Underwater Safety Considerations
While exploring the underwater domain can prove to be one of the fascinating experiences to ever behold, it is just as dangerous. The unmapped territory and the thrill of the unknown are what drive people to spend as much time as possible as often as they can underwater, but they must take a lot of safety precautions when doing so as the water can truly be a cruel mistress to those who are unprepared.
No matter how experienced you are, if you are an entry-level diver or a professional, one gear you should have on you at all times is the diving computer. It prevents decompression sickness and it helps guide you when it comes to the right amount of time you should spend underwater so that all decisions you make when diving are informed and based on precise calculations. It might be a small device, but it really packs a punch, that’s for sure.
We have already explained how the wearable works, so you are aware of why it is trustworthy and just how much more it makes your life easier as it takes complicated calculations off of your hands. Instead of having you slave for hours figuring out how long the diving session should be and how far or deep you should go, it displays in a matter of seconds the information to keep you updated with your situation. Taking into consideration the fact that it automatically picks up time and pressure, safety is further enhanced as these are parameters you are unlikely to guess with a high level of precision on your own before starting the expedition.
| Criteria |
Impact/Importance |
Best Product |
| Water Resistance |
The water resistance rating shows what is the maximum depth you can reach while wearing it. Obviously, for an experienced diver, it is better for the maximum depth to be bigger, while a beginner could just as easily go for a device which does not allow him/her to go further underneath. |

| Operating Temperature |
Another important rating element which influenced our depiction of the best products in this niche is operating temperature as this stat shows under what conditions the device can be used. Obviously, it is best for the temperature range to be more generous in order for the device to be dependable in all situations. |

| Log Book Memory |
The memory of the log book shows how many hours can be stored on the device. When the limit is reached, you must transfer the data in order to not lose it, or delete it completely in case you are not interested in saving it for further evaluation. |

| Backlight |
The backlight allows you to see what info is displayed on the screen with ease even when there are very poor lighting conditions. Seeing how the underwater environment is quite different than the above ground one, poor lighting being an often occurrence, this is a vital feature. |

| Audible Alarms |
Audible alarms are triggered in situations where your attention is needed as it is time to ascend or something else has happened.

- Continuous Decompression Status Tracking
The main purpose is to help you avoid decompression sickness, an uneasy feeling that makes some people stay away from underwater diving for long periods of time as it scares them. Tracking your theoretical in-gassing and out-gassing of nitrogen based on your body, it tracks all the important parameters throughout the changing depth of the diving session to prevent the sickness that accompanies decompression.
- Accurate Recordings of Depth and Time Parameters
One of the biggest challenges you are confronted with is accurately calculating the maximum depth and bottom time. Unfortunately, as you do the table calculations a lot of inaccuracies can occur. As you use it, this concern is eliminated as the device constantly and accurately records maximum depth and diving time, faulty info not existing anymore and your experience underwater becoming safer.
- Easy to Understand Ascent Rate Indicators
The ascend rate varies from one situation to another, divers being instructed to ascend slowly as the table prescribes for maximum safety. Usually, the ascension rates range from 30 to 60 feet per minute, being mandatory for you to stick to them in order to avoid decompression sickness. Alas, the table is not dependable from this point of view as it does not provide accuracy, and it cannot predict the profile of the diving session. However, computers feature ascent rate monitors and warning devices which enable a smooth ascend each and every time you descend, thus enhancing safety.
- Elimination of Errors
Errors can easily occur when you are using the table as you might tend to forget how to use it and do the proper calculations. Seeing how with the calculator you are not performing the calculations yourself as the device tends to this operation, automatically taking into consideration the decompression status as well, errors will no longer exist and you will have more fun when diving.
Making the right pick is not as easy as it seems. In theory, the wearable might have the role of making your life easier by eliminating the need for you to do any calculations, and it might considerably enhance the safety of your diving sessions, but this does not mean that all devices are alike and that their performance is equally impressive. Obviously, you would not want to take chances and end up with a decompression computer which does not perform as expected, reason why we put together a comprehensive buying guide for you to follow. As long as you answer these questions before you go shopping and keep your answers in mind when you make the ultimate pick, you will be pleased with your option for sure.
- What Is My Diving Level?
Clearly, the first question you must ask yourself and answer to truthfully is what diving level you are at as the entire design of the device depends on this question. If you are a beginner or a hobbyist, a simple device is a right choice as you will not have to waste time underwater figuring out what the abbreviations on the screen stand for. On the other hand, if you are an experienced diver, it must come with more advanced features like trimix capabilities, for example, enhancing your experience when you are underwater.
- Is It Easy to Use?
Regardless of your diving experience, one thing is for sure – you do not want to end up with a device too hard to use and that will have you waste time switching between settings and operational modes. Thus, you must be on the lookout for a user-friendly design and interface. One of the main highlights of a simplistic device is a big display that does not use intricate abbreviations, and easy to press buttons which allow you to toggle between selections even when wearing thick gloves.
- Can It Operate When There Are Harsh Temperature Conditions?
Sometimes the water will be quite friendly temperature-wise, while at other times it will feel like it is freezing. Make sure that the model you do pick can withstand colder temperatures as well as normal temperatures, as you surely do not want to have to cut your diving session short because of this circumstance.
- Is It Easy to Read the Displayed Info Underwater?
Seeing how the environment underwater is completely different than it is above ground, you have to take into consideration the fact that there will likely not be the best lighting conditions at all times. Thus, you will not have an easy time reading the data off of a small screen. To make sure you will be satisfied with your purchase, you should go for a model with a wide-size screen onto which information is clearly displayed.
- How Much Am I Willing to Spend On It?
Of course, you must set a budget before you start browsing to make your life a bit easier. This way, you will eliminate products that are way above your pay grade, and you will have a more realistic look at what models you can and cannot buy. While these devices are more than important for scuba divers, this does not mean you have to sacrifice too much when purchasing one as a cheaper product could be just as great performance-wise as a more expensive one. Just take your time, do the proper research, and you are sure to find the right one for you.
Frequently Asked Questions
?How does water resistance factor in the overall performance of the product?
Water resistance is actually one of the first specs you should check out when making the purchase as it basically tells you under what circumstances you can and cannot use the device. If the water resistance rating of the product is 120 meters, for example, this shows that you should not exceed this depth limit when you are underwater as the device will not be able to support it and might receive irreparable damage.
?What is the average life of the device?
On average, the device lasts for 1-2 years, or from 300 to 500 diving sessions. Obviously, the lifespan differs from one model to another as well as from one user to another. The amount of times you use it basically influences its lifespan, regardless of the model in question.
