Universal Mount Base
The Universal Mount Base is an integral part of the Universal Mount. It is an adhesive backed "holder" for the Universal Mount.
It's flexible, allowing application to curved or flat smooth surfaces.
It is sold separately to allow you to apply them to various desirable CAPTIONHD mounting locations like helmets, cars, boats or whatever. The Universal Mount snaps into its base, so you can easily remove the Universal Mount and camera and move it to another location. The base stays where it is for the next time you want to mount the CAPTIONHD there.
