What would be the best choice for a stage bottle with tech1 in mind (aluminium, obviously). I can't see any particular requirements on the GUE site for tech1 and even tech2 only requires bottles of 30cu.ft or greater. Is there any reason to get a bottle larger than 40cu.ft.? Are there any other requirements I need to know other than material?
Hi Barry! (and thanks again for DIR-F course!!)
Was just talking here with my Tech1/Cave1 trained buddy and he said to get 80cuft tank,
that's what they used on their T1 course. He has 21M MOD stickers on it.
Other requirements. Dive, dive, dive, have fun, have fun, have fun.Train, train, train and ascents/decents need to be top notch ;-)
