The Arca-Swiss-compatible VEO 2 BH-50WM Window Mount is designed for both outdoorsmen and photographers to use from the comfort of their car. The ball head is ideal for using a spotting scope to observe your surroundings, as well as photography and videography with your mirrorless/DSLR camera.

Spotting scopes with Arca-Swiss-compatible bases (such as the Endeavor HD) can be used without the need for a quick shoe for maximum stability. Clamp base opens to 1.25". Includes a large surface area with textured rubber face for solid grip. Ergonomic locking knobs for ease of use, even in cold, wet conditions with gloves. Separate pan lock with 360-degree markings, enabling more technical panoramas. Includes long Arca-Swiss-compatible QS-61P plate.
