VideoRay LLC

Phoenixville, PA, United StatesUpdated Sep 2005

Company Mission Our mission at VideoRay is to provide the best value and top efficiency in a small inspection-class ROV. Our reason for forming the company was to make ROVs more accessible to more people who want to explore and capture underwater worlds on video, whether for education, aquaculture, research, investigations, security, or surveys of dams, pipelines, wrecks, or water tanks. Product Mission for VideoRay ROVs By Scott Bentley, President of VideoRay The idea to introduce the world's smallest ROV came to me while skydiving over the North Pole three years ago. During the trip, my friend Bob Christ and I visited the Shirshov Institute in Moscow, which developed the Mir manned submersible that explored the Titanic. Scientists at the Institute were working on a microROV that would be small enough to enter other parts of Titanic and the WW2 Japanese I-52 submarine. Bob and I were fascinated, and we started investigating whether anyone was selling microsubs commercially. We were fortunate to find Inuktun in Canada, a company with a design for an 8-pound ROV that had been proven over a decade of use and engineering. We purchased the technology and started VideoRay with dream of introducing divers and underwater explorers to an affordable ROV that could go places no other ROV could go. VideoRay is the only proven, personal ROV on the market, with hundreds of units in operation in around the world. We've continually honed the VideoRay, but we have held fast to our original missions of affordability, portability, usability, and safety in a micro ROV.
