  1. Minorescu

    Great gift for sailors
    My dad loves sailing so I got him this for one of his trips.
    Not only did he use it to scuba dive in the middle of the ocean, he also used it to fix the engine while in the middle of nowhere. This can make trips better or be a life saver!

    Work in progress.
    The product is not perfect but has potential.
    The main issue is that, if you fill it from the air tank using adapter, you can fill it up only once.
    Next time if you fill it from the same tank, you can only fill 3/4. Then next time you can only fill half.
    I think it is related to pressure in the air tank. Only a full air tank will fill it up in full. So if you took an air tank with you and thinking you’re going to reuse it to fill it up, forget it. It won’t work.
    The other issue is that it does not give you 15 min downtime as advertised. I tried with full tank, calm, in shallow water and I get max 10 min.
