Great, but not for diving.
- Familiarity: I've put it through the wringer
Not surprisingly, the floaty backdoor doesn't work when scuba diving. The pressure compacts the backdoor down to a squished up nothingness. But it will still work just fine at the surface. Don't be alarmed if you take it diving and this happens. This saves your GoPro's life when dropped overboard or lost boogie boarding.
