"Many Shipwrecks rest too deep for normal divers"
The World’s best wreck dives include huge sunken shipwrecks that have found their way to becoming windows of history preserved on the seabed. An Underwater Wreck can be in a variety of forms and many historical articles have been written in a wreck diving magazine about how famous ship wrecks met with their demise. Although some were the result of an act of aggression, most of the modern day wrecks tend to be sunk intentionally to create breeding habitats for fish and coral formations.
Most world famous wreck dives are generally large sunken ships, either intentionally or not, but wreck divers can also navigate underwater trains, planes and automobiles that have found a new location below sea level. As the structure of a wreck slowly deteriorates underwater, this artificial reef will begin to attract fish and new coral growth, which is why the sinking of ships and other large man-made structures have become popular wreck diving projects in many top wreck diving spots to help stimulate new ecosystems and attract divers for a wreck diving holiday.
Wreck diving techniques and wreck diving equipment differ noticeably from the norm of recreational scuba. The additional hazards that are associated with wreck dives create extra risks - especially for inexperienced divers. Some of the most common dangers to be aware of would include fishing nets – with potential underwater entanglement problems – and sharp, rusting metal structures which can become serious for divers without proper medical preventative measures such as having regular tetanus injections.
Probably the most serious wreck diving hazard stems from ‘over confident’ and ‘under prepared’ wreck divers who choose to penetrate the wreck without the correct specialist gear.
It is totally unnecessary and completely fool hardy for wreck diving addicts to dive inside a wreck without the bare minimum of wreck reel and at least one diving light. It cannot be stressed enough that wreck penetration requires special training and equipment to avoid the potentially fatal outcome from wreck silt out, loss of direction, entrapment and/or low on air situations.
Many Shipwrecks rest too deep for normal recreational scuba diving. This is why the PADI Wreck Diver Specialty Course is closely related to other PADI scuba courses. The Deep Diver course benefits wreck divers who need to go beyond the normal depth limits for certified divers and the Nitrox Diver certification allows the bottom time of scuba wreck dives to be extended outside the normal NDL’s – No Decompression Limits. The PADI Wreck Diver Specialty Course requires four training dives to complete. However you may recall that the Wreck Adventure Dive from the Advanced Course may be credited by the Instructor as the first dive of the corresponding specialty if appropriate.
