Dive Computers vs. Dive Tables

Picture this – I’m riding to the dive site in my horse and buggy, and calculating my no decompression limits on my abacus. If you think that takes time, that’s nothing, it’s chiseling my dive plan into my stone tablet.

Simple Rules To Dive By

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.

Open Water Certified, Now What?

There is so much out there with continuing education, sometimes it can be a little bit overwhelming trying to choose what the next steps should be. A lot of it may also depend on the region you live in and what your local dives may entail. The bottom line is… the adventure has just started.

Scuba Diving – How-to-Guide to be a Certified Diver

diver_stingraySo you’ve been dreaming of exploring the peaceful underwater world, drifting weightlessly with the fish and turtles, dancing with dolphins, and gliding effortlessly with the rays.  That dream can easily become a reality and here’s how:

  1. Contact your local SDI dive center and sign up for your Open Water Scuba Diver Course.  You can use Scuba Diving International’s dive center locater found here.
  2. Once you have chosen your dive center, you can start the home study portion to prepare for your course.  This can be done with either the traditional manual, or the more popular online eLearning course.  This will provide all of the basic knowledge you will need to begin your underwater adventure.  This information will then be reviewed with your scuba instructor where they can answer any questions you may have and correct any questions you might have missed.
  3. Your next step in becoming a certified diver is to complete your in-water skill development training with an instructor.  This will take place in a swimming pool or similar body of water.  This confined water session is where you will learn and master the basic skills required for the underwater world.  Skills including equipment set up and use, buoyancy control, proper swimming techniques while wearing SCUBA, regulator and mask clearing, proper ascents/descents, as well as emergency procedures will all be covered and practiced until you are proficient and comfortable in the water.
  4. The final step of your certification process is to test your skills in open water.  Here you will apply what you have learned during your academic and skill-development sessions, while learning practical lessons that can only be gained through real-world experience in open water. This portion of the course will include a minimum of four open water dives, where you will demonstrate your ability to plan and manage dives under the direct supervision of your instructor.  These “check-off” dives can be conducted locally with your dive center, or while you are on vacation in a tropical paradise.
  5. Get out there and DIVE!  Scuba Diving grants you access to a whole new world, what adventure awaits YOU below the surface?

Here is a list of some basic scuba gear to consider for your recreational dives. Talk to your instructor about what tools to consider for your course!
