But here it is... Supposedly, it will help you find a golf ball in a 600 square foot area, potentially by being able to recognize the shape a dimple, I am guessing...
Now 600 square foot area is not THAT big of an area, but it would be useful especially if you are looking into the sun...
Of course, this gadget costs $260 which would actually pay for probably 3 years worth of golf balls, but hey, that's not the point!! (I forgot what is, though...)
