Scubapro MK25 EVO A700 Review Video
Below is a quick video review of the regulator done by the guys over at Simplyscuba.com. In the video, you can get a closer look at the regulator and some of its features.
Scubapro MK25 EVO A600 Key Features
Below are some the key features that make this regulator stand out from others on the market.
Extended Thermal Insulating System (XTIS)
Certainly the most interesting new feature of the design, attempting to make Mark 25 first stage to perform well even in colder water. Instead of sealing it Scubapro encapsulates main spring bushing and engineers a finned cap with additional body ribs. The ribs 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 drop in gas pressure.
High And Low-Pressure Ports Positioning
Two opposing high-pressure ports allow positioning the first stage in the most comfortable way for any type of mount. Many tech divers report this to be a big relief from the pain of fiddling with older or cheaper regulators. Below swivel turret, five lower pressure ports provide extra flexibility to adjust the setting to your ultimate comfort.
Tough Rigid Design to Withstand Aggressive Diving
Chrome plated first stage and reinforced technopolymer casing of the A700 piece really impressed us. It certainly adds to the overall weight but will prolong the life of your regulator significantly.
Venturi-Initiated Vacuum Assist (VIVA) lever
Inventive free-flow protection that also allows the diver to get extra control on the air supply, on top of the inhalation effort knob.
Scubapro MK25 Evo A700 Black Tech
This version has a extremely scratch resistant coating which also gives it a really cool “Black Tech” look. This is also great if you’re a diver who’s hard on your regulator.

How Does It Stack Up?
First stage careful construction allows maximize hose routing options. Orthodontic mouthpiece and Diver-adjustable VIVA switch just adds to a long list of well planned details.
MK25 always provided the best flow rate, now got a anti-freeze coating and combined with fresh patented solutions is now able to perform even in colder water. Together with A700 regulator they present a top pair for smooth easy breathing under any conditions.
Solid metal casing for A700 and chrome plated first stage are promising a long-term life even in the most rough conditions.
While the price for MK25 Evo is well justified, we think there are cheaper alternatives to the second stage even within Scubapro range, which will not compromise the performance, but save you a few dollars.

What We Like
Airflow and ease of breathing is attended with meticulous attention and Scubapro deliver a supreme performance. From steady flow first stage delivering up to 15% more air than older and cheaper regulators, to oversized bore or the second stage. This ultra-performance regulator will definitely save you air.
Its solid design will save you frequent visits to repair shops even with an extensive diving schedule. It’s a tough buddy you can rely on.
What We Don’t Like
It’s hard to find anything we didn’t like about this regulator, and most reviewers online gave it a perfect score. If there is anything we didn’t like about this regulator it the Price. It’s quite expensive and might not be for every diver.
If you are looking for a cheaper version with similar performance, we would suggest still investing in MK25 Evo first stage, but combining it with G260 or S600 regulator. They a less rigid structure, less compact, but still light and includes the same VIVA system and other perks.
Who Is MK25 Evo A700 For?
Experienced divers ready to pay extra for a high-performance steady regulator will not be disappointed with Scubapro MK25 Evo A700. While it is probably not your first choice for everyday diving in polar regions, it delivers high performance and ultra-steady tuned air supply in all other conditions.
Rigid body design and materials will also withstand extensive traveling. Divers report that banging and falling on a dive boat did not do any damage to any of the parts. All of that comes with two caveats: it is a heavy thing to travel with (1.2 kg without octopus!) and it comes with a hefty price tag.
