A new, innovative touch screen allows you to switch between devices with a simple double click. A built-in position sensor and strong magnets allow you to set, mount or secure the PU2 - the PU2 always knows where it is and will adjust the screen accordingly. It's not just a good controller for your tattoo equipment - it's just a very good and very simple PU2!
