When drowning calls happen, one department in North Texas is working to cut rescue times by more than half.
The Wylie Fire Department is one of the first in the state to use new rapid-diver technology.
They tested it Tuesday by simulating a drowning at Lake Lavon.
The latest news from around North Texas.
The diving equipment is about half the size of the typical gear.
It lets rescuers jump right out of the truck and run straight into the water.
"Most of getting ready used to have to take place here on the shore in front of victims' families and things," said Wylie Fire Capt. Casey Nash.
In Tuesday's exercise, crews were able to reach the drowning victim in about a minute-and-a-half, compared to about 10 minutes using the old gear.
