What You Should Know Before Buying A Dive Computer
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 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 in your preferred unit of measurement, which can vary from country to counter. Watch-sized computers are also ideal for traveling because they are very lightweight, and save more space.
