Have 40 dives on it, mostly boat diving where I usually come in with 1000-1200psi left. But last week's trip 5 shore dives I noticed the reg during it's last 1000-500psi made me suck real hard to get the air out of it. My other shore dive exits were fine if I had 1000psi+ left so I never noticed this before.

          I have never had my own regulator, just those rented from dive shops. I love this reg and love having my own equipment. This is a great reg and I am very happy with my purchase after the first several uses.

          Comments about Cressi XS2/AC2 Piston Regulator:

          Really easy to put together, some free flow issues we will watch for frequency. Would like a longer second stage hose. The price for the unit and the functionality make it a great starter unit. We used it in Woahink lake as a test run and found it funtioned in cold water perfectly outside the freeflow issues.

          Comments about Cressi XS2/AC2 Piston Regulator:

          I bought this reg because it was on sale. I do solo diving and I made my own pony system for safety and this is the reg I use it for and I feel confident this reg will get me out of any situation. It free-flowed heavily on my first dive with it, but after that, no issues. For more advanced diving, I would defintely suggest spending the money and getting a better reg. This is good for occasional useage such as if it's just for a pony system.

          Questions & Answers Powered by TurnTo®

          Questions about this item:

          Erik F  Is it good for cold water diving? I had an aqualung reg freeze up on my buddy in water around 48 degrees. I'm debating to get this or a similar reg or the cold water kit for the aqualung I already have. Any recommendations?
          Frank L  Not recommended for cold water below 50 degrees. Most manufacturers recommend using an environmentally sealed first stage below 50 degrees. Contact us directly and we can suggest some for you, or check out the Cressi MC9- SC: http://www.leisurepro.com/p-csbre9sc/cressi-ellipse-balanced-mc9-sc-regulator.
          Erik F  That's a very nice regulator, but I just need something simple. It's for a 19 cu. ft. pony bottle that hopefully never gets used, but needs to be sold and reliable or there's no point in having a pony. Would it be better to get a cold water kit for my backup reg and just get a new backup reg? Most of my equipment is mares. Would the Rover 2 handle cold water?
          Shopper  Is it Nitrox compatible?
          LeisurePro S  Yes this regulator is nitrox compatable.
