    A question about tail weights on a doubles rig

    Hi there, Not so long ago I did a doubles primer training day with a GUE instructor. One of the many things I learned was about my trim. He fixed my trim by attaching a 2.5kg tail weight to my rig that I kept nice and flat, brilliant. I asked him if I could buy the weight off...

    A Weighty Problem

    I was looking at a post I wrote on another thread in which I said that I dive with 4kg on my weight belt when diving doubles and a hefty 13kg on my weight belt when I dive a single (I'm a bit of a floater). For exposure, I wear a 1 piece 5mm semi-dry I'm thinking 13kg is waaay too much so am...

    hogarthian rig and a HP transmitter

    . I thought the whole idea of a hog rig was to eliminate as many points of failure as possible. I like having the backup of a mechanical SPG (on my left post) to the transmitter I have on the right post when it comes to reading gas left in my tank

    Stupid question without notice... double tanks

    Nice one guys thanks for your advice. Even if I had the isolation valve closed I could have simply switched to the reserve regulator, but by this stage I was getting a bit worked up about it and decided that getting worked up about stuff is unsafe and it was better to be safe than sorry, so I...
