Read ranges vary from 6 to 20 inches depending upon specifications. AVID is the most cross-compatible microchip system on the market. You can purchase the MiniTracker II, that reads ONLY the AVID chip. Or you can purchase one of our other models that will detect and read several brands of chips. The price of the chips is the same.
Microchips go into the animal by way of standard injection.
Those familiar with the delivery systems for vaccines and regular shots will have no problem injecting the chip. My pet already has an AVID chip. No, unless you are a veterinarian. There are two reasons for this. No better, no worse.
