    Good

    Slob knobs are a triumph of practicality over snobbery

    PS my CCR instructor dived Alpinist but I don't. Two of my GUE instructors dived without a slob knobs and my Tec instructor for OC dived a CCR but If I dive twinset OC I dive a slob knob

    Diveing without a slob knob put far greater pressure on buddy skills buddy diveing and "team work"

    If you don't use a slob knob chances are you will have less gas to paly with and will need your buddy more. SO Slob knobs are ideal for the way I dive which is solo with another diver for company who I expect to let me down in an emergency and if they help that's nice but I dot rely on it.

    SO qualifie your opinion.

    Manual shut down are ONLY good for people A: who find them easy and B: for people who dive in skilled disciplined teams.

    However, the answer is not clear cut.

    If your disability precludes you from delivering and developing optimal techniques, or teaching from first hand experience, then yes.

    Otherwise no.

    How do you route a slob knob? I have never seen one in action.

    I'd go further and say that the negativity towards a slob knob creates an environment where those that should use them don't.
    The champions of shutdowns would say that is irrelevant as the solution is practice, but the reality is far from that ideal.

    The optimist in me would say that divers should strive towards being able to do it and only use a knob if unable to do it through injury
    or through personal choice.

    The realist says if you don't do the training it's safer to use a slob-knob then assume that somehow you'll manage when the brown
    stuff hits.

    no good for you they are only for slobs. Unless you are a slob

    the actual routing of the knob depends on the diver, but you need to have access to it with the absolute minimum of fuss, some have over the shoulder some under the arm but all should be in front imo.

    Ha! I recognise that torch

    As for shutdowns, I doubt anyone would disagree that the majority of divers can do it, subject to a correct kit setup.

    If you have a physical injury that prevents it, of course you find a workaround (whether thats slob knobs, or something else). The most important thing is to know that you can do a timely shutdown (which means regular practise, for me that means at the start of every dive I check i can twiddle any taps in water).

    Classic,

    new member comes on asking to buy a bit of kit and within 5 mins is told its a waste, that he needs more training and (by implication) is a sh1t diver.

    What a great welcome.

    I wonder if somewhere there is a forum that suggests people go on TDF and post stuff that will get a reaction. Much like Mumsnet is for here
    Rememeber anything you read on the internet was probably written by some guy sitting at home in his underpants! Including this !!
