DTS Gas Guru

- Mixer: the top-up gas and the second bank are now "Custom mix", with oxygen AND helium, so you can top up from a trimix bank or a storage cylinder of mix. - Pinch to zoom the MOD, Density and Mixer tables. Pinch back or double-tap to return. - Mix Library: ships with six working mixes; the add-a-mix form is the first row; "Suitable at" lists every gas you can breathe at the depth; each row's MOD follows that mix's own limits; a mix you delete stays deleted. - Clearer MOD labels: the Density tool and cylinder labels state the ppO2 and END each depth was worked out at. - SCR: choose CMF or PSCR before any figure is shown. - Settings: Reset restores every setting; water temperature stops at 33 °C everywhere; new mixes start on your own limits. - The quick start turns its page with a swipe. - "SM / TWINS" on the cylinder pickers. - Many smaller wording and display fixes. Always analyse every cylinder before you breathe from it.
