Last week I purchased a Competition Electronics Pocket Pro II Shot Timer. I called the company this afternoon with my question but they had already closed. Maybe someone on DC can help me. I have taken the shot timer to my indoor range twice to try it out. Today I set the Par time to 5 seconds. As I understand it, after the starting beep the shot timer will recognize and record the shots for 5 seconds then it will stop. Is this correct or incorrect? Today after the 5 seconds was over and I stopped shooting the shot timer continued to recognize and record shots from other people shooting for a very long time. Is this normal? At the end of the Par time shouldn't the shot timer stop recording shots? My indoor range has 8 lanes side by side. The shot timer sensitivity is set to factory default. I will have to determine if gun fire in the adjacent lanes are causing false shot readings. Thanks!
