A few others can protect it down to around 57 m (187 ft). According to Montreal-based product designer Pierre-Yves Pépin, however, his Ovision housing is good to at least 91 m (300 ft).

 

The main body of the Ovision is carved from a solid block of marine-grade 6061-T6 aluminum, with the main viewing window and lens port made from optically-clear acrylic. The four spring-mounted touchscreen control buttons and the two access latches are stainless steel.

Users start by removing the device's aluminum end cap, sliding in their iPhone (model 4 or higher), then replacing the cap and securing it with the latches. Two O-rings around the base of the cap keep the water out, while a rubber bumper and cushion inside the housing keep the phone from rattling around.

 

Utilizing the mechanical buttons and a dedicated app, users can then switch between photo and video mode, start and stop recording, and review footage or stills. Additionally, they can put the phone into sleep mode by holding down any of the buttons for at least three seconds.
