Today is widely known that the marks do not often reflects the real ball impact.

There are many examples in recent years which show a growing demand from players and fans to implement an electronic line-calling system for clay courts.

These systems have already been introduced on hardcourts and grass courts, but clay courts thus far have resisted this change, as the irregularity and changeability of the ground prevent sufficient precision in the electronic line-calling systems that have so far existed.

However, on many occasions the marks that we see on the surface do not actually reflect where the ball has fallen.

And what is this due to?

In tennis matches the player usually runs more than 2,000 metres in a square of little more than 97 m², meaning that the bounces and footprints frequently overlap, or various balls bounce in the same area, making it easy to confuse one bounce with another.

It is also frequently the case that due to weather conditions, such as strong winds or dry conditions, the mark produced may be smaller than the actual impact of the bounce. This is because part of the ground may be missing and therefore not leave a mark, or the wind itself may deform the imprint. Similarly, it could be that the mark left is bigger than the true impact of the bounce. This could be because of an accumulation of dust due to the wind or the movement of the players, or because of the wind generated by a ball moving at 200 km/h, which will already leave a mark before coming into contact with the ground.

On clay courts, as opposed to hardcourts or grass courts, the lines, made from cement or PVC, are fixed and therefore slightly raised above the ground. When a bounce occurs which touches the line, it means that part of the mark is lost, and it becomes difficult to determine where the bounce starts and finishes.

For these and many other reasons, tennis enthusiasts and players are demanding an electronic line-calling system for clay courts, but traditional systems were not able to deliver the required accuracy.

As we explained previously, up until now there has been no electronic line-calling system with enough precision to be accepted on clay courts. These systems work by scanning the surface of the court mainly before matches, but on a clay court, which is an irregular and constant changeable surface, these systems increase the margin of error. For example, the system cannot scan an accumulation of dust formed during a match constantly, so if the ball bounces on that spot, the system could detect it as flat ground and it would therefore be the wrong place.

For this reason, in order to help avoid uncomfortable moments which lead to arguments, and to make the game fairer, Foxtenn has developed a revolutionary technology capable of capturing the real image of the exact moment of the bounce. With more than 40 synchronised cameras with ten lasers which scan the court, each camera gathers 2,500 images per second (more than 100,000 images each second in total), Foxtenn does not miss any details of what goes on at any given moment on court. It should also be said that because the cameras are located at ground level at the end of each line, there is no room for margin of error, since the exact point where the ball makes contact with the ground can be seen with absolute clarity.

The system, officially approved by the International Tennis Federation (ITF), the ATP, the WTA and Grand Slams, is the solution for clay courts to finally have a video line-calling system which is 100 % accurate.

In this way, clay court tennis would have the security of being able to use an innovative system that genuinely determines if a ball is good or bad, avoiding all doubt and adding to the entertainment, with the intrigue it generates both on court and on television. Only FOXTENN 100%REAL BOUNCE ACCURACY is able to see the exact moment of contact and show a REAL IMAGE PROOF of the truth.
