Why every diver should take a regulator course!

[Blue Quaker]

What myth? I used to own Poseidons and have rebuilt them. At one point we had a serious issue with getting parts... hey, just like a Saab. We all like different things, and I got rid of them because I didn't like them.

The "myth" that I was referring to was that the Poseidon regs are overly complicated and difficult to service... They are not. I never questioned whether or not you could service them, or suggested that everyone should dive with them. Use whatever reg you feel comfortable with for the diving that you do. I use Poseidon regs because they work best for me in the environment that I dive in.
The parts problem was caused by a lawsuit between the US distributor and HQ in Sweden, who refused to sell him inventory while the suit was in place. It may have been exacerbated when I bought Joe S. parts inventory so I could keep my regs and my customers regs in shape​

Thanks for all the great responses and additional information...really useful.

I got the tools and books that @The Chairman recommended in the course. I'm ready for some practice on my own. Think I'll start with a regulator I'm not using much...

I'm interested to read up on using the magnehelic in the books and form my own opinions with a bit more practice.
Look forward to spending another afternoon with @The Chairman next trip to FL and continue learning the subtleties. That gives me another idea...maybe my local regulator tech would let me spend an afternoon shadowing him.
