Stay tuned for future information as it becomes available... This product & concept is still currently going through testing and development. These are not available for sale anywhere in the world, and as such, cannot be purchased at this point in time. This product will really enhance our ability to further understand exactly how pigeons navigate using "REAL TIME TRACKING DATA", as well as allow us to train more effectively on race courses. I forsee there being many different useful applications this can be integrated with, in the near future. What makes this product completely different than all of the other current products on the market is... it is (NOT) a data logger. With this product in development, "REAL TIME GPS TRACKING" will be a game changer. To receive updates regarding this devices development, please visit this page on a regular basis. The photos you see below are my actual birds that I own that will be tested over the next few months, using this device. The birds ages range from 2005 through 2018.
