Vintage Scuba: Surface Pressure Checkers - S02E09

Long before Submersible Pressure Gauges (SPGs) were invented, divers manually checked tanks before and after dives with a 'pressure checker'. Alec shows several gauges and explains their unique features back when a scuba tanks maximum pressure was 2475 psi (170 bar).
