Diving computers, like divers' brains, are often ignored by some people, and some even claim that you don't need to wear a computer watch to dive in open waters.
In this regard, the owner's mood is like this:
Not wearing a submersible computer means that the current water data is not accurately measured, the decompression-free time is not accurately understood, and the rising speed is not accurately controlled.
Under such circumstances, the chances of suffering from decompression sickness, oxygen poisoning and nitrogen anesthesia are greatly increased!
This is to turn one of the most exciting extreme sports into "the most complicated suicide sport"!
Based on the principle of "worrying about the world first" and "putting people's lives and property safety first", the owner specially made the ultimate comment on the first phase of the diving computer watch!
Scope of this evaluation: Covering diving computers that divers at home and abroad like.
This evaluation index:? Appearance, comfort, information and cost performance.
Selected products this time: Suunto zoop novo, Suunto D4i, Shearwater Perdix SA and Oceanic OCI.
The owner will try his best to let all divers who have won OW and AOW find the most suitable diving computer for them.
1.？ Suunto zoop novo
Zoop novo, which was launched in 16, has been widely praised by the market as an entry-level product of Suunto family. If the old bird recommends the diving computer to the newcomer, the old bird is likely to jump out of zoop novo.
Zoop novo adopts a four-button menu interface. Compared with the old zoop, it has been upgraded and optimized. Generally speaking, the colors available are bright green, yellow, blue and black. The mirror material is acrylic, and the strap material is synthetic rubber. The appearance is bright and cool. The dial with a diameter of 66. 1mm is huge. Compared with the old one, it has increased the backlight function. The underwater operation is simple and fast, and all kinds of data are easy to read, which increases the diver's sense of security in disguise.
However, the huge volume also makes it very inconvenient to wear at ordinary times. In addition, some problems such as hard buttons and rough workmanship are inevitable.
Zoop Novo is equipped with five diving modes: air, high oxygen, instrument, free and closed. Four kinds of sensors: barometer, pressure sensor, altimeter and compass, with functions covering surface time, rising time, deep stay and safe stay. It can be said that it is more than enough to cope with leisure diving.
It is worth mentioning that the data cables of zoop novo and the old zoop are not universal, and it still costs a certain fee to purchase the original data cable separately. However, this should not be a big problem in the face of the ultra-low price inside zoop novo 2000.

2.Suunto D4i
The second diving computer is also the product D4i of Suunto, Finland. The position of D4i in the domestic diving market is basically the same as that of iphone, even if it does not reach the point where everyone has hands, it is not too bad. Basically, you go diving in Xianben. When you see D4i, you can say, "Wow, you must be from China!"
Closer to home, D4i also adopts the 4-key menu style, and the surface material is mineral crystal glass, so both crystal and glass are made of silicone, which is greatly reduced compared with zoop novo, only 48.6x43.8mm .. This has caused a very real problem. Many people complain that the digital reading is not clear on the limited surface size. On the other hand, it is not so abrupt to wear in life. Rich in color, but the shape is quite satisfactory. It can be said that D4i is conservative in appearance.
D4i provides four modes: air, high oxygen, free and closed. It uses a completely continuous decompression algorithm (Suunto RGBM) to calculate the decompression of diving, and has built-in timers of various modes and a diving planner. Compared with zoop novo, the wireless transmission function of indicating the residual pressure of gas cylinder is added, and the current tank pressure and residual air time can be read.
The terrible thing about D4i is that it doesn't support replacing the battery by itself. Although it is a DIY with strong hands-on ability, hehe, exporting data is indeed more convenient than zoop novo. As a product of 4000 yuan, the cost performance is good.

3.Shearwater Perdix Limited
Shearwater Perdix sa, the legendary "one-step" choice.
Canadian factory Shearwater needs to talk about it. They started with CCR controller, and later heard that they started to make stand-alone machines because of the pleading of customers. This is a bit equivalent to starting a class to teach Dugu Jiujian, and then starting to teach Zama Bu. The technical strength should still be very good.
Adopt plastic casting, acrylic panel and double button design. The owner personally feels that the appearance is very black and domineering. It's very professional and nb. Of course, you can't wear it at ordinary times, otherwise you will be easily arrested near Tiananmen Square. The brightness of led screen can be adjusted by ambient light source. At the same time, in order to ensure the normal work of the pressure sensor, a honeycomb pattern is adopted on the back, and four positions are reserved for bungee jumping. Finally, change the problem of the old product!
With ZHL- 16c decompression algorithm, you can upgrade to VPM decompression algorithm for a fee. Five diving modes are provided: open system, circulating system, high oxygen, and three mixed closed. You can preset any proportion of oxygen, nitrogen and helium, adjust the conservative value of decompression model, support negotiation mode, customize the interface display content, support mobile phone app, and support battery replacement.
I'm tired of writing. I don't know if you are tired of watching it. Perdix crossed the threshold of leisure diving and went to technical diving.
Abnormal information is prompted in red and yellow, which is very eye-catching on the black and white dial. In addition, you can upgrade and purchase Shearwater Perdix AI version to support gas cylinder pressure sensor.
If anything, this thing really looks big and heavy, and it's not very convenient to carry. However, as everyone said, "the planet is the best shallow brain", and the master said that I can bear this weight! At the same time, its price between 5000-6000 yuan is also quite expensive.

4. Ocean OCI
If Suunto's main battlefield is in China, then Oceanic's main battlefield is in Europe and America, and domestic people generally don't know much about this diving computer.
The OCI body is made of carbon alloy, and its appearance is still very domineering. Although it is also a traditional four-button control, the ironing design will not fall in the wind when worn.
However, the biggest feature of OCI is its functionality. It has two decompression modes to choose from (ocean DSAT or ocean Z+), and also has many modes such as air, hyperoxia, instrument, free and technical free diving. In addition to the necessary functions, OCI is also equipped with a wireless transmitter, which has the function of wireless transmission and reception. In addition, it is equipped with a digital compass, which can adjust the magnetic declination.
In the field of high-end shallow brain, it can be said that OCI and Perdix compete.
The most intimate thing is that Oceanic designed this watch so that you can pack a wave when you buy it. Watches are intimately equipped with functions such as stopwatch, alarm, time between two places, countdown, etc., plus the design of taking care of daily wear, it is no problem to make daily watches on land.
The problem is that this watch is really expensive ... the price has reached its peak, and the highest evaluation is more than 8,000 yuan. ...

For a diving computer, everyone has their own best choice. But in any case, the product level should match the difficulty of your diving activities. If you save your wallet, but you put yourself in danger underwater, it's totally worthless.
