    Have had the Tusa Duo Air for almost a year and about 75 dives. Very pleased with it. Easy to distinguish buttons - I especially like this design when compared with some of the other button configurations out there, good breather. I recommend practicing with it to become familiar and comfortable accessing it and actually breathing with it if the need should arise. Jaw fatigue could be an issue for longer term use by its very nature, but being an alternate this really is a non issue.
    The Duo Air was easy to install and have liked it well enough to buy another one for a new Zeagle BC I recently purchased. Felt it was a very good value after the research I did.

    For the price this is a good 2nd stage air. The regulator is not very comfortable or ergonomic to use, however it is an emergency device and you will hopefully never have to breath on it for extended periods of time.

    It is slightly on the heavy side, but you hardly notice when your busy diving.

    Overall I would recommend this for a diver on a budget.

    Comments about TUSA Duo-Air Alternate Combo Inflator:

    Much, MUCH easier to assemble than I imagined, having read other reviews. Especially since I was installing it on a non-TUSA BCD. It fit my Scubapro perfectly.

    Looks sturdy, if a little clunky.

      Comments about TUSA Duo-Air Alternate Combo Inflator:

      Keep in mind there are two different connector sizes that Leisure Pro doesn't seem to want to list in their specifications. This item was a Tusa, like my BCD, but had a larger size connector. Very strange.

      But, it came with a new hose, so that wasn't a big deal except that I wasn't able to use a new soundmaker that used the smaller connector.

      Other than that problem it worked fine. My inflator hose is quite long, so it was pretty easy to breath off the device. But, it did try to twist in my mouth, so I would only want to use it in an emergency.

      The normal inflation and deflation operations worked just fine.

          Comments about TUSA Duo-Air Alternate Combo Inflator:

          The IR-3 breathes very easy for an alternate. Eliminating another hose is always good. Also, save yourself some cash...it's almost identical to the more expensive Air-2.

            This alternate air/octopus can't beat beat for price and performance. I've used it on my TUSA Platina BC and it works perfectly, it breathes easy, there are no freeflow problems, convenient location on BC, very easy installation, including shortened quick detach LP hose, so that doesn't stick up past your shoulder. I couldn't be happier, especially since it is less than half the price of other manufacturer's models.
