Operation Manual

TLBG (TISSUE LOADING BAR GRAPH™)

The TLBG offers you a convenient way to consistently monitor how close you are coming to

the No Decompression Limit. As you use your dive computer and become familiar with the

TLBG, 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. Select models also

feature a Setting that allows a Conservative Factor to be added that reduces No Decom-

pression Times.

Use the No Deco Caution Zone as a visual reference to place a wider

margin of protection between you and the No Deco Limit.

Oceanic suggests that the TLBG should always be in the No Decompression zone when

leaving the water.

MULTIPLE TISSUE TRACKING

An Oceanic PDC tracks 12 tissue compartments with halftimes ranging from 5 to 480 min-

utes. The TLBG displays the controlling compartment, the one important at that time.

Think of the TLBG as 12 separate transparent displays laid on top of one another. The tis-

sue compartment that has ﬁlled up fastest is the only one the diver can see from the top.

At any particular point, one tissue compartment may be absorbing nitrogen, while another

that was previously higher may be off-gassing.

NOTE: This feature is the basis of multilevel diving, one of the most

important contributions that an Oceanic PDC offers you.
