Arken Optics Zulus ZHD520R: Menus, zeroing and updating firmware

Thanks very much to Arken Optics, for the opportunity to review their excellent new range-topping ZHD520R. So that’s Zulu-HD-5-20x with LRF, AND ballistic calculator (BCL). They not only welcomed me being entirely honest (presenting both pros and cons), but also invited suggestions to improve their new scopes, including the firmware.

My photo album including all pages of the user manual can be found here:
