Cheap Underwater Camera

By Aikednea Johansen


There are a variety of cameras that can be used in aquatic and underwater environments. Camera types and makes range from specialized digital cameras to cheaper disposable cameras constructed for under the water use. Knowing some of the basics of each type of camera can assist you to make a choice regarding a camera in which to invest, whether you are a professional or a budding amateur.

Some disposable cameras are made for underwater use. If you are going on a short scuba or snorkeling excursion and want some thing to take the images, then a cheap, disposable camera is going to do the trick. Certain things to consider for disposable cameras may include dive depth, heat condensation building up from cool waters and warm air environments, and not having a flash. Remember that disposable cameras cannot be put through X-ray machines. Most disposable underwater cameras can be used at a depth of 50 meters.

You may also get a special, rugged version of your disposable camera made with the diver in mind. In contrast to other shockproof, waterproof cameras, these diving and sport cameras have specialized dive and snorkel modes to help get rid of underwater color distortion; rubberized grips around the camera's exterior; and wide-spread controls on the camera body for ease of operation. Producers of these specialized dive and sport cameras, like the Sealife Mini II, also produce wide-angle lens attachments and video and flash lights.

Another genre of digital camera models are point-and-shoot, non-DSLR models that can be immersed between 10 and 30 feet. There are a variety of manufacturers for submersible point-and-shoots, including Olympus, Canon, Pentax, Fuji and Panasonic. These multi-use cameras are usually shockproof, freeze-proof, crush-proof and submersible up to a certain distance or temperature. Many of the recent versions of these cameras also provide high-definition video capabilities and other features, such as carabiner clips, LED illumination, touch screens and face-detection software program.

Specialized cases are made for conventional digital camera models that cannot be submerged under water. These cases must be sized appropriately for your particular camera model and size. Before every submersion, inspect the O-ring particles for debris, such as hair or sand, that may cause leaks while underwater. Apply a small amount of water-tight grease on the surface of the O-ring before re-inserting it into the case. Be sure to rinse the case in clean, fresh water after each and every submersion, making sure that sand along with other debris are clear from buttons and gaskets.
