    "My question is the same question I asked the forum a few years ago.......is there an argument to do a check on your alternate air source once you are UNDER the water, or as WOZ suggested back then that you should do a really hard "suck Test" before turning on yr air to check for leaks/ bad seals etc. This is the second time I have gone to someones alternate (the first one was a training exercise so no great shakes) and found myself breathing water......both Alternates breathed perfectly well at the surface during the buddy checks but not when they were really needed. The last thing you need is to be in a spiralling situation and going and getting someones alternate only to find it doesn't work, that could be the beginning of a really nasty incident.

    So do you think this should become a part of most recreational divers buddy check.....apart from WOZ telling me this method I have not heard anyone else mention it and have certainly not seen anyone actually do it !!!"

    BSAC teaches the 'breathe down' test i.e. turn gas off and breathe down to test for leaks during kit assembly in the second sheltered water lesson for Ocean Divers (OS2). Don't see it done much in practice though.
    I do that . To show students what it looks like on the gauge and so they can feel the DV getting tighter. But then I have read the manual .....

    Excellent post and some very valid points but it also seems to me that diving with someone you know and trust means knowing and trusting that they will have serviced/maintained/checked their kit properly. That's part of what buddy diving involves.

    If I could possibly use it, I'm going to check it immediately prior to the dive.

    Whether that's mine or my buddies.

    Trust has no place where certainty can be gained very quickly.

    Remember what you're gambling with.

    Spot on - other people's complacency with this and failing to analyse gases never ceases to amaze me
