    Comments about Aquatec Duo Alert:

    I had high hopes for this product and after testing it on 10 dives, the best noise I could get out of the underwater Duo Alert was similar to blowing a raspberry at someone, underwater. My dive buddy couldn't hear it all unless he was within a meter.

    The topsideDuo Alert was no better. Beyond 2 meters the noise it made fell into the background noise. Our conclusion is that the Duo Alert is quieter than blowing the whistle attached to your BC.

    I sent mine back for a refund.

    Questions about this item:

    Shopper  Why Did You Choose This?
    MATIAS I  both alerts on the same device
    Benedict L  Which version works with the scubapro X-tek 30lb donut wing?
    PETER C  You want the one with the matching fitting, but, I see your dilema: there is no way to select the fitting type on the website. I'd call. By the way, the item is great, underwater it's not too loud, on the surface, it's effective.
    Benedict L  Which type works with "scubapro X-TEK Donut 30lb wing"?
    ERIC V  As this is an inline emergency notifier mounted on your reserve second stage it is set up to work with scubapros air2.
