what is this bubble trick?

Where? Just name the center you took the class from, don't dime your instructor.

Says who? PADI still teaches 60 ft per min.

LOL! I wasn't aware of that, but I believe you. Consider the source. Just when I think I've lost all respect for them, I lose a little more.

Wow, ok then. Color me uninformed, I too thought that had changed. Haven't read anything PADI in quite awhile.

 

[Firefyter]

Never mind....

SDI also says no faster then 60ft a minute

That's the bubble mask, keeping the hand tight to your forehead exhale enough air to create an airspace around your eyes so you can view your guage/buddy/whatever. Search the bubble mask, its an interesting, maybe fanciful concept for us youngins but lots of old-timers swear they learned it in OW...

Are you serious? Oh we have *got* to try this....

OK - still not getting it though (sorry, I'm slow about these things sometimes). If I am wearing my mask, why can't I see my gauge or buddy without blowing the bubble? I'm blowing air into my mask, like clearing it, but without actually letting the air escape?

 

[BrianS]

No, your hand would be above your mask, so you are creating a air bubble in front of your mask. Possibly giving you a much better field of view.

Yeah, they invested too much money in the RDP, which was tested with 60ft/min and none of the hot-shots at the mother ship seem to be willing to annihilate that investment... It would appear to me that they're giving sales of the RDP priority over following best practices.
