It appears that would a "no", but pretty impressive resume,nonetheless.
Andy Davis | Sidemount Technical Wreck Diving Instructor | Philippines
I've been offered cave instructor training, but passed on it because:
1. No caves near me to enable the opportunity to dive frequently enough (i.e. near-daily) to achieve the level of proficiency that I consider a minimum.
2. My interest is wrecks, and has been for 27 years. I'm busy doing that to a high level as a daily job.
3. I don't have small balls, so I don't need to collect trivial cards for the bragging rights online. I leave that to the pot-bellied desk-dwellers whose diving doesn't speak for itself.
I've also been invited on 'proper' exploratory cave expeditions in SE Asia, by highly reputable exploratory-grade cavers who I've taught (i.e. sidemount, technical wreck or mixed gas). As per my earlier comments in this thread, I believe that the cave and wreck environments demand specific education - so I refused. Although I felt very honoured and complimented to be asked.
Obviously, I haven't trained with NSS-CDS because:
1. I'm not American.
2. I don't live or dive in America.
3. I have no plans to live or dive in America.
4. NSS-CDS is an American national organisation.
I thought it was common knowledge that I am British and live in the Philippines...
What I HAVE done is:
1. Trained NSS-CDS qualified divers and instructors, particularly in sidemount and wrecks.
2. Taken training, or done mutual skill exchange, with very high level cave instructors from a myriad of American, European and Australasian cave organizations.
