Transceiver Settings; Selecting Transceivers To View During A Dive; Selecting The Gas Consumption Rate Metric - Garmin DESCENT MK3 Series Owner's Manual

Transceiver Settings

You can customize the settings for paired transceivers prior to a dive.
On the paired Descent watch, hold MENU, select Dive Setup > Dive Network & Air Integration > Transmitters,
and select a transceiver.
Status: Enables a connection to the transceiver, and shows the current connection status.
Placement: Sets the transceiver location as either your own tank or that of another diver.
Public Tank Name: Allows you to associate a name with your transceiver, which will be visible to your dive
group.
NOTE: If you customize this name, another option appears in the list to clear the name.
Nickname: Allows you to associate a nickname with another user's transceiver, which will be visible on your dive
data screens.
NOTE: If you customize this name, another option appears in the list to clear the name.
Identify: Plays a tone on the selected paired transceiver. This helps you to identify the transceiver without
needing to look at the transceiver ID printed on the transceiver housing.
Working Pressure: Sets how much pressure the tank has when full. This value is used to determine the upper
end of the pressure gauge, and to calculate respiratory minute volume (RMV) for tanks using psi units.
Reserve Pressure: Sets the threshold values for reserve pressure and critical pressure alerts to appear on the
watch.
Volume: Allows you to enter the air volume of the tank. You can use the Reset Volume option if you move the
transceiver to a different size tank.
NOTE: This value is required to calculate volumetric surface air consumption (SAC) and respiratory minute
volume (RMV)

(Selecting the Gas Consumption Rate Metric,

SAC/RMV/ATR: Enables the transceiver to be included in volumetric surface air consumption (SAC), respiratory
minute volume (RMV), and air time remaining (ATR) estimates
Calculations, page 11).
Set Transmit Power: Allows you to adjust the power setting if your transceiver is losing connection with the
paired watch underwater.
About: Displays the transceiver ID, software version, and battery status.
Remove: Allows you to remove a paired transceiver.

Selecting Transceivers to View During a Dive

You can view two paired transceivers at-a-glance on the primary dive data screen. You can customize which
paired transceivers appear on the screen. By default, the first and second transceivers that you pair appear

3 Select an option.
NOTE: The watch can estimate volumetric surface air consumption (SAC) or respiratory minute volume
(RMV) only if the air volume of the tank is entered in the watch
can estimate pressure-based surface air consumption (PSAC) with or without the air volume of the tank.
