MASON CITY, Iowa (AP) - More than a dozen firefighters and state personnel are using sonar technology for water search training in northern Iowa.
Mason City firefighters and officers with the state Department of Natural Resources trained Monday with technology that uses the reflection of sound waves to search for objects.
DNR officials say the technology helps them do more efficient work while keeping emergency personnel safe.
The Mason City Globe Gazette reports the sonar technology can search a swath of water that's up to 160 feet wide at a rate of about two miles per hour. The waves are then processed into an image that can be viewed on a computer monitor in a boat.
Mason City officials say the technology can be used for recovery missions.
