RAM® Twist-Lock™ 複合材質吸盤支架（適用Garmin Astro 320等裝置）

Used the twist lock base on my boat's dash to hold my GPS, and it stayed solid even through some choppy waves. The double socket arm makes adjusting the angle really easy without any fuss.

I mounted my Garmin Astro 320 on the dash of my truck for a hunting trip, and the double socket arm let me adjust the angle perfectly without any slippage. The suction cup held firm even on rough, washboard roads — no wobbling at all.

Took it out on the boat with the Garmin Astro 320 and that 3.3" suction cup didn't budge even over choppy wakes. The twist-lock base is effortless to engage, and the double socket arm lets me angle the screen right at me while navigating.
