    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.
