The RT is designed around the reliable 1/3N lithium battery which gives it it's unique shape and size. With its longer battery life and powerful signal, it was developed to be a primary leg mount for larger shortwings and longwings (18oz birds and up). The RT+ was the first of a new generation of transmitters with a short, safe, half-length antenna, yet still puts out more power than others still using long ones. It is also ideal as a secondary (backup) transmitter to the PowerMax tail mount. Features are now found in the RT+ never before available in a falconry transmitter.

Each unit is burned-in for five days and Enviro-tested tested from +150F down to -40F prior to shipping.

Originally developed as the "ideal tail-mount," this transmitter has a flat, tail-hugging design with an antenna so short it doesn't extend beyond the deck feathers of the larger birds. Moreover, it's designed so it can be left on the bird and simply turned on or off with the tap of a magnet for daily use.

The PowerMax is now lower in overall weight, puts out even more power yet runs even longer on the same 1632 lithium battery! It incorporates a new "fuel-gauge" type of low battery indicator that uses both a timer and internal voltage sensor. Accumulated run-time is now approximately 72 hours (instead of just 30) with another 4-5 days left to search after the double-beep.

It's particularly ideal for those considering the BackPack Harness. Birds as small as a Merlin have carried the PowerMax using the new TrackPack Mount!

This tiny transmitter is now the "Ideal Tail Mount" for all sized birds. It weighs only 3.5 grams with the battery yet is a high-power, long range design putting 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, 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-inch antenna with improved power and efficiency over the old Micro.
