Housings are a topic that deserves a detailed post of their own and you’ll see one here on The Adventure Junkies in the future. But, until then let me briefly talk about choosing an underwater housing. Also, you can read Basics of Underwater Photography: Choosing Cameras & Housings which goes into more detail about housings as well as ports, lenses and accessories.
How do you use a GoPro hero?
Before you start digging into the reviews, a few notes on choosing a cam that's right for you. You'll definitely want to consider frame rate, expressed as frames per second (fps). Some action cameras offer up to 240fps recording, while others only go to 30fps. For standard playback, 30fps is perfectly fine. It's when you want to slow footage down in editing to create dramatic scenes that frame rate matters. Footage captured at 240fps can be slowed down and played back smoothly at one-quarter speed. You may also want to go for a cinematic look, in which case you'll want one that has a 24fps capture option, the same speed used by most Hollywood productions.
