RAM® 雙球鑽石板支架（適用於 Humminbird Piranha 等機型）

The diamond plate lines up perfectly with my fish finder’s screw holes, so installation took under five minutes. Arm holds it steady even when I hit some choppy water. Solid buy for the price.

That diamond plate is seriously sturdy, yet the whole setup stays light enough that my Piranha doesn't feel weighed down at all. The arm holds position perfectly even when I'm bouncing across some choppy water, and setup took maybe five minutes with just the two holes pre-drilled. Exactly what I nee

Installed this on my boat’s console and the B-size arm gives just the right amount of adjustability without wobbling. The diamond plate base fit perfectly on the flat surface with the two included holes.
