Best underwater camera or case?

I'm looking for a high quality underwater camera/iPhone 4s case to go snorkeling and swimming with. I mainly care about how clear the photos are, I'm hoping to find something that produces crystal clear quality. Also, it needs to be under 100$.

For $100, not going to happen.

companies who make under water cases do so mostly for dslr cameras. I've never heard of one for a silly phone. If you want real under water photos it's going to cost you. Camera perhaps $800,
case probably $1, 200. That's the way it is.

Under 100$? No offense but my man, seriously, this budget can't bring an ideal waterproof camera for you unless you would like to choose a disposable underwater camera.
Normally the prices of a good camera are between $200-500.
Anyways let me recommend an awesome one to you Sony DSC-TX20 16.2. Check it out here http://best4.reviews/best-underwater-camera/

If your iPhone 4s is the quality that you are satisfied with, there's a compatible underwater housing.
