This transmitter in radio mode is compatible with any Receiver on the market, although if you want to receive the exact point where it is with GPS locations, you will have to have the COLOMBICULTURA Microfind GPS Receiver.
Can you imagine not having to go around looking for the best radio telemetry signal points and go directly where the location marks you.
In addition, it only weighs 3 grams, and its dimensions are so micro that they can hardly be seen placed on the tail of your pigeon, being able to hold it like any other transmitter or with a tail clip or with a bridle attachment.
And as if that were not enough, the battery of this transmitter that does not use batteries but is served with a charger is unsurpassed, it connects and disconnects with a magnetic switch or with the transmitter's own charging base.
Available in 433 and 434 Mhz frequency.
