    How it works

    Seconds to set up. Instant to read.

    FlagSwing sits right where a bad swing would send your club head. Stake it beside your ball, swing, and the flag tells you what your swing just did.

    The basic setup

    Stake it, swing, read the flag.

    1. 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.

    2. 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 will leave the flag undisturbed.

    3. 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.

    Watch the setup on a real fairway.

    Where to stake it, what a clean swing looks like, and what the flag does when the club comes over the top. About a minute and a half. Sound on.

    Setups by fault

    Pick the miss you want to fix.

    Wherever you stake it, FlagSwing marks a spot your club head shouldn’t pass through. Move it, and you change what it checks.

    Slice · Shank · Pull

    Over the top

    The classic fault: the club starts the downswing outside the target line and cuts across the ball. It’s behind the slice, the shank and the pull, the four common misses in our video.

    • Use the basic setup: far side of the ball, flag tip 1 inch out and 1 inch back.
    • Come over the top and the club cuts through the flag’s spot, so it spins.
    • Swing from the inside and the club passes the flag without touching it.

    This is the setup our founder’s PGA pro friend taught with a spare ball, and the one in our video.

    How FlagSwing tells a bad swing from a good oneAnimation seen from above, right-handed golfer. A club swings over the top: it hits the ball and clips the flag, which spins, so it’s a bad shot, shown again in slow motion. The flag is reset. The club swings again on path: it hits the ball and passes under the flag, which stays still, so it’s a good shot.TargetFlagSwingSpins!Stays stillBad shotThe flag spunGood shotThe flag stayed stillSlow-mo replay

    Stricter or more forgiving

    Swing angle

    Your swing angle is the path your club head takes into the ball. The closer the flag sits to that path, the less room your swing has to wander.

    • Start where the video shows: 1 inch out and 1 inch back.
    • Tighter check: once clean swings leave the flag still every time, move it a little closer to the ball.
    • More forgiving: if you’re just starting out or warming up, move it a little farther out.
    • Move it about half an inch at a time, and give each spot a few swings.

    Shot shape

    Draw, fade or dead straight

    Where the flag sits decides which path it catches.

    • Turn a slice into a fade: use the basic setup, behind the ball. The big outside-in swing behind a slice clips the flag. Move it a little farther out to leave room for a fade’s gentler path.
    • Turn a hook into a draw: stake it on the far side about 1 inch ahead of the ball instead. A club that swings hard out across the line after impact, the path behind a push or a hook, clips the flag. Move it a little farther out to leave room for a draw.
    • Groove it straight: use both FlagSwings from your pack, one behind the ball and one ahead, both on the far side. Only an on-line swing leaves both flags still.

    Left-handed golfers

    Same FlagSwing. Mirror the setup.

    FlagSwing works for right- and left-handed golfers alike. Our video and diagrams show a right-handed golfer, so flip them left to right.

    • Stake it on the far side of the ball from you, flag pointing back at the ball.
    • “Behind the ball” still means toward your back foot, which for you is your left foot.
    • Your slice curves left and your hook curves right. The setups for each stay the same.

    Tips

    Get more out of every bucket.

    • Start small

      Begin with half swings and a short iron. Once the flag stays still, build up to full swings and longer clubs.

    • Every club

      Use it off the tee, from the fairway and on those tricky chips just off the green.

    • Safe on a busy range

      FlagSwing takes the place of the spare ball or head cover in the classic drill, so nothing goes flying toward the next bay.

    • Natural grass, or a rubber tee indoors

      Outdoors, it stakes into natural grass. On an indoor range or artificial turf, insert it into a rubber tee instead. Reset it with your club head between swings, and slip it back in your pocket when you’re done.
