TDI vs PADI TecRec

[boulderjohn]

I cant speak much at all about either course. I do recall,,, the difference that seamed to matter,,, delt with having to be associated with a shop to teach. So hypothetically ,,, you can teach PADI on your own but you cant with SSI for example. I have heard that if a shop is not a (IE... nauii) shop you cant give a nauii card. This prevents a shop from having all agencies being taught in one shop i guess. Each agency has it requirements concerning instructor permission to teach. Roumor only..... Padi is the easiest, and has been for a long time and hence PADI is seen everywhere. I recall this issue ccoing up when i was persuing a solo cert and the shop was not an SDI shop.

The question was PADI technical diving as compared to TDI technical diving. It had nothing to do with SSI or SDI.

The whole PADI idea of making students go past 150 feet on air seems pretty absurd at this date.

To each their own. To me the whole idea that trimix would be requested to dive past 45 m seems overly conservative.

Which should have been the end of your reply.

I've seen good divers and train wrecks pop out the end of both with the same ticket

PADI doesn't "make you" as someone said before. In reality, going down on air, especially with nitrox deco, to 50m (usually 47-48 for tec 50) is reality not that big of the deal. And once you are ready for dives deeper than 50, trimix 65 is their next gate.

Nothing like reviving an 8+yo zombie thread for Halloween

You'll have to get to Trimix either way, and the material gets covered in different chunks in the two paths, but once you get to Trimix it has all evened out.
The PADI materials are superior, but TDI can be more tuned to your specific needs. One consideration might be what you want to do after DM....if you are going to go the instructor route, with PADI, then the PADI classes might be more helpful. But since your instructor can do both, and he is already selected, it really doesn't make all that much difference right now. You can get going faster with TDI, but when it is all done, you are in the same place with the possible need for the PADI credential to help you on an instructor path.

In addition, since your instructor is credentialed with both agencies, he can give you both cards by teaching one super-course. He just has to meet the standards for both agencies.
