With any sport or hobby, there are certain unwritten rules of etiquette we should all consider.
This article touches upon efficient ways to operate the ‘cursed’ clip and offers a few ideas on handling known as ‘Clip Management’.
We are often asked about the differences between diving wet and diving dry. Other than the obvious answer – “you don’t need to dry anything but your hair after the dive” – there are some key differences.

Dive enough and you’re bound to have a few “incidents.” Technical dive enough and you’re almost certain to have at least a couple of “hits the fan” moments. TEACH technical diving at ALL, and it’s a whole other level of “pucker factor.” Knowing that we are going to have some sort of equipment malfunctions, environmental/navigation emergencies, and will just simply make mistakes at some point in our technical diving careers, how do we avoid becoming a diving fatality statistic? Follow the rules, keep things simple and conservative, stick to your training, practice, and stay calm.
While 10,000 hours is obviously not a realistic value, it certainly puts things into perspective, doesn’t it? How many of your buddies consider themselves “expert divers?” How many hours do they have under water? The point here is not to shoot anyone down or deflate anyone’s ego, but instead to point out that everyone needs more practice. It is often said that in a true emergency situation, the BEST you can possibly expect to respond is the WORST that you perform in practice. Think about your last skills dive, the worst you performed any of those skills is how you will react in an emergency. Would you survive? Just because you went through a great Deco Procedures course, doesn’t mean you’re now an expert at decompression diving. You have a long way to go, and have only just begun to develop those skills.
We’re all in this to have fun, but chances are we’re going to run into a few problems along the way. As a technical diver you’ve been trained and given the basic tools to resolve those problems. As long as you stay within your comfort zone, keep your skills sharp, follow the rules, and try to keep things as simple as possible, you should be able to keep your name out of the accident reports.
Whether you are just starting your TDI Intro to Tech Course, or have over 200 Advanced Trimix dives, these six essential skills should be practiced on every dive.

Why do divers do stupid things? Well the short answer is because they are stupid. Now I know that the majority of the readers of this article are going to be divers and it’s not usually a good idea to start off by insulting your audience but bear with me. If you look at some of the recent diving incidents that have occurred such as the tragic double fatality of a father and son who died while cave diving on Christmas day, or the diver who refused to analyse his gas an ended up breathing 100% oxygen at 30m or the rebreather diver who jumped in with oxygen, diluent and handsets all turned off then you can see why I might say that. The British Sub Aqua Club publish a summary of diving incidents every year and a brief glance at this will show that dives do a whole range of stupid things. Not only that but they do the same stupid things over and over again. Most of the mistakes made each year are the same as the mistakes made the previous year. The short answer is that divers do not follow their training. It would be very easy to stop the vast majority of diving accidents if we could just force divers to follow their training. If you do what your instructor taught you during your course then you will avoid the vast majority of problems that occur. The thing is that you already know that, I know that, everyone knows that and yet hundreds of divers every day do things that break what they were taught in their training.
Is this because divers are genuinely stupid? or is it because they just act as if they are stupid? I believe that divers do stupid things because they are human and humans make mistakes. However that doesn’t mean that mistakes are inevitable. If we understand why we make mistakes we can potentially avoid them. If we recognise that each and every diver has the potential to make mistakes then maybe we will be a little more careful and a little less complacent.
We all have the potential to do stupid things because we sometimes get complacent, because we rush, because we are not very good at assessing risks, because we are often over optimistic. We do not always call a dive when we should, letting multiple little problems build up until they become a major incident. We trust our own powers of observation and can easily get fooled into trying to solve the wrong problem. Finally we often let other people influence us unduly.
I have tried to bring some of these ideas together and have given a number of talks on this topic at dive shows throughout Europe and the US. The video above was shot at TekDiveUSA (www.tekdiveusa.com) in Florida recently. This conference brought together technical divers from all over the world to discuss exploration, diving medicine and diving safety. As part of the conference I was asked to put together a short film which summarised why divers do stupid things. I hope this film helps explain why there is always a risk that we might do something stupid and hopefully will help you to avoid doing anything stupid in the future.

Despite technical diving being a complex realm, any diver can enter into it. However, one must keep in mind, factors such as the equipment, training, planning, and even price tags are different. These changes are all part of the “deep experience.” To begin, one must look at the equipment. Deep or technical divers often need more gas, bottles with mixed gas, multiple regulators, items like manifolds and doubles bands, mixed gas computers, side-slung or side-mounted cylinders, and redundancies across the board. This need for gear leads each individual diver to search for what works best for them, in regards to the most desirable items and their configuration.
Second, a diver seeking to go deeper and have more technical experiences may(should) seek out advanced training. This training introduces mixed gases, extended range capabilities, equipment configurations, as well as oxygen-based physiology and how it relates to decompression. To accomplish this training, a diver will often research what facilities and instructors he or she can best learn from. (Find a TDI Facility/Instructor here) This again, is all part of the “deep-diving experience.” Dive professionals and dive shop owners must remember that the experience does not just take place underwater. If the dive professionals involved work to provide the best possible experience, the diver will remain happy, the business may recognize more profit, and that same diver may become a loyal customer.
Third, the planning changes for the deep/technical diver when compared to recreational diving. During training, technical divers learn that emergencies may involve hard or soft ceilings. For this reason, the diver must learn how to “bail out,” or safely return to the surface using gasses carried to depth. This need requires the diver and his partner or team to develop a bailout plan for specified depths throughout the dive. If an instructor teaches the diver to be competent and comfortable in this task, the diver is more likely to enjoy it, and look forward to planning deeper dives. Again, quality and competent training will build a better diver who seeks to actively use the knowledge he or she has gained
Fourth, the price tag associated with technical diving can grow in comparison to the prices seen in recreational diving. The experience provided by instructors, boat operators, shop owners, and even other divers will make the expenditures less painful. However, if the diver develops a passion for technical diving, then the cost is justified.
Finally, technical diving skills open up a whole new world for divers. The diver can go places and see things that other divers may not have the knowledge or capability to safely see. Hidden wrecks, deeper marine life, and unique underwater formations become available for technical divers. In certain cases and with proper training, technical divers may even be able to explore places that others have never ventured. “Deep” is a factor related to technical diving, but only part of the overall experience.
Technical divers maintain a certain pride factor within their personalities. They have taken a step that few others choose to take, and for this reason, they enjoy the adventure of deeper technical dives. They also enjoy using complex planning and specified gas mixes to get to these deeper depths. Rather than just enjoying the marine life, diving becomes a complex adventure that demands close attention to detail, extensive planning, and thorough training. If the journey is positive from start to finish, the diver will get the complete experience. This “experience” is what keeps divers wet and encourages them to move forward within the world of scuba.

For the technical diver, decompression is an event that cannot be avoided. To go deep, and stay longer on an open circuit rig, you are going to go beyond your no decompression limits. With this requirement being recognized, decompression periods can be tedious and long, depending on the type of diving performed by the diver. The reality is that an individual cannot reduce decompression stop times without altering a dive plan. To make decompression periods more enjoyable however, a diver can find various activities to pass the time in an efficient and useful manner.
Some ideas for expediting a decompression stop may include:
Divers always seem to be looking for fun and excitement at every turn. This desire is magnified in technical divers. Decompression stops are a necessary break required any time a diver passes his or her no decompression limit, especially if this passage is performed on purpose in a technical plan. If a diver must take a deco stop, the time can be used in an effort to improve personal skills while enjoying his or herself. The reality is that a diver must determine what works best for his or her own personal needs. The goal is to be safe, enjoy the sport, and pass the time in the best manner possible.
