The Zeiss Sport Optics Digiscoping to Spotter S1 Adapter is a precision-engineered optical interface accessory crafted to seamlessly pair smart devices with high-end glassing systems. This specialized component ring mounts securely directly onto the ocular housing of ZEISS Victory Harpia (85mm/95mm) and Conquest Gavia 85 spotting scopes. Utilizing an innovative internal magnetic alignment layout, it allows the companion ZEISS universal smartphone adapter bracket to instantly snap into perfect focal alignment in under two seconds. The seamless, stepless circular engineering provides smooth 360-degree rotation, enabling wildlife researchers and hunters to fluidly rotate their cameras between portrait and landscape framing choices without causing any optical axis misalignment or tripod shaking. Machined entirely from premium anodized aluminum and stainless steel hardware, this heavy-duty adapter ring can remain semi-permanently clamped on the scope during normal bare-eye observation sessions without degrading the pristine image clarity of your scope.
