What Is the Scubapro MK25 A700?

The Scubapro MK25 A700 is a pricey regulator but it is one of the best you can buy. Regulators have to work harder to deliver air from your tank as you dive deeper underwater with atmospheric pressure changing the deeper you go. Because of this, most people report with most regulators that the air feels “thicker” as you breathe farther below. With the Scubapro MK25 A700, it has been reported that not only does this regulator deliver thinner air than other regulators, but that it does so effortlessly. The air delivery has no drag no matter what your depth, even with repetitive breath.

The Scubapro MK25 A700 regulator has been put to the test under load and has proven superb performance. This regulator even did well upside down while not allowing in any water whereas other regulators failed this test. The Scubapro MK25 A700 has been reviewed by divers as being the best on the market. This regulator is well worth the price you’d pay in comparison to others.

While the lifetime warranty, titanium construction, and swivel design of the Atomic Aquatics T3 regulator are attractive features, it comes with a high price tag. For this reason, our best pick is the Scubapro MK25 A700. We give it an overall rating of 4.5 only because it is severely lacking in the warranty it has to offer.Though the Scubapro MK25 A700 goes with the common chrome plated brass construction, the features and design of this regulator puts it in peak performance for regulators. It may be pricey for its brass construction, but the performance more than makes up for it. In performance comparison to the far more expensive Atomic Aquatics T3, there is little reason to drop more than twice the money.The biggest drawback to the Scubapro is in fact, the warranty. Since this regulator has gone through rigorous testing by some pro divers who are impressed with its superior performance, it would stand to reason that the manufacturer would stand behind its quality with a better warranty. We hope that it does someday as the performance and the price begs for a little extra to put customers’ minds at ease with their choice.We believe the pros for the Scubapro MK25 A700 outweighs the lack of warranty. People have used other quality regulators and after using the Scubapro, have completely switched which regulator they use for their primary when diving. It is just that great at delivering air when scuba diving.
