A Review of the Scubapro MK25 and A700

The MK25 and the A700, easily one of the most financially demanding regulator sets available on the market today. It grabs attention because of its price tag as much as its polished body and impressive specification. Once it gets a buyer’s attention with its chrome plated veneer, the diver is then faced with the question of whether they are paying for the simple, self-indulgent prestige of owning Scubapro’s top-of-the-line regulator set or, if you are making a sound investment into a piece of gear that will make your dives easier, more enjoyable and that will continue to do so well after you require a walking stick on the shore. I have already made the difficult decision and made the big investment. I’d like to talk about why you might want to reach for your wallet too.

MK25

The MK25 is a well known, well tested prestige first stage. It is a balanced-piston controlled regulator which translates into unfailing easy-breathing at any depth, temperature and tank pressure. With regards hose placement, the 5 low pressure ports and 2 high pressure ports make creating your perfect diving rig a pleasure with little compromise. This is particularly true because the low pressure ports are mounted on a swiveling turret that ensures comfortable routing regardless of set-up.

Only one criticism comes to mind and it is minor; If you are like me and like to wear a big BCD and wear the tank band high on the tank then the turret becomes less effective as the BCD tends to trap the hoses. This can be overcome by having the first stage mounted upside-down which allows perfect freedom of movement.

A700

The A700 is Scubapro’s range-topping second stage. It has chrome-plated brass body which splits opinion on sight. Some love the all-metal design for it’s durability, temperature equalizing properties and it’s size minimizing attributes. Whereas there is another school of thought that feel the A700 is too garish and is overly boastful of its abilities.

Either way you look at it the A700 has serious hardware to back up its loud exterior: it has a superb breathing resistance, flow rate and a truly impressive ability to assist with each breath. The VIVA system and resistance vane are incorporated into one control knob for convenience and the purge button is big and easily depressed.

I won’t preach that this is the best regulator set on the market, but it certainly lives up to that brash exterior and even louder price tag. I would argue that it’s worth the investment.
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 4300psi 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. As a specific anti-freezing measure, SCUBAPRO engineers have designed a patented finned cap for the MK25 first stages for optimal cold water diving. 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 gas pressure drop. For cold water diving, SCUBAPRO’s second stages feature precision molded carbon fiber and techno polymer valve housing and components. They even exceed the CE cold water norm. In addition, these components contribute to their lightweight features and corrosion resistance.
