If there's one thing inexperienced anglers forget when buying a GPS or chartplotter, it's how they'll hold it. Seasoned anglers know they need a sturdy, convenient mount like the RAM Mounts® Ball Mount with Round Base for Humminbird® Helix™ 9, 10, 12, 9 G2N, 10 G2N & 12 G2N, and Solix 12 & 15 units. Perfect for several Helix and Solix models, this GPS mount features a double-socket arm mount with a round 3.68"-diameter base with universal AMPS hole pattern and a 2"x5" rectangular base—combined. Translation: they're perfect for mounting Humminbird units for unbeatable hold with elegant precision adjustability. Rubber-ball socket technology dampens shock and vibration unlike ordinary mounts that just screw in or clamp and stand too stiff. The ball socket in the RAM Mounts Ball Mount with Round Base allows for near-infinite adjustments for a perfect viewing angle.
