Dangers of Diving

Diving has exposed the public to the many underwater wonders of the world. The beauty of the various kinds of life that’s in the deep blue hides the biggest danger of diving. It isn’t sharks or boats or anything else that may exist on or in the water. The real danger to divers is Caisson disease, or decompression sickness.

Also known as the bends, the disease can afflict anyone who goes from a high pressure to low pressure environment. The illness results from Henry’s law, which states in short that when the pressure goes down, gas will form bubbles in a fluid. In the case of the bends, the fluid is the blood and the gas is typically nitrogen.

In an airplane cabin, the same process takes place but at a much slower rate. Therefore the lungs are able to remove the gas before the bubbles have any chance of forming. In the case of a diver coming up too fast, the process is quickened resulting in skin rashes and itching, joint pains, paralysis and possibly death.

Bends Prevention

Preventing the bends requires the diver to ascend slowly, allowing the gas to naturally de-gas. The number of variables to take into account when calculating the time needed for slow surfacing makes it very hard to determine. That is why a diving personal was invented. With its specialized timers and sensors, it can determine how deep the diver is and how long the diver was at that depth. Diving computers conduct its calculations in real time and determine how much time the diver needs to spend at a particular level to surface safely and prevent the bends.

A dive personal in just about every brand and model is able to sense the exact duration of divers being at certain depths. The diving personal can then estimate the blood gas level of the diver and figure out: the time period in which the diver can surface without having to worry about the bends; the duration of the divers stop at each depth in order to surface safely and the maximum depth the diver can reach amongst other things.

The Dive Watch display

The display interface for various forms of divers personal have varying designs, however for the display to be practical it must be clearly read and visible while diving. It should not be cluttered, so the diver does not experience information overload. Further to this, superior models of diving computers will be able to give useful information like water temperature, the required decompression time at each depth and dive resurface rate. The top ranging models are able to transmit the entire dive data to a personal for later analysis.

Certain defining features can really set a dive personal ahead of the pack. By the time a diver has surfaced, high end dive watches will display the time before a diver can board an airplane. One of the quickest ways to get the bends is to board an airplane too soon. High end models are also able to keep track of the air supply in the scuba tanks.

Identifying how much information is provided on the display and if the display is clear and readable is essential when shopping for a dive personal. The consumer should also note the other features that the product contains and what it monitors in diving quantity terms. The Suunto D9 would be the perfect example of a diving personal with all the necessary qualities needed to ensure a safe and secure dive.
