In July 2017, Phil and Grace Hampton of Orlando, FL, made a 50-minute scuba dive to 86 feet (26m) off Cayman Brac. Nothing special in that, you might say, but inspired by a report in Undercurrent (August 2016) they managed to get that dive documented and certified by the Guinness Book of Records, earning them the title of the world's oldest scuba diving couple. They were both 86 at the time.
The article that inspired them to seek the record was entitled Scuba: the Sport of Grandparents, in which we quoted Phil.
"I am 85 years old and logged my 2,906th scuba dive on my birthday in July 2016, diving with the Turks & Caicos Explorer II. My wife, Grace, logged her 1508th dive in Bonaire September 25, 2015. We will celebrate our 59th Anniversary in November."
Phil was first certified as a diver in 1969, but Grace waited until 1987, about which time they began subscribing to Undercurrent, which may itself be a record.
