Default RE: DEEP WATER: Transmission?

80 Bar????? The pressure at 200 ft is no where near 80 Bar (1160 PSI)! The pressure at 200 feet is 8X that of atmosphere, or 8 Bar (116 PSI). Pressure at depth increases by 1 ATM for every 33 feet. Makes a big difference. Samsons pressure vessel should work just fine. He will need a minimum of 3/8 thick polycarbonate for his lens, I'm using 1/2, but my viewing port is 4 1/2 inches.
