How to buy a waterproof digital camera
Establish the purpose of the camera before you start shopping for a non-disposable camera.
Waterproof cameras differ greatly in use and price. Common uses include photographs of hiking, boating, swimming, snorkeling and scuba-diving.
For example, you should know to what depth you need to be able to use it. If you only need it for the pool and outdoor sports, a depth of 10 feet (3.0 m) should be adequate, but if you need it for scuba diving, its depth should be substantially more.
