The transition between the two functions is done simply by holding down the primer part of the cap (with a pencil or any other similar object, even your finger) for 7 seconds. A double flash will indicate the transition between modes.
The Dual Function back cap can be used to replace any cap on all SureStrike™ cartridges and can be used with all available caliber adapters.
All replacement back caps have a microprocessor controlled primer activating the SureStrike™ laser cartridge. By using exchangeable back caps, you can decide which functionality is most suitable for your training. This feature makes SureStrike™ the most versatile dry fire training system available today.
