Do get extra training:
The sea holds the remains of man tragedies, as the sinking of a vessel is often accompanied by the loss of life. Wrecks still claim lives - the lives of divers inadequately prepared for difficult dives. Exploring wrecks requires a very high level of experience and advanced skill training which is available through all the major diver training organisations.

Do take care:
Wrecks may contain hazardous material, such as oil or munitions. Think of the danger into which you are putting yourself and others if you interfere with them or bring munitions ashore.

Do observe & research:
After safety, the greatest skill you can have is to be observant. Even experienced divers can miss important details about a wreck. Try to absorb every detail when you dive and note them down soon after you surface. You will learn more about a wreck each time you dive on it. Knowing a little of the wreck history will help you appreciate it more

Do respect the site:
Many wrecks of military vessels or aircraft are the last resting place of those who gave their lives while serving their country. It may be an offence to enter or interfere with a war grave. Imagine the distress that such acts cause the relatives and friends of those who died. It is the same as damaging or desecrating a churchyard. Similarly, many other sunken vessels may be the graves of those lost at sea. Please respect them.

Do leave the wreck as you find it:
There are those divers who see a wreck as an underwater supermarket. Resist the temptation to take home souvenirs. Anything removed needs to be conserved. Unconserved, such souvenirs almost always end up rotting away in the finders garage or garden. Taking items often means there is little or nothing left of interest to future generations of divers. In some cases it can also be an offence of theft!
