I cannot understand why you would want to do Tec training while in Cozumel. That totally misses the mark of Cozumel diving.
My husband is a certified tech diver and when we go to Cozumel he never even considers it... Cozumel is all about rec limits for mind blowing reefs, and some crazy wild rides in current with great fishlife.
Are you serious? Cozumel being what it is has some amazing walls and topography where the depth available can open lots of options for those trained. For those of us that are used to doing deco in cold and dark waters with limited visibility, doing deco in Cozumel or any tropical destination is an absolute treat.
It is a great place to conduct deep diving and do tech training. Just a few reasons off the top of my head:
-Relatively benign and predictable conditions for training (obviously it's drift diving so there is current, so drifting deco)
-Warm water (no drysuit, heavy undergarments, no argon bottle)
-Excellent visibility (great for training, watching students and exploration)
-Depth available for any level of training from deco procedures to advaned trimix and beyond
-Marine life encounters below recreational depths (often reef sharks, sometimes hammerheads at Maracaibo, Colombia, Punta Sur Sur)
-Some really beautiful structures below 150' (black coral, overhangs, interesting topography)
-Extended dive times and runtimes
With that being said, Cozumel is really not a tech diver destination although there are many that do it there, myself included. While there are certainly lots of opportunities for it; There really aren't many shops or instructors there that cater to it. You're right that the majority of diving and things you want to see are in recreational depths but I don't believe it misses the mark of Cozumel diving. It adds considerable value. It still amazes me while places like Thailand and Red Sea have capitalized on this and large tech diving communities, Cozumel really doesn't have a huge tech community. Perhaps lack of wrecks...
Thanks for the input. I am sure that TDI and NAUI are fine alternatives. But, I need to only consider shops / instructors that can issue the PADI TEC 40 cert. I need to do this on Cozumel as that is where we are staying.
Off top of my head I don't know any specific instructors on the island that teach the PADI TEC curriculum but I will ask around. The majority I see are TDI instructors. I'm assuming you need PADI because you run a PADI dive shop and are looking to perhaps do PADI Tec for some requirements or to eventually offer it at your shop?
Just throwing that out there for those asking why you aren't considering TDI and other agencies. If not, you may be able to cross over in future.
You may want to contact Don at Deep Exposure Dive Center. While I believe he runs TDI technical courses, he may be able to run PADI Tec courses as well or at least know of someone who does. His shop in my opinion is one of the better equipped for technical diving on island. He has his own compressor, a booster and pumps trimix and oxygen. Most shops on the island have to go through Meridiano 87 for this. I've never taken any training from them but his shop is one of the better equipped to handle gas for technical divers on the island.
German Yanez is also a great instructor. Although he caters to mostly cave diving. He also teaches TDI equivalent of PADI Tec 40/45.
