The virtual distance football can let you know how far it was thrown with an accuracy that's supposedly within 1 yard and shows the distance in it's LCD readout. Its sensor tells how far the ball has traveled by measuring the ball's impact at the end of its flight.
The main backdrop here is that the this isn't a regulation-sized football - - - at just 6 inches long it's 5 inches short of the regulation tip-to-tip length of a the regulation NFL ball, but weighs about an ounce more than the NFL-standard 14- to 15-ounces.
