We have never found a cache while magnet fishing. As for the container design, I was thinking of a small plastic container weighted down with large metal washers glued to it. I’ve pulled up many metal washers magnet fishing. OR, a container with a metal weight like a lock attached to it so that even if the plastic container is buoyant, the metal attached to it is enough to keep it submerged in one place. Hubby and I may need to experiment to see what works. I’m afraid a metal container holding the plastic one will either open and lose the cache or keep rusting pretty quickly that it would need to be replaced multiple times.

My husband and I recently started geocaching. We both love magnet fishing. Once we are ready to hide our first caches, are we allowed to hide a cache underwater that would require a magnet to retrieve?
