Just when you thought that Powerball couldn't get any better... After years of careful planning, we have succeeded in developing a revolutionary new Autostart 280hz Powerball and now with a battery-free speedometer/counter. A completely standalone product, no string is required to start the gyro - simply pull back the rotor and spin!

Offering the same superlative build quality as the other Powerballs in the range the 280Hz Autostart has the added advantage of being truly portable and can be easily operated by anybody - no strings, no thumb start, no flick start... just wind it back and let go for a perfect start every time!

This latest 280Hz model can be used for strength, training, rehabilitation and fitness applications as well as being an excellent addition to the training regime of any musician.
