What is a Dive Computer?
Simply put, a dive computer is a device that’s used to tell you how much dive time you have remaining in order to dive safely.
Yes, you can use dive tables, a depth gauge, and a dive watch, but dive computers are much easier and safer. It uses a decompression algorithm to calculate and track dissolved nitrogen in your body in real-time when you dive.
Why You Should Own A Dive Computer?
While dive tables have been used for many years, dive computers are quickly replacing them. If you are wondering, “Why you should use a dive computer?” we’ve listed the top five reasons why you should be using a computer.
1
Dive Tables Are Static But Dive Computers Are Constant
A dive computer can provide constant tracking of decompression status. The purpose of using a dive computer is to help prevent diver’s disease or decompression sickness.
It will give you more freedom on your dive because you will be able to constantly track decompression as you descend into deeper depths.
2
It Gives You A Longer Bottom Time
Dive computers can accurately calculate the amount of time you should be allowed underwater because it can take into account the changing depths when diving on multi-level dives.
If you would calculate your allowed bottom time using only a dive table, you would not be able to take into account the amount of time spent at shallower depths compared to deeper levels.
3
They Offer More AccurateTime And Depth Information
One of the hardest things to do when diving is to accurately determine the bottom time and max depth of a dive.
Often, these figures are not accurately recorded making dive table calculations imperfect. If you use a dive computer you can completely eliminate your worries about dive time and maximum depth inaccuracies.
4
They Feature An Ascent Rate Gauge
You know that it is important to ascend slowly from your dive. Going faster than the usual rate of between thirty and sixty feet a minute might increase the chance of experiencing decompression sickness.
While a dive table may tell when you should ascend from a dive, it cannot tell you how fast you are actually ascending when you are diving. Some dive computers, on the other hand, have built-in ascent rate monitors that will warn you if you are coming up too quickly.
5
Dive Computers With Air Integration Have More Helpful Features
Air integrated dive computers provide additional information such as cylinder pressure and the amount of air supply still left.
These can be difficult to calculate in different diving conditions, so having a dive computer with an air integration component is a great safety feature that can help to prevent a running out of air emergency situation.
In concluding, using a dive computer provides many safety features. It allows novice and experienced divers to eliminate the problem of inaccurate information and potential misuse of dive tables.
What You Should Know Before Buying A Dive Computer: Buying Guide
Dive computer today comes with many different configurations and features. It can be a little bit difficult to find the right one. This quick guide should give you a basic idea of which computer will work best for you.
All dive computer is broken down into two major categories, these are:
- Non-Air Integrated – Will not give you any information on the air in your cylinder.
- Air Integrated – Will give you information on current cylinder pressure as well as other information. Air integration can either be wireless or connected by you high-pressure hose.
Next, You will need to decide where you want your Info.
- Wrist Mounted – Allows you to have all your dive information on your arm. This makes it much easier to read and is more streamlined.
- Console Mounted – These are connected to your scuba regulator via the gauge console. Great if you prefer all your dive info in one place.
- Watched Sized – These dive computers are also wrist-mounted but are the size of your typical watch. Many, are quite stylish and can be worn on land without drawing too much attention.
Before choosing a dive computer thou, there are a few things we must consider before making a decision.
What Is Your Diving Level?
One of the first things you should consider is your experience level and finding a computer to match the type of diving you will be doing. The requirements for someone just starting out will be completely different from a seasoned diver.
- Beginner – A simple computer that is both easy to read and use is perfect for someone just starting out. Let’s face it, you’re going to be too busy trying to breathe comfortably and swimming to be messing around with a more complicated computer.
- Advanced – For more advanced recreational diving or tech diving, your needs are going to be completely different. Having features such as multiple gas mixes or Trimix will be more important to you.
Are You Getting Additional Training?
However, if you’re planning on getting additional training then you might consider buying a computer with the feature you will need now rather than having to upgrade later on.
Spending just a few more dollars now can save you hundreds down the line when you realize that you need a more versatile computer.
How Much Can You Spend?
Your budget is also going to be a determining factor when choosing a computer as well. There is no need to look at computers that are way above your spending limit. Knowing what you can spend will help you choose the best dive computer you can afford.
How Often Are You Planning To Dive?
If you are planning to dive only a couple times a year there is no need to get a high-end dive computer. A good entry-level computer will give you all the information you need to stay safe.
Now, If you are someone that dives often, you may consider a mid-range to high-end with more features to make life much easier. These may include features such as air integration, PC or Mac connectivity to download your dives, and color screen for easier viewing.
How Good Is Your Eyesight?
Can you clearly read the data with your mask on? The main purpose of your dive computer is to display critical dive data. If you’re not to read or understand, then it would be completely useless – wouldn’t it?
Let’s face it, a watch-sized dive computer might look great on your wrist out of the water, but if you can’t easily read the information you should consider a computer with a large display. This way you will spend more time enjoying your diving instead of constantly squinting trying to figure out what your computer is saying.
If your eyesight is diminishing, you should also consider a color display. They are generally easier to read than traditional displays.
Where Are You Planning To Dive?
- Locally – If you’re planning to dive locally there pretty much no restrictions when it comes to size and weight
- Travel – If you travel for most of your diving a non-air integrated wrist-mounted computer would work best. That is unless you own a Scuba Regulator of course. This will also you to download all your dive to your computer instead of using pen and paper. It also allows you to dive with your preferred unit of measurement, which can vary from country to country. Watch-sized computers are also ideal for traveling because they are very lightweight, and save more space.
