I bought two cameras which I use one at 1000 yards and the second at 500 yards. I found the WiFi setup easy and I am able to switch camera views through the TargetVison drop down menu. I use to use a 60x spotting scope and it doesn’t come close to the clarity I see on my tablet at 1000 and 500 yards. All the 6mm bullet holes on the target are identified by the TargetVison program. I had the cameras on for 5 hours of morning shooting (no wind) and had no issues of battery life. However, I wish TargetVision offered to sell the removable batteries for my unit. I’d like one as a backup.
