Reach the spots your hand can't. The "Deep Reach" Slider is an 11 cm aluminum extension that screws onto any Pure Frequencies fork — weighted or unweighted — turning it into a tool for your whole back, neck, and shoulders. Press the smooth tip into your trap muscle without bending your wrist. Glide it along your spine. Reach behind your shoulder blade without dislocating anything. Same vibration, same frequency, better access. Solid aluminum, smooth rounded contact tip, screws on in 5 seconds with the included allen key. Built to last a lifetime.
