Omicron Posted September 16, 2002 Share Posted September 16, 2002 Hey All...been doing some searching, and I can't seem to find any underwater caches. Is this because they don't exist, or am I just being dense? I'm looking for any cache that would require scuba diving to find - I suppose snorkeling would be OK as well, but I would prefer one where diving would be a requirement. Just curious if you know of any of these caches in Wisconsin! Quote Link to comment

Just curious if you know of any of these caches in Wisconsin! There's one in southern Wisconsin called "Under Where?" I have not been to it, but many have. It was named a WGA cache of the month. It's out of comission at the moment, but should be back soon. http://www.geocaching.com/seek/cache_details.aspx?ID=25257 Quote Link to comment
+JBird77 Posted September 17, 2002 Share Posted September 17, 2002 I Dive, and think that would be cool in Michigan, BUT unless you have some special Navy GPSr, what type or coodinants would you use. Anybody know of Michigan Underwater Caches? JBird77 Quote Link to comment

Priebe's Pride Posted September 18, 2002 Share Posted September 18, 2002 I am confused about why you would need a special GPS. All you would need to do is make sure that you have a waterproof solution, even temporarily. Read the cache description. It will help you alot, as will the logs. ProStreet put alot of effort into this one, and If I could swim well enough.... Quote Link to comment
+kbraband Posted September 18, 2002 Share Posted September 18, 2002 I agree with Priebe's Pride. The same type of coordinates used on land will work to find a spot out on a lake. What's up with that talk about a special naval GPS? Quote Link to comment
+jonsom Posted September 22, 2002 Share Posted September 22, 2002 In searching for GC75A2 The Sunken Treasure of Fishtrap Lake my GPSr lost its signal when I was snorkeling on the surface with my GPSr less than 1 foot under the surface. It might have been because the signal was being blocked by my body too. My GPSr (Garmin) has a rating of IPX7 or submerged to 1 meter for 30 minutes. Quote Link to comment
+JBird77 Posted September 23, 2002 Share Posted September 23, 2002 After logging my prior note, I searched and found the underwater cache in Indiana, it looks awesome and wish I found it earlier this summer. That would be awesome to place one in the quarries I dive at in Ohio. I was primarily joking about the "navy GPSr", sorry, I have a dry sarcastic humor that's tough to put into text. It's pretty obvious how you need to search. I don't think I want to Dive with my eTrex even though they say it is waterproof to a degree. Later, JBird77 Quote Link to comment
+Indy Diver Posted October 5, 2002 Share Posted October 5, 2002 This cache is not underwater but you have to Scuba dive to find the location of the cache. http://www.geocaching.com/seek/cache_details.aspx?ID=33401 Quote Link to comment
Keystone Two Posted October 20, 2002 Share Posted October 20, 2002 Here's what I remember from my dive class. You know those nifty waterproof disposable cameras? They are only good for 10 - 15 feet underwater. At that point the plastic begins to implode from the pressure. Even the $100-$150 so-called waterproof cameras have the same limitation. The only truely waterproof solution is a Nikon = many $$$ My point is, even though my Garmin SAYS it's waterproof, I really attribute that to rain-storm protection, not submersion protection. Maybe there's some sort of clear dive-box of a thick material that would withstand pressure. No amount of zip-lock bagging will help at all below a few feet. This sounds like a fun idea. If anyone has the solution, I'll be looking for it in the coming days. Quote Link to comment
+Scook Posted October 20, 2002 Share Posted October 20, 2002 Even though you can make your GPS waterproof, that does not make it usuable underwater. I don't have the definitive answer but the GPS signal will not penetrate very far through water. Why don't GPS units work under heavy tree cover? It's due to the loss of signal from the blockage of water-containing foilage. Dry wood does not block the signals very much but rain and heavy cloud cover do interfere with reception. Submarines can only receive special utlra-low frequency radio signals underwater. There are special transmitters for their navigation use. Quote Link to comment
+JBird77 Posted October 23, 2002 Share Posted October 23, 2002 Those disposable camaras actually can go much deeper than the rated 10-15ft. Its not the plastic emploding that hinders them, it is the winding wheel mechanism. I have taken the cheep disposables 40ft free diving and winding it after I reach the surface for a breath, then going back down for another shot and it was fine doing that all throughout the dive and the pics came out ok, no leakage or anything.

+Mas Posted February 25, 2003 Share Posted February 25, 2003 How about leaving your GPSr at the surface? Wetbag and a buoy with an inflatable flag/marker? Dive and search a 50ft sq. area. You can even drop an "anchor" attached to the buoy with your GPSr. Just some ideas. Quote Link to comment
