You should look at the Mil pricing of the Mark 5 PR2 Mil reticle. They had an unbelievable price on it Thanksgiving day. I was also looking at the same scopes but with the price of the MK 5 I jumped on it.
Having spent considerable money on cheap ones over the years that always broke I ordered this one. Arrived yesterday and I think I am going to like it. Nice little key chain light too.
I can only speak to the Leica. The newest update has greatly improved the BT connectivity for my unit with the Kestrel 4DOF. I was not having as many issues with BT as others have reported. I really enjoy mine even though I do not use it as often as I would like. For ranging deer out to 600...
I pull the battery and place it in the bottom of the case. That seemed to help my battery life even though I am not getting the hours or ranging numbers that some are.
