I ordered these a few days ago and they will be delivered later today. Honestly I am not sure. They listed the small and large tripods, carrying cases and manual but did not mention a calibration rod.
I kept reading about them and thought it would be handy to have if I am going to do some 2,000 yd shooting. I am building a .375 Chey Tac and want to be able to take some long shots. When i found two available i figured I would make the other available to one of the guys at LRH as they seemed to have gotten harder to find over time.
I was not aware of a calibration rod and the ability to possibly correct the calibration, but assumed it might be off in it's calibration I intended to build a trajectory chart using the rangefinder. It means a standard ballistic program would not be useable but I would have field verified ranges in any case.
Have you used yours much and if so how has it worked for you? I appreciate any insight you can provide Bob.
