[ No decompression limits ]

The range of time when it is unnecessary to stop to decompress while surfacing

from a dive is determined by the depth and time of the dive. These values are

referred to as "No Decompression Limits." Use these as estimates when diving.

No Decompression Limits, based on the American Navy Diving Manual (1985), are

printed on the band of this watch. (Some models may not have this chart.)

DEPTH.m N.D.TIME

Example: If the diver is at 21

meters for 50 minutes or less,

then it is OK to surface without

stopping to decompress.

Other functions

[ Register ring ]

Use the register ring to measure elapsed time.

EXIT

Elapsed time is 10 minutes

Before diving, rotate the register

ring to line up the mark with the

minute hand. Elapsed time is then

indicated by the position of the

minute hand on the register ring.

Example: In the diagram at left the

minute hand is 10 minutes past the

mark, indicating that 10 minutes

has elapsed.

= NOTE =

The register ring may only be turned

counter-clockwise (this helps prevent

unwanted movement). Do not attempt

to force it to turn clockwise.

Caution:The no decompression limit

is different depending on body condi-

tion, or personal differences. Please

use the no decompression limits on

this watch as a guide line.

When a dive requires no decompres-

sion limits make sure you follow a spe-

cialized divers manual.
