Swix Evo Pro Edge tuner is a high precision electrical side edge tuner, developed to restore, maintain and to give the edge a World Cup finish. The EVO is very easy to operate, due to its ergonomically design, quick disc change and easy angle set-up. A key is also that the long lasting diamond disc is independent from the user pressure, as it is attached to a spring, making it impossible to mistakenly change the radius of the ski. The EVO is equipped with a high quality diamond disc, and by using a diamond material, the edge becomes harder and more durable. This ensures enhanced performance, especially on ice and artificially snow. The EVO comes with a FINE polishing disc included. As spare parts COARSE, MEDIUM and FINE are available. 220 Volt.
