It is hard to imagine that dive computers didn't exist 15 years ago. , but dive computers did not exist 15 years ago. Up until the first reliable multi-level dive computer appeared in the late eighties, a diver had to rely on the U.S. Navy dive tables or similar tables. Dive tables were originally designed for divers who were going to dive to a single depth, stay at the depth the entire dive, and return directly to the surface. The dive tables may have worked fine for a Navy salvage diver, but a recreational diver's depth varies throughout the dive. The recreational diver needed a device that could recalculate no-decompression time on the fly while diving, and calculate available no-decompression times for future dives while on the surface. Fortunately, advances in microchips, sensors, and other electronic components made it economically feasible to build affordable recreational dive computers. At the same time, some of the brightest decompression scientists had developed decompression algorithms that could be programmed into a microchip. Hence, the dive computer was born. Suunto's SME-ML was one of the original dive computers ever made, and there are many still in service today!
How Dive Computer Works
A dive computer has five main components:
- 1 A power source
- 2 A timer to measure elapsed time
- 3 A pressure sensor to measure depth
- 4 A microprocessor to perform all the calculations
- 5 A liquid crystal display (LCD) to show the user all the information.
HISTORY:
In the early 1980s, it wasn't common to see divers using dive computers, though it wasn't unheard of. By the end of the decade, however, the majority of divers who dive frequently were using them. Though divers still learn to use dive tables as a method for establishing decompression concepts and for calculating dives in the event of computer failure, today dive computers are the rule, not the exception.
The decompression models dive computers use are essentially the same as those used to create dive tables. Dive computers simply write a custom dive table for the exact dive depths, times and surface intervals, affording more dive time than tables by eliminating unnecessary rounding.
Dive computers do have some differences in the way they calculate. You can group computers into three basic groups:
1. spencer limits, EE washout
2. spencer limits, 60 minute washout
3. buhlmann limits, EE washout
Computers within these three groups identify the broad characteristics of how they calculate repetitive dives.
Features of a Dive Computer:
Why should a diver use a dive computer? Why not use the tables I learned in my open water class? Well, there are a couple of reasons: A dive computer eliminates human error and it increases the value of every dive trip, even the weekend beach dive.
By eliminating tables, you prevent the possibility of human error. If you only dive occasionally, it is very possible you can forget how to use the tables. After three or four dives, you may be tired and make a simple mistake in math, or forget to log important information needed to properly calculate dive tables. A dive computer never gets tired and never forgets. Your dive trip becomes more enjoyable because you are spending time with your friends and not your dive tables.
Unlike dive tables, dive computers credit you with more bottom time as you ascend from your maximum depth; therefore, dive computers make more economical sense, even if you only take one dive trip per year. Let's say that you use dive tables on your $1000 dive trip. On that trip you totaled 400 minutes of bottom time. That comes out to be $2.50 per minute. If, on the same trip, you used a dive computer and got 800 minutes of bottom time, that's only $1.25 per minute! In essence, you have doubled the value of your trip; the computer paid for itself several times over.
Selecting a Dive Computer
The computer that is best for you will depend on the type of diving you do. There are two main types of computers - non air-integrated, and air-integrated.
Non Air-Integrated Dive Computer
These are the most common computers and are usually sold in gauge consoles with a submersible pressure gauge, or as stand-alone modules that can be installed in hosemount or wrist consoles. When shopping for this type of computer, you want to make sure it measures and displays these basic pieces of information: current depth, no-decompression time, maximum depth, bottom time, and ascent rate. Another important feature is automatic activation. If you ever forget to turn the computer on before making a dive, the auto-activation feature turns the computer on immediately upon entering the water. All Suunto computers have this feature.
Enhanced Features of Dive Computers

upload all of your dive
profiles to your PC and keep
an electronic logbook.
- Pre-dive planning that
allows you to view nodecompression
limits for
the next dive.
- User-changeable batteries

instant status of the dive
without even looking at the
numbers.
Dive simulator that allows you to plan an actual
dive profile based on your current residual
nitrogen from previous dives.
- Nitrox features that allow
you to program in the
oxygen content of your
breathing gas and the
oxygen partial pressure
(PO2) limits.
- Audible alarms that alert
you to potentially dangerous
situations during the
dive.
- Time and date feature that
will be displayed before and
after the dive and will be
entered into the logbook
memory.
- Temperature feature that
displays water and air
temperature and is also
recorded into memory for
entry into your logbook.
Though decompression diving is not recommended for sport divers, most computers will calculate decompression stops and total ascent time to the surface, which includes all the decompression time and time it takes to ascend from depth.
Air-Integrated Dive Computer:
This type of computer includes the features mentioned earlier, but also includes an electronic device called a high-pressure transducer that measures air pressure from your cylinder. High-pressure transducers are much more accurate than analog pressure gauges and can display pressure in increments of 10 psi or less. Since the air pressure information is electronic data that can be used by the computer's microprocessor, the computer can measure your breathing rate and calculate remaining air time.

Dive computers address the same problem as decompression tables, but are able to perform a continuous calculation of the partial pressure of inert gases in the body based on the actual depth and time profile of the diver.[1] As the dive computer automatically measures depth and time, it is able to warn of excessive ascent rates and missed decompression stops and the diver has less reason to carry a separate watch and depth gauge. Many dive computers also provide additional information to the diver, for example, the water temperature, information on the diver's oxygen toxicity or the pressure of the remaining breathing gas in the diving cylinder.
Dive Computer can also help you plan your diving and scuba adventure from start to finish. We cater to expert divers, professional divers, beginner divers, amateur divers, dive trainers and even complete dining parties that include family diving and buddy diving with the most invigorating diving tools.
Because of the computer's ability to continually re-calculate based on changing data, the diver benefits by being able to safely remain underwater for longer periods of time using an equal volume of gas. For example, a recreational diver who plans to stay within "no-decompression" limits can in many cases simply ascend a few feet each minute, while continuing the dive, and still remain within safe limits, rather than adhering to a pre-planned bottom time and ascending directly. So-called multi-level dives can be planned with traditional dive tables, but the additional calculations become complex and the plan may be cumbersome to follow. Computers allow for a certain amount of spontaneity during the dive.
