A laser indicator includes a top shell covered on a bottom shell, which is fastened to the visor of a golf player's cap, through doweled and hooked joints to hold a laser module, a control circuit board and a battery power supply. The laser module has a laser firing lens mount pivotably fastened to the top and bottom shell at the front and is controlled to project a laser beam on the golf ball to be hit by the golf player, in helping the golf player take the correct hitting position. |
