The golf coach, who worked with Tiger for more than 10 years, has been left baffled by Woods' decision to disappear completely since allegations about his private life surfaced.
"The golfing public would like to see Tiger Woods do a press conference," said the 66-year-old who now coaches world No.2 Phil Mickelson.
"To stand there in front of everybody, take his medicine, be humbled, be embarrassed, be humiliated, and answer the questions. But where the hell is he? We could find Osama bin Laden easier then we can find Tiger woods."
There has been much speculation after Woods announced he was to "take an indefinite break from professional golf" to resurrect his marriage, with suggestions he may sideline himself for up to two years.
Others have cast doubt over whether he will return to the professional game at all, but Harmon is confident that he will be back competing at both the Open and US Open this year.
"You look at where the major venues are this year, two of his favourite venues are Pebble Beach and the Old Course at St Andrews. I think he will play in those," he said.
