Points to consider before buying the right Dive Computer Watch
There are a number of important factors to be considered before investing in the right dive computer wrist watch, considering the fact that there are a number of competing models available these days. Some of these factors are discussed here.
- Experience of the diver
- Ease of reading
- Ease of Use
- Compatibility with Nitrox
Experience of The Diver
There are hundredths of dive watches model available in the market under different categories, there are some designed for beginners with basic features and some watches hold the most advanced features that would appeal to the experts. Advanced watches used specific software to connect with computers and store all dive relevant information for further reference and to keep history of the dive log.
Ease of Reading:
Beginners should choose consoles that are easy to read and the screen should not be cluttered with too much information. Back lit displays with big numbers with audible alarm system also would help them to read critical information easily and dive safely. Some models of these dive watches are able to display information in multiple languages so as to appeal to beginners.
Ease of Use:
Though these dive computer watches are tough piece of hardware to be associated with the diver, majority of their function is based on their software. Some work on simple Bluetooth technology, while others on firmware and even on some advanced software.
Some of them are user friendly while others need some advanced knowledge to read through them and could be pretty tough for beginners. Also the type of watch one chooses depend on the type of diving they perform. For diving in cold waters where the diver would wear thick gloves, he has to choose a watch with bright display visible even through the glove.
Compatibility with Nitrox:
Nitrox compatible dive watches are important for professional divers as it would help in choosing the level of nitrogen concentration for the dive. These watches would help in regulating the limit of the depth of the ocean they could dive and calculate the level of decompression depending on the percentage of nitrox used in the dive.
Check The Dive Computer For Digital Compass
It is important to check the model for the availability of a digital compass though most of the models these days are featured with it. Digital compass are important tools to ascertain the direction of the diver under water. The compass should also be adjusted every time the batteries are changed and when it is exposed to magnets of any form.
- Saving log data
- Cost Considerations
The battery power is directly proportional to the specifications in it, more the specs more is the battery consumption. It is important to choose watches with a high battery power or to choose devices with options for replaceable or rechargeable batteries. Most of the high end models come with options to recharge the batteries using a USB charger.
Saving Log Data:
Some of the advanced dive computer wrist watches are featured with the ability to transfer dive data directly to the cloud or at least to the PC. Transferring all important data helps to maintain constant dive record and is measuring the track of dive performance. Some advanced features that could be recorded and maintained as the ascent rate, amount of air consumed and also the percentage of nitrogen concentration.
Dive computers could cost anywhere between $100 and $1000 depending on the specs they offer. It depends on the budget of the person to choose the best fit model based on their requirements, type of dive and their level of expertise. With little research and patience it is possible to fit a watch with decent specs and within a reasonable price point.
How Does Dive Computer Wrist Watch Work?
Having gained information about the best Dive computers wrist watch, we need to ascertain why these watches are important for divers, what its significance is and how it helps them with safe diving.
The ocean is a mixture of different gases and is not predominant with oxygen as though with the atmosphere. In fact, oxygen concentration is very less below sea level and nitrogen gas is predominant in the ocean. When a person gets under water, this nitrogen gets absorbed into their body, though the rate of absorption differs depending on various factors. The rate of absorption of nitrogen increases with the depth the ocean and longer the absorption greater is the risk.
The absorption of nitrogen is measures in term of half-life period which is the measure of the time take by the body to release half of the nitrogen that is been absorbed. This half-life period is denotes in minutes and the moment the diver gets under water, this dive computer wrist watches would calculate both the time and the pressure along with the saturation of nitrogen in the body.
They then display a number of important parameters such as oxygen saturation, nitrogen levels etc. to help the person have a safe dive. The good news is that these dive computers are available in the form of wrist watches, which makes them easy and convenient to use on the go.
Types of Dive Computers
Dive computers of modern days are features with a number of different configurations which makes the diver choose the best one. Basically, there are few categories of these dive computers to help the diver choose the best one based on his level of expertise and his experience.
- Non air integrated wrist watches would not give any relevant information about the level of air in the oxygen cylinder
- Air-integrated watches will accurately predict the cylinder volume and pressure.
- Air integrated watches could either be wireless or connected to the diver with the help of a high pressure tube.
- Wrist mounted watches behaves like a traditional watch on the arm. All dive related information is streamlined and it is easier to read all dive information by a simple twist of the arm.
- Console Mounted watches are connected through a gauge console with the scuba regulator.
- Watch sized consoles: These dive computers are exactly the size of a normal watch and are mounted on the wrist. They could be used on land as well as normal watches without drawing much attention from the on-lookers.
Dive computer wrist watches are important tools for divers irrespective of their level of expertise as it helps them to track key metrics associated with their life such as nitrogen concentration.
They help them with the direction they need to swim along and informs them about the pressure level under water and the level of their oxygen concentration. And most importantly if something goes wrong, then they alert the diver with their alarm system.
The above mentioned Best 6 dive computers wrist watches serve as excellent companions for divers and display all key information for their safe dive within the reach of their wrists.
