The Extended range course provides training and experience required to competently utilize air for dives up to 55 metres / 180 feet that requires staged decompression, utilizing nitrox mixtures or oxygen during decompression. The objective of this course is to train divers in the proper techniques, equipment requirements, and hazards of deep air diving to a maximum of 55 metres / 180 feet utilizing nitrox mixtures or oxygen for staged decompression. Many student choose to combine this level when they look at moving into Trimix diving as in some remote destinations its not always possible to get helium mixes and their for requiring dives to be on bottom mix air for insurance purpose.

We run the extended range course stand alone over 5 full days it may be combine with extended range at the discretion of your instructor.
