I've seen dc players drop depth charged on me in shallow water but they set them way too deep even if I was at the bottom of the shallow sea. The depth charge would pass through the bottom of the floor in SHII and then detonate. Now in real life I know it doesnt burrow into sand and that it would just lay on the bottom but what happens if it cant reach its depth mark? Does it self destruct after many minutes? At least hedgehogs eliminate themselves when they hit bottom.
