1st & 2nd stage
SCUBAPRO MK2 EVO/R195
$679.99
- This is a good entry-level reg for medium to warm water temperatures. It is a proven and reliable reg system, easy to maintain, easy to use and easy on the budget.
1st stage: The MK2 EVO is a downstream piston-style first stage. It comes with SCUBAPRO's patented Extended Thermal Insulating System (XTIS) fully isolating the mechanical elements of the first stage from the cold and hereby increasing freezing resistance by an average of 50 percent over the previous MK2 first stage.
A new spring insulating bushing and coating, insulating piston bushing, insulating sleeve and a new antifreeze cap contribute to the increase in freezing resistance.
Its body is 3.5mm smaller than its predecessor but houses an oversized piston by 1.6mm that provides better breathing performance by increasing airflow by 15 percent.
2nd stage: The R195 combines a classic downstream valve with a large diaphragm, functional purge button and VIVA switch for smooth and easy operation. It is a robust and reliable entry-level 2nd stage with reversible hose attachment. -

SCUBAPRO MK25 EVO/A700
$1,689.99
- The MK25 EVO/A700 combination is the best-breathing regulator in SCUBAPRO's line!
1st stage: Since its release in 2004 the MK25’s quickly made it to the very top of piston design regulators. It is very durable, reliable and delivers extra-high and effortless airflow, regardless of depth, tank pressure or breathing rate. Since 2016 the MK25 benefits from another substantial upgrade, SCUBAPRO's patented Extended Thermal Insulating System (XTIS), giving the reg its new name: MK25 EVO. The system let’s you enjoy all the advantages of an MK25 - regardless of how cold the water is! The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over the - already very freezing resistant - prior MK25 without compromising breathing performance. The key insulation system components are visible in blue.
New spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance.
The MK25 EVO features a swivel turret with five high-flow LP ports (high flow ports deliver about 15 percent more air than conventional low pressure ports). It also has an external intermediate pressure adjustment that allows technicians to maintain peak performance without the need for disassembly.
2nd stage: the A700’s is an air-balanced regulator. Its casing is full metal to take advantage of the extremely high heat exchange rate which makes this second stage such a great choice for cold-water diving. In addition the metal case construction enables the use of a larger diaphragm inside a very compact casing for an ease of exhalation that is unmatched. The air-balanced system provides effortless breathing in any situation. - Designed for cold water diving and Nitrox ready up to 40%
1st stage- Body material: marine-grade, chrome-plated brass

SCUBAPRO MK25 EVO/A700 CARBON BLACK TECH
$2,339.99
- The MK25 EVO/A700 combination is the best-breathing regulator in SCUBAPRO's line. Both first and second stage have a BLACK TECH scratch- and corrosion-resistant coating that protects against the strains of technical diving and the ravages of salt water. This durable coating includes an inner layer of chemical Nickel (FDA approved) and an outer glossy DLC (Diamond Like Carbon) finish
1st stage: Since its release in 2004 the MK25’s quickly made it to the very top of piston design regulators.

The metal case construction enables the use of a larger diaphragm inside a very compact casing for an ease of exhalation that is unmatched.
The screw-down front cover, in place of metal, is hand-made out of carbon fiber - the same material you find on aircraft and high-speed race cars. Carbon fiber is extremely lightweight and, unlike metal that can change shape when dropped or struck against a hard object, carbon fiber can resist substantial shocks without damage.

ZEAGLE ENVOY II
$559.95
- The ENVOY II has a very good value/performance balance. It’s an economical regulator that doesn't compromise on performance or reliability. In function it basically is an ONYX II regulator without the cold water kit, black satin finish and without the inhalation effort adjustment knob on the 2nd stage.
The internal structure allows direct airflow through the 1st stage, providing lower turbulence for outstanding performance.
The high-pressure valve provides much greater reliability and service life compared to conventional designs, while improving responsiveness and performance at all breathing rates.
The braided LP hose provides high flow and tremendous abrasion resistance while having great flexibility. The compact exhaust tee and light weight construction give the ENVOY II a beautiful presence.
Like all ZEAGLE regulators, The ENVOY II comes factory ready for use with EAN/NITROX up to 40% O2. - Designed for water temperatures of 50°F/10°C or higher and Nitrox ready up to 40%
1st stage- Body material: marine-grade brass

ZEAGLE F8
$899.95
- In partnership with Atomic Aquatics, ZEAGLE engineered over 20 different improvements on everything from inner mechanisms and materials to exterior controls and aesthetics. The F8 breathes better, works harder and lasts longer than any other regulator they’ve ever made.
1st stage: The F8 1st stage has a dry-sealed spring chamber (to stop freezing at water temperatures below 40 degrees F). All delicate parts of the 1st stage including the main spring are sealed behind the clear hydrostatic diaphragm away from the effects of salt or other contaminants in the water, making it environmentally sealed. It is very low in profile, barely extending above the tank valve, and places the low pressure hoses directly out to the sides, in a pattern preferred by many divers.
New Neoflon seat: The conical precision high-pressure valve provides much greater reliability and service life compared to conventional designs, while improving responsiveness and performance at all breathing rates.
Work of breathing at heavy* demand: 0.72 Joule/Liter *198 (60M) depth, 750 psi inlet, 62.5 RMV (liters per minute respiratory volume)
Like all Zeagle regulators, The Flathead-8 comes factory ready for use with EAN/ NITROX to 40% O2. -
2nd stage: A new inhalation diaphragm provides superior tear strength and improved response time to breathing (super soft silicone molded over a low friction disk). The improved exhaust valve ensures dryness and a lower exhalation effort.
Another revolutionary difference to most regulators is the seat-saving orifice. It is not screwed into its base, it can move. The sharp edge of the orifice is the part that is sealing against the teflon seat of the 2nd stage when you are not inhaling to stop the airflow. In common systems, when the reg is not used, these 2 parts are resting against each other, meaning the sharp edge of the orifice is cutting into the seat.
With the F8 these 2 parts don't rest on each other and the seat doesn't get used while in storage. Only when you turn on the tank (put air in the system) the flow of air will push the orifice against the seat, creating the seal.
The seat is made of soft silicone molded over a metal insert to deliver the firmness required for an airtight seal while maintaining the necessary elasticity to prevent leaking.
Redesigned front cover and inhalation effort control knob use co-molded components that provide the necessary grip, soft touch and ease of use.
The redesigned heat sink dramatically increases surface area thus aiding in the heat exchange necessary to avoid freeze-up. In addition the heat sink and inlet tube are zirconium-plated for superior corrosion resistance.
Several color kits are available for the F8 2nd stage to perfectly match your gear or mark different gasses. - Designed for cold water diving and Nitrox ready up to 40%
1st stage- Body material: marine-grade brass with black satin chrome finish

The internal structure allows direct airflow through the 1st stage, providing lower turbulence for outstanding performance.
The high-pressure valve provides much greater reliability and service life compared to conventional designs, while improving responsiveness and performance at all breathing rates.
The braided LP hose provides high flow and tremendous abrasion resistance while having great flexibility. The compact exhaust tee, advanced black satin chrome finish and light weight construction give the ONYX a beautiful presence.
