Sidemount cylinder mounting was developed for cave diving. They have been more popular in technical diving ever since. They are able to seperate the dual cylinders and mount them on either end of the diver's body. While this prevents the diver from breathing from one cylinder in case of a failure of the regulator, it allows them to have easier access to the valves. Sidemount diving provides a diver with a more horizontal profile but a smaller vertical one.
There are many great readings about technical diving. Some are stories of personal experiences and adventures in technical diving that are definitely worth reading. Some of the greatest books for sure are:
There are two options available with most agencies: technical Sidemount or recreational Sidemount. Similar prerequisites apply to both TDI or SDI. However, the tec-sidemount course will increase your skills. The course will also require you to learn more about them. Perfect trim and maintaining your level during the skill development is a must.
This scuba diving course is also offered by another agency, PADI tec sidemount diving.
After successful completion, the Tech Diver Level 1 can be started and allows a diver to dive to 51m using appropriate Trimix gas mixes beyond 30m. It is also possible to start Cave Diving Training after the Fundamental Tech Pass.
A great fact book about technical diving is ‘Deco for Divers – A Guide to Decompression Theory and Physiology’ written by Mark Powell.
The very general definition of technical diving is to be exposed to a ceiling that does not allow a diver to ascend to the surface at any moment of the dive. This might be due to a real ceiling, in terms of a cave or a wreck, or a virtual ceiling created by a decompression obligation. In this case, by exceeding the NDL’s, mandatory decompression stops have to be performed on ascent in order to avoid any case of decompression sickness. In most cases this requires the use of special equipment, e.g. Twinsets or Sidemount, special gas mixes and of course additional training to be able to perform those stops accurately on ascent to optimize off-gassing of Nitrogen.
Every PADI Specialty completed will get you one step closer towards the Master Scuba Diver(tm).
Television, magazines, stories from a friend – it doesn’t matter the source, exploring the underwater world and escaping the surface is enticing and exciting. So how do we keep exploring? What exactly is technical diving?
Know what you're getting. Prices include instruction, eLearning fees and other costs. You should also consider that eLearning costs can vary from $140 to $280. In other words, a course that costs $640 may cost as much as a $500 course you purchase from us if you are required to pay for the elearning separately.
With most agencies you can choose between recreational Sidemount and technical Sidemount. The prerequisites for example with SDI and TDI are the same but the tec Sidemount course will add more skills. It will also ask more of you in terms of mastering them – perfect trim and keeping still and leveled during your skills is a must!
Even though the gear choice is important, the entry-level tech diver can learn to streamline their equipment to minimize drag and dangling items. This optimizes the profile of the diver's equipment for optimal propulsion and awareness.
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.
