GOLF: Cheats drive Tiger wild; WOODS SLAMS DODGY CLUBS.
The American No.1 believes every player should hand over his driver to an official to find out if it is within the rules.
Woods said: "First hole, here's my driver - make sure it's legal. Green light, red light, that kind of thing."
Dropping down to almost 30th in driving distances has forced Woods to speak out.
In 1997, he was second behind John Daly, smashing the ball 294.8 yards. Now, at 292.2, he slots in between the likes of Paul Stankowski and Kenny Perry.
Asked if there are illegal clubs on tour, Woods replied: "You could say that."
The physics term coefficient of restitution (COR) measures how quickly a golf ball speeds off the face of a club at impact.
The thinner it is, the more trampoline effect. Golf's ruling bodies in America and Europe last year set the limit at 0.83 for professional tours.
But USGA official Dick Rugge said: "We have seen no evidence of clubs that exceed our limits."
Callaway Golf spokesman Larry Dorman said: "There may be drivers, due to variances in the manufacturing tolerances, that exceed the COR limits
"We go as close as we can but we always test the club before we take them to tour to make sure there's no question.
"We do not want a scenario where a player is accused and ends up embarrassed."
