- Gas Units. Display gas volumes in litres or bar.
- Currency. The currency used to display Gas prices.
- Avg Gas Use. Enter your average rate here.
- Warnings
- Min PPO2. The level below which Decochek will show a warning.
- Max PPO2. The level which Decochek uses to calculate ascents, and above which will show a warning.
- Max END. The Effective Nitrogen Depth above which Decochek will show a warning.
- CCR
- Deco Offset. If in CCR mode, Decochek will reduce the PPO2 by this amount for the purposes of deco calculation.
- CNS Offset. If in CCR mode, Decochek will increase the PPO2 by this amount for the purposes of CNS calculation.
- Graph
- View Gas Changes. Switch the gas bottle display on and off.
- View Grid. Switch the grid on and off.
- View END. Switch the (blue) END display on and off.
- View Ceiling. Switch the (red) ceiling display on and off.
- Drag Bottom. If selected, points at the same depth will be dragged with their neighbours.
- Ascent
- Switchpoint Stops. If selected, will add a 1 minute stop to gas switch points, even if not needed for deco purposes.
- Last Stop. Select the depth of the last deco stop before the surface.
- Bailouts. Calculate a bailout plan whnever creating an ascent.
- Range. Calculate a range plan whnever creating an ascent.
- Conservatism. Add additional conservatism to an ascent. Pushing the slider all the way to the right will pad decompression stops the most.
- Gas Blender
- O2 Cost. The cost of Oxygen per litre.
- He Cost. The cost of Helium per litre.
- Air Cost. The cost of Air topups per litre.
- He first. If checked, will calculate Gas Blending using Helium as the first gas. (If unchecked, Oxygen is used first).
