what bolts/ locking nuts are folks using to attach the base of locator to the RAM mount? I am having a hard time finding such a small diameter bolt. the holes in the base are not very large
You may have to drill larger holes.
I have a “Johnny Ray mount”, that I used with my old locator. I wound up drilling new mounting holes to fit my new 93sv.
I also have a Ram mount that was used for a handheld GPSMAP 76CSx and wound up drilling larger holes in the base to better secure it to the boat.
