To use an airsoft gun with the target unit select Airsoft for the shot mode in the app. Special target paper is needed when using airsoft. We hope to eventually provide packets of these targets, but in the meantime you can make your own.
Take a NRA target and spray the back with contact glue. Press a sheet of regular aluminum foil to the back of the target being sure it is smooth and fully glued down. Trim the excess and use the target just like a regular target. The foil will make sure the holes punched by the airsoft pellet stay open allowing the box to detect the hit.
