Three-paneled Wind Speed Flags show golfers both wind speed and direction to help them determine which club is appropriate for the shot. Flags are weight-calibrated for specific wind speeds. Top panel flutters when wind reaches 6 m.p.h. Top and middle flags flutter when wind reaches 12 m.p.h. All panels rise and flutter when wind speed reaches 18 m.p.h. Each panel is color coded for visibility and labeled with wind speed in either m.p.h. or k.p.h. Solar Max Nylon fabric by Dupont resists UV. rays and mildew, and is double-stitched and bar-tacked at each corner. Single tube lock design allows replacement of pin flag by sliding it over flagstick and tightening acorn nut or placard. Non-furling pivot prevents flag wrap around. Choose red/white/blue or red/yellow/blue combinations. Also in bracket-mounted versions for driving ranges and portable model kits for golf carts.
