Why FlagSwing
Feel the swing you can’t see.
Most bad shots start with a swing path you can’t feel. The club cuts across the ball, it peels off right, and the swing that caused it is already gone. The usual fixes are bulky frames and pricey launch monitors that nobody wants to haul to the range.
FlagSwing is a three-inch stake with a rotating flag that presses straight into the turf next to your ball: no base, no hardware, no batteries. It slips into a pocket and gives you instant feedback the moment a swing goes wrong.
It takes the place of the spare ball or head cover in the classic path drill, so nothing goes flying toward the next bay on a busy range. Reset it with your club head and swing again.
How to use it
Stake it. Swing. Read the flag.
Step 1
Stake it
Press the pointed end into the turf on the far side of your ball, with the flag pointing back at the ball. The tip of the flag sits about 1 inch beyond the ball and about 1 inch behind it.
Step 2
Take your swing
Swing like you normally would. The flag sits right in the path an incorrect club head would travel. Swing true and your club leaves it undisturbed.
Step 3
Read the flag
Flag holds steady, you swung clean. Flag spins, you caught the fault. Reset it with your club head and swing again.

Which faults does it help with?
It catches the swing path behind the four common misses, the shank, the slice, the pull and coming over the top. Move it, and you can work on a fade, a draw or a straight shot too.
Does it work for left-handed golfers?
Yes. FlagSwing works for right- and left-handed golfers alike. Lefties just mirror the setup.
Can I use it with every club?
Yes, outdoors on natural grass. Use it off the tee, from the fairway and on those tricky chips just off the green. Indoors in a rubber tee, practice with irons, wedges or fairway woods.
What if my FlagSwing breaks?
Every FlagSwing has a 90-day limited warranty against defects in materials and workmanship. If it fails because of a defect within 90 days of delivery, send us a photo and we’ll replace it or refund you, with no need to send it back. It doesn’t cover damage from club strikes or other impacts, misuse, loss or normal wear.
