We decided that instead of showing the base aswell as underwater, we'd just show the underwater in the sequence. By having the base above aswell it would take the audience out of the suspense, and letting them have a breather, but I think by purely focusing on underneath it keeps the constraphobic element! So this is why we're going to just show that there is a base through dialogue and props (walkey talkey).

Here are some of the controls, of what we'd like to be in the submersible!
