This is the official WFTF Target Testing device used at the Field Target World Championships. Each device is calibrated to give the same impact force as an air rifle with 16J muzzle energy striking a steel target at 55 yards.
For details of how to use the device and a demonstration please visit the open source project page : WFTF Target Tester Project Page
If you have your own 3D printer, or access to one you can make your own target tester by downloading the source files on the project page. If you would prefer to have one made and calibrated for you, you can order one from here. Please be aware that the demand for these devices is high at the moment and my capacity to make them is limited. Each device is printed over an elapsed period of 3 days and after that it takes some time to assemble and test the devices.
Please be patient, I’m making them as fast as I’m able to.
Head of Marshalling ( WFTF )
