Cressi XS2 AC2

Scuba diving for many is an addictive activity that many people fall in love with quickly. For those that are serious about scuba it is important that invest time and effort, as well as money, in selecting your gear. This holds true for one of the most important parts of your scuba gear; the dive regulator. When making such an investment it is important for find high-quality products that will perform as it is supposed to keeping you safe under water.

We know how important finding the right regulator is, and in this article we will review one of the most popular regulators on the market for under $200; The Cressi XS2/AC2. We will examine its features and specs, as well as compare it against some comparable products to see how it stacks up.

What Is the Cressi XS2/AC2 Regulator?

The Cressi XS2/AC2 is a simple and very inexpensive regulator manufactured by Cressi Sub in Italy. The first stage is a balanced flow-by piston design that is very common with most first stages on the market. This design performs well and ensures natural breathing at virtually any tank pressure. However, the Cressi XS2/AC2 is not the best design for divers that routinely dive in very cold water. For cold water divers, a diaphragm type first stage is more reliable in cold water and less likely to freeze open. For most divers however a balanced piston design, like the Cressi XS2/AC2 is a good choice.

The Cressi XS2/AC2 regulator is constructed with durable materials design for many trouble-free dives. The first stage is constructed from chrome-plated brass that is both lightweight and durable. The first stage features 1 high pressure port and 4 low pressure ports for gauges and different low pressure attachments. The Cressi XS2/AC2 uses a conical filter which enhances air flow, and is preferred by most divers.

The Cressi XS2/AC2 second stage is constructed with advanced polymers that are both lightweight and rugged. The second stage features a downstream demand valve mechanism which is also very common with second stages on the market. The downstream demand valve mechanism ensures easy breathing and helps eliminate freeflows. The second stage utilizes the venture effect for enhanced effortless breathing. A pre-dive/post dive switch is included which will help eliminate free flow when the mouthpiece is out of the divers mouth as long as the pre-dive setting is selected.

The Cressi XS2/AC2 regulator comes with a comfortable silicone mouthpiece that reduces jaw fatigue and enhances breathing. The Cressi XS2/AC2 regulator only weighs 35 ounces with the hose, and is certified to EN250/2000 standards
