Arca-Swiss Accessory Plate

This arca rail adapter is cut precisely to the same specs as the Sparrow binocular adapter. It makes for easy switching from binos to my spotting scope.

This adapter worked perfectly.

The bases do exactly what they do. Attach optics to pan head. The pan head could be better, not a precision ball mount. And expensive for its range of motion. The third leg is a good idea but versatility of the trek pole tripod isn’t what I’d hoped it would be.
