However, there are various types of persons who offer diving services but the most common one is the rescuer diver. The rescuer diver is certified to dive more than 60 m. His main role is to look for objects or people who are missing. He also investigates underwater, collect and record information related to various targets: constructions, installations, ecosystems. The rescuer diver is sometimes responsible for running technical inspection for the ships to ensure that everything is fine.
And the history of the diving services is also interesting. For food reasons or because of the fact that the men were attracted by the high price of pearls and the gold which could be found in the depths of the sea, they have sought since the Antiquity. In the Roman Empire, there were some professionals divers specialized in recovering sunken wrecks load from less than 10 m deep and they were considered the first who offer diving services, in exchange of a price.
But the most interesting part is the one which shows the evolution of the divers' suits. At first this wetsuit was just an improvisation, but nowadays professional divers use some good quality equipment to help them breathe underwater. But this equipment is very heavy. Only a diver helmet weighs over 10 kg.
Nowadays, the recent studies have shown that more and more tourists are interested in scuba diving during their holiday. This is the reason why they choose as holiday destination exotic islands or place where they can explore the depths of the oceans or the seas. But when it comes to scuba diving, it can be said that it is not an activity intended for those who are fainthearted, even more during the night. During the day it can be a new interesting experience, but during the night it can be quite frightening.
In Dubai (United Arab Emirates), for example, there are a lot of tourists that like to go scuba diving in their holiday. Also, this city is well known all over the world for the diving services because there are a lot of people who use shipping as a way of transportation.
