The Tec 40 sub course of the PADI Tec Rec Deep Diver course is a limited, entry-level technical diving program that bridges the gap between recreational diving and full technical deep decompression diving. Certified Tec 40 divers are qualified to make limited decompression dives using equipment that is marginally more extensive than that used in mainstream recreational diving. This course can be conducted on back-mount or side-mount.
This course is not for beginner divers and you will go beyond the recreational dive limits. Prerequisites are previous experience dealing with gas narcosis at depth and the knowledge and skills using Enriched air for breathing oxygen at higher percentages. These include being at least 18 years of age, an Advanced Open Water diver, an Enriched Air diver with 10 dives or more on Enriched Air as well as a Deep Diver with at least 10 logged dives deeper than 30m.
The Tec 45 sub-course of the DSAT Tec Diver course introduces Tec 40 divers to the first stages of full, technical deep decompression diving. Certified Tec 45 divers are qualified to make multi-stop decompression dives that employ EANx and oxygen for accelerated decompression.
The expectation is that a Tec 45 diver intends to continue on in technical diving.
Accordingly, the course not only develops the knowledge and skills to make open circuit technical dives as deep as 45 meters/145 feet, but also begins developing the knowledge and skills the diver will need at the Tec 50 level and beyond.
The Tec 50 sub-course of the DSAT Tec Diver course introduces Tec 45 divers to the first stages of full technical deep decompression diving. The Tec 45 diver comes to the course with a strong knowledge and skill base. The Tec 50 course extends these, expanding existing skills and with an added emphasis on mission planning and execution.
Certified Tec 50 divers are qualified to make multi-stop decompression dives using air, EANx and oxygen with up to two gases for accelerated decompression.
The Tec Trimix 65 course introduces you to using non-hypoxic trimix down to a maximum depth of 65m. There are big advantages using three gases, but you need to know how to do it right and your Tec Trimix 65 certification makes deep exploration a reality.
Ready for the outer edge of technical diving? The Tec Trimix course takes experienced Tec divers and turns them into extreme divers who go deeper and visit pristine sites where few others will ever go.
During the course, you'll make dives as deep as 90m, but once you earn this tough certification, there are no limits.
Your training teaches you to build experience gradually and you do it, because you've made it this far and have more exploring to do.
You get introduced to tec sidemount equipment and dive techniques, including up to six cylinders. While it won't change your dive limits, you will transfer yours skills to tec sidemount diving and be able to dive in this equipment configuration within your existing certification and experience limits.
The PADI Sidemount Diver Course teaches you how to configure and use one or two cylinders mounted at your sides instead your back. Maximize your streamline in the water, reduce lower back strain and take advantage of the increased gas supply for longer dives.
Sidemount diving is configuring the diver’s cylinders under the diver’s arms, instead on the back. This configuration was designed for cave diving and single cylinders because they are easier to haul in situations when divers must carry dive gear through rough terrain to the water’s edge.
Sidemount diving can be used in a variety of different environments and offers also excellent advantages for divers with limited mobility.
