Neat idea- a waterproof video camera that straps to your head with a headband for shooting underwater videos. The tiny tube-shaped camera records video only (no audio) at a puny 320 x 240 pixel resolution. It can shoot for up to 3 hours on one charge. It connects and charges via USB (what doesn’t these days?).
Now before you start having dreams of becoming Jacques Geeksteau or Steve Nerdwin or something, you should know this is made by legendary crapgadget maker Thanko, which means it’s from Japan and probably of iffy quality. You’re probably better off rigging up a regular waterproof camera to a headband with some duct tape.
