Who knows standards NAUI ice diving?
When under the ice are two divers - each diver must have a signal line, or as in PADI - one for two?
"All divers must be equipped with a minimum of two wholly redundant cylinders, with a minimum of 80 cubic feet (2265 liters) for primary cylinder and 19 cubic feet (538 liters) for "bailout bottle."
The main cylinder 80 cubic feet - he should have V-valve or H-valve and two regulators? Or sufficient one regulator on the primary cylinder and one regulator on the bailout bottle?
What is the minimum thickness of the ice?
