| A few years ago I was going on a cave diving trip to Switzerland and didn't have time to get my bottles tested. So I made up a few "Tested to BS 1234" stickers, stuck an IANTD logo on them and put them on my bottles. Worked perfectly and I never got a second look. The sticker paper works well but it does come off after a bit.
For gas markings, I don't want to permanently dedicate a bottle to a certain mix so I use transparent gaffer tape and a waterproof marker, works just as good and easily changed. |
