In the past, more heat was produced by using more and more abrasive fabrics. The abrasive fabrics currently being used wear off the pebble. This causes flatter ice and increases the difficulty in making quality shots. EQualizer technology will keep the heat produced close to the ice where it is needed, providing many benefits over other brush-heads. EQualizer brush-heads feature less abrasive fabrics leading to less ice damage and the reduced friction requires less effort to sweep.
