+The Tec Settings offer extra columns to show, settings for more graphs and

-You can set the following options:
  - Depth:	Your diving depth in Meters or Feet
  - Pressure:	The pressure of your tank(s) in Bar/Ato or PSI (Pressure Square Inch)
  - Volume:	The volume of your tank(s) in Liter or CuFt (Cubic Feet) (At sea-level pressure)
  - Temperature:	The temperature of the water in Celsius or Fahrenheit
  - Weight:	The weight of your weight system in kg or lbs

- - Show OTU:	Shows the OTU of your dive (Oxygen Toxicity Units)
  - Show Weight: Shows the total weight carried
  - Show Suit:   Shows the suit you were wearing

+ - Show MOD		Show the Maximum Operating Depth of the used gasmix (for the given max. ppO2, default 1.6)
