After testing the Surfola SF530 for weeks, I'm blown away by its 4K/60fps footage - crisp enough to count seafoam bubbles during my morning surf sessions. The front touchscreen is a game-changer; no more awkward arm contortions to check if I'm recording.

Dunked it 10ft underwater (with the case, obviously) while snorkeling, and the dive mode actually works - colors stayed vibrant, unlike my last camera's murky green mess. The dual batteries lasted through a full day of hiking and cliff jumps, though I wish charging didn't take 3 hours.

Pro tip: Skip the internal mic (sounds like a tin can) and use the wireless mic for vlogging. The app's clunky, but once connected, transferring 4K clips to my phone took under a minute. Not GoPro-level stabilization, but for $100? This little tank survives my skateboard wipeouts and still delivers Instagram-worthy slow-mo.
