For dives past 130ft decompression divers blend some Helium into their cylinders and dip into the realm of the rarely seen. The reefs and wrecks they experience are sometimes visited less frequently in a year than astronauts to the moon.
PADI Training app for Android(tm), Apple (r) iOS devices. Three models should be used with the most recent OS (operating-system) to ensure an excellent experience.
Technical divers explore reefs and wrecks at depths below the 40 meter/130-foot recreational limit. With specialized training, they can explore underwater caves and other places well beyond the reach of mainstream recreational diving.
You will also find tank bands, clips and possibly some additional bungees in your Sidemount rig to store your regs. Your harness will have clips that attach to it. Their position is critical for your tanks.
Items such as cylinders and primary lights, which my be difficult to travel with, are available for rental. Be sure to alert us if you will need any of these.
Academics - Technical courses have similar academic requirements to other classes. Students will conduct some self-study and present their findings to their instructor. A technical course requires that you plan your dives in advance. This is a crucial step to ensure a safe and successful dive. The gas management discussion in overhead and deep diving is more complex than what most divers are used too. A computer program can be used to calculate gas volumes and reserves.
I was a bit numb after my initial pool sessions. I was strapped into the twin tanks, trying to conduct valve drills. But, the Tec 40-45 and 50 courses helped me to feel more comfortable and my skills began to improve. By the end of the course, I was enjoying myself. It's about taking your diving skills, buoyancy and awareness up to the next level. This is what Tec diving offers. This is a great feeling. Knowing you're capable in managing life-threatening emergency situations at depth without the need to ascend to the surface (dues decompression requirements), is an amazing feeling. It's very satisfying to execute your dive program with military precision.
Technical diving means that a diver is not allowed to reach the surface from any point during the dive. It could be due to a ceiling in the form of a cave/wreck or virtual ceilings created by decompression obligations. To avoid decompression sickness, you must perform mandatory stops on ascent when the NDL's are exceeded. This usually requires the use special equipment like Sidemounts and Twinsets. Twinsets and Sidemounts require special gas mixes, additional training, and twinsets/sidemounts to ensure that you can perform these stops correctly on ascent in order to maximize Nitrogen offgassing.
Although I have not yet mastered the art of Sidemount diving, I am proud to be a Sidemount diver.
It's becoming increasingly popular and Girls that ScubaHQ noticed it quickly! There were lots of questions and nerves. So we went to Theresia Gullner, one of the few female tech instructors in Asia. She works at Blue Marlin Gili T Lombok. We were then introduced to the twin sets and given an introduction to technical diving. Here's what we learned from her:
One of most significant changes to the equipment cave divers use since the beginning is the shift from using backmounted doubles towards sidemount. While a large number of cave divers are now sidemounting, it is possible that there are many more sidemount cave diver than backmount.
Sidemount cylinder mounting was first used for cave diving. It has since become more popular in technical diving. They take the dual cylinders apart, one for each, and place them on either side. The diver can't breathe from either cylinder if the regulator fails, but this allows for easier access to valves. Sidemount diving gives the diver an increased horizontal profile and a smaller vertical profile.
Technical divers dive at depths less than the recreational limit of 40 meters/130 feet. Technical divers can access underwater caves and other locations that aren't accessible by recreational diving.
- 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.
