RS-790 Regulator Set by Tusa
Dominate Cold Water Dives
Take on freezing temperatures below 50°F (10°C) with total confidence. Dive Right In Scuba brings you the Tusa RS-790 Regulator Set to power your most extreme underwater adventures. The balanced diaphragm first stage features a dry ambient pressure chamber that actively prevents water contact with the internal components. An external ribbed section nearly doubles the surface area for rapid thermal exchange, stopping ice formation in its tracks. You get massive airflow in the harshest environments without any freezing worries.
Breathe Effortlessly at Any Depth
Route your hoses perfectly using two high pressure ports and four low pressure ports. Two of those low pressure ports feature a high flow design that delivers up to a 15 percent increase in air delivery. You pull massive amounts of gas effortlessly when you push your physical limits at depth. You choose between a standard Yoke or a 300 bar (4350 psi) DIN connection to match your specific cylinder valves perfectly.
Maximize Your Dive Comfort
Experience ultimate jaw comfort during long bottom times. The lightweight S-90 second stage utilizes a pneumatically balanced system inside a compact composite case. This specialized housing actively insulates the internal breathing components against extreme cold. An integrated venturi adjustment lever gives you instant control over your airflow. You dial in the surface setting to prevent free flows upon entry and flip to the dive setting for maximum air delivery at depth. The ortho-consciously designed mouthpiece conforms naturally to your bite. Plus, USA customers qualify for the TUSA CARE Free Parts for Life Program to save money on future servicing.
