Flatlined ShotMarker — What’s wrong with this Picture?

September 13th, 2022Flatlined ShotMarker — Hey, What’s Wrong With This Picture? A Canadian F-Class shooter (who shall not be identified) was shocked to see this “flat-lined” target from a ShotMarker system. This is 30 shots that have almost no vertical. What’s the deal? ShotMarker uses acoustic sensors for locating shot locations. It is usually accurate to within a few millimeters. The shooter wrote: “I’ve never seen this happen with a waterline.” This is me and another shooter. We fired 30 rounds, with four sighters at 900m in extremely strong winds that whipped back and forth every second. “So what’s the problem? It turned out that the wires of the system were not properly connected. Jay Christopherson, AccurateShooter IT expert and top F-Class Shooter, posted: “The wires were connected incorrectly… the sensors are crossed.” Cal Waldner explained that this ShotMarker system error can easily be detected by performing a “tap test”. A tap test must be performed every time equipment is rigged. Tap testing will detect any wire that is crossed. “Other people who saw this target photo on Facebook stated that they had seen a similar issue, so this is NOT a common fault. The system interprets the target area as an horizontal rectangle and not as a square. — Laurie Holland. “I have seen the exact same result when the sensors were plugged incorrectly.” This happened to several people in one match. Sensors crossed.” Jen Bondurant Jerry StephensonThe ShotMarker System Technology and PerformanceThe ShotMarker System was created by Adam McDonald, a young Canadian genius who also invented the AutoTrickler. The ShotMarker is an advanced system that plots shot impacts on targets using acoustic sensor placed in four corners of the target frame. The central Sensor Hub at each target transmits data to the Access Point at firing line via LoRa, which is a low-frequency RF protocol. This design is more efficient than Wifi and can transmit to the Access Point at the firing line using LoRa, a low frequency RF protocol. Each shot will typically be reported within a few millimeters. The best performance is achieved on a stable frame under calm conditions. Original Post Link in F Class Competition Shooting Facebook Group
