The boat was painted in camouflage, making it even harder to find.
Its like looking for a needle in a haystack, he said.
Although wet and cold, the family appeared to be in good health even after spending the night in the wilderness, which was swept by strong thunderstorms Thursday and more rain Friday.
Piedrahita said the missing familys boat had issued a ping signal that located it Thursday afternoon, but that contact was lost.
Rescuers who found the family the next day helped Schreck pull the airboat out of the brush, and he followed them back to the Tamiami Trail.
The boys stepped off the boat first, bundled in heavy beige firefighters jackets.
Schreck said his wife and kids were troopers during the ordeal.
Schreck is a golf pro who oversees three courses in northeast Ohio.
Mike Cavey, president of Granite Golf Properties, which operates the courses, said Schreck is an experienced outdoorsman and fisherman who hunts ducks in northern Ohio marshes from an airboat.
So its not like a rookie going into the middle of the Everglades and doesnt know what hes doing, Cavey said.
But that didnt impress Everglades airboat captain David Wilson, who called Schreck reckless for venturing out into the Everglades on an airboat for the first time in rough weather with his young family.
They shouldnt have been out there, said Wilson, who has driven airboats for Gator Park for almost 20 years. Theyre from out of town, they dont know the area theyre lucky they didnt spend a week out there.
However, Schreck said the experience didnt sour him on the Everglades.
We caught some fish, had some fun, he said. I want to thank the hospital, the fish and wildlife commission and Miami-Dade Fire Rescue. We might even spend a couple more days here. I would even go back to the Everglades.
But, his wife wont, he said.
Right now she said, No! he said.
