What to do while waiting for my first post-OW dives

[dmaziuk]

This has always confused me (as a non-nitrox diver). Why don't they have you dive with Nitrox as part of the course? Shouldn't seeing how it differs be part of the training?

It doesn't differ for practical purposes.

All you'll see is longer NDL on your computer, but as training dives aren't normally done to NDL, you won't be able to do anything with that.
