حامل كرة مزدوج من RAM® مركب لـ Humminbird Piranha والمزيد

The 2.5" round base with the universal pattern fit perfectly on my boat's existing holes, no drilling needed. The double socket arm holds my fish finder rock solid even when I hit some choppy water, and the Humminbird adapter clicked on without any fuss.

I was a bit worried the composite base might feel cheap, but it's actually very sturdy and the AMPs hole pattern lined up perfectly with my existing mount. The Humminbird base clicks on securely with no wobble, even on choppy water.

The double socket arm locks tight with no sag, even after a full day of bouncing across choppy water with my fish finder attached. The AMPs hole pattern on the base matched up perfectly, so install took under five minutes.
