Overview
The Vector Ball S is a 3-inch diameter reaction ball weighing 5.7 ounces, sold as a single unit in a green, red and blue color mix for reflex and hand-eye coordination drills.
Reaction balls are shaped so a bounce off the ground goes in an unpredictable direction, which is what forces the faster visual tracking and footwork this style of drill is built around. At 3 inches and under 6 ounces, this one is sized for solo or one-on-one drills rather than group training.
- Diameter: 3 inches
- Weight: 5.7 ounces
- Colors: green, red and blue
- Pieces: 1
Who it's for
Athletes, coaches or physical therapy clients working on reflexes, hand-eye coordination or footwork drills. Coaches running group sessions will need to buy multiples since this listing is for one ball.
