bought new in November. Clarity was not what it should have been.they found and fixed that problem. And zero was lost. That was a battery pack problem. Recoil causing a loss of voltage to unit with some anker battery packs. I am in southern Illinois. Selling because we are moving and need to free up money for new house.
