RAM Swing Arm Electronics Mount
Horizontal mounting base
Buyer feedback ↓The horizontal RAM swing arm uses a bent arm between a screw-down base and a rectangular display plate. Separate pivots let it move sideways without relocating the base.

THE QUICK TAKE
Is it right for you?
This mount suits a screen that needs to swing toward you, then clear the deck. Its horizontal base is useful on a firm console or supported mounting surface.
Skip it for a small rail or unsupported kayak deck. The arm adds leverage and a wider sweep than a short ball mount. Check the entire travel path and cable slack, not just the parked position.
01 / BUYING NOTES
Before you buy.
Use the horizontal mounting base.
The selected version bolts onto a horizontal surface. Other RAM swing-arm versions use a vertical base or another arm shape; they are not interchangeable packages.
Check the full sweep.
The arm and upper platform pivot separately. Allow clearance through the entire arc so the screen does not hit a seat, rail or control.
The display still needs a matching bracket.
Attach a compatible display bracket to the rectangular upper plate. The mount does not replace the fish finder’s own bracket.
02 / AMAZON REVIEWS
The buyers’ view.
Owners describe a sturdy mount with smooth, easy adjustment for positioning a fish finder. Installation experiences vary: one owner's existing bracket holes lined up, while another needed to adapt a bracket and reported receiving no mounting hardware. An owner also missed built-in cable management, making bracket-hole checks and cable routing useful parts of planning the installation.

RAM specifies independent rotation at the arm and upper platform and a horizontal four-hole base. That makes the swept space and supporting surface central to the installation.
RAM-109HU is the horizontal single swing-arm mount with a bent arm. It does not include the fish finder, transducer or a track adapter.
