Source: Razor scooter A
Cost: little
Pros: “stain”less quality material, height adjustable, retractable (lie on deck), 360 degree horizontally, 360 degree vertically, fish finder bases/mounts are detachable and exchangeable.
Cons: a little sloppy at the lower rotating part (due to Razor’s design?)
Hopefully you have got a good idea!
Patent Pending! LOL!
