The Saint Artemas nock has been in use in Caid for many years and has been a very reliable nock and APD. There is a model for golf tube arrows and a model for Siloflex arrows. These are NOT interchangeable.

The Saint Artemas nock will not work for crossbow bolts. It also will not work properly for low profile rubber stopper foam (aka Omarad) arrows, due to its weight. Attempts were made to lighten the Saint Artemas nock in order to allow it to work properly for these blunts, but these were deemed too hazardous for the structural integrity of the nock. If you try to use Saint Artemas nocks on a rubber stopper foam tipped arrow, your arrow will sail sideways a few feet after release, and could even swap ends in mid flight! Please remember that Saint Artemas nocks were originally designed only to be used with a tennis ball blunted arrow, and use them accordingly!!
