Review on RAM Mounts Double Ball Mount for Humminbird Helix 5 with Medium Arm - Drill-Down Option (RAM-202-153-202U) by Stephen Pendergrass

This was the perfect piece I needed when assembling the portable sonar mount I use on charter boats. It was easy to install with plenty of spaced holes for creative assembly. It feels solid and doesn't wobble or change position on bumpy boat rides. It can be easily combined with the Humminbird Helix 5 fish finder. This allows me to properly position my fish finder based on where I am sitting in the boat and where my portable fish finder is mounted on the boat. I highly recommend this mount!
