Silently Diving with Semiclosed Rebreather Draeger Dolphin

The Problem

Why do we see a lot of fish while diving, but if we want to make a Foto we only get the caudal fin? The Reason is, that as a normal Diver we are too loud . Especially in waters, where are not thousands of divers diving, fishes are not used to hear the noise of bubbles and they escape. The Resolution is to dive with a Rebreather, so that we can dive without Bubbles and silently.

Advantages

In addition to Diving silently the are more advantages of Diving with a Rebreather: + longer Bottomtimes because of higher Oxigen partial pressure + longer Divetimes because of efficient Gas usage + light and comfortable Gear + the breathing gas ist warm and moistrurised + Gas usage independent to the diving depth Do you want to get to know the feeling for diving without Bubbles? We can introduce you in Diving with the Rebreather Dolphin or you can do a complet Course to become an autonomous Rebreather Diver.

Diving with Nitrox

Nitrox is the name for a mix of gas, consisting of nitrogen and oxygen, with more than 21% oxygen. The common blends for this type of diving consist of any mix between 21% to 40% oxygen. The advantage of diving with Nitrox, is that the nitrogen in the air is reduced and therefore you absorb less nitrogen into your body during your dive. Which signifies a clear prolongation of zero time in comparison to normal air and for the same reason safer. This advantage is even more significant for some types of dives, for example diving from boats to see wrecks. For example: If your zero time on an immersion at 24 meters with normal air is 31 minutes, with Nitrox 32% oxygen your zero time significantly increases up to 60 mins! The management of Nitrox needs special care because the higher proportion of oxygen makes it hazardous. But the safety management of Nitrox is easy to learn with a special course of diving with Nitrox.

Spezialcourse: Diving with Nitrox

The course consists of two units of theory and two units of practical. With us you can learn the safe use of Nitrox ( necessary equipment, safety management, the filling of the bottle) and the planification of the immersions with Nitox and for example you can calculate your zero limits to any specific mix of Nitrox.
