The rubber at target is worn by penetrating projectiles. This will eventually cause noise to enter the soundproof measuring chamber inside the target. Such wear normally occurs in the center of the target. To ease maintenance and lower maintenance cost the target is fitted with a rubber band and a foam sheet insert that is covering the centre of the target.

This rubber band must cover the hole, pre-cut or later cut out, of the target rubber skin. The rubber band is intended to be rotated sideways to eliminate the wear at centre. When rubber band is rotatd, the foam sheet should also be replaced.

How often this maintenance is needed depends on calibres in use, bullet shapes, shooting distance and shooter skills (grouping). As a rule of thumb, for this target model, we recommend following intervals based on shooting distance:
