Smallest Size, Lightest Weight

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.

Micro Sized Tail-Pieces and Installation Tool to Match

The small tail feather piece is used with the matching tail-piece installation tool to quickly install the tail piece onto the deck feather of your bird. The process is quick and simple causing very little stress to the bird.

Most Power Possible from Tiny Battery

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 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.

Antenna Options

Both the standard (thin) and heavy (thick) antennas are available for the Micro, made with the tiny aluminum ferrule attachment.

Leg or Tail Mount Option

Two body designs are available: the leg mount case with a tiny Bewit attachment loop at the top and a smooth back, and the tail mount case that has three tiny posts on the back to hold the tail spring and make it field replaceable.

Can Also Be Used on Larger Birds

Although designed for use on the very smallest of birds, the Micro can be used as a tail mount for larger birds, offering minimal weight without a significant sacrifice in power.

Works in Cold Temperatures

With a new battery, the Micro will operate down to extreme cold temperatures (-40F). We recommend using a new battery every day when flying in extreme cold temperatures.

A Great New Option for Licensed HAMs

For American customers with a HAM License, the transmitter can be programmed with your Call Sign, which will be broadcast in Morse Code at startup and once every ten minutes as required by law.

Service details

Using the Mag switch to tap on and off for each flight, the Micro 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.
