  • Good mount and well made
Product Packaging: Standard Packaging
I installed this on a 2002 Tracker. I put this mount in the same place the old humminbird mount was, right by the cup holder. I was installing a new humminbird Helix 10 and this mount works great. It places the graph in the perfect position and the mount seems very sturdy.

  • Solid As A Rock Even With A 12" Garmin Graph
Product Packaging: Standard Packaging
The RAM Mounts Horizontal 6" Swing Arm Mount for Fishfinders & Chartplotters RAM-109HU is exactly what I needed for my boat. The mount is sturdy and well-made, and the swing arm allows me to adjust my fishfinder to the perfect position. It was easy to install, and I appreciate the peace of mind that comes with knowing my expensive electronics are securely mounted. Highly recommend this mount to any boater looking for a reliable and adjustable mount for their fishfinder or chartplotter! ... show more

  • Worth every penny!
Product Packaging: Standard Packaging
This marine Ram Mount is a single 6” swing arm with a predrilled 6.25” x 2” x 3/16” rectangular mounting plate to attach your chart plotter/fish finder. This model 109H has a horizontal mounting base to attach to your boat. I used it to mount my Garmin 73sv and the predrilled holes lined up perfectly. The Ram Mount is heavy duty made from cast aluminum with a black matte baked on finish. The arm has two pivot points that can be rotated 360 degrees each. Each pivot point is controlled with a large knob that is easy to grasp and turn to loosen or tighten without any effort at all. When tightened in the position you desire the arm is securely locked and will not move even on very rough water. The unit does not come with any mounting screws which I do not consider a drawback because they do not know what you are attaching too. The installed unit not only does a good job it looks good too! ... show more

  • It’s great and easy to tighten
Product Packaging: Standard Packaging
This ram mount works very well. It swings and pivots with ease and tightens easily. When using don’t over due the tightening as it will be hard to loosen. I use this to swing into center of deck between two sets of rod holders. When getting out simply swing out of way

  • Perfect Console Mount for a Bass Boat (Lowrance HDS 9 Gen 3 on mine)
Product Packaging: Standard Packaging
Excellent. Absolutely excellent. Holds my HDS 9 Gen 3 very solidly yet allows for easy, smooth adjustments. This thing is surprisingly well built, especially at its price point. The holes even lined up with the factory gimbal so I didn’t need to drill any more. The perfect console mount for a bass boat. Only con for me is the lack of a cable management option. I’d give 4.5 stars if I could for that reason, but didn’t feel it was enough of an issue to dock a full star. I ended up buying a 1 inch thick chunk of HDPE (Starboard) from that big auction site, cutting it to size, routing the edges for a finished look, then cutting a channel into it with a router. From there I had a base for cable management and a base to which the RAM mount is screwed down. For those wondering about what hardware to use to screw down the mount, I found that #12 x 1 inch stainless sheet metal screws (x4) hold it down nicely if -a nut-and-bolt combo isn’t an option in your setup. If you’re not familiar, don’t be put off by the “sheet metal” distinction. they have very coarse threads that bite well and don’t let loose easily. Clearly this is needed for sheet metal applications, but it works very well in wood, fiberglass, and even plastic as with my setup. The added advantage for me was that these screws weren’t so long as to go completely through the homemade cable manager I mentioned above. ... show more
