We've been putting RFID chips in dogs we adopt-out for 20 years or more. The chips have been great for getting a lost dog back to its family many, many times.
I have one installed on every cue I own. My buddy became a retail dealer with snagg and always has them on hand. Very easy to install. Snagg site easy to register each cue as well and it even takes pics of your cues.
We are working on an LD Snagg chip... just so you know that the snag chip causes a lot of squirt due to the microbore and epoxy. We will have our new chip ready for usage by 4/1/16.
