The Color-Sensitive Cones. In 1965 came experimental confirmation of a long expected result - there are three types of color-sensitive cones in the retina of the human eye, corresponding roughly to red, green, and blue sensitive detectors.
Most PGA Tour caddies make between $1000 and $1500 per week, but they also make a percentage of what the player wins in the tournaments. This usually equates to 5 percent of any finish outside the top 10. Players breaking into the top 10, but not winning, will share 7 percent of their prize with their caddies.
How much do PGA caddies make for the bigtime pros? Answer Wiki. Caddies are paid a base salary + performance bonus (usually 5% of the tournament purse, 7% of a top 10 and 10% for a victory). I've heard the base salary ranges from $1000 to $1500 per week. Taken that into account, you could probably guess the range of what each caddy makes. Forbes (http://www.forbes.com/2007/06/08...) provides a good breakdown of the top 10 caddies back in 2006. It probably doesn't vary too much from here.
