Every year, brave (and sometimes foolish) people try to come up with something new and often incredible to be remembered by.

The deepest swimming pool for diving is 60.02m (196 ft 10 in) deep and can be found at Deep Dive Dubai (UAE), in Dubai, UAE. (Guinness World Records)

Cave Diving Records

Besides extreme deep diving, cave diving is arguably the area in modern diving in which records are most sought after.

Here are a few breathtaking (not literally) diving records achieved in underwater caves today.

People are surprisingly eager to achieve diving records on their wedding days. These are a few of the best ones.

Yes. The entire 18-minute ceremony was held underwater.

They not only used scuba and signals but sign language to communicate underwater.

Not all scuba diving records are super serious.

These are the best funny diving records.

The most people extreme ironing underwater is 173 and was achieved by the Waterman Diving Club (Netherlands) in Oss, Netherlands, on 28 March 2011. (Guinness World Records)

Other diving records

The deepest dive using an atmospheric diving suit was 609m (2,000ft) by Chief Navy Diver Daniel Jackson of the US Navy submerged off the coast of La Jolla California, USA, on 1 August 2006. (Guinness World Records)
Unlike many other Guinness World Records, Mr. Jackson was randomly selected to achieve this record in which the latest NASA diving suit was tested.

The suit protects users from marine life and dangerous environments and lets you walk on the sea floor using external propulsion. Now that’s a cool diving suit.

The deepest “dive” in a hyperbaric chamber was 701 m (2,299 ft 10.37 in) in November 1992, by French diver Theo Mavrostomos. (Guinness World Records)

The first recorded deep ocean dive took place on 15 August 1934, when William Beebe (USA, 1877–1962) and Otis Barton (USA, 1899–1992) descended to a then-record depth of 923 m (3,028 ft) in a tethered bathysphere off Bermuda in the Caribbean. (Amusing Planet)

The Old Gentleman of Raahe‘, at the Museum of Raahe, Raahe, Finland, is the oldest known surviving diving suit in the world. (Interesting Engineering)

It was made of leather and definitely wasn’t a pretty sight. Oh yes, it still works. 😎

So, if you got a few spare minutes, I highly suggest you take a look at it here:

Animals Diving Records

We love to think of ourselves as “diving like fish” when scuba diving.

Here are some interesting diving records by animals that are actually made to dive underwater.

The deepest recorded fish is the Cusk-eel with confirmed diving depths of (Encyclopedia of Fishes)

The longest duration dive by a mammal was 222 minutes (or 3 hours 42 minutes) made by a Cuvier’s beaked whale (Ziphius cavirostris). (Journal of Experimental Biology)
