AC2 is a keeper

2nd stage XS2 well... meh. But the AC2 first stage... what a perfect and well thought out design! I will use this regulator for many years to come and service it myself. Few parts, IP adjustment ring.. servicing this 1st stage is child's play. But the second stage is just crap. Hard to even remove the front cover without having to purchase their special tool and removing the stupid plastic pin. Hard pass. Rating: AC2: 10 stars / XS2 -6 stars

Recommended Regulator

This was the first regulator I bought, so I could stop renting all the gear each dive trip. It's still working great almost 5 years later. I serviced it yearly, but it never failed me.

Excellent regulator and octopus combo. Would recommend replacing the mouth piece, due to the original mouth piece being a little to small. Great for the price.

Loud and cheap

It is good for an inexpensive reg, but it does vibrate loudly while exhaling. It sounds like Darth Vader with asthma. But it’s inexpensive enough to overlook.

No need to spend big bucks

I've3 been using this set for as long as I've been diving. I've had it down to 131' and 42°F where my buddies high end environmentally sealed reg freeflowed. This one didn't - it breathed fine and easy. Best of all it's simple to do your own service. The service manual is on-line and parts kits are only about $10-$15.

Not Recommended!!!

Second stage leaks air during negative pressure test and leaks water when submerged. when descending head first or swimming inverted water enters second stage at dangerous levels. Not safe at any depth...

Great Choice for a new diver

By Ron

My son and I both have an XS-2 regulator set. I have about 80+ dives on mine and it has never failed me yet. It breathes easy and is lightweight and comfortable. It may not have as many bells & whistles as some other regulators but it you want your own regulator and can't afford to spend a ton of money, this is a good regulator for you. I highly recommend it. It is easy to maintain and can be serviced at most reputable dive shops. I have used it in tropical climates (Bahamas, Jamaica, H...

Cressi XS2/AC2 Piston Regulator

The XS2/AC2 Regulator is a reliable 1st stage regulator designed for non-balanced flow-by-piston use. It is a great choice for beginner divers or as a stage bottle regulator system. The 1st stage regulator is made of marine grade chromed brass which ensures durability and longevity. It has one high-pressure port and four low-pressure ports. The regulator features a conical filter with a larger surface area, providing better air flow characteristics.

The XS2 Compact Second-Stage housing is made of durable, non-corrosive hi-tech polymers and has a dependable downstream demand valve mechanism. The flow of air is channeled to the mouthpiece through injection, which creates a venturi effect, enhancing the performance of the regulator. Additionally, the 2nd stage comes with a flow deviator that adjusts the Venturi effect and has a dive/pre-dive adjustment function. The regulator is equipped with a comfortable silicone mouthpiece.

The XS2 Compact AC2 Regulator has a weight of 35 oz (994g) with the hose and comes with an owner's manual. The regulator is certified to EN250/2000 standards and is manufactured in Italy.
