Inside Striker makes a portable golf training aid that gives golfers immediate physical feedback on the club’s swing path, helping replace slices and over-the-top moves with a more consistent inside-to-square motion. Made in the USA, the patented 11-ounce design fits in a golf bag and can be used with every club, from the driver to the putter, at home or on the range. Its alignment slot also works with standard alignment rods to reinforce setup, posture, and aim.
