    The problem

    Slices. Shanks. Another wasted bucket.

    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.

    Catches the four common misses

    • ShankHits the heel of the club. Ball shoots hard right.
    • SliceBall starts straight, then curves away right.
    • PullStraight, but left of the target.
    • Over the topClub cuts across the ball from outside. FlagSwing catches it.

    How it works

    Seconds to set up. Instant to read.

    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

    1. Step 1

      Stake it

      Press the pointed end into the turf with the flag facing you, then place your ball just in front of the flag.

    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.

    Benefits

    Built to live in your bag.

    • No more bulky equipment

      Three inches end to end: it fits in your pocket and stakes right into the grass. Use it on the range or mid-round, no setup, no carrying.

    • Instant feedback on a bad swing

      The flag spins the second your swing goes wrong: physical, immediate, right at impact. No video to review later, no monitor to read.

    • Faults and shot shape

      Fix the path behind slices and shanks, clean up whiffs and toe shots, or set it up to turn that hook into a nice draw, that slice into a fade, or just groove that straight shot down the middle.

    • Nothing to set up

      No power, no app, no calibration. Works on natural grass, for right- and left-handed golfers alike.

    Our story

    One bet, one bad habit, one fix.

    FlagSwing started in Sarasota, Florida, with a slice that too often turned into a shank, and a PGA teaching professional who bet our founder $100 he could fix it in three swings.

    Three swings later, he knew exactly what he had to fix. FlagSwing is how he kept practicing it, safely, on a crowded range.
