About TUSA X-Pert Regulator (RS-460)

The R-400 First Stage Regulator features a Balanced Diaphragm System Design and Upgraded HP Poppet Assembly for Enhanced Reliability. This Balanced Diaphragm System Maintains Minimum Variation in Intermediate Pressure in relation to Changes-in-Residual Tank Pressure. The Balanced Diaphragm, First Stage Regulator is inherently Environmentally Sealed. The benefit of this type of first stage design is that none of the delicate internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants can cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.

The First Stage feature Two High-Flow Low-Pressure Ports (LP) to Optimize Second Stage Performance for Easier-Breathing. The High Flow Ports are engineered for the Smoothest-Air-Delivery possible to the Primary and Octopus Second Stages at all tank pressures. The Diaphragm First Stage also offers Excellent-Performance in All-Water-Conditions due to its Sealed Design. The R-400 First Stage features a Special Coating on the Main Spring to ensure that the Regulator Performs in All-Diving Conditions including Cold Water. The R400 First Stage also comes equipped with One-Standard LP Ports with 3/8" Threads and One-High Pressure Port (HP) with 7/16" Threads. The First Stage Regulator weighs 1.87lbs (850g).

The S-60 Second Stage features a Diver Adjustable Sensitivity Control to Deliver-Air-Smoothly with Each-Breath. The "Surface" or "Dive" Control allows the user to set the Ease-of-Breathing for Varying-Sections of the Dive. The Surface" Position Decreases the likelihood of a Free Flow and also is recommended for Cold Water Diving. In the Dive" Position the Control allows the Regulator to Power-Assist the Diver as they Breathe using a Venturi Effect. The Exhaust Valve features a Large-and-Flexible design for Extremely-Low Exhaust Resistance. The Second Stage Regulator comes with a 29" (74cm) Low Pressure 3/8" Hose and the Second Stage and Hose weigh 0.33lbs (150g). The Regulator System comes with an Owner's Manual and is covered by a Limited Lifetime Warranty.

    I have over 20 dives on this reg now and after I changed the mouthpiece I like it. I dive about 3-4 times a year (50-60 dives) and this will do just fine. The fisrt stage is pretty light which is good for travel
