Which tables should you believe?

[pete340]

However, if for example, you have to use the Wheel to solve a PADI problem - do they also say that you have to use the Imperial or Metric version? Or are there different problems/answers in different parts of the world - i.e an Imperial version and a Metric one?

There are two versions of each question, one Metric and one Imperial.

In my opinion, the Canadian DCIEM dive tables are the best tables on this earth, for all air or equivalent-air nitrox diving. You can probably surf the web for a set. Or you can get them out of one of TDI's tech manuals.

Dr. BRW has new tables out for trimix deco diving. Based on the amount of research that went into them, they are probably the best tables for trimix diving to a max depth of 350 ft. But that is a different story.

DCIEM tables can be purchased at Wlson Diving in Victoria.
