A:AnswerThere are two remotes by GoPro. This one does work with the HERO9 Black. The other remote is called the Smart Remote and it works with several of the earlier models of GoPro cameras.
A:AnswerYes, the lower button on the left side of The Remote will allow you to mark HiLight tags in your videos. Note that HiLights will only work if one camera is paired to The Remote. If you are controlling multiple GoPro cameras at the same time, that feature will not work.
A:AnswerThe Remote itself does not track GPS data. Some GoPro cameras do have a GPS feature, but that feature is only found in the cameras, and not in accessories like The Remote.
A:AnswerYes, the HERO9 Black can shoot time lapse videos and time lapse photos. The options for these include intervals at 0.5, 1, 2, 5, 10, and 30 seconds; as well as 1, 2, 5, 30 and 60 minutes.
A:AnswerThe Remote doesn't have the equivalent of the touch zoom slider that you can use on the rear screen of some GoPro cameras, but it will allow you to toggle between field of view resolutions before recording to select the FOV that works best for your shot.
A:AnswerNo, water will disperse the signal between The Remote and the camera, preventing The Remote from being able to control the camera if used underwater.
A:AnswerThis remote is not compatible with the HERO7 Black. There is a separate remote called the GoPro Smart Remote that will work with the HERO7 Black.
A:AnswerThe Remote is designed to allow you to control your GoPro camera from a distance. It won't extend the range for live-streaming with the camera. That range is determined by the camera's distance to your smartphone that is feeding the stream, and by the signal strength you have through your phone.
