Question 13

Normally, how often do you call out depths to the diving supervisor during decent? What about during ascent?

Answer 13

Depths ever 10fsw on decent and eery 5fsw on ascent

Question 14

In your own words; define stage depth

Answer 14

The Pneumo reading taken when the diver are on the state or on the bottom prior to leaving bottom. Use it to compute distance and travel time to 1st stop or surface

Question 15

In your own words; define Max Depth as it applies to a console operator

Answer 15

It’s the deepest depth obtained by the diver plus the Pneumofathometer correction factor

Answer 16

0-100 FSW ——– +1 fsw
101-200 FSW ——+2 fsw
201-300 FSW —–+ 4 fsw
301-400 FSW —–+ 7 fsw
