Excuse my rookieness, but a quick calculation:
200m ~ 656 fsw
656fsw/33 = 19.9 ATA
(Since the handset is already at 1 ATA, we can ignore ambient pressure at the surface, since it's equal)
19.9 ATA * 14.7psi/ATA = 292.5psi

So the handset is experiencing about 20x the pressure at the surface, or 293 psi.
