Even if the bottom is at 400 feet?
I'm sorry, english is not my first language, maybe I was not clear. What I meant is in some dives, you have to swim against the current. When you are close to the bottom, that is where you should go, because that is where the current is less strong, most divers know that.
I am trying to show with an exemple most divers know the way I think of wall dives and down current; a down current next to a wall is similar to a horizontal current. The current is less strong next to a surface (the wall).
