Hi,

I agree with you Phil, but unfortunately diving organisations take lots of time to change or modify a course and since instructors are teaching everyday and students are diving everyday then the best thing an instructor can do is to explain to his/her student a bit more on how to stay "Safe" and one way to do that is of course by eliminating any problem factors in advance. BUT, if diving instructors and those who are involved in diving organisations on high profile would make a stand to increase the safety standard within courses then of course it would be the best solution for everyone.

Best Regards. Wael

Hi Wael,

I agree entirely, but it's a question of how. I think (and it is just my opinion) that instructors should:

a) encourage their clients to take a mix course (such as IANTD ART) with their Mod 1. As only IANTD do this, I think, it would encourage the other agencies to think about their standards, as they would lose students
b) put pressure on their agencies to allow an arrangement such as ART, or to actually extend the Mod 1 standards to include mix

One thought - there may be a safety disbenefit to including mix in Mod 1. Most people agree that narcosis is more of an issue on CCR than on SCR or OC (I can confirm that it is :-(. If all teaching is on mix, then students won't be exposed to that and won't become aware of it. If they then dive air dil when they can't get mix, they may be more prone to being caught out by narcosis.

Cheers,
