He shows good bouyancy control. Not as easy as it looks. All of this is a step up from the ‘basic’ diver course.

How is this advanced? The only concept that was remotely challenging seemed to be shut down procedure.

When in water, it weighs nothing. However, when you try to climb aboard a boat after a dive, you feel as heavy as a car.

the smaller tank might be “enriched air” (ie, over 21% mix) – for accelerated deco, OR it might be “oxygen” (100%) – again for deco (but limited MOD is 6m for 100%).

the two tanks on his back is just a twin-set – doesnt mean he’s diving on helium! A helium mix would mean he’s diving on a trimix which means he can go deeper for longer – but thats all.

thats for deep dives

the smaller tank is enriched oxygen, it is used for coming up

the two tanks in the back is a mix with helium in order to negate the effects of what i believe is called in english nitrogen narcosis

Those are steel tanks. (even the deco cylinders) You would need no lead.

My instructor said this to me when i finished my NAUI OW. Now you learned how to dive, but now you must learn to dive” I think that was a good thing to say
