ALTITUDE DIVING

The mathematical model within the DataPlus accounts for the reduced No

Decompression time available at higher elevations based on NOAA (National

Oceanic and Atmospheric Administration) guidelines. When diving in high

altitude lakes or rivers from 2,000 to 14,000 feet (610 to 4,268 meters), the

DataPlus will adjust automatically, providing corrected depth and reduced No

Decompression times.

Also, when above 2,000 feet (610 meters), depth calibration of the unit is auto-

matically changed to read in feet of freshwater rather than feet of seawater. The

DataPlus will not activate at altitudes above 14,000 feet (4,268 meters).

More about altitude diving and NOAA guidelines is presented on page 77 in the

Reference section.

WARNING: Until it has shut itself off, you must not use the

DataPlus at a different altitude than the altitude where it was

originally activated. Doing so will result in an error equal to the

difference in barometric pressure, and possibly a false dive mode

with erroneous data.
