Swarovski CA-B Clamp Adapter

The CA-B clamp adapter secures Swarovski binoculars and the BTX eyepiece module to a VPA 2 variable phone adapter for stable digiscoping. It ships with two insert rings that tailor the fit to specific optic models. Birders and nature observers gain a steady platform for phone-based imaging without hand shake.

Insert Ring 3 and 4 compatibility

Insert Ring 3 fits NL 32, EL 42, EL 50 and EL Range 42 binoculars. Insert Ring 4 fits BTX, EL Range 32, EL 32 and SLC 42 binoculars. The two rings cover the listed models; optics outside this range cannot be mounted with the supplied inserts.

VPA 2 variable phone adapter interface

The clamp adapter connects exclusively to the VPA 2 variable phone adapter; no other phone adapter interface is supported. Users without a VPA 2 cannot attach a smartphone to this clamp. The system relies on that single mechanical linkage for all phone-based capture.
