Building on the success of their standard model with a single gripper, the Novagrade Universal Double Gripper Digiscoping Adapter offers improved stability in harsh conditions, such as when it's windy or you're on the deck of a pitching boat. Made of lightweight aluminum with a scratch-resistant anodized finish, the adapter can fit devices up to 4.3" (110mm) wide. It features an adjustable height bar for even more stability and security. A second adjustment enables the eyepiece adapter to be precisely centered on the camera lens regardless of its placement on the phone. Being fully adjustable, it can be set so as to not interfere with your phone's various buttons. This model will fit eyepieces from 39 to 60.75mm in diameter using the included set of polymer compression rings.
