Technical diving is a discipline involving one or more of the following:
- Staged decompression
- Use of one or more mixed gases such as; Nitrox, Trimix, Heliox.
- Penetration into overhead environments (caves or shipwrecks)
- Use of breather apparatus other than normal open circuit (for example, semi closed or closed circuit rebreathers)
Technical dives may be defined as being either dives to depths deeper than 130 feet / 40 meters or dives in an overhead environment with no direct access to the surface or natural light. Such environments may include fresh and saltwater caves and the interior of shipwrecks. In many cases, technical dives also include planned decompression carried out over a number of stages during a controlled ascent to the surface at the end of the dive.
Why Decompression Diving?
Decompression diving is the next logical step for recreational divers who want to dive deeper and or longer, as well as having a new challenge with their diving.
Decompression Diving Prerequisites
Below are the requirements for any diver conducting any decompression dive from Southern Image or with Image Dive. They are for your own safety and the safety of others. They are not negotiable, so please check that you meet the conditions and have the equipment before the day, as it is upsetting for everyone if we have to refuse to allow you to dive.

What is a Rebreather?
A rebreather is a type of breathing apparatus that provides a breathing gas containing oxygen and recycles exhaled gas. This recycling reduces the volume of breathing gas used, making a rebreather lighter and more compact than an open-circuit breathing set for the same duration.
