The Universal Double Gripper Digiscoping Adapter for Smartphones from Novagrade features a double phone-grip system for stability in harsh conditions. It accepts any phone up to 4.4" wide, in or out of a case, and its compression ring fits any optic's round eyepiece from 39 to 60.8mm. Readjusting for a different-sized phone takes as little as five seconds. The anodized aluminum construction and soft-touch grippers can be adjusted in any direction to ensure they do not interfere with access to buttons.
