The design is a collaboration between Ernest Langdon and John M. from the LA Sheriff's SEB team. The 2" dots are there to privide fundamental accuracy drills that can be run at closer distances.

This can be used to provide a larger aiming area for speed work at closer distances as well as the large aiming area for Mfg: National Target
