3.3. Longest Scuba Dive (Enclosed Environment)
Cem Karabay spent eight days in a pool to surpass his own diving record by two days. From October 21st to October 29th, 2011, he set the record for the longest dive in the world in a controlled environment. For an astonishing 192 hours, 19 minutes, and 19 seconds, he remained submerged in the Activity Plaza at Caddebostan Beach in Istanbul, Turkey. This is a giant pool with water maintained at a constant temperature of 35 degrees Celsius.
It is true that Cem didn’t break this diving record alone. He had a team of 20 people present at all times to exchange his air cylinders, bring his favorite meals, and even provide him with a relaxing massage.
3.4. Longest Scuba Dive in Open Fresh Water
Jerry Hall is an American diver who chooses freshwater to break diving records. More specifically, he chooses South Holston Lake, located near the city of Bristol on the Tennessee-Virginia border, USA.
Jerry Hall has achieved various world records in dive duration. In 2002, he remained submerged for 71 hours, 39 minutes, and 40 seconds. In 2004, he surpassed his own record with 120 hours, 1 minute, and 9 seconds.
It took 7 years for another American diver, Allen Sherrod, to surpass his record in 2011, but Jerry did not give up and focused on reclaiming the record in 2013. His plans became a reality at 13:42 on Friday, August 2, 2013, when he emerged after 144 hours (6 days), 1 hour, and 42 minutes.
Although the media did report on these last two diving records, Guinness does not include them in their records. What could have happened?
3.5. Longest Submergence Underwater with On One Cylinder E Cylinder
While some people can’t make a scuba tank last even half an hour in shallow waters, Jacobus Jacobs managed to stay submerged for 8 hours, 20 minutes, and 38 seconds. On January 27, 2007, the diver carried only one 12-liter tank when he submerged at All About Scuba in Rustenburg, South Africa. We are sure that he just had his head under the surface.
