The TDI deco procedures training is an exciting step further into your dive career. After your training, you will know how to plan and execute deep dives, stay longer underwater and perform mandatory deco stops safely.
Can you become Deco Procedures Diver in your recreational configuration?
At this level, you can still train in your properly configured recreational gear with just a single extra tank for the deco gas. Therefore, you will only need an extra regulator and stage rig, and you can still join regular dive operations.
This configuration is a great option for going on a little deeper and longer dives while greatly increasing your safety, skills, and knowledge with minimal extra investment in dive gear, which is a great advantage.
Do you want to dive deeper and become a serious tech diver?
If you are still a recreational diver but already know tech diving is for you, this course should be combined with or follow an Intro to tech training (learn how to dive in a twinset) or a Side Mount course.
At Deep Dark Diving, all instructors have experience in technical diving in both configurations, diving in caves and the ocean, and can objectively answer any questions about the pros and cons.
Try dives in back mount or side mount configuration.
If you still have not decided between back mount or Side Mount, Deep Dark Diving offers try-dives in both configurations.
One day per configuration, we discuss the advantages and disadvantages of the configuration in different dive environments.
We perform basic safety drills and discuss all the required drills during each course.
We go for a fun dive so you can get a real-life experience and a good feel for the experience.
You then know in detail what will be expected from you for an Intro to tech certification versus a side mount certification.
Is TDI Advanced Nitrox Certification Mandatory?
Although not mandatory, you will get the best out of this Deco procedures training if you are an Advanced Nitrox diver. You can use mixes above 40% oxygen for your deco, making it significantly shorter and more efficient. Of course, Deep Dark Diving can combine Decompression Procedures and Advanced Nitrox.
Combining Intro to Tech or Side Mount, Advanced Nitrox, and Deco Procedures training will be the foundation of all your future technical diving.
