The S8 is a stand-alone variometer with target speed, GPS input and PDA/PNA output (two-seater option).

The Variometer S8 from LXNAV is a stand-alone digital vario with target speed sensor and final glide computer - With GPS input and PDA/PNA interface - The sunlight-readable 2.5" display is very easy to read in all lighting conditions - Three pushbuttons and two rotary switches with pushbutton function are used to set all parameters and for menu selection. - Integrated inertial platform (MEMS technology) - Flarm displays (when Flarm is connected as a GPS source) - Flight log function - Second display with pushbuttons and rotary switches can be connected for two-seater operation

Functions

• Extremely bright 2.25″ QVGA color display, readable under all lighting conditions with adjustable backlighting
• Three pushbuttons and two rotary switches with pushbutton function for setting all parameters
• GPS input (bidirectional) in IGC standard (RJ45 connection)
• PDA interface (bidirectional) for communication and power supply of the PDA
• Integrated inertial platform (MEMS technology), 3-axis G-meter, 4-axis gyro for intertial vario, wind calculation (with compass) and AHRS
• Wind calculation approx. 1 x per second with compass module
• 100Hz data rate for short response times of the vario
• TE compensation possible via nozzle or electronically
• Pre-installed polars for almost all gliders
• Flight log function
• Flarm displays (if Flarm is connected as GPS source)
• Flarmanradar (when Flarm is connected as GPS source)
• Lots of additional information, such as mean climb, upwind climb, net, speed,...
• Customizable audio settings
• Audio equalizer
• Voice output
• Target speed display

Some useful values can also be read on the varioscale, e.g. average climb (red diamond), set McCready value (blue arrow) and climb over the updraft (green T). Comparing these three values makes it easier to assess the current climb and the McCready value.
