User Manual XC Tracer Maxx
Rev 01 23.2.2020
Introduction
XC Tracer Maxx is a high-precision GPS variometer with a perfectly readable LCD and integrated
collision warning device FLARM. XC Tracer Maxx transmits twice per second the position and also
the estimated flight path for the next 20 seconds. Other FLARM devices in the vicinity can then
draw conclusions about a possible risk of collision risk. In case of a possible collision the
corresponding FLARM device warns the pilot in the aircraft or helicopter. XC Tracer Maxx itself
does not warn of possible collisions with other aircraft.
Many pilots use XC Tracer flight instruments for long XC flights and for competitions. But also for
pilots with little flying experience an XC Tracer Variometer is the perfect choice. The lag-free
indication of lift / sink rate makes it much easier to find and core thermals than when using a
conventional variometer. All essential flight information is displayed on the LCD. In addition, data
such as airspeed, altitude, climb, course etc. can be transmitted to a mobile phone, a tablet or an e-
reader via Bluetooth Low Energy 4.2.
XC Tracer Maxx is also an IGC logger, the IGC files are approved by the FAI for paragliding
competitions. XC Tracer Maxx has a built-in lithium-polymer battery, fully charged the battery is
good for more than 60 hours of continuous operation. The battery is charged via the supplied
Micro USB cable. The device also has a Bluetooth module. Via Bluetooth Low Energy 4.2 data such
as airspeed, altitude, climb, course etc. can be transferred to a mobile phone, tablet or e-reader.

Mounting
XC Tracer Maxx uses data from a 9-DOF IMU (9 Degrees Of Freedom Inertial Measurement Unit),
and from a pressure sensor, to compute the real-time climb rate and altitude, avoiding the
undesired time lag that conventional variometers suffer (due to data filtering). For this reason
mount your XC Tracer Maxx in such a way that it moves as little as possible whilst you’re flying.
It is important that the XC Tracer Maxx moves as little as possible in relation to the harness during
flight. And leave some free space of 4-5cm all around your vario; otherwise the radio performance
may be compromised.
It is therefore important that the XC Tracer Maxx is firmly attached to the cockpit or thigh with the
velcro provided. Mounting on the riser is not ideal.
Switch On/Switch Off
Turn XC Tracer Maxx on by pressing and holding the red button until you hear beep-beep. Next the
battery charge status is indicated by a series of beeps (this feature is described further below). Up
to 2 minutes the system will search for a GPS fix, while only the XC Tracer logo is displayed on the
screen. After a maximum of 2 minutes, the default screen is displayed, even if no GPS fix was found.
Switching off is done in exactly the same way. Press the red button until you hear a "beep-beep",
then release the button and the XC Tracer Maxx switches off.
