toward a location in the path of a golf club swung adjacent the housing; a light
reception device supported by the housing and configured to receive reference light
emitted from the light emission device and reflected from the swung golf club;
and discrimination circuitry coupled with the light reception device and configured
to distinguish the reflected reference light received from the light emission device
from incidental light, the discrimination circuitry being further configured to
generate an indication signal responsive to the reception of reflected reference light.
