Sonic cup gun

A paint spray gun and range finder for positioning the gun with respect to a target surface to be sprayed. The range finder provides a user of the gun with information about the distance between the gun and the target surface, with different indications when the gun is too close, too far or distanced properly from the target surface to be sprayed. An acoustic range finder provides visual indications of the proximity of the gun to the target surface. Visual indications include a digital display of the distance from the target surface and may be frozen while the gun is spraying.
