As I suspected, I cannot scan my Avid chip. I checked an unimplanted chip I had laying around to be sure. The scanner just can't make any sense of it's output, at all. It's very proprietary, which Avid is presently being sued for.
Luckily I've got a couple of scannable chips on the way. I'll make sure that they operate along side an avid chip without interferance problems and then I get chip #2 stuck in my back. These things are not the size of a grain of rice like they say they are. I took a chip out of an implanter and my eyes went huge. It's almost an inch long. Fun fun fun *wags* I love this stuff.
Scanning range seems to be a good 4-5 inches. This is great. I might get away with putting the scanner in the back of the seat behind all the padding, perhaps even adhered to the seat back itself. That would be perfect.
