Yes, I'm new here so forgive me if im in the wrong forums. I am currently assembling a submergable underwater camcorder housing of 6" diameter pvc pipe. I was wondering what is the diference between plexiglass and double strength plexiglass concerning the pressure it can withstand. I am going to need to be able to submerge it at most around 2-3ft. I'm sure I can find information on what kind of pressure the water will exhert at 2-3ft below surface, but i don't have a clue what kind of pressure plexiglass itself can withstand. Also if anyone could inform me about double strength plexiglass, would it be any better, or is single strength plexiglass enough to withstand the pressure it will encounter?
