Here is an article I came across....
"We recommend AVID for many reasons. First, the scanner reads all the chips that are sold in the United States. That includes The Home Again (which is actually made by a company called Destron), all other Destron chips including the original 400 MHz Destron chip (now these chips are 125 Mhz), the InfoPet #1, and all the AVID chips. The "universal" readers that were all programmed by AVID also ID a European Chip called Trovan that was sold for a very short time in the U.S. It is not legally sold now due to patent infringements |
