I have 6 gopros. They are a good camera and do have voice control. But there are some things you should know before you dive into that realm. 1st, if you run the camera non stop you get about 2.5 hours of filming time per battery. Not terrible, but also not very long. 2) the lens is a fish eye lens and is designed to capture wide angle. They do not do distance very well. They also do not work great in low light ie sun up and sun down.
On the flip side they can do cool stuff. The voice control is one. Can take pictures, video, time lapse, shutter snaps. The new ones are water proof and you can get a additional case to go deeper into the water. This can be used on a pole to plunge the camera into the water and get shots of the fish being landed or swimming away.
You can do a lot with them but also have their flaws. If you have any specific questions you are welcome to PM me. I use them for hunting and fishing videos.
Now before you ask me about editing, I'm just starting to learn how but gopro editor program is free. Luckily for me, one of my best friends is a marketing director and graphic designer he does all of our stuff. But once you get it figured out you can make some pretty cool stuff
They also have a ton of mount accessories to fit your needs. If you go that route you will find more uses for the gopro than your original use. You can pretty much use it as a regular camera for all events.
