            Halcyon Halo Second Stage Regulator

            $412.95

            Breathing underwater should feel natural, and that experience is one of the things that most clearly separate Halcyon second stages from our competitors.

            Category: Halcyon Regulators
            • Description

            Product Description

            • Balanced, adjustable downstream valve
            • Adjustable inhalation resistance
            • Air Control Vane (ACV)
            • Compatible with 40% Nitrox
            • Bench testing by an authorized Halcyon regulator service technician is recommended prior to use

            Breathing underwater should feel natural, and that experience is one of the things that most clearly separates Halcyon second stages from our competitors. As soon as you experience the smooth, high volume of air delivered by a Halcyon second stage, you will be hooked. Our high quality second stage regulators provide diver adjustable controls for the ultimate in breathing performance.

            Halcyon’s Halo second stage offers steadfast reliability and impeccable performance. Two methods of breathing adjustment make it the top choice for demanding Halcyon divers.

            Balanced, downstream valve offers incredibly smooth breathing in all conditions. The design slightly offsets the force of the downstream air entering from the first stage, allowing reduced spring tension and a decreased inhalation resistance. Halcyon first stages are balanced, so the Halo is a perfect fit with either the H-75P or H-50D Halcyon first stage.

            Adjustable inhalation control refines breathing effort by way of an easy access control knob. This allows the demanding diver an opportunity to fine-tune the air delivery of the second stage. Meanwhile, our Aura second stage features a pre-set inhalation effort that suits the most common diving conditions, and can be fine tuned by an authorized Halcyon Dealer.

            • Scubapro MK21/S560 Regulator

              $969.99

              Lightweight and compact, this versatile breather offers superb performance and value – plus a whole lot more.

              The compact and lightweight MK21/S560 is a full-featured reg combo that’s easy to use, offers SCUBAPRO reliability and is priced right, making it the ideal mid-range system for a variety of diving scenarios.

              The MK21 is SCUBAPRO’s first balanced-piston first stage to be released since the introduction of the MK25. It is smaller and lighter than the MK25 and uses a smaller piston, but it delivers the same level of breathing performance, no matter how hard you’re breathing, how deep you’re diving or what your pressure gauge reads. The MK21 also provides exceptional resistance to freezing due to the thermal exchange produced by the external fins on its polished chrome brass body. The MK21’s innovative “smart” hose layout comes with a standard cap with four low pressure ports angled (+/- 20º) to maximize hose routing. This standard cap can be replaced with an optional cap that offers four low pressure ports at more extreme angles (0°/30°) plus a fifth centralized high-flow low pressure port — a useful configuration for technical diving.

              The air balanced S560 second stage features a lightweight techno-polymer casing and comes with full user controls, including an inhalation effort adjustment knob and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch. It can be counted on to breathe dry and easy, regardless of depth or your position in the water.

              The MK21/S560’s size and weight make it an excellent choice for travel divers, its innovative fin design makes it a good cold-water performer, its “smart” hose layout is well-suited for some technical applications, and its overall ease of use, reliability and price make it the must-have reg system for recreational divers of all skill levels.

            • Scubapro MK25 EVO/S600 Regulator

              $1,319.99

              Newly restyled for 2013, our best-selling S600 is continuously evolving and is in its 5th edition. Timeless design and chrome plated marine grade brass make this high performing system a classic.

              Our top performing balanced piston first stage paired with our high performance air balanced second stage; this combination is SCUBAPRO’s most popular regulator combination. The S600 truly matches the  MK25’s characteristics and thanks to its adjustment possibilities, it adapts to all diving conditions and all diver preferences. Ease of breathing is the essence of this system.

              • The MK25 first stage is our absolute top performer and is a superior regulator thanks to its ultra stable intermediate pressure resulting in an extremely punctual and constantly high delivery of air.  The means instant air flow at any cylinder pressure and water temperature for a real carefree dive.
              • Paired with the air balanced high performance S600 second stage, this system is our top performer.
              • Balanced flow valve provides constant & effortless air flow.
              • Diver adjustable inhalation control enables personal adjustment of breathing effort.
              • Diver adjustable Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive control switch and extra high flow exhaust valve account for easy inhale & exhale.
              • Super-flow  hose for smooth air delivery.
              • Precision moulded, lightweight components and anti-freeze materials provide high corrosion resistance and enhance cold water performance.
