratings lead one to what kind of hazards may be presented and most prepare for it. Often the antis on higher terrain/difficulty hides are the ones who don't (or can't) do them. It "can be dangerous" anywhere. Carnival food I worry about. Quote Link to comment

They do mention no caches buried in the ground and I'm pretty sure that's a rule so we don't all go gopher hole digging...tearing up the landscape. Since you mentioned abalone diving I had to check your profile to see if you were from where I thought you are from (I was right). I was born in the town where you placed your caches. There's aren't too many places left where you can get abalone but when I was a kid there were a *lot* of abalone there. Quote Link to comment

+Bohemian1966 Posted September 17, 2015 Share Posted September 17, 2015 (edited) I am extremely disappointed In Florida's lack of representation here. I not only thought underwater caches would be more prolific but that Florida would be a leader based on the shear availability of optimum sites which includes a tons of easily accessible springs. As much as I would like to place a SCUBA one, I think a cache that is achievable with snorkel gear is more inclusive. As I learn more about proper placement rules I plan to make a few underwater ones, one fresh one salt, that will do our state proud ! Besides... its freakin' hot as hell and wet down here anyway from the non-stop summer of rain... might as well be in the water. Edited September 17, 2015 by Bohemian1966 Quote Link to comment
