Apeks regulators are ideal for use in any diving environment. Their unsurpassed performance under even the most extreme conditions is well known among diving professionals throughout the world. Diving Icon John Bennet, who is the first man ever to SCUBA dive to a depth of over 1000 feet, has long put his faith in Apeks for his record-breaking dives. John says it best when talking about Apeks regulators: "Apeks regulators breathe superbly, they are simply the best." Apeks offers a series of regulators that provide divers with a wide range of benefits. From the practical and robust XTX20 to the ultimate in performance and outward beauty, the Tungsten, all of these regulators share many common features that make them superior to their competition in any price range:

OVER-BALANCED DIAPHRAGM DESIGN
The heart of any regulator is the first stage. Most Apeks first stages utilize a unique Over-Balanced diaphragm design. In an over-balanced first stage design, the interstage pressure in the hose increases faster than traditional balanced models as a diver descends to greater depths. This increased interstage pressure compensates for the increased density of your breathing gas by allowing a larger volume of gas to flow through the system on demand. The result is superior breathing performance regardless of depth. The Over-balanced Diaphragm Design is found on Apeks Tungsten, XTX200, XTX100, XTX50, XTX40 and XTX50/DS4 first stages.

ENVIRONMENTAL DRY SEALING SYSTEM
Standard on most Apeks first stages is the unique Environmental Dry Sealing System. This system serves a number of purposes, including the prevention of ice build up on the main spring that can occur when diving in extremely cold water. Dry sealing the first stage also acts as a safeguard against the entry of contaminants and silt into the main spring chamber, and eliminates the need for messy silicone oil or grease filling inside your regulator. The Environmental Dry Sealing system is found on Apeks Tungsten, XTX200, XTX100, XTX50, XTX40 and XTX50/DS4 first stages.

PNEUMATICALLY BALANCED 2ND STAGE
All Apeks second stages feature a Pneumatically Balanced Valve System. In most second stage designs, the inhalation effort of the diver opens a valve inside the regulator that is held closed by spring tension. In the Apeks pneumatically balanced design, the pressure on the second stage valve is "balanced" by allowing medium pressure air to pass through to the opposite side of the valve to help counteract the force of the spring. This reduces the inhalation effort required to open the second stage valve and substantially improves the overall ease of breathing in all diving conditions.

	Apeks XTX 200 Yoke Part #130 040 Din Part #130 041 In Store Sales Only The NEW 2006 XTX200 model is the flagship of the Apeks® fleet of fine regulators. It uses the proven “FSR” type first stage as found on the ATX200. This XTX200 first stage features a new bright chrome finish. The second stage, although shipped in a standard right-hand configuration, can be reversed into a left-hand configuration by your authorized technician. Available in either DIN or Yoke configurations Compatible to EAN 40 right out of the box Optional DIN to Yoke converter and Free Flow Control device, which can isolate a free-flowing 2nd stage Features All medium pressure ports are now 3/8” so that the reversible XTX second stage can mount to either side of the first stage. The over-balancing feature allows the medium pressure air in the hose to increase at a rate faster than ambient pressure resulting in superior performance. Environmental dry-sealing system New XTX pneumatically balanced second stage has left/right reversibility and a Diver Changeable Exhaust (DCE) system. This system gives the diver the ability to change from a large exhaust tee to a smaller exhaust tee. The large tee provides the best exhaust bubble dispersion; the smaller tee is lighter weight and compact. Both exhaust tees are included with the regulator. Improved exhalation performance and overall work of breathing This pneumatically balanced second stage has diver-adjustable controls for opening effort and venturi control Suitable for cold-water use Indexable, tactile and audible venturi adjustment
