About Scubapro MK25/A700

The MK25 teamed with Scubapro's exceptional new A700, offers Superior Ultra-High Airflow System for Maximum Performance in All-Temperatures and Diving-Conditions. Scubapro has been the Leader in the Evolution of Piston Controlled First Stages since its beginning; the MK25 carries on this heritage with an array of patented features ensuring Unfailing Performance. The MK25 is a Balanced Piston First Stage, Scubapro's Absolute-Top-Performer. It is a Superior-Regulator thanks to its Ultra-Stable Intermediate Pressure (IP) resulting in an Extremely-Punctual-and-Constantly-High-Delivery of Air. This means Instant-Airflow at Any-Tank-Pressure and Water-Temperature for a real Carefree-Dive.

Air Balanced, Flow-Thru-Piston- First Stages with Air Balanced Pistons deliver Significantly-More Air to the Second Stage than any other First Stage, while their performance is totally unaffected by the changing tank pressure. A Balanced Piston allows the use of Lighter-and-More-Sensitive Components, resulting in Ultra-Fast Breathing Response, instant delivery of air on demand, and extra high air flow, especially in low tank pressure ranges. The tired diver benefits from a smoother breathing regulator during the ascent or deco stop. Balanced Piston First Stages are the first choice of demanding sport divers and professionals. A Balanced Piston performs equally in warm and cold water environments.

The MK25 has two opposite High Pressure Ports (HP). The arrangement of high and low pressure hoses is crucial to diving comfort. Two opposite HP Ports allow for an individual positioning of the first stage (pointing up or down). This allows the diver to position the gauges either on the right or left side and increases the freedom of movement for head and neck. Multiple Low Pressure Ports (LP) - For ultimate freedom in the arrangement of LP hoses, the MK25 accommodates five HF (High Flow) Ports on a Swiveling Turret, which allows for 360° Degree Swivel of Hoses. High Flow Ports deliver about 15% more air than conventional ports. Externally adjustable intermediate pressure- Allows authorized Scubapro service technicians to quickly fine-tune and adjusts the first stage after maintenance without the need to disassemble it.

Cold Water Diving with Scubapro-Diving conditions can be drastically different, including extreme cold water and outside temperatures, posing the possibility of a regulator "freezing". Therefore, Resistance-to-Freezing is Imperative for the diver. All Scubapro Regulator Systems are CE Approved for 3360psi (230 bars) Cold Water Diving. Some models go even beyond this Super-Stringent-Qualification and have successfully been Tested-in-Extreme-Cold-Diving-Conditions at less than 36°F (2.2°C). As a Specific-Anti-Freezing-Measure, Scubapro engineers have designed a Patented Finned Cap for the MK25 First Stages for Optimal-Cold-Water-Diving. This Finned Cap is a Thermal Insulating System (TIS).The Ribs of the TIS Act-as-a-Radiator to Increase the Surface-Area of Heat-Transfer from the Water to Warm-Up the Internal-Parts that have been Drastically-Cooled-Down by the Gas-Pressure-Drop. The MK25 is manufactured from Marine-Grade Black Chrome Plated Brass. The MK25 First Stage offers a Balanced Composite/Stainless Steel Flow-Thru Piston that would make any diver proud. It demonstrates Scubapro's dedication to quality and creating positive diving experiences.

Scubapro has once again raised the bar for regulator performance with the introduction of the A700 second stage. It is truly the crown jewel of the Scubapro regulator line. The A700 delivers extraordinary breathing performance in a striking, precision-handcrafted, full metal design. Whatever your dive destination, the Scubapro A700 lets you breathe effortlessly and naturally underwater for a lifetime of exceptional dive experiences.

Small and compact for comfort in diving, this air-balanced valve technology regulator has minimal inhalation effort and super high-flow exhaust valve for ease of inhalation and exhalation at any depth or dive condition. Regulator is equipped with a diver-adjustable inhalation knob for fine tuning of breathing resistant's and diver-adjustable VENTURI-Initiated Vacuum Assist (VIVA) for additional inhalation assistance and free-flow prevention. The A700 has a High Comfort Orthodontic Mouthpiece. The MK25/A700 Regulator comes equipped with a 3/8" Threaded Super-Flow Hose with Strong and Durable Kevlar Lining and a Super-Comfort High-Flow (HF) Mouthpiece for Smooth Air Delivery. The Scubapro MK25/A700 Regulator, weighs 38.4oz (1,090g), comes with an Owner's Manual and is covered by a Limited Lifetime Warranty.

Scuba Pro


from Bellingham, WA, US

Love the regulatory heavy but built old school style??


Always wanted a Scubapro regulator.


Nice device. No problems. Would buy again.




Like the small size. Breathes nicely. Still a bit noisy but that's ScubaPro but it'll still be working 20 years from now.


Breathes sweetly


Great overall design.


Great Reg! Love it.


Breaths great no matter the depth. well built and reliable.

Questions about this item:

Shopper  Why Did You Choose This?
CHRISTOPHER L  I've been very happy with this reg...breathes super easy and is the quality you'd expect form SP. You'll never go wrong with a MK25, I'm partial to the tech black finish though.
JOHN G  I needed a replacement regulator for the old
scott w  what is the difference between the scuba pro M25 A700 and the M25 Evo/ A700?
JAKE T  Looks like Scubapro has made changes to the MK25 first stage, supposed to have something called XTIS (Extended Thermal Insulating System): "with mechanism fully insulated from the environment, improves cold water/ freezing resistance without compromising piston breathing performance. (Patent pending)".
Karl Z  Which would you recommend when it comes to performance and durability in the most demanding & extreme of conditions if your life were to depend on it? Hands down no questions asked. A. Scubapro MK25 EVO/A700 B. Mares Abyss 22 Navy II
LIS Y  I don't know the Mares, but I would recommend the A700 hands down. Had it for5 years. It's a real workhorse. Perfect every time, that delicious air flowing just right all the time so you don't even remember you have a reg in your mouth and can attended to other things. I dove the Persian gulf in very very warm water, Bali and Maldives in cool-ish water and Africa in strong currents. Never an issue. And it looks really cool too. I love my 700. Good luck and happy diving.
JOSEPH S  I have not used the mares abyss. scubapro MK 25 is a exellent reg. I have 3 and use on cold and warm water diving. easy breathing very dependable never had an issue
