Technology advances in Dog Trackers
When Dogmaster first came into being we had about 4 categories of product and no dog tracking systems. We sold dog training collars and bark control collars primarily for sheep & cattle farmers. We soon found out that the sons of farmers (and sometimes daughters) often were feral pig hunters. Not only was it a sport for the hunters, but it helped the farmers by thinning out the numbers of wild pigs on farming properties. Feral pigs can make an incredible mess of watering holes and areas near dams. Feral pigs can be predators of young lambs, I have even heard a farmer witness a boar attack on a pregnant sheep.
We soon started looking for dog trackers to sell, and it wasnt long before we put our first order into the manufacturer in Finland. The technology back then was RDF or Radio Direction Finding. Basically a radio transmitter located on a collar was placed on a dog and every few seconds the collar transmitted a beep via radio signal. The hunter would scan the receiver toward the horizon and wherever they heard the beep, was the location of the dog. However there was no map showing creeks, mountains and other obsticles, there was also no distance to dog.
Then along comes Garmin with the Garmin Astro (insert star wars music when Darth Vader walks into a scene). All our old technology RDF tracking systems start collecting dust on our warehouse shelves. GPS collars were here to stay and the old RDF was gone.
