we are going to talk about Alvin we are not talking about alvin york the famous world war, one hero, we are talking about alvin the submersible. this has a simple system to get to the bottom 4 weights once you reach the bottom. and want to go to the top you pull a lever and it drops the weights meaning you need to have new weights for every single time. and if I were them I wouldn't trust a buttun with my life what if something gets wrong with the circuits it won't activate the clasps with the weights. I would see somehow to do it manually.
