+In preparation for an upcoming expedition to Lake Tahoe, we are building a stereo camera rig. This rig will be carried by a SCUBA diver and used to take stereo images of shipwrecks, which can later be used to create a realistic 3D model of the wreck. Our target wreck is at a depth of 40-50 ft, so we had to verify that our enclosures would remain water tight at that depth.

+We were generously assisted by Josiah Renfree of the Southwest Fisheries Science Center, who donated his time and pressure tank to test our enclosures for us. The enclosures remained watertight at a depth of 100ft of seawater, so we are confident that they will work for our Lake Tahoe expedition.
