Customer Reviews (4.8 / 5 · 5 reviews)

Madison ★★★★★

I needed a sturdy base for my marine electronics and this one’s 3.5-inch square footprint fit perfectly on my dash. The hole pattern aligned without any drilling hassle.

Scarlett T. ★★★★★

The mounting holes lined up perfectly with my existing setup, so installation took less than five minutes. The 3.5-inch square base feels solid enough to hold my plotter screen even in choppy water.

Adam N. ★★★★★

I had to drill new mounting holes, but the pattern aligned perfectly once I got it situated. It feels rock-solid holding my electronics in rough chop.
