Coda Octopus Group, Inc. said today the Company’s Underwater Inspection System™ (UIS), developed in cooperation with the US Coast Guard, has been purchased by the Sheriff’s Office of Contra Costa County, CA. Contra Costa County will be the first on the West Coast to permanently deploy the UIS, developed after the 9/11 attacks to address the need for a new generation of port security technology to respond to underwater threats.
