Already went back to atn - ATN OPMOD ThOR 5 3-24x Smart HD Thermal Rifle Scope 640x480 Resolution

I updated the firmware and the reticle disappeared. Called ATN tech support and they said this can happen when the scope is older and the firmware jump is large, they noted based on the serial number this was an early production unit. It has gone back and I await its return. If all is well when it returns, I would says its worth it, as it was significantly less expensive with the only difference seeming to be that it is gray.
