I work at an air traffic control tower and need to check the gear of each landing retractable gear aircraft. My boss bought two pair of the previous model of this binocular, and it started coming apart at the hand grip and lens connection. They resolved this at the company by adding screws to connect these parts on this model and it's very stable.
