You guys are forgetting one thing....a 5 foot deep hole in florida Beach sand is virtually impossible by hand !! Go ahead and try....its a challenge just to keep it from filling and collapsing in on its self. Your gonna scoop out enormous amounts of sand, because the hole will have to be at least as wide as it is deep. And if you haven't hit water it's a miracle ✨️ 👌!! If your working in the kinetic surf zone, or intertidal zone you will have great difficulties !! Not totally impossible, but very difficult with out heavy equipment.
