| The underbrush of a golf course is predominantly
made up of browns, greens, and blacks (mostly reflecting
from dirt, grass, bushes, twigs, etc). |
| Invneted by an engineer and a nuclear physicist, Visiball Golf Ball Finders use special
blue filters that eliminate all visible wavelengths except
those at the blue end of the spectrum. These special filters
virtually eliminate light reflecting off grass and the
dark objects of the underbrush, thus high lighting white
golf balls. Most dark objects show up only as outlines
while the white golf ball appears to glow with a slight
blue tint. |
