3.2.2. DIVING WITH EAN (NITROX)

3.2.2.1. BEFORE DIVING

This dive computer can be set for diving with standard air only (Air mode) or it can

be set for diving with Enriched Air Nitrox (EAN mode).

If set to the EAN mode, the correct oxygen percentage of the gas in your cylinder

must always be entered into the computer to ensure correct nitrogen and oxygen

calculations. The dive computer adjusts its mathematical nitrogen and oxygen

calculation models according to the entered O

% value (Fig. 3.21.). Calculations

based on Nitrox result in longer no-decompression times and shallower maximum

depths.

DEFAULT NITROX SETTINGS

In the EAN mode, the default setting is for standard air (21% O

). It remains in this

setting until the O

% is adjusted to any other percentage of oxygen (22% - 50%).

If a dive is started within 2 hours Stinger retains this value until the dive series is

finished. If unused, the computer will retain the manually entered value for the selected

oxygen percentage for about two hours, after which it will revert to the default setting

of 21% O

The default setting for maximum oxygen partial pressure is 1.4 bar, however you

are able to set it in the range of 1.2 - 1.6 bar.
