VIDEO: An Eau Claire firefighter came up with a device that could save the lives of disoriented firefighters battling a blaze. It is a labor of love that has been more than two years in the making. Firefighters risk their lives every day to save others -- running into burning buildings. "We literally cannot see our hand in front of our face," Jeff Dykes, Eau Claire firefighter and creator of Northern Star. Dykes has been a firefighter for 20 years. He said he knows the feeling of disorientation all too well.
