RAM Mounts' ball-and-socket system is the universal standard for mounting fish finders, phones, cameras, and accessories on boats, kayaks, and ATVs. Here's what you need for a clean, adjustable fish finder mount.

RAM Tough-Claw Ball Mount (Rail/Bar Clamp) $$

Clamps to any 7/8" to 1" rail — no drilling required. Adds a 1.5" ball for attaching an articulating arm. Universal for most small to mid-size fish finder heads.

RAM Double Socket Arm (Medium) $

The articulating arm between two ball mounts — positions the head unit at any angle. Medium arm covers 4.5" extension, long arm covers 9.5". Match arm length to your installation.

RAM Round Plate Base (Drill-Through) $

Flush-mount base that drills to the console top — the most permanent, most stable installation. Requires drilling but produces the cleanest look.

Garmin/Humminbird Quick-Release Cradle with RAM Ball $$

Manufacturer-specific quick-release cradle that mates to a standard RAM ball — lets you remove the head unit in seconds for storage while leaving the mount installed.

1-Inch vs 1.5-Inch Ball Systems

RAM uses two primary ball sizes: 1-inch (B-size) for lighter accessories under 3 lbs, and 1.5-inch (C-size) for heavier accessories up to 6+ lbs. Fish finder heads (7–12 inch units) use the 1.5-inch C-size system. Kayak accessories and small phone mounts typically use 1-inch. Make sure all components in your mount system use the same ball size.

Frequently Asked Questions

What RAM mount ball size for a fish finder?

1.5-inch (C-size) RAM ball for fish finder heads. The larger ball provides the load rating and stability for 7–12 inch units. 1-inch (B-size) is for lighter accessories. Don't mix ball sizes — components are not compatible across sizes.

Do I need to drill to install a RAM mount?

Optional — RAM's Tough-Claw and track-mount systems clamp to existing rails and tracks without drilling. If you want a permanently mounted base on a flat console surface, drilling a round plate base produces the cleanest and most stable installation. Both work.

What's the difference between RAM and off-brand mounts?

RAM's glass-filled composite material is UV-stable and impact-resistant over many seasons. Off-brand mounts often use inferior plastics that crack or lose grip after UV exposure. For a fish finder you're trusting with a $500+ investment, the RAM hardware is worth the premium over generic mounts.
