I think that should be strong enough for 75 to 100 feet. The sub I'm working on uses 3/8 thick steel with a working depth of 250 ft and crush around 700 ft. If you keep to the depth your talking about you should be fine. To simplify the depth gauge issue attach a divers depth gauge outside your viewport.

 

If you need any more ideas. Let me know.

    To anyone that might know,

        I have a 500 gallon propane tank with a .312 thousands thickness and was wondering if that might be able to stand pressure of 75 feet or so, I know that some are not keen on using one but I really want to build a sub but do not have some of the resources that some might have. Also, I was wondering how to make a depth gauge.

        Thank you, Mike
