Dive Setup
You can customize the dive settings based on your needs. Not all settings are applicable for all dive modes. You
can also edit the settings before you start a dive.
Hold MENU, and select Dive Setup.
Gases: Sets the gas blends used in the gas dive modes (Setting Up Your Breathing Gases, page6). You can
have up to twelve gases for each gas dive mode.
Dive Network & Air Integration: Allows you to pair Descent transceivers and configure the data screens (Air
Integration, page8).
Conservatism: Sets the level of conservatism for decompression calculations. Higher conservatism provides a
shorter bottom time and a longer ascent time. The Custom option allows you to set a custom gradient factor.
NOTE: Make sure you understand gradient factors before entering a custom level of conservatism.
Water Type: Allows you to select the water type.
PO2: Sets the partial pressure of oxygen (PO2) thresholds, in bar, for the maximum operating depth (MOD),
decompression, warnings, and critical alerts (Setting PO2 Thresholds, page7).
Scuba Alerts: Allows you to set custom alerts for gas dives (Custom Dive Alerts, page6).
Apnea Alerts: Allows you to set custom alerts for apnea dives (Custom Dive Alerts, page6).
Display Settings: Allows you to enable or disable Big Numbers mode and customize the data screens for each
dive mode (Dive Data Screens, page11).
Safety Stop: Allows you to change the safety stop duration.
Last Deco Stop: Allows you to set the depth of the final decompression stop.
End Dive Delay
Allows you to set the length of time before the device ends and saves a dive after surfacing.
CCR Setpoints: Allows you to set high and low PO2 setpoints for closed-circuit rebreather (CCR) dives (Setting
CCR Setpoints, page8).
Dive Shortcuts: Allows you to assign button shortcuts for use during dives.
Advanced Settings: Allows you to customize advanced dive mode settings (Dive Mode Advanced Settings,
page5).
Dive Mode Advanced Settings
Hold MENU, and select Dive Setup > Advanced Settings.
Double Tap to Scroll: Allows you to double tap the device to scroll through the dive data screens. If you notice
accidental scrolling, you can use the Sensitivity option to adjust the responsiveness.
UP Key: Allows you to enable or disable the UP button during dive activities to prevent inadvertent button
presses.
Silent Diving: Allows you to disable all tones and vibrations for alerts during dive activities.
Heart Rate: Allows you to enable or disable a heart rate monitor for dives. The Stored Strap Data option allows
you to enable a chest heart rate monitor, such as the HRM-Pro
™
series accessory, that stores heart rate data
with the dive. You can view chest heart rate monitor data in the Garmin Dive
™
app after you complete the dive.
Compass: Allows you to calibrate and set the north reference of the dive compass (Calibrating the Compass
Manually, page116).
No-Fly Time: Allows you to set the no-fly countdown timer mode (No-Fly Time, page8).
Satellites: Sets the satellite system to use for dive entry and exit locations for each dive mode (Satellite Settings,
page66).
Units: Sets the distance, depth, and tank pressure units of measure for diving.
Deco Lockout: Allows you to disable the decompression lockout feature. This feature prevents single-gas,
multi-gas, and CCR dives for 24 hours if you violate a decompression ceiling for more than three minutes.
NOTE: You can still disable the decompression lockout feature after violating a decompression ceiling.
