A:AnswerYes, it is. If you have any trouble pairing the remote with your Hero5 Black, check the various Youtube videos on the subject or consult with GoPro support. It's very easy. You can control as many as 50 Go Pro cameras with this remote.
A:AnswerYes it will work for YouTubing, it does record in 4K just remember 4K does take up quite a bit of space on SD card so you may wanna pick up a extra one while ya there, the cable you use to charge the go pro is usb on one end and connects to go pro with the other end, I just plug go pro in on the one end and connect the usb end to the TV and/or my lap top, also down load the go pro app to your phone and u can wirelessly transfer anything/everything from your go pro to the app. Hope this helps you, the go pro is quite a bit of money but I’m completely satisfied I have mine mounted to my fishing kayak and it works awesome, def a plus that it’s water proof out of the box and voice activated.
A:AnswerYes, the Smart Remote is waterproof down to 33 feet. Note though that while the Smart Remote and/or the GoPro it's connected to are under water, it's very likely that the connection will not be maintained since water can scatter the signals.
