Many bean friends compare "Shark Beach", which I think is unfair. In terms of character, the heroine of "Shark Beach" is not dead, she is just curious, she wants to find the mysterious beach and surfing, not so much; the heroine here, especially the sister Kate, is different, and she has no sense of worry. Di Ye, and she was still a certified Diver, but in the end it was her sister Lisa with zero experience who survived, which was a big irony. As Diver, the fault tolerance of this film is definitely lower. Below I will talk about the diving part of the film from a personal point of view: 1. For those who want to experience diving projects on a zero basis, there are two types: one is holding you with one hand and pressing you into the water roughly until your ears start to hurt ( About 3-4 meters), the surrender is over, usually at most 10-15 minutes, a very unkind, unfriendly and unreliable experience, and it will give friends who are interested in researching an illusion of "I am not suitable". In fact, they didn't take you seriously! Sanya is like that. The second is to have a more professional coach take you into the water (about 10-15 meters), and explain the basic equipment knowledge beforehand, how to breathe, how to balance the ear pressure, etc., which is a more reliable experience. 2. Watching sharks in a cage: I have seen this project in an international charity tourism event. I said that you can participate if you have no experience/ can't swim. There is nothing wrong with the plot, but I am afraid of ten thousand in case. I can’t say 100% there will be no glitches in the movie. 3. Sharks: It's right to attract sharks with fishy blood, because they really don't like human blood and dislike human blood. Most of the accidents that occur are that they feel that they have been violated, accidentally injured, and treat humans as other animals, and generally they will not take the initiative to approach. 4. Kate and Lisa's purpose is not to dive, so they didn't wear a dive computer (a type of diving watch), they were thinly dressed, and they didn't have fins. All of these are correct. －－－－－－Well, the reasonable plot ends here. When the failure occurs, the Divers will do error correction questions on the Shanggang line.－－－－－－ 1. 47 meters: General amateur licensed players are only allowed to dive to 30 meters. The reason is that the deeper you dive, the more oxygen you need to breathe, and the faster the oxygen consumption. If you want to play underwater as much as possible with a limited amount of oxygen (200bar an ordinary gas cylinder), you must control the depth; And the deeper the depth, the colder the sea water, and the water temperature is completely different with a difference of only 1 meter. In order to be safe, the body must not lose temperature, and the depth must be controlled. Due to the unbalanced ear pressure, you have to sink slowly after entering the water, otherwise the ear pain is really painful, so the film quickly sinks to 47 meters, the eardrum must be exploded (I feel pain only by fantasy), Lisa can still be Kate Wake up, great. 2. Impact: Usually the breathing head (oxygen inhalation) for diving is a bite type. In the film, this is for the plot to make them speak, so after the impact, they fainted. As long as the mask does not fall off, the cylinder is not broken and the neck is not broken. It is still possible to live. I have seen some accident reports and are very professional divers. They only fell into the bottom of the sea (sad) after only a slight impact + fainting + biting respirator head fell off. 3.55bar: For the sake of safety, generally the cylinder should be ready to land when there is 20-50bar left, so after Kate came out of the cage, the signal was connected to the old man, and he asked Kate to go back to the cage and wait and say that he would not be attacked by sharks. I started rolling my eyes when it was safest. Brother, don't you know how many bars can stay at 47 meters for a few minutes? You arrange for someone to go down and look for it and avoid the sharks. At this point, they have already run out of oxygen. Did Kate get a fake certificate? Pawn, the end. 4. She removed the stone and the heavy object, 10bar is gone, Kate, as a licensed launcher, can take her sister to ascend, 10 meters and 5 meters to make a safety stop, no injuries, there will be no Decompression sickness, perfect. Believing in the ghost of the old man, let them stop talking about decompression sickness. After all, is decompression sickness important or life? 5. After returning from the basket, Kate started chatting with Lisa. I laughed out loud in the theater on the spot, and I was really poked. We can't use the bar count as fast as we can talk, these two people are not afraid at all. 6. Buddy system: The most important thing about diving is whether you can do it alone. Kate went out alone to find the signal and ignored it. Later, Kate didn't get angry and asked Lisa to go out to find their rescuer. Lisa kept calling Im lostlostlost. I think the visibility at 47 meters is not high, and it must be lost to find the way back. Pawn, the end. According to the director's settings, the sisters will undoubtedly die. In the end, Lisa's fantasy turn was quite wonderful. If she was not successfully rescued, it would be more educational and reasonable. I didn't define it as a sci-fi movie, so I am more of a thimble, and I hope to share what I have learned with everyone. Finally, it is recommended that this film be included in the PADI negative teaching materials.
