The PX100 includes a simple piston first stage, a primary second stage, an octo and two Miflex hoses. The first stage is made of chrome plated marine brass. It has one high pressure port and four low pressure ports. The second stage features a large diaphr agm for easy, natural breathing at depth and easy activation of the purge. A perforated cover protects the internal components and prevents free flow in current. An adjustable Venturi prevents free flow at the surface.
