Summary

Product Introduction

Surface Interval Mode

Side Contacts

Dive Mode Operation

Remaining Time (NDC)

No-Decompression time remaining at current depth.

Current Depth

Shows the diver's current depth in feet or meters.

Maximum Depth

Tracks the deepest depth reached during the current dive.

Bottom Time

Records the duration of the dive at current depth.

Water Temperature

Displays the water temperature in degrees Fahrenheit or Celsius.

Ascent Rate Bar Graph

Variable-by-Depth Ascent Rate

Ascent rate alarm adjusts based on diver's current depth.

Fixed Ascent Rate

Ascent rate alarm remains constant regardless of depth.

Decompression Mode

Ceiling

Depth the diver must not ascend above during decompression stops.

Decompression Time (DEC)

Displays required decompression time at current stop or total stop time.

Bottom Time

Total time spent at depth during the current dive.

Current Depth

Shows the diver's current depth in feet or meters.
