A great fact book about technical diving is ‘Deco for Divers – A Guide to Decompression Theory and Physiology’ written by Mark Powell.
You will need your standard wetsuit, fins and mask as well as a computer, compass and DSMB.
My first courses were technical sidemount, and sidemount. Sidemount diving, which is the name of the course, involves placing your tank into your hands. My hands and knuckles were covered with cuts by the end. It is possible to remove the tanks from the clips and lay them out front of you Superman-style. The afternoon dive went much better after I made some adjustments to our harness. I was now comfortable with my harness, and was 'Superman'-ing with the tanks. Sidemount allows for an extraordinary level of freedom. Matt had set up obstacles courses. Soon we were flying around them, with tanks out front, barrel rolling and even swimming upside-down.
Each PADI Specialty you take will help you get closer to becoming a Master Scuba Diver(tm).
To get started on Sidemount diving you don’t need more than an Open Water Diver. Mind you, it obviously helps to have good buoyancy and trim and you should be able to set up and handle your equipment comfortably by yourself. Sidemount diving will add a whole new dimension when it comes to equipment setup and skills.
Sidemount divers tend to use two tanks. You can, however, use just one tank (I believe it's called the'monkey'), or use more than two tanks when doing deco dives.
Technical Sidemount DivingIt's normal to be anxious about how it will all work out. Your instructor will assist you with everything!
At first I was not interested in technical diving. I vividly remember chuckling at the Tec divers who I saw and wondering what made them want to take more equipment. I love the sense that you can be close to nature while feeling free and connected. Tom was a well-respected teacher. I felt it only right to give him a try as I was working in a dive shop offering Tec courses.
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.
These are the options for you if you're looking for alternative diving lessons and classes, or if you want to find out what next steps should be taken.
When or why I decided to do my Sidemount course I don’t remember. As with most of my diving decisions, it was probably a case of – oh that looks cool, could be useful, I’m going to try it!I knew that Sidemount was going to be a useful certification and something that I could use in the future and build on. I also knew that I eventually wanted to do some proper cave diving and that a Sidemount certification would come in handy for that.
If you plan to go sidemount, particularly if you are a tec diver already, you will need to learn about your new rig. How to adjust it, how it can be used to enter the water, and more.
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.
Although the gear selection is important, entry level tech divers will learn how to streamline their equipment and prevent drag. This maximizes propulsion efficiency and awareness.
- 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.
To register for the PADI Advanced Rebreather Diver course, you must first: You must be a PADI Open Water Diver, but you must also be a PADI Advanced Open Water Diver to become a PADI Advanced Rebreather Diver. Have at least 30 dives under your belt.
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.
