  • Micro Transmitter - leg mount

This tiny transmitter is the "Ideal Tail Mount" for all sized birds. It weighs only 3.5 grams with the battery yet is a medium range flat design putting only 1/3 the weight on a single tail feather.

Unlike other transmitters using very small batteries, the new Micro doesn't fade out or die in low temperature situations.

It is perfect for small specialty birds: Merlins, small hybrids, sharp-shinned hawks and other extremely small raptors. You can order it with a 'fine' or a 'medium' gauge antenna, depending on intended use.

The Micro also contains the magnetic 'tap on/tap off' switch, a half-length 7.5 or 9 inch antenna with incredible power and efficiency. Each unit is burned in for five days and Enviro-tested tested from +150F down to -40F prior to shipping. Available frequencies: 216, 217, 218, 219, as well as the extremely powerful new UHF frequencies (433 and 434).


The Micro is our smallest transmitter design, weighing only 3.5 grams with the tiny 1225 3v lithium coin-cell battery installed. Yet its range exceeds that of most transmitters twice or three times its size and weight.

In this image, Terry installs the especially small tail piece has been made just for the Micro transmitter.

The matching tail-piece installation tool is used to quickly install the tail piece from above on to the deck feather of a Merlin. The process is quick and simple causing much less strees to the bird.


Using the very small and light lithium coin cells, the Micro transmitter is engineered to radiate the most power possible while squeezing the battery's reserves most efficiently. At room temperature, the Micro will transmit continuously for 30 hours of normal use (30 one hour flights, one month) before telling you to change the battery with a double beep every tenth pulse. After that, the battery runs about 70 more hours for a total time of about 100 hours. Using the Mag switch to Tap on and off for each flight, this might translate into one or two months of normal use per battery change, while always maintaining a safety margin of three days to look for a lost bird.

You can leave your battery in the Micro for up to six months. The transmitter keeps track of cumulative transmission time to estimate remaining battery life, even when not transmitting.


A Micro with a new battery will operate in extreme cold, down to -40C (-40F) due to it's unique design using tiny capacitors to store up the charge even when a battery's current begins to drop due to extreme cold.

But as coin cell batteries run through their life cycle, they lose some of their ability to provide current to run the transmitter in very low temps, so that after 48 hours of normal use the same battery may not work below -18C (0F). This only means that if you are about to fly in very cold temps, and there's a chance your bird may be lost overnight when the temperature drops, you should always use a new battery.
