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.
Caddies don't have an annual salary like most people do. The President of the Professional Caddies Association (PCA) recently told reporters that high end caddies typically earn a base weekly salary of somewhere between $1,000-$1,500.Again, caddies negotiate this deal with the golfer on a case by case basis.Some could make more. Some could make less. The average PGA Tour player plays between 20-30 events per year, so it would make sense to assume that the average salary would range from $20,000-$45,000.nother 50 golfers made between $1-$2 million, resulting in bonuses of at least $50,000. And if you were the caddie who finished 125th on the money list (the last person to guarantee a PGA Tour card for 2014), you would have received at least $30,508 in bonuses.
