Minimum required training to dive to 30m (100ft) with Padi

[BoltSnap]

wouldn't the lessons be better reinforced by planning the dive, diving the plan and executing the new skills? For example going through the need to locate an analyser, calibrate the analyser, analyse the gas, mark the tin, then diving within the "hard" depth constraints that nitrox brings. Not forgetting that you should see the benefit of longer dive times within that depth constraint.

This ^^^^^

The classroom only Nitrox course/certification is least useful if it doesn't have practical experience especially as related to real dive planning including repetitive dives and dealing with imprecise gas mixes.


(Unusual for me to agree with @Wibble )
