The livescope or the 3D printed 0-degree mount? The mount has been good so far--survived lots of crank bait pulling runs at 1.5 mph or greater and even a few bumps and accidentally turning my trolling motor the wrong direction when stowing, and only allowing my LVS32 to just rotate positions when that happens. Once I figured out that I still needed the rubber grip or electrical tape to keep the mount from sliding turning on the trolling motor shaft, it's held the same position since.
If I'm not at work or taking kids to their activities, you might find me on "The Rez" fishing. If not there, I could be in the garage working on my boat.
