technical diving international (tdi)

hi i have some questions about the tdi organisation if that is ok. thanks in advance for your time to answer my questions.....


1) what is the difference between tdi and tdi middle east?

2) why does the tdi middle east manuals have a different cover to the other tdi ones?

3) on my tdi deco procedures card it says tdi middle east and on my extended range one it says td with the normal logo but i did them in the same plac, why?

4) why have the wall certs changed? my adv nitrox one is diferet to the deco proc and the exten range.

5) why does jayne l mayer no longer hand sign the wall certs?

6) the instructor number isnot on ther certs, does this matter?


thanks and sorry for what you might call "silly questions", i am just curious.
