Description
The TUSA SS-81 safe-second features a venturi adjustment lever in a compact case design with an ortho-consciously designed mouthpiece. The light weight, durable second stage is built to withstand heavy use while maintaining exceptional breathability.This simple second stage with non-compensating downstream valve has a Venturi control to prevent free-flow while diving and to improve breathing resistance when needed. The Venturi Flow Adjustment allows for ease of breathing by controlling the direction of air through the mouthpiece. The adjustable control knob is designed to better control breathing resistance. The Sequence Exhaust Assist (S.E.A.) System gives the diver less resistance when exhaling due to its unique double exhaust design. The diver experiences smooth breathing cycles reducing air consumption and fatigue.
