Data Fields

NOTE: Not all data fields are available for all activity types. Some data fields appear in more than one category on the dive computer.

Name

Description

Ascent Rate

The current rate of ascent toward the surface.

Average Depth

The average depth descended during a dive.

Avg Temperature

The average temperature during the dive.

Battery Percentage

The percentage of the battery power remaining.

Battery, Time, & Temp.

The percentage of the battery power remaining, the time of day based on your current location and time settings (format, time zone, daylight saving time), and the temperature of the air.

Compass

A visual representation of the direction in which the device is pointing.

Compass Heading

The direction you are moving based on the compass.

Conservatism

The level of conservatism for decompression calculations.

CNS

Your current central nervous system (CNS) oxygen toxicity percentage.

Current Gas PO2

The partial pressure of oxygen (PO2) of the current gas.

Maximum Depth

The maximum depth descended during a dive.

Max Temperature

The maximum temperature during the activity.

Min Temperature

The minimum temperature during the activity.

N2/He%

The nitrogen/helium tissue loading percentage.

NDL ↑3M / NDL ↑10FT

Your No Decompression Limit (NDL) time if you ascend 3 m (10 ft.) from your current depth.

NDL ↓3M / NDL ↓10FT

Your NDL time if you descend 3 m (10 ft.) from your current depth.

NDL Δ 3M / NDL Δ 10FT

Your NDL time if you ascend or descend 3 m (10 ft.) from your current depth.

None

This is a blank data field.

OTU

Your current oxygen toxicity units (OTU).

Raw Ceiling

The unrounded depth the diver should not ascend past.

Stopwatch

The stopwatch time for the current dive.

Sunrise

The time of sunrise based on your GPS position.

Sunset

The time of sunset based on your GPS position.

Surface Gradient Factor

The expected gradient factor if the diver were to instantaneously surface.

Temperature

The temperature of the water. Your body temperature affects the temperature sensor.

Time of Day

The time of day based on your current location and time settings (format, time zone, daylight saving time).

Time of Day (Seconds)

The time of day including seconds.

Time to Surface

The amount of time required to safely ascend to the surface, including decompression stops.

Tissue Graph (GF)

A bar chart displaying simulated values for nitrogen and helium in the body, with the y-axis of the field adjusted to your conservatism.

Tissue Graph (Raw)

A bar chart displaying simulated values for nitrogen and helium in the body.

TTS @ +5 min.

The amount of time required to safely ascend to the surface if you remain at your current depth for five minutes.

TTS Δ +5 min.

The difference between the amount of time required to safely ascend to the surface, and the amount of time required to safely ascend to the surface if you remain at your current depth for five minutes.
