GSI Reaction Balls 72mm

You cannot predict where it goes, and that is the whole point. Each GSI reaction ball has six rounded hemispheres, so every bounce kicks off at a random angle. Players have to read it late and move fast, which is exactly how reflexes get sharper.

• Unpredictable by design: throw it against a wall or bounce it off the ground and the six-sided shape sends it zigzagging. No two reps are the same.
• Instant coaching feedback: you see reaction time in real time. Great for goalkeepers, catchers, fielders and racket sports players.
• Built for hard surfaces: solid high-density rubber that works best on courts, asphalt, gym floors and packed dirt, where the bounce is sharpest.
• 3 balls, bright colors: run small group drills or keep spares in the kit bag. 72mm size fits kids and adult hands alike.
• Simple drills, real gains: wall toss and catch, partner drop and react, ground bounce chase. One ball, dozens of drills.

Specs: 72mm diameter, high-density rubber, six-hemisphere design, approx 110g, assorted bright colors, pack of 3.

Coach tip: reaction balls need a hard surface to dart properly. On grass or carpet the bounce stays low, so run these drills on court or pavement.
