XC Tracer Mini 4 Solar GPS-Vario


These units will be delivered to us in October 2021.  They are not currently in stock.  However, we are listing them as in stock so customers can purchase them now, and get in the back order line up to have them shipped as soon as they arrive.  Your unit will be delivered in the order it was purchased.

There is a new XC Tracer available soon, and it will replace the XC Tracer Mini III GPS. We aren’t quite sure on what the upgrades are at this point with the Mini IV.  We are waiting to hear, and will post those details here when they are released.  We expect to have the new Mini 4’s in stock by mid to late February 2021. Anyone ordering the Mini 4 now here will be certain to receive a Mini 4 when our first batch of instruments arrive. The text below applies to the Mini III.  We are certain the Mini IV will have all these great features at a minimum.

The XC Tracer Mini III GPS is a solar variometer with GPS and BLE, simple and performant. It may weigh only 34 grams but it has more than one trick up its sleeve!


Conventional variometers have the major flaw of having a lag between the actual climb/sink rate and the audio feedback. XC Tracer Mini III GPS gives a lag free audio feedback due to the use of an accelerometer combined with the barometer. This allows to be way more efficient in thermals, especially in weak conditions. It is possible to customize the audio feedback sound to your taste here!


XC Tracer Mini III GPS does log an IGC and and KML file in parallel. The IGC files are accepted by F.A.I. for paragliding competitions, and you can look at your track in Google Earth in simply double clicking on a KML file.

There is a new XC Tracer, XC Tracer Mini IV GPS. It’s basically an XC Tracer Mini III GPS with USB-C. The MIVG has the same sensors as the XC Tracer Maxx. What’s new with the MIVG is that data is only transmitted via BLE in flight.

Please note that there is a worldwide shortage of electronic components. Therefore no reliable delivery times can be given. Delivery of ordered Varios will be in the order of received orders.

The XC Tracer Mini GPS has been used by more than 50% of the XAlps pilots?


Don’t be surprised not to have to charge it for a full season! There is a lithium polymer battery built in, when fully charged the battery has enough energy to power XC Tracer Mini IV GPS for more than 20h hours without sunshine. But since the battery gets charged when it’s exposed to sunlight (even when the device is turned off) by the solar cell you get an almost infinite autonomy! In case it should be necessary you can also charge the battery via the USB-C cable that got shipped with your vario.


The Bluetooth BLE (Bluetooth Low Energy) 4.0 module built in allows you to connect the Mini IV GPS to your favorite app (see list here) on your Android /iOS / e-reader device. A connection over USB is also possible, but it is recommended to use BLE whenever possible. You can configure the BLE strings that you want to send to your phone, tablet or e-reader using a simple configuration file.


One button and that’s all. You’ll use it to switch on / switch off the device and to choose the volume from 0 (silent) to 3 (loud). Configuration is made via an intuitive text file. If you struggle with the updates or just to access to the XC Tracer memory check out this page.


We highly recommend you the software LogFly! Intuitive and compatible with XC Tracer. Don’t bother counting your hours anymore. It does everything by itself and provides many interesting statistics.
