There are many lessons to be learned but these seven can help provide a solid core. Technical diving may not be on a diver’s goal list, but its lessons have been hard fought and should not be treated lightly.

by Rob Bradish:
Ahhh, the thought of buried treasure!! I would be willing to bet that if I were to interview a thousand divers, at least one or two became involved in diving because of some story they had once heard about finding buried treasure! I remember one such story being Peter Benchley’s, “The Deep,” in which they describe the famed “Three Lock Box.” Such a box was kept for only the most important items and required three separate keys, maintained by three separate individuals, to be opened. This insured that the property owner would receive the property to which he or she was entitled. In comparison, a “three lock box” can also be an effective metaphor for dive preparation.
So often when thinking of dive preparation, the diver may limit his or her self to pre-dive gear packing and the planning discussion that goes on during the ride to the dive site. However, if someone is to be truly prepared, there is much to do long before the day of the dive. In fact, when examining preparation, there seems to be three clear keys to Effective Preparation for Every Dive.
From a personal perspective, the first key has to be mental preparation. Preparation of this type extends far beyond using a computer to pre-plan your time at depth 50 minutes from now, and requires some steps to effectively get there. For example, the diver must recognize his or her own capabilities. Is the dive being considered within the realm of the diver’s training? Is the site a new site or one dove many times in the past? Does one have all of the appropriate skills, tools, and techniques to complete the dive safely? Participants in some activities are encouraged to visualize, a process of mentally walking through the event, attempting to identify possible challenges or areas where an incident may occur. The night before a dive, visualization can help one determine choices for gear while packing. On the ride to the site, visualization allows the diver to prepare more directly, while witnessing environmental issues that will likely affect the dive. Without this kind of mental preparation, a diver cannot just say they are ready to dive on any given day.
Few people look forward to loading and unloading heavy gear. Hauling tanks back and forth from a dive vessel, or climbing back on board a boat using a dive ladder can require a lot of effort, making physical preparation the second key. While much of that preparation should occur months and weeks before a dive, through exercise, skills practice, and healthy habits, it continues right up to the day of the dive. Frequently, a dive actually begins with a drive to the departure location, either the morning of or the night before. Eating a healthy meal, hydrating effectively, and arriving well-rested are all part of physical preparation. The fact is, staying up until 2 am the night before drinking beers with friends might seem like a great start to a weekend, but not to a weekend of diving. Knowing such activities lead to the increasing probability of DCS incidents, it just doesn’t make sense. Knowing there is another diver, who may depend on his or her buddy, makes it even more important to be able to perform at optimum levels.
Obviously, gear preparation is something that cannot be overlooked and it is our third key. Scuba diving is called a gear intensive sport for a reason. The fact is people do not have gills, and if we are to enjoy what the marine environment has to offer, then equipping ourselves to exist in that environment is important. Annual maintenance is vital to safe diving, if only to insure the life support equipment is performing to standard. Trying to verify gear functionality on the way to a dive site however, is not preparation. Many find it effective to “flat diver” the gear before packing. Essentially, one would lay everything out and make sure that everything needed for the day’s dive is ready. In contrast, the only way to verify regulator and buoyancy compensator functionality is to assemble and test each delivery and exhaust point. Batteries and bulbs need to be fresh in lights and computers. Surface marker buoys and lift bags should be clean and ready to deploy. Finally, is the “Save-a-Dive” kit adequate to actually save the dive? Will the spare mask and fin straps work properly with the gear being packed?
While “plan the dive, dive the plan” has been a part of the diver mantra since the early days, it is important to note that such planning begins long before the day of the dive. Effective mental preparation, through training, research, and visualization are all key components. Physical preparation with effective exercise and living habits are also key. Finally, equipment preparation, not only in maintenance of equipment but in its proper selection for its anticipated use, is the final key. Only with all three keys, can we effectively unlock the “three lock box” of dive planning. Only at this point can the diver effectively determine the goals, depth, and duration for the dive. Even the seemingly simple tasks of entry and exit need to be planned.
Finally, never forget the post dive plan! It would be a shame to go through all of that preparation and planning, failing to include a stop at the local tiki hut for a meal, libations, the telling of lies, and sharing of discoveries!!

Deep diving is a portion of recreational scuba diving that can present dangers and concerns for any diver. These factors can be avoided through proper technique and training. First, divers must utilize common sense and safe practices prior to getting wet.
So, let’s start off with a level set. I started diving in 1977. I was not a professional until about two years ago, and while I have traveled a fair amount, I am certainly not a once-a-year, off to the islands kind of diver. I am, for the most part, just like most of you; I like to dive. This is just my opinion and I encourage you to think on it and more importantly, develop your own response. That said, with over 35 years of diving, I have never gone into unplanned decompression, never run out of gas, and never had an incident become an accident.
I am constantly shocked at the number of divers on a boat dive that need to spend 8 – 10 minutes on the line at 20 feet during a recreational dive. Even scarier is the frequency with which I will hear someone come up the ladder with their computer beeping. When asked, they seem shocked and say something like, “I wondered what that was.” Moreover, an informal survey among charter professionals seems to indicate many of these divers are younger, some with just a few years or dives under their belt. This worries me because as I review the training and knowledgebase available to divers today, the detail is much greater than what we previously had.
So, it begs the question, why are divers today, who are better trained and have more information available than ever before, experiencing incidents that we all know, for the most part, are avoidable?
So, what are some differences between new divers and those who may have more experience? Well, right off the top, I have a few rules I dive by, many of you may have heard before.
1. Plan your dive, dive your plan. We have all heard this for years, but how many especially in our age of computers, actually do it? Most computers even have a modelling software built in to help you. But this goes way beyond anticipating your depth and runtime. In sports and high risk activities, people are taught visualization as a means of preparation. The point here is to, first, psych yourself up for a positive outcome, but more importantly, try to visually prepare and foresee any incidents before they occur. Sure, you can talk about what you hope to see and your separation plan, but do you talk about your dive time? What happens if you go to deep, or stay to long? You get the idea, sit with your buddy and talk about the dive, the goals, and the contingencies to insure you both have success and a good time.
2. Three strikes, I’m out. This is one that is personal. I have found that if I have three mini-incidents, my head can get out of the game, and the best thing for me to do is call it. This even includes driving to the charter! I have also learned for me specifically, the number one thing that can lead to an incident is new equipment or a new configuration. Not yet familiar with that new computer? Get a phone call from the boss about work on the way to the site? Can’t quite get your kit to feel right? Any of these items can take your mind out of the game, but a couple or more together, and I know I will be distracted.
3. There is no dive today worth all of my diving tomorrow. Seems simple, but I am always shocked at the number of people who are afraid to call a dive. Fifth dive of the day and you suddenly get a booming headache? Long ride out and you notice the boat bobbing more than you are used to? No matter how hard you try, you just can’t wrap your head around the dive? CALL IT! There is no dive that is more important than all my future diving. This also leads to an additional rule that tech divers frequently state. Any diver can call the dive at any time, for any reason, without fear of repercussion. Now don’t get me wrong, there will likely be some good natured razzing, but we have all called one. It makes no sense to harass someone when there mind isn’t 100% in the game! More importantly, this rule does not just apply above the waterline.
A few years ago, I was privileged to complete my cave diving certification, a section of diving which is dedicated to rules that are necessary to have a successful cave penetration dive. Now, years later, nearly every time there is a death in caves, one or more of these rules was broken, frequently by divers with a great deal of experience and practice. It is important to note however, it was likely not the broken rule or rules that lead to tragedy, but complacency that lead them to ignore the rules in the first place.
I won’t tell you that there is never a reason to run out of gas or go into unplanned decompression. I will tell you however, if you refuse to be complacent about the rules taught to you as a new diver, then the likelihood of you experiencing an incident or accident will be greatly reduced.
