Had a Nitrox fill in Capers yesterday. When we measured the mix, the guy referred to a table and, for 32%, told me that the MOD was 40m. I always dive Nitrox, so have a good idea on MOD and know that 32% = 34m give or take, so queried it. The boss turned up and told me that the table was fine and, on enquiry, found that they were using 1.6 rather than 1.4. Whilst I recognise that 1.6 is for use when helping your buddy when he is in trouble, I've never seen it used at a fill station - I guess there could be an argument that you need to know how far down you can go to save your buddy before you kill yourself! All this is slightly irrelevant for Capers that has a maximum depth of 20m, but a tank filled there can be used elsewhere - what do you think?
