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.
But they do get paid. A lot. At the top end, caddy pay days can be better than many players in the field. Since June 2006, Tony Navarro, Adam Scottâs caddy, has pulled in $442,548; Allistair Matheson, who walks with Geoff Ogilvy, made $337,888.one estimates caddies can make $1,000 a week at the top clubs. After all, golfers paying $350 to play TPC Sawgrass or $500 to play Shadow Creek can generally spare $50 or $100 for a tip.
