Assuming the water was deep enough- What is the highest you could perform a perfect dive from...and survive?

The world record is around 115 feet for a head-first dive.  I have no idea how much more you could do if you went in feet first.

A Black Sea Bass!\nNow I've been SCUBA diving since 1971 and have been around the Caribbean, Hawaii, and Southern California and thought I'd pretty much seen everything but on this one trip, to San Clemente Island, I was SCUBA diving with a couple of girls on a chartered dive boat off from San Clemente Island one Summer, and I was watching, (with great humor), the two girls trying to load their spearguns down on the bottom in about 30 feet of water when all of a sudden, (on the far side of the girls), a bass about the size of a Volkswagon Beatle comes lumbering up to see what's going on! The first thing that came to mind was the "Fish Pool" on board the dive boat for the person who nabs the largest fish of the day, (and my speargun was loaded!). The second thought was, if I don't make the perfect "kill" shot on the first try, I'm either going for a LONG ride or, at worst, I'll lose my only speargun! Then, as my heart started idling down, I realized that this fish was on the endangered species list and there was no way I was going to get nailed for shooting one these bad boys!!! So, just for fun, I placed my hands on either side of my girlfriend's head and gently turned it towards the fish and watched as she filled the water with frantic bubbles as she shook her girlfriend and pointed to the fish, at which time that girl started blowing bubbles like a freight train! Hillarious!!!\nAnyway, as we all settled down I drifted up and over the girls and headed gently over towards the fish. I got close enough to shake hands before he slowly turned and started heading towards deeper water! What a rush!\n(And me without even so much as a camera!!!!!)

Try it and let us know.  Is there an ocean deep enough for you to SCUBA dive, ICHI?

No. You'd fall through it. It's just water molecules. It sounds cool though!

i dunno. realistically i think 10 or 15 feet on a hard surface would break you ankles and create microfracturesw in your bones water mabye 70 feet

The ocean can be very intimidating. I admire you for trying. But more then that, I admire you for asking for help. Kitty is correct when she recommended using a mask & snorkel. Add to that a set of fins and swimming in a calm ocean is relitively simple.\nKick with your fins underwater, not splashing on the surface, and you'll be able to travel through the water with little effort. When using fins, keep arm and hand movement to a minimum, they'll just slow you down. Oh yes, wear a wet suit, it will allow you to be even more bouyant.  In warm water a 3mil wet suit will be fine. \nIf you are wearing a wet suit, mask, snorkel, fins, and swimming in salt water, there is no way you are going to sink!!!!!\nI'm a scuba diver, been one for a long time, and we have to put on ten to sixteen pounds of lead weight to get underwater with what I'm recommending you to wear. \nBut after teaching alot of people to dive, I believe that your real dilemma is a "Panic Attack ." Listen, it doesn't matter if the water is 6 feet deep or a 1000 feet deep. If you can't stand in it with your head out of the water, the feeling can be alittle terrifying. So, what I think you really need to do, is to build you confidence level up by taking professional swimming lessons and practicing. Then, and only then when you are comfortable in the water, will you be able to go out there, let go of the net, and have fun swimming with dolphins.  Been there, done that! Nothing like swimming with large animals in the open ocean..........Good Luck!!!!

590 ft out of a gondola in Switzerland and 100 or so in California.  If you enjoyed bungee save up some change and go sky diving.  It's a rush you will never forget.

is this for holding your breath?? \n\nThe technique used by the record deep divers is to bring their heart rate down to 10 beats per min, by meditating and relaxing all their muscles\n\nHow you do it? it takes a looot of practice.. I have done relaxation exercises and have gotten my heart rate to under 30.. but those guys are crazy

survive: 400\nsurvive WELL: 2000+  would be a good start

Whichever you can do for the longest at the highest heart-rate.  Thats the best way to determine how many calories you are burning.  But you can't beat swimming.

Both of the answers above are excellent advice. I am a Scuba instructor and like to add to their advice.\n\nRecreational diving is normally up to 40 meters. Please review your certification standards and follow them. If you are certified to dive that deep I would consider not doing it. You should be comfortable in the enviroment you dive in.\n\nIf you always dive over 40 m and always experience Nitrogen Narcosis, I suggest you dive shallower to lessen the occurace.\n\nDiving deep can be fun but it is also very dangerous. You really have to be on top of things. As you know many things can happen other than Narcosis. Remember that diving is a sport and you should enjoy the dive. I have been diving for 30 years and have done deep decompression dives but my favorate depth is about 10 to 35 m.\n\nPlease dive safe. Follow the rules and standards. You will dive for years to come.\n\nHope this helps.

swimming,not because of the skimpy suits either...the body moving thru the water is sleek to me..and diving is what I consider to be majestic..great to watch and even better to do myself! =)

Occupation Diver\nCause of death the bends from comming up 100 feet in too short of time

300 meters (or 1000 feet) is about as far as a human being can go without the aid of a vessel. Dive depth records are a little over 300 m.\n\nThe Eiffel Tower is 300 meters tall, which is not very far at all considering how deep the ocean goes. The ruins of the Titanic, for example, are at a depth of 3,800 meters (which is about 2.5 miles). The pressure at that depth is over three tons per square inch - enough to crush you in an instant!

Yes...more dryland, stretching exercises, and hollow out slightly before entry. Do line ups and get body control. Diving can torque backs either by entries not lined up, or the board's rebound itself.

The diver would be experiencing 3 atmoshpheres at 99ft.\n\n33 x 3= 99

Despite our ability to adapt to environmental conditions, there must certainly come a point where the surrounding pressure would overwhelm the solid portion of our structure--crush bones, break cellular walls, that sort of thing.  Deep sea divers can't go to the bottom of the deepest trenches.  I don't know whether they are crushed first, or some other gruesome death takes them first, but eventually I imagine whatever is left of them would be crushed.
