Cold or Arduous Dives-1<br />

Dives<br />

Rule: For cold or arduous dives, use the next longer<br />

duration for the dive schedule<br />

– Example: Schedule for a 70’/30 dive that is cold or arduous is<br />

70’/35<br />

If you cannot use the next longer duration because it<br />

places the diver into decompression, use the next less<br />

available bottom time<br />

– Example: Maximum no-deco bottom time allowed for a cold or<br />

arduous dive to 70 feet is 45 minutes and the RNT would be<br />

figured as if the dive was made for the next greater bottom time<br />

(i.e. 50 mins)
