    • Perfect Console Mount for a Bass Boat (Lowrance HDS 9 Gen 3 on mine)
Product Packaging: Standard Packaging
Review Image by Andrew
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

Extremely stable, good adjustability, and perfect size for large units. These mount quite nicely on flat surfaces, like your console or side of boat. High quality design.

    • 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

Fits my Lowrance Hook 9 perfectly. I mounted it to the bow of my boat. It’s sturdy, easy to adjust, and the construction seems like it will last a long time.

    • Almost perfect
Product Packaging: Standard Packaging
This thing is hefty! It has a good weight to it and it is incredibly well built and sturdy. Unfortunately for me, and maybe this will help others out there, the predrilled holes will not fit a Humminbird Helix 7. I have the G3N and the holes do not meet up. There are also zero hardware included so you'll need to make a trip out to your local hardware store to pick up some stainless steel hardware. You will also need to come up with a creative way to make it work with your mount if are planning to run this on a helix 7. Other than that, it is fantastic and I recommend it to anyone looking for a sturdy mount. ... show more

RAM is the best, hands down. On my latest boat purchase, I tried to be smart and get knock-offs from the big box store. It was a waste of money, I ended up buying RAM anyway. These are absolutely solid, no issues whatsoever. I only wish I had bought a 12" & 6" instead of two 6" ones. Great job, RAM. Thanks for making them in the USA. ... show more
