Bigwave that is an awesome camera, I have the older Wide Angle Lens one ( not HD) use it on my boats, it is niceeee..... The sound is excellent. Has various settings options that are very useful for sound , video and photos.
You will love it !!
The only drawback I had with the HERO Camera is that the waterproof case latch does tend to break due to the type of plastic materiel is made of . It becomes brittle .
** Bought two extra waterproof cases last month to have as spares.**
Other than that I am very happy with it, had it for the last three years and have no complaints about it other than the one mentioned.
That will be a nice investment for the hobby. You will enjoy it very much.
Hope to watch your videos soon !!!
