Zhitiao September 13th news, just last week, Apple 's new product launch conference released a large-scale watch Apple Watch Ultra, focusing on professional sports and extreme outdoor scenes.

is also the first time Apple has launched the Ultra version of smart watch . Unlike the flagship series, in order to meet the needs of professional athletes, the Apple Watch Ultra's extreme mode can last up to 60 hours.

Speaking of his views on this product, senior diver Haje Jan Kamps said: "I am willing to entrust my life to the Apple Watch Ultra."

So, from the perspective of a professional diver, what exactly does the Apple Watch Ultra exactly? What can it do in this scene? We are trying to find the answer.

1. Aim at the largest diving scene, more general than professional equipment

Apple Watch Ultra is designed for casual scuba diving activities with a depth of about 40 meters, and below 30 meters is the location where diving scenes are most frequent.

Oceanic+ will record the diving records of visibility, water flow and other diving that divers are most concerned about during diving. In addition, the app will remind divers not to stay too deep for too long at appropriate times and issue warnings when it surfaces too quickly, and these two features are two important aspects of people's safety during diving.

As a professional diver, Haje Jan Kamps said: "I am looking forward to being able to dive with a smartwatch with a digital crown." Because, most of the recording equipment used by divers are bulky at present, and it will be more difficult to operate after they wear diving gloves.

The advantage of the Apple Watch Ultra is that it is not designed for diving, so its universal features are more powerful.

However, underwater, the watch will lose its signal, but when people return to the water, these functions can be used normally, which is something that ordinary diving watches cannot provide.

2. Incorrect diving methods may be life-threatening

Why is diving watches so important? Let’s start with the dangers people may encounter when diving.

Have you ever heard of diving decompression disease? In layman's terms, when you stay under the water for a certain period of time, after returning to the water surface, the pressure will change rapidly, resulting in the gas dissolved in the body that does not have time to be discharged from the body with breathing, and bubbles form in the tissues and blood. When decompression disease is severe, it can lead to hemiplegia, coma, and even life-threatening.

Previously, this type of disease usually occurred in people working in caves, astronauts and other people, and now, these symptoms often occur in diving activities.

More intuitively, the air we breathe contains about 78% nitrogen , 21% oxygen and 1% other gases. But when you breathe pure oxygen at the bottom of the sea, it will become toxic and may even cause human seizures .

Therefore, in order to ensure that humans stay underwater for a long time, divers will carry compressed air. The air in the scuba cylinder usually contains 78% to 65% nitrogen, which is then converted into gas that can be directly breathed in the human lungs to ensure people's normal movements in the water.

is also the "culprit" that causes divers to suffer from decompression diseases.

is like soda. When you tighten the cap, you will not see very obvious bubbles in the bottle. When you shake the bottle body violently and open it, a large amount of liquid will spray out. Similarly, there is gas in your blood that does not have an effect when it is still, but when you swim quickly from the deep sea to the sea, bubbles in your blood will quickly emerge.

diving watch is to monitor the nitrogen content in your body and issue warnings when people surface too quickly or stay in the deep sea for a long time to ensure people's safety.

3. Cooperate with well-known diving manufacturers to promptly warn of nitrogen content in the body

Specifically, when you dive, smart watches can do several things like this. They can record the residence time at a specific depth when you dive through pressure gauge and clock. Some devices will record once in 10 seconds, and some will record once in 30 seconds. This recording frequency is not critical, and more importantly, it can help you record.

Generally speaking, the smartwatch will record you stay at a depth of 10 meters for 20 minutes, and then help you calculate the duration of the next dive. The best case scenario is that smartwatches used for diving can keep you detailed records at different depths, but so far, many diving watches are not perfect.

Therefore, on the conservative side, divers can only reduce the frequency of diving and spend a lot of time sitting on a diving boat waiting for the nitrogen to be discharged, which is not the best solution to this problem.

Haje Jan Kamps believes that the better way is to improve the smartwatch.

Many people think that Apple's smartwatch can't do it either, but Haje Jan Kamps said: "Apple's smartwatch has performed very well in recording steps, heart rate, exercise, etc.."

However, these functions used for recording are not the key. The top priority of this problem is the algorithm for calculating the nitrogen content in the human body. The difficulty of

is that since the human body structure is different, and the speed of absorption and release of nitrogen by different human tissues is also fast and slow, the accuracy of its recording will be affected.

Therefore, it is very difficult for Apple to design the diving algorithm itself. Apple cooperated with the well-known diving equipment manufacturer Oceanic to develop an application, Oceanic+, which can display the diver's diving depth, drain time and water temperature, and uses Bühlmann's algorithm to judge the changes in nitrogen in the human body.

Conclusion: Recognized by professionals, and the product implementation is clear.

Apple Watch Ultra As one of the major new products of this press conference, it is a product specifically for high-risk, high-intensity professional athletes. This is also the first time that Apple has added an Ultra version to the Apple Watch product line. Before the

product was officially shipped, it had already been recognized by divers in professional sports scenarios. Its performance and design maintained Apple's consistent style. In addition, its linkage with Apple mobile phones and other devices may increase the purchasing tendency of professionals.

When consumers actually get the Apple Watch Ultra, it may trigger a new round of discussion about the product.
