Whether you have a GoPro/ action camera, or a standard camera SeaSucker has a camera mount for you. Maybe you have both a GoPro & a professional camera, but you don't want to buy two camera mounts? Then you probably want the standard camera mount. You can mount by using the socket arm that has a 1/4 20 camera stand and can be tightened & loosened as needed to lock into place. The height can extend to 5.5 inches, and uses SeaSucker 4.5- inch vacuum mount. The other two camera mounts are designed specifically for action cameras. The main difference on these two arms is the mount. The standard arm has three inches of height off of a low-profile 4.5- inch vacuum mount. The flex mount has a seven inch arm with the ability to point wherever you want it to, and is also on a 4.5 inch vacuum mount. One of these SeaSucker camera mounts should help with your photographic needs!
