The extended range course is the technical entry level course that allows you to start your technical diving adventures. This is a 4 day course that will allow you to dive to a maximum depth of 45 metres and have up to 25 minutes of decompression. You will also be allowed to accelerate that decompression with the use of a stage cylinder that can have up to 100% O2.
