The digital speed meter™ is the perfect companion for any regular NSD Power®ball model and will allow you to keep an accurate record of your performance on the splendid spheres!
The digital speedmeter™ has 3 unique modes of operation:
1. The real time revolution speed of the rotor.
2. The highest achieved speed in a given session (this will remain in the speed meters memory until either manually cleared or until surpassed by a faster score – it add’s serious fun to your new Powerball and brings out the competitive edge to all as you set about trying to beat either your own high score or that of your colleagues!
3. The Physical strength mode – this counts the number of revolutions made by the rotor in a 30 second period and makes for a worthy stamina challenge to help indicate just how strong you are becoming from using the shiny sphere!
The speed meter simply clips onto the top of any regular NSD Power®ball after first removing the hard plastic cap.
