Designed as a classic insertion nock, the illuminated nock fits all shafts with an inner diameter of 0.297 inch - 0.302 inch (7.54-7.67mm) and does not have to be glued in. The nock is made of transparent plastic to ensure maximum brightness and to make the illumination visible in red, yellow, green or blue in all directions.
When the bolt is inserted into the crossbow, the illumination is activated by a small switch in the centre of the nock when it comes into contact with the string. To deactivate the illumination after the shot or at the end of training, there is an opening in the side of the nock. Simply push the coloured element inside the nock upwards with the help of the enclosed screwdriver.
