Nitrox Divers - in 'ere please

[bottlefish]

I mark my tanks up with my name, O2 percentage to nearest integer and the MOD, Target Operating Depth as well if I'm not swapping straight on to it at the optimum depth. Markings are done on the neck, for me to see and horizontally across the bottom for my team to see. I also mark the reg with mix amd MOD as well, just for that last check when doing my gas switch.

There's no way my fill station would mark each tank so extensively, so that's good enough for me... adding a decimal place in to the mix just takes up extra space.

I put it on the analisis lable as what it is to one decimal place. The analisis lable is small and insignificant and only for checking before loading up the tank for use.

If the tank is to be idenstified and used in the water its marked in big bog off letters that are perminant.


So as an example my 50% Nitrox bottle is clearley marked 50% and has a 21M MOD on it as well. On the top it has a little bit of gaffa tape that reads 52.4% which is what it analised to last time and is signed by me.
