The elite grand four and elite grand five limited edition (le) are fully computerized machines that pre-calculated trajectories (speed, angle…) for the balls they shoot. If more than 10% off the balls are not clearing the net or going out, please make sure that:
- The net is 35-36 inches high at the middle
- The calibration has been done correctly. If some balls are still not clearing and even if the test ball is landing on the “T”, re-calibrate the test ball to surpass the T a bit and see how that works. The “T” is a guideline but will vary depending on altitude, environmental conditions, and also the tennis balls being used
- All tennis balls used for playing are in the same condition
Shall this not solve the problem, please contact us so we could assist you.
