Olympus TG-4 + PT-056 housing to depth of 190ft

Hi all,

I currently own the Olympus TG-4 camera (waterproof to depth of 50ft) and want to take it on a diving trip where I will get down to depths of around 190ft. I see there are housings that are rated for this depth but they are a fair bit more expensive than the PT-056 housing, which is only rated to a depth of 150ft. I was wondering if the physics works out to keep everything within rated pressures if I take the housing and camera down to 50ft before closing and sealing the housing - this would mean the housing would be filled with water at a "pressure" of 50ft, which is within the camera's limits, and then the external to internal "pressure" on the housing at my max depth of 190ft would be 190 - 50 = 140ft, which is within the housing's pressure ratings.

Does this make sense, or am I missing something?

Thanks!
