The tools law enforcement agencies use to investigate crimes and ensure public safety are critical to their success. Police departments and sheriffs offices around the country are adding underwater search equipment to ensure their dive teams have the proper equipment to safely and effectively do their jobs. The two high tech tools in greatest demand are the side scan sonar and ROV. Sonar is one of most effective tools for underwater search and recovery (S&R) because it can scan large areas quickly and “see” what’s on the bottom regardless of water clarity.
