How are shot value challenges and crossfires handled on the electronic targets at Lodi ?
You will notify a line officer as stated before but as far as the targets themselves here is how it is handled.
Crossfires if you are the receiving target your score keeper (now observer) will hopefully notice a shot appear when you didn't shoot. The velocity will be higher than the velocity of your shots. The farther over the farther it will be. If you are the shooter who does crossfire your score keeper/observer will not that a shot did not appear and mark it as a miss.
Now as far as challenges, sorry you are out of luck. The score is what it is. Unlike with manual targets there is no, well this is close so I'll give it to him, or hey I'm in the lead and I'm going to make this guy earn it. Also the well the hole is outside but it tore the target so maybe I'll count that mark. The human element is taken out. When the hit location is plotted the plug circle is drawn and if it cuts/touches the line you get that value. The accuracy of the system is taken care of during the calibration. So in the case of our range you can challenge but you will loose, because the system is the final say.
The only exception and this is being written into the NRA rules for 10.17.8(b) for approval by the rules committee involves the challenge of a missing shot this is what Walt wrote up following my conversation with him and Denny last week at Perry.
If the system is capable, the target in question and each adjacent target's electronic field will be examined to determine if a missing shot can be located. If it cannot be located or the system does not have such capabilities and (2) two previous shots by the competitor are in the scoring rings of the target and there have been no cross-fires on (2) targets either side on the position being considered, the competitor will be directed to fire another shot on the target and if it registers the missing shot will be ignored.
NRA rules state about a backer, scoring/sighter screens, etc. but in the conversation with Walt about some of the rules not applying to SMT, etc. He said the rules that don't apply you put in a match bulletin stating they will not be enforced. I'm stating this before people quote the rule about a target backer, etc. that is in the NRA rules.
