6.3. Gauge Mode
Gauge Mode turns the Tern into a simple depth and
time display (a�k�a� a bottom timer)�
Since decompression tissues are not tracked in Gauge
Mode, changing to or from Gauge Mode resets the
deco tissues�
`
By default, gauge mode is displayed in “Big” layout
with the Max depth and Stopwatch shown in the info
row�
Change to the Standard layout configuration for
additional on screen information and increased
customizability�
Learn about home screen customization options on
page 20�
While on the surface, the MAX and AVG values display
the maximum and average depth of the last dive�
The AVG depth displayed on the surface is for the
entire dive, regardless of whether the reset average
depth option was used� The dive log also records the
average depth for the entire dive�
Gauge Mode Features:
• Resettable average depth
• Stopwatch
(These features are available in all modes)
