Scuba diving requires a minimum level of health and fitness. Chronic health conditions, certain medications and/or recent surgery may require you to get written approval from a physician before diving.
It's normal to be anxious about how it will all work out. Your instructor will assist you with everything!
Skills (generally applicable) - The introductory tech dive will practice their buoyancy and trim with the new equipment configuration. This will help you to dive efficiently. Once this foundation has been established, students can practice locomotion to improve their skills.

Since the beginning of the century, one of the most significant changes in the equipment cave divers use has been the shift from backmounted doubles to sidemount. Not only do a substantial number of cave divers now sidemount, it’s possible that there are more open-circuit sidemount cave divers than backmount cave divers.
Whatever configuration a diver chooses there is benefits for each and in different situations each configuration has its up or downside.
Sidemount diving can be fun, especially if your are a tec diver. Learn how to adjust your rig and how to get in the water with it.
There are three parts to certification. Knowledge development, skill practice and open-water diving. You can do all three on your own, or take a break to complete one of them.

Technical divers can explore wrecks and reefs down to depths of 40 meters/130 feet. They can dive in underwater caves or other areas that are not accessible to recreational divers.
Sidemount rigs also include tank bands, clips, bungees, and likely some more to store your regs. The clips are attached to your harness. Also, their position will affect the position of your tanks.
Sidemount divers usually use two tanks. However, it is possible to use one tank as a standard. I was also told that you can use one tank for deco diving.
Cave passages that have been formed through millions of years of erosion are only available to those who are certified in overhead diving. They stretch thousands upon thousands of feet. The incredible time span in which these caves were created is a testament to their unique beauty and tranquility.
To dive beyond 130ft, decompression divers should add some Helium to their cylinders. This will allow them to enter the realm of the seldom seen. Sometimes, the reefs and wrecks they visit are visited less often per year than astronauts to orbit the moon.
5-6 days
Rebreather training classes are typically 5-6 days long, but can be longer depending on a variety of factors such as the training agency, your local conditions, your instructor, and your ability to meet the class standards.
- Increased Bottom Time A Closed Circuit diver is not concerned with running out of gas because they are only limited by decompression. This can also be reduced by selecting an oxygen partial pressure that provides the diver with virtually limitless bottom times in 60 feet or less of water.
The depth range of oxygen rebreathers (simple closed circuit) is limited to approximately 6 m, beyond which the risk of acute oxygen toxicity rises to unacceptable levels very quickly.
