Climbing aboard a rescue boat, five-year Howard County paramedic Andrew Froom sits in the driver's seat and starts the Yamaha jet-propelled motor. Lowered into the water, the engine's growl softens as the boat glides across a lake, creating ripples across the calm surface.
Sunlight reflection and murky waters make it difficult to see far below the surface, but Froom says the Howard fire department's latest water rescue sonar and underwater camera equipment enhances emergency responses when saving lives of people and animals.
On May 25, special operations Capt. Vince Baker unveiled the new remotely operated vehicle underwater camera, known as the ROV, and the side-scan sonar-detecting rescue boat at the Centennial Lake boat ramp in Ellicott City.
Fire Chief John Butler and County Executive Allan Kittleman were there to see the unveiling.
Using underwater cameras and sonar technology, water rescue crews are shortening time periods in finding, rescuing and recovering drowning victims. Baker said the equipment also assists in police investigations, hazmat detection and bridge and dam damage assessments and inspections.
"[Divers are] crawling through the water and it takes multiple hours to just eliminate this area" where victims were last seen, Baker said. "When we put the ROV into the water, we immediately see targets and images on the screen and eliminate them."
Purchased using department budget funds, the side-scan sonar cost roughly $2,400, Baker said, and an additional $80,000 for the ROV and its sonar. The equipment was put into service in mid-October.
