The goal is for this process to take no more than 60 seconds.

You go into the water, you come out of the water, and you're done.

When you step into the water, you’re standing on top of a platform. The platform is connected to rails and begins to descend into the water - an elevator gently lowering you at around 2 inches, or 5 centimeters, per second.

Assuming 30s down and 30s up, this platform will lower you a total of 60 inches, or 5 feet. So even in the magical fantasy land where this works at all you're going to have a great tool to detect what's happening in the body as long as it's below the average person's heart, an organ that is famously unnecessary and irrelevant.
