US: Florida man aims "laser comb" at helicopter, is arrested

A Florida man aimed a Bosley LaserComb, used to stimulate hair growth, at a Marion County Sheriff’s helicopter on September 2 2015. The pilot was temporarily blinded. In addition, his night vision goggles were overwhelmed by the bright light.

The helicopter crew radioed ground officers, who arrested Mark A. Geohagan, 55, of Ocala. He told officers it was “not a laser” but a laser comb. Geohagan said he was testing the distance the light could reach, and that he meant no harm. Geohagan was charged a few hours later with pointing a laser light at a driver or pilot.

The Bosley LaserComb Elite used by Geohagan has nine red 650nm laser diodes arranged in a line, that normally are directed towards a person’s scalp. When aimed into space, it produces a single, “extremely bright” spot of light as described in more detail after the “Read More…” link below.
