London, November 17 (PL) - The International Tennis Federation (ITF) announced today that automatic hawk-eye technology met the criteria required for use on hard courts.

The ITF, the men's (ATP) and women's (WTA) tennis associations and the Grand Slams all approved the Bolt6 Sentinel to make decisions on a match-by-match basis, eliminating line judges.

Since last August the ATP announced for its tournaments (except Grand Slams) the use of this variant from 2025, but now it is generalized for both sexes, after it was previously endorsed for grass surfaces.

However, the system is not being used this week in ATP Finals or Masters Cups, where line judges are maintained.

Although the ITF Committee determined that the technology passed quality control checks, it recommends that each court conduct its own tests before implementing it in a tournament.

The hawk-eye consists of 10 cameras located in the facility and connected to computers, which calculate the exact location of the bounce, and its margin of error is very low, only up to three millimeters.

The only place where it is not used is on clay, because the bounce of the ball is marked on the clay surface and the judge can observe the exact place where it landed.
