Scuba divers are trained to use hand signals to communicate with their buddies… Special underwater communication systems have been developed to allow divers to talk to each other underwater. A transducer is attached to the diver's face mask, which converts his or her voice into an ultrasound signal.
Diving does entail some risk. Not to frighten you, but these risks include decompression sickness (DCS, the “bends”), arterial air embolism, and of course drowning. There are also effects of diving, such as nitrogen narcosis, that can contribute to the cause of these problems.
With recreational diving, the answer to the question “how deep can you SCUBA dive?” is 130 feet. Proper certification is highly recommended for those depths of SCUBA diving. As a basic open water SCUBA diver, the limit for how deep can you dive is 60 feet.
The key to safe equalizing is to get air to flow from the throat to the ears through the opening of the normally closed eustachian tubes. Most divers are taught to equalize by pinching their nose and blowing gently. This gentle pressure opens the eustachian tube and flows air gently to the middle ear.
For repetitive dives, or multiple days of diving a minimum preflight surface interval of at least 18 hours is recommended. DAN (Divers Alert Network) recommends 24 hours for repetitive dives, The US Air Force recommends 24 hours after any dive, while the US Navy tables recommend only 2 hours before flying to altitude.”

Is it hard to learn to scuba dive? As active recreational pastimes go, scuba diving is one of the easiest to learn. While you're gliding around enjoying the underwater sights, you're engaged in only three basic skills: floating, kicking and breathing.... The necessary skills are not tough for most people to master.
The answer is: yes, you can To get certified as a diver, you need to know basic swimming (ability to float or tread water for 10 min, swim 200m unaided/300m with mask-fins-snorkel). However, to do introductory scuba diving program such as Try Scuba or a PADI Discover Scuba Diving program, swimming is not required.
Most divers know air travel immediately following a scuba dive can lead to decompression sickness.... As you learned in your PADI® Open Water Diver course, it's important to wait 12-18 hours after diving before traveling on an airplane.
Ear pain through scuba diving is common and is caused by the difference in pressure in the middle ear compared to the external pressure as you descend in the dive. Equalising at your decompression stops will usually prevent this pain, but in some circumstances, equalising may not be possible.
The diving board's core is made of laminated wood , which is several thin layers of wood, grouped together. Laminated wood is actually stronger than a solid piece of wood. After rounding the top edge, they lay two wood laminate cores over the resin-saturated fiberglass mattes.
The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.

The definition of a deep dive according to PADI is any dive exceeding 18 meters (60 feet). While that may seem fairly deep, our bodies are capable of diving to far greater depths. Expert freedivers can exceed 400 feet on a single breath, while specialized equipment allows scuba divers to exceed 1000 feet.
Diving pools have to be at least five meters (16.4 feet) deep for it to be safe to do dives from the platform, which is 10 meters (32.8 feet) high.
If you go up too quickly, though, it forms bubbles in your body tissues—perhaps in your joints or in your brain. As long as the air supplied to the diving bell is at the same pressure as at the surface, there's no danger of the bends.

Equalizing when diving: when, why and how Because of this, the water's building pressure while diving causes the gas volume in your body's air spaces to decrease.

The case of California v Greenwood 1988, has been used to claim that as long as a dumpster diver's not trespassing and local regulations don't specifically prohibit it, scavenging food falls within the law.
The force of the water pushes the air up , compressing it as water enters the bottom of the open bell. While there is some water in the bottom of the bell, the bulk of it remains packed with breathable air. But there was one key limitation to this -- the bell could only go so deep and still have a usable pocket of air.

The wet bell is a structure with an airtight chamber which is open to the water at the bottom, that is lowered underwater to operate as a base or a means of transport for a small number of divers. Air is trapped inside the bell by pressure of the water at the interface.
