AVOIDING AND MANAGING DECOMPRESSION
The Pro Plus is a sophisticated instrument designed with capabilities that go
beyond the range of recreational diving with compressed air. It will help you
to avoid and, if necessary, manage decompression.
TISSUE LOADING BAR GRAPH™
The Tissue Loading Bar Graph™ offers you a convenient way to consistently
monitor how close you are coming to the No Decompression Limit. As you use
the Pro Plus and become familiar with the Tissue Loading Bar Graph, you will
notice that it displays fewer segments for shorter dive times and shallower
depths. Use this feature to adjust conservatism to your diving needs.
Use the yellow Caution (C.Z.) Zone (Fig. 59a) as a visual reference to
place a wider margin of protection between you and the No Decom-
pression Limit.
Oceanic suggests keeping the Tissue Loading Bar Graph in the green
No Decompression (NO DECO) zone during all of your dives, and that
it be in the green when leaving the water.
