Used in competition ATA trap shooting, the interrupter will randomly interrupt the side-to-side pattern of oscillation for a completely random target presentation that is impossible to anticipate. The interrupter will conserve battery usage by not allowing the ATA/wobble base to run for more than 6 seconds. This item can be added to the ATA and wobble bases. The wobble base can use just 1 interrupter or add 2 interrupters for more random presentations. The interrupter is already included in our commercial series ATA, wobble and tri-axes wobble traps.
