Long-Term Burial of Items Prone to Rust

[davsel]

PVC tube - Fill with motor oil

Decoy can not likely to work. I suspect anyone with a detector simply needs to go back over the hole after pulling out the decoy to see if that is all that is in that spot.

Bury next to a metal fence post or along side a metal utility pipe/well pipe/ground rod, or deeply buried/tangled rebar - anything that is difficult to remove. This prevents removing the decoy and rechecking the spot.

Ammo in sealed container with oxygen absorbing packet.
