Suunto Zoop Novo has the following dive modes:
By default, Air mode is activated when you enter dive mode. You can change which mode is activated or turn dive mode off under the general settings.
To change dive modes:
Each dive mode has its own settings which you need to adjust while in the given mode.
To modify dive mode settings:
Some settings cannot be changed until five (5) minutes have elapsed after the dive.
Air mode is for diving with regular air and has the following settings:
Nitrox mode is for diving with oxygen-enriched gas mixtures.
Diving with nitrox allows you to increase bottom times or reduce the risk of decompression illness. However, when the gas mix is altered or depth increased, the oxygen partial pressure is generally increased. Suunto Zoop Novo provides you with information to adjust your dive and stay within safe limits.
Nitrox mode has the following settings
In Nitrox mode, both the percentage of oxygen in your tank and the oxygen partial pressure limit must be entered into Suunto Zoop Novo.
This ensures correct nitrogen and oxygen calculations and the correct maximum operating depth (MOD), which is based on your entered values.
The default oxygen percentage (O2%) setting is 21% (air) and oxygen partial pressure (PO2) setting is 1.4 bar (20 psi).
To modify gas mix settings:
If the oxygen content of a mix is set to 22% or above, the setting value remains until changed. It does not automatically revert back to 21%.
With Gauge mode, you can use Suunto Zoop Novo as a bottom timer.
The timer in the center of the display shows dive time in minutes and seconds and activates at the start of the dive. The total running dive time, in minutes, is in the lower right corner.
The timer in the center of the display can be used as a stopwatch by pressingduring the dive.
Pressingresets the main timer and adds a bookmark to the dive log. The previously-timed interval is displayed below the main timer.
Gauge mode has the following settings
Gauge mode is a bottom timer only and thus includes no decompression information or calculations.
With Free mode, Suunto Zoop Novo can be used as a freediving instrument. The dive time is indicated in minutes and seconds in the center of the display.
The free dive starts at 1.2 m (4 ft) and ends when your depth is less than 0.9 m (3 ft).
Free mode has the following settings:
You can define up to five independent depth notifications for freediving, for example, to alert you to start free falling or mouth filling. Each notification has a defined depth and can be turned on or off.
When you reach the notification depth, the backlight blinks and the low priority audible alarm sounds.
To define depth notifications:
While freediving, you can use the surface countdown timer to help you prepare yourself for you next dive. Suunto Zoop Novo starts the countdown as soon as you reach 1.2 m (4 ft).
To set the surface countdown timer:
