Diving Nitrox has which potential to provide?
A) longer no-decompression limits, longer repetitive dives
B) shorter decompression limits, shorter repetitive dives
C) longer decompression limits, shorter decompression dives
D) longer no-decompression dives, shorter repetitive dives correct answerslonger no-decompression
limits, longer repetitive dives
The air that we breathe consist mainly of:

To make sure the dive equipment you presently own may be suitable for nitrox, you have to:
A) Check with your SSI Dive Professional if your equipment needs special preparation/modification
B) do nothing, because if its good for air its good for Nitrox
C) do nothing, because it is high quality anyways
D) replace all seats and O-Rings correct answersCheck with your SSI Dive Professional if your equipment
needs special preparation/modification
Is it true, that Nitrox is designed for Ultra Deep diving?
A) No, Nitrox has more restrictive depth limitations than air
B) It doesn't matter if you use Air, Nitrox or any other Gas, both have the same depth limitations
C) Yes, with Nitrox you can dive much deeper than with air
D) Yes, but only in warm water correct answersNo, Nitrox has more restrictive depth limitations than air
