We have used the GPS Tracker TK 102-2 for all of our stratoflights successfully. This device is extremely reliable and transmits the GPS data to a few meters. Therefore you just have to insert a SIM-card, call the number and a few seconds later, you will receive the coordinates and a GoogleMaps link via SMS. The great advantage of the TK 102-2: In case of the battery freezes, it may stop working, but after it unfreezes, it will continue to track its position automatically. Other devices have to be activated manually after freezing.
Our tip: It is possible to use two GPS Tracker simultaneously which run with different SIM-Cards. Thereby you can double-safe your equipment because especially for the tracking you should play safe.
ATTENTION: Many forgeries of the GPS Tracker TK 102 are available on the internet! We only offer high-quality products that we use in our own missions!
