“If you lose it, you can find it.”

Wildlife Materials, Inc., (WMI) has been manufacturing high quality telemetry-based tracking transmitters and receivers since 1970. We started out building equipment for studying and locating wildlife species around the world. Our tracking equipment has been seen on many nationally televised nature shows. 

We also build tracking collars for sport dog recovery for valuable hunting dogs throughout the United States and abroad.  

Model Airplane and Rocket Telemetry

Decades ago, we were approached by Jim Walston of Smyrna, Georgia who convinced us the Free Flight model airplane enthusiasts needed a tracking system to locate aircraft that has been lost. The model rocketry market soon followed suit. Jim became the lone distributor for our products to those markets until his retirement in 2016.

We are happy to announce we will continue Jim’s legacy of providing the highest quality telemetry-based tracking equipment to help fliers quickly recover their downed aircraft. You can now talk directly with the manufacturer.

This website offers an extensive list of traditional models of transmitters and receivers hand-built for the model aviator. If you don’t find what you need we can build you a custom transmitter for your plane or rocket. Our motto is “if you lose it, you can find it.”

We appreciate your business.
