20th July 2023

New features

1st June 2023

New features

• Added Freedom HW rev. 4.0 support.

Changes

• Removed apostrophe behind a time (as a minute symbol) for imperial units, to avoid confusion with feet.

16th May 2023

New features

• Set your Diluent or OC mix as default directly when editing the mixture, use checkbox "Def".
• View a TTS2 calculated with current OC mixture, set in "Setup / Preferences / Display / OC Row4/Col3" -> "TTS2".
• Warning when you set GF low > high.

Changes

• Default editor navigation is now a buttons-only / no-tilting needed.
• Button long press time shortened from 1.5s to 1s.
• Polished gas switch notification and improved behavior when diver does not follow the gas switch (see below).
• END calculation switched from "relative narcotic potential" to more common "nitrogen narcotic" or "oxygen and nitrogen narcotic".
  • Set your preference in "Setup / Preferences / User interface / O2 narcotic Yes / No"
• CCR diluents list is ordered by the oxygen content (descending order).
• Renamed "Full log" to "Log size" due to mostly misunderstood function.
  • Default and recommended value is "Log size -> Optimal".
  • The "Log size -> Large" option disables built-in compression and results in extraneous points, and logs taking up unnecessary space in storage medium.
• Buttons-only editor now cycles digits only up to maximum value, no further.

Error corrections

• Fixed "High ppO2" alarm decision factor (bottom Vs. deco).
  • "Max pO2 bottom" threshold is used for default OC mixture and mixtures with fO2 <= default mix.
• Updated Gas switch notification, and Gas Lost algorithm
  • The sole "Gas switch" stop now has its own title, instead of general "Deco stop". Once you arrive at the gas switch depth, you get notification about the switch. If you do not switch within the stop time, then you get another notification at the gas switch stop end. Then, at "Gas Sw. min" + 30 sec the best mix is marked as "lost" and excluded from further calculations. Even when you set "Gas Sw. min" -> "0", then it is 30 seconds after arriving at the stop depth. Remember, you can always switch to the "lost" mixture from dive menu, and thus re-enabling it into the ascent and TTS calculations.
• TTS2
  • TTS2 is available in OC mode only, and serves as a cross-check value for ascent using current mixture only (NO deco mixtures). You can imagine the TTS2 as a value calculated always with "Setup / Decompression / Ascent gas" -> "Current", that is only difference from the standart TTS. Setup in "Setup / Preferences / Display / OC Row4/Col3" -> "TTS2".

17th November 2021

• User configurable date format, see "Setup / Miscellaneous / Date format"
• CCR Diluent ppO2 added to "technical screen", top right, next to stack time.
• Added "universal" water salinity according to EN13319 (Setup / Preferences / Salinity).
• Selectable lower button function - cycle dive screens or display off (Setup / Preferences / User interface / Lower bttn.).
• Optional no-tilt editor, using buttons only (Setup / Preferences / User interface / Navigation).
• Lower button long press in menu will step one line up (backwards).
• Fixed unwanted behavior with all OC mixtures disabled.
• Fixed technical screen refresh in surface mode.
• Fixed misleading display of "Deco stop", instead of "Gas switch".
• Fixed "End pressure" rounding error when using imperial system.
• Fixed dive log profile display below 327.68m.

20th May 2021

• Fixed TTS glitch, which displayed BO TTS immediately after switching mixtures. After a few seconds TTS went back to normal GF.

26th June 2020

• Fixed USB drive error with too much short dives

17th June 2020

• Fixed No-Fly time.

• Fixed USB connection mode, for Freedoms with 300+ dive logs.
