Regulators

To a diver, a regulator is much more than a collection of valves and springs.  It is the heart of a scuba system...a life support system that provides air in an airless environment.  In this demanding world, "high performance" in a regulator has real meaning and measure, far beyond its ability to deliver volumes of air.

Your selection of an Air Delivery Regulator - one that will serve you in all diving conditions - is the single most important decision you will make in the purchase of your scuba diving equipment.  

Your regulator should be able to provide you with a sufficient amount of air at depth.  The amount of sufficient air at depth is determined by environmental conditions, the amount of work we do underwater and our physical conditioning.  Your regulator should breathe so easily, that you almost forget you have it!

When you purchase your new regulator from Scuba Sciences, you will receive much more than a great regulator!  You will receive:

  • Complimentary hose mesh (your choice of colors) installed on the primary and safe second regulator hose (a $25 value!)

  • Complimentary hose protectors installed on the primary and safe second regulator hose

  • One of the country's most experienced service technician for servicing

  • Warranty service for your limited lifetime warranty (certain manufacturer's only)

Choosing Your Regulator Package

    First, choose your first and second stage regulator

    Second, choose your octopus (Safe Second Stage Regulator)

    Third, choose your gauge or dive computer

    Finally, choose a regulator bag to protect your investment

Take a look below at the different types of regulators:

 

 

MK25T (Titanium)

  • Solid Titanium body and components, forget Titanium yoke

  • Patented over-balanced composite/stainless steel piston

  • TIS (Thermal Insulating System) on piston and spring

  • Externally adjustable intermediate pressure (patent pending)

  • New wound conical single stainless steel wire filter

  • Enlarged water balancing chamber holes

  • 5 High flow low-pressure swivel ports

  • Dual high pressure ports

  • Available in yoke or DIN (not shown) configurations

X650

  • Straight coaxial flow valve

  • New smaller popper with quicker dynamic response to inhalation demand

  • Diaphragm and exhaust valve positioned below the mouthpiece.  This structure, in combination with a streamlined shape and lighter weight minimizes jaw fatigue

  • New 15% wider exhaust valve 20% less exhalation effort than the other second stages

  • Dive/pre-dive control switch to prevent accidental free-flow

  • New diver adjustable inhalation control

  • Lightweight orthodontically designed mouthpiece, which reduced jaw fatigue and gum irritation

MK25T/S600T
This is a heavy duty, high performance regulator system popular with experienced and recreational divers who appreciate ultra-smooth air delivery and maximum breathing performance. You don't need to be a professional diver to value the performance of the MK25T/S600T. This regulator is a great investment because all divers want optimum performance.

MK25/X650
This breakthrough design sets a new level of performance worldwide. The ultimate in first stages combined with our newest, and most technically advanced, ultra performing second stage. The construction the first stage gives it excellent resistance to corrosion, durability as well as faster dynamic response and extra high flow. The second stage was developed to improve regulator performance in every area. For extra demanding divers that want the top of the line regulator.

MK25SA/S600
This is the lightest weight 1st stage in our range of regulators and is the ideal 1st stage for traveling. Although the body and additional elements are made from a new light-weight marine-grade aluminum alloy which is virtually corrosion proof, the vital parts most often exposed to excess shock and strain are manufactured from solid stainless steel for optimal toughness. The performance is identical to the MK 25 AF. Body machined and yoke forged from a special aluminum alloy for minimum weight. Yolk screw, yolk retainer, swivel and seat adjustment parts are all in solid stainless steel to increase overall resistance. The special adapter located on one HP port, needed to attach the SPG, is made of stainless steel, eliminating any potential corrosion problem.
