>>2402748Depends on your needs i have nikon binos but in my pack i have this gem Steiner miniscope monocular. 2" by 2" 2.8oz light to cary had it for over 8 years in the military an in the woods mostly to scout and see whats ahead or if theres something interesting down below.
Heard ziess has a similar one. But a chest carry rig for your binos frees up your hands.
