Abstract
Abstract A golf ball retriever having pivotally mounted claw members which are yieldably urged toward closed position and which are held in open position by trigger mechanism operated by engagement with the ball to be retrieved to cause the claw members to snap closed on the ball. The trigger mechanism includes means for adjusting the sensitivity thereof so that the mechanism operates in response to very light contact with the ball to actuate the claw members. Sighting means is provided for positioning the mechanism accurately over the ball by manipulation with an extensible telescoping handle.
