Scubapro Regulator | MK25 EVO / S600 from


Scubapro Regulator | MK25 EVO / S600

Because you are worth it.

The MK25 EVO teamed with Scubapro's S600 second stage regulator has been the flag ship set up for the past decade, so it a great choice for you.

It's superior ultra-high airflow system for maximum performance in all temperatures and diving conditions will make breathing underwater second nature, so you can get on with your dive without having to think about it.

The S600 is a light weight second stage with a metal core making jaw fatigue a thing of the past and a reg that will last you a very long time.

Scubapro has been the leader in the evolution of piston controlled first stages since its beginning; the MK25 EVO carries on this heritage with an array of patented features ensuring unfailing performance. The MK25 EVO 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. 

The MK25EVO 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 stage: 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 flowespecially 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 EVO 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 EVO accommodates five HF (High Flow) ports on a swiveling turret, which allows for 360° 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.  

As the MK25 first stage has 5 LP ports, 1 being on the end of the reg it allows great hose routing on the twins.  The turret makes them great on my stage bottles as well as when I am single tank diving.

Comes with full manufacturer's warranty and free shipping anywhere in New Zealand.  As we back all of our products, if you are not satisfied, for ANY reason, then simply return the regulator for a full refund.

We'll assemble and test the regulator onsite so it's ready for you to use straight out of the box.  We strive to provide the best after sales service in the country so once you get the regulator if you have any questions then we are more than happy to help.
