Transponder so your wife can tell where you are any where in the world. Stay away from your local whore house or she will come down and beat the tank up on your GSA. Do you know how expensive those tanks are?
Only problem is you have to remove the chipmunk scraper to install it so it is easy to tell your being tracked.
