Here are some of the key pieces (see the figure):
- Pivot arms: The pivot arms come in two varieties: straight and angled. You use them to put the camera farther from the mount or to rotate it. When you add an angled extension, it changes the mount by 90 degrees, so each one that you add turns the camera. You can add as many arms as you need, joining them with the thumbscrews that come in the GoPro package.
- Quick-release buckle: You get two of them, one of which is slightly larger and more flexible than the other. The pivot arms attach to many of the mounts as well as the quick-release buckle that locks into some of the mounts. When using the quick-release buckle, you just slide and clip, as shown.
- Double-stick base plates: One of the adhesive mounts that accommodates the quick-release buckle is flat, and the other is slightly curved. The quick-release buckle can be used with either adhesive mount.
These plates are permanent, so be sure to put them where you want them to stay.
Even though the base-plate seal is somewhat permanent, you may have to wait a while for it to set and as much as 24 hours during cold weather. It's possible to remove it with heat for reuse. A blow dryer works great.
