LASER. The Bocce Ball Laser measuring device is next-level measuring. Measuring to the 1000th decimal point, you'll know exactly which ball is closest to the pallino. L: 4.25", W: 1.75', H: 1" Weight: 3.63 ounces. Measuring up to 60 meters/131 ft., you can use it as a stand-alone unit or you can use it on a swivel that moves 360 degrees - up, down, and to the side. Batteries included. To get the best measurement, place the laser/cup in front of the larger ball (see photo) and shoot the laser to the pallino. Alternatively, you can also place the laser/cup on top of the pallino (see photo) and shoot the laser to the larger ball (s). You decide which approach is best.
