What do you recommend for an underwater cache?

[+figtreesky]

I found an interesting location I want to check out and think might be good for a cache. But I haven't been too imaginative with how my caches are placed, but I hope to change that by placing a cache underwater. What containers would you suggest on using?

 

Also, I tried the search option, but it wasn't working. sorry

While it obviously needs to be waterproof enough to contain the logbook, it also needs to be heavy enough that it stays sunk, but not so heavy that a cacher can't retrieve it.

 

I've never looked for an underwater cache yet. I've always imagined that it would be like that old Busch Beer commercial where the six pack was in the river to keep it cool and the guys pull it out to drink. Ahhhh!

 

You might want to look at likely underwater cache areas, such as Florida and scuba spots, for some ideas. Those cache pages might have gallery photos of the cache containers. some of these are normal waterproof containers that are buoyant but are held down by a rope attached to a weight at the other end. How deep is the spot you are looking to put this cache in?

One that I have used is the "Pelican" brand container. Lifetime guarantee also.

Sounds like a great idea, its one i've considered myself as there is a large lake fairly close to where i live, would you leave a marker on the surface though? As a large area underwater would be difficult to search if deep, seeing as the majority of GPS units wouldn't enjoy a dunking!

Good luck and i look forward to seeing the finished cache

One option is to sink an object with coords written on it pointing to a cache on dry land. That way you don't

have to worry as much about the container and keeping things dry.
