So, you ignore any questions from people (who wanted to help you), yet you demand an answer to your question, huh?
Gotta love that!

If you don't wanna 'talk' to anyone, I suggest you learn how to use google.
 
Thank you, but there is no dept limit to the standard .Diving Classes only at the Trimix classes etc.
I see you didn't actually read the documents I linked to.

Yes I have, and I have read the standards for CMAS 3 and they do not write a dept limit, they only refer to the national recommendations.

If I were you, I'd demand a refund for my tuition fee. Because it seems as if your reading abilities are somewhat lacking.

Wow what a nice comment, is must be very difficult for you to write "nice" to other people. If you see my question I ‘am referring to deep dives around 40-50 meters on air not below. And there is no depth limit for CMAS 3, unless they mean with "any sport Diving activity" you can dive to any depth you feel.

Look at the Extended Range course content from TDI,

The limit is normally dictated by the sanity of the diver or the 1.4ppo, where it will be good that you take a camera with you because you will not remember much of what you saw at that depth.
 
TDI teach diving on air to 55m on air and below that training is on Trimix
 
I wonder how having a DM on the surface will help anything going on below 40m though....
