Hannah U. ★★★★★ Oct 20, 2026

The pre-drilled holes lined up perfectly with my A50D’s mounting pattern, which saved me a lot of fiddling. The 1.5" ball is solid and holds its angle well, though the base itself is noticeably heavy.

Violet S. ★★★★☆ Oct 23, 2026

The ball mount feels solid and the base's three holes matched my A70's pattern without any drilling. Took maybe 10 minutes to install, though the screws could be a hair longer for thicker dashboards.

Ryan ★★★★☆ Oct 22, 2026

The pre-drilled holes lined up perfectly with my Raymarine unit's mounting pattern, so installation took only a few minutes. Would have preferred a slightly larger ball for more adjustability, but it holds the screen steady even on choppy water.
