Tec 45 – The Tec 45 Diver course introduces Tec 40 divers to full technical deep decompression diving. Through the course you’ll learn about technical dive planning, equipment and procedures. The Tec 45 Diver course allows the interested diver to make multistop decompression dives that use EANx and Oxygen for accelerated decompression.  Tec 45 qualifies divers to make extended no stop dives, and accelerated decompression dives to a maximum of 45m/145ft.
