I shot in the Silver Mountain test at Lodi. I had a lot of questions ahead of time. The concern of targets being lined up with the sensors was one of them. It was explained that exact elignment wasn't a concern, because the target that we're seeing down range is only an aiming point. Even if it's a half inch off, you adjust to what the monitor tells you during sighters. If your bottom of ten ring according to the monitor, then your going to adjust up accordingly. Your hold offs by scoring rings will be the same way. If you have a left to right wind, and you hold 3 rings left. The monitor tells you it's a center X. Your going to continue shooting by what the monitor tells you. That's what's important. Another feature that I liked was the velocity readings at the target. They might not be exact, but here is what happened to me. I was hitting high X ring, then shot a 12 o'clock 9 just barely out. On paper targets you question yourself was it me, or a condition change that through the shot higher? I looked at the monitor list of velocities. Sure enough, that shot had a higher at target velocity than all the prior shots. I know right away that it wasn't me that caused it.
