PRODUCT SHOWCASE: The MK25 EVO and MK2 EVO 1st Stages with XTIS set the Bar in Cold Water Technology



Scubapro 6

The latest regulator innovation from Scubapro is the exclusive Extended Thermal Insulating System (XTIS). Available in the MK25/MK2 EVO first stages, XTIS ushers in a new era of cold-water protection for the industry. Combined with other advanced features, you’ll be equipped to go further than ever.

Scubapro 1Scubapro 4Available in EVO first stages, XTIS shields the product’s inner components from the elements. With XTIS, the cold-water protection for the MK25 EVO surges another 30 percent, with an impressive 50 percent boost for the MK2 EVO. XTIS provides divers with an ultra-fast breathing response and instant delivery of airflow with minimal effort, regardless of the water temperature, depth or pressure.

Corrado Cominetti, Research & development Manager explains: “The main target in XTIS development was the best freezing resistance. On the one hand we had the know-how based on our TIS experience, on the other hand it sounded pretty hard to improve what has been achieving great results over the years. Nevertheless laboratory analysis of the prototypes under extreme working conditions showed that a better performance was possible. The final outcome was amazing. The full insulating cover of the wet area slowed down the freezing so much that the improvement vs. TIS was evident. The abbreviation EVO stands for evolution. We couldn’t think of a better name as this step forward is an evolution in regulator technology. We are very pleased with this result.”

MK25 EVO – a top performer even in cold water

In addition to the XTIS, the MK25 EVO is built with highly technical internal components that are all designed to enhance cold-water breathing performance. These include a new spring insulating coating, a new body insulating bushing, a new antifreeze cap, and a bigger body and cap thread. Externally, supplementary fins have been added to the machined body to provide extra thermal exchange.

Like the standard MK25, the MK25 EVO also offers an external intermediate pressure adjustment for hassle-free maintenance, and two high pressure ports and five low pressure ports mounted on a swivel turret for convenient hose routing.

MK2 EVO – the workhorse of the regulators

The MK2 EVO classic downstream piston is delivered with re-worked, advanced components such as a new spring insulating bushing and coating, a new insulating piston bushing, a new insulating sleeve and a new antifreeze cap, all of which work with the XTIS to ratchet up the MK2 EVO’s resistance to freezing and improve its overall breathing capabilities. The body of the MK2 EVO is actually a tad smaller than the standard MK2, even though its piston is slightly larger, contributing to a 15 percent increase in airflow. The new removable orifice (patent pending) allows for easier maintenance and extends regulator life. The chrome plated brass body features one high pressure and four low pressure ports.

The new European EN250-2014 regulator testing standards

The following changes have been made:

  • WOB test parameters have been adjusted down to 2.5 j/l (previously 3.0 j/l)
  • Regulator cold-water tests are run with both single (62.5 l/m for 5 min @ 50m) and simultaneous breathing (560 l/min for 2 min @ 30m/99ft); with water temperature of 2°C

SCUBAPRO sets the benchmark for regulators.

The new MK25 EVO and MK2 EVO are available in the following combinations (DIN and INT) at authorised Scubapro dealers.


MK25 EVO/A700 £609                           MK25 EVO/A700 Black Tech £689

MK25 EVO/G260 £459                           MK25 EVO/G260 Tactical £569

Take an immersive dive below the waves off the Welsh coast using 360 VR: Common Spider Crab (Watch Video)



A week-long series from Jake Davies…

Below the waves off the Welsh coast, there are a range of species and habitats that can be seen. However, you don’t have to venture too far from the shore to see them or don’t have to leave the comfort of your home. Using 360 videos provides an immersive feeling of being below the water and encountering many species and habitats from diving one of the most important habitats and species that aren’t often seen whilst diving. For more of an experience of being below the waves, the VR videos can be viewed using a VR headset.

Take a VR dive just off the shore and explore what can be found within the shallow waters of a sandy beach. Fish can be founding cruising amongst the seaweed and numerous crustacean (Crabs, lobster, prawns, shrimps) species can be found walking around the seafloor. Common Spider Crabs (Maja brachydactyla) are one of the largest crabs species found along the coast and during the early summer, they aggregate in large numbers to moult which allows them to grow.

Explore the amazing triangle of Red Sea Reefs - The Brothers, Daedalus and Elphinstone on board the brand new liveaboard Big Blue.  With an option to add on a week at Roots Red Sea before or after. 

Strong currents and deep blue water are the catalysts that bring the pelagic species flocking to these reefs. The reefs themselves provide exquisite homes for a multitude of marine life.  The wafting soft corals are adorned with thousands of colourful fish. The gorgonian fans and hard corals provide magnificent back drops, all being patrolled by the reef’s predatory species.

£1475 per person based on double occupancy.  Soft all inclusive board basis, buffet meals with snacks, tea and coffee always available.  Add a week on at Roots Red Sea Resort before or after the liveaboard for just £725pp.  Flights and transfers are included.  See our brochure linked above for the full itinerary.

This trip will be hosted by The Scuba Place.  Come Dive with Us!
