Goosen complained about Asian crowd last week

SHANGHAI, China -- Ernie Els wants metal detectors to be used to prevent golf fans from disturbing players with their mobile phones.

The No. 3 player in the world called for action after being
disturbed several times during his second round at the Asian
Open in Shanghai on Friday.

"It would be great," said Els. "It will take a lot more
manpower and money at events to organize but ... I'm sure if you
asked the players then the majority would agree."

It hasn't been a good month for Chinese golf fans. Last week at the Johnnie Walker Classic in Beijing, Retief Goosen complained about fans using cameras.

Els, after carding a 10-under-par 62 to go four strokes
clear at halfway, was distracted twice while standing over a
putt on the sixth green when a woman's phone went off.

Unaware of her breach of etiquette, she simply slipped the
phone back into her bag. The South African then missed the putt.

"It seems like everyone has a mobile phone and they get
really excited about the game and seeing their favorite
players," said Els.

"It is a bit of a distraction. You want a bit of quiet over
the ball."

Metal detectors and X-ray machines were used at the U.S.
Masters earlier this month.

In China, more than 330 million people own mobile phones.
Changing their habits may prove difficult.

"If they had the metal detectors at the U.S. Masters this
year, I can't believe that the American fans were happy about
it," said golf fan Jiang Rili, 25. "Nobody likes to be parted
from their mobile."
