The folks who want to film their adventures underwater may want to consider making an investment in the Ikelite Waterproof Camera Housings.
Most may assume that the Ikelite Waterproof Camera Housings are some larger-than-life camera that’s built specifically to go underwater. But they are actually large cases that can house a variety of DSLRs; therefore whether you have a Nikon or a Canon, you’re covered.
There are to handles that’ll let you steer the camera underwater and a variety of external rigs that are attached on top so that you can use it to push into the buttons of the camera. It’s a great accessory because it means you get to use your own camera instead of shelling out an extra couple bucks for the underwater ones that are usually on the market.
