RAM® ユニバーサルマリンエレクトロニックマウント - Bサイズ ロング

The long double socket arm holds my fish finder rock-solid even when I hit choppy water, and swapping between the round and rectangle bases took me under a minute.

The double socket arm holds my fish finder steady even when I hit a wake, and the pre-drilled holes on both bases made installation a breeze.

The 6.25" x 2" rectangle base fits perfectly on my kayak's track, and the long double socket arm gives me rock-solid positioning even in choppy water. I've had zero wobble or sagging since I mounted my fish finder, which is more than I can say for my old setup.
