One of the requirements for artificial turf surfaces is the ball rebound behaviour under an angle.Deltec developed an Angle Ball Projector to determine this ball bouncing characteristic.The portable pneumatic ball projector launches the ball with exactly 50 km/h at the required 15 degrees angle.The projector is compley self-supporting regarding energy when used in the field,so it can be used under all circumstances.The ball is launched without spin the with a very accurate reproducible speed.The reproducibility exceeds the demands by far.A radar gun (not supplied by Deltec)measures the horizontal speed before and after the ball bounce.The Angle Ball Rebound percentage can be determined with these values.The projector comes with a transport box and energy box.
Your benefits:
Excellent reproducibility
Does not rely on external power
Portable
Ball launch without spin
Precise angle by means of measuring device Exchangeable barrel for different balls
Aplications:Football,Rugby.Tennis
Standards:EN13865,EN15330,FIFA02
