"According to what Rob said, Fisher's team set off at the same time as us. We have encountered them before. They are right behind us. Their people should be very close to us, and the vertical distance will not exceed one hundred meters."
Bi Fang fiddled with a tiny instrument and adjusted the signal mode, changing from transmitting to receiving.
"You should have seen that when entering a dangerous zone, you must have all the emergency tools ready. If not, choose a reliable guide to take you. Even if you may be a novice mountain climber, at least there will be experienced people to help you understand this aspect.
Knowledge."
[Aren’t you here to watch Lao Fang’s video (dog head)]
[You think I’m here to watch the live broadcast? Superficial! I’m here to learn knowledge!]
[Brother, your online name is very familiar. Have you met me in Huya? Is this also learning knowledge? 】
[Of course, isn’t the purpose of removing tiger teeth just to learn advanced mathematics derivation? Is there any problem? No problem. 】
"Altitude recorder, blood oxygen recorder, and now the avalanche detector I'm holding in my hand."
"Avalanche detector, also known as avalanche search and rescue instrument, avalanche beacon. Transceiver, beacon in English, also known as ARTVA, DVA in Europe. It is the main tool for finding victims buried in the snow. The detector is divided into launch and
There are two reception modes, and detectors of different brands can basically be used universally.
Generally, before setting off to the snowy mountains, everyone turns on the detector and switches it to launch mode. This is so that when someone is buried in an avalanche accident, the detector can be used to search and locate, and then the probe rod can be used to accurately locate it, and then the snow shovel can be used to dig.
Bring out the buried."
"The physical principle of this thing is to emit and receive an electromagnetic wave modulated signal with a frequency of 457kHz. Search and rescue personnel can judge the distance from the buried person based on the distance displayed by the detector, the intensity of the signal light, and the intensity of the sound.
The range can basically be determined within one square meter.
Then we used a probe rod to accurately determine the location and depth of the buried person. Finally, we used a snow shovel to quickly dig out the buried person, but our equipment was lightweight and we only brought a detector."
But before looking for someone, I first have to try to see if we can find our drone. Mine and the one from the Jarrett program group are also equipped with signal transmitting devices. Last night, one of them hung above our heads. It should be
It's around here, but it's possible it was washed down below."
Bi Fang's drone was given by the system and was completely controlled by his mind. However, sometimes in order to cover up others' eyes, Bi Fang would operate it "manually". It was currently buried, but he could still sense that it was nearby, but Jarrett's
The drone does not have this function, but fortunately it is equipped with a signal transmitter.
"If I lose it, I'll be doomed. The cost of a custom-made drone is only 400,000 U.S. dollars. I hope it won't be deducted from my salary." Jarrett was a little downcast.
[F*ck, three hundred thousand dollars, this damn thing, even if I sell it, I can’t even afford it]
[Where do you think such high image quality and battery life come from?]
[Indeed, it’s almost six thousand meters and you can still fly, it’s all about money]
[To be honest, technology is quite advanced now. As long as you have money and materials, you can build a black-tech drone for you]
Bi Fang patted Jarrett on the shoulder and laughed: "It's okay. It's the greatest luck that someone is okay. If you really want to pay for it, I will take care of it when the time comes."
Press a few buttons and the detector responds immediately.
Bi Fang took a few steps cautiously, and then
"Hey, right here?"
Bi Fang was a little surprised that Jarrett's drone was not swept away.
Hearing that his drone was at his feet, Jarrett became excited: "Quick, quick, we're digging!"
The group of three people immediately took action.
"Damn, this piece of snow is so hard." Yao Jun dug for a long time and finally lifted a large snow piece with great difficulty.
Bi Fang also joined in. After two or three hours of recovery, although his muscles were still a little sore, it no longer affected his activities: "No way, the avalanche snow itself may be a relatively solid snow block, and when the avalanche fragments finally stopped,
A large amount of kinetic energy will produce a compression process, resulting in hard accumulation of snow. Therefore, many teams will bring snow shovels, but it does take up space to carry things. Wait, I am going to make a tool. Did I bring too many crampons?"
"Bring it." Yao Jun found the crampons from his backpack and handed them to Bi Fang.
Digging snow with hands or snowboards is extremely inefficient or even impossible.
According to statistics, the average time it takes to use a snow shovel to dig out a completely buried person is about ten minutes.
If you dig with your hands and snowboard instead of using a snow shovel, it will take about an hour to dig out. So when you are trapped in a confined space, it still takes more than an hour for so many people to dig.
However, when it comes to digging holes, it’s hard to use a shovel, and it can’t even be wielded, so it’s better to dig by hand.
Bifang came to the side, took out the lifting rope from his backpack, cut off a section, and then took out the spare crampons.
"The head of the crampon is serrated and very sharp, but the middle part is hollow. We can use it by wrapping the middle part with a rope, and finally fix it on the trekking pole, and a simple snow shovel is made."
Bi Fang wrapped the rope around the spare crampon in circles. When it was in the third position, he wrapped it in together with the trekking pole. At the same time, it wrapped it back and forth in the gap between the crampon, and then the position of the heel of the crampon was in line with the climbing position.
The stick is formed into an X shape so that it will not move left or right and come off easily.
Soon a simple snow shovel took shape.
[A snow shovel or something, is it necessary? No need]
【Easy to make】
【Real DIY!】
【Excavation!】
After making the second one in the same way, Bi Fang and others dug much faster.
When the signal was the strongest, Bi Fang stopped everyone's movements: "Okay, we are very close. Be careful not to destroy the drone."
Jarrett was the most anxious and was the first to throw away the shovel and start digging the hole. Soon, the black drone revealed its propeller.
"Come out, come out!" Jarrett carefully took the drone out.
"Let's see if it works."
The photographer who had been paying attention at the base camp saw the drone being dug out and immediately started to control it. Soon, the snow-covered propeller rotated rapidly, throwing everyone covered in snow, and flew up swayingly.
gradually stabilized.
The audience who had always maintained the first-person perspective suddenly found that the perspective changed to a high-altitude perspective.
【Yes! Yes!】
[It’s still comfortable to read in the third person]
[First-person stimulation is exciting, but it’s a bit boring to watch at ordinary times]
The audience cheered and found Jarrett's drone. Bi Fang pretended to search and successfully found his own drone.
"Finally I can see your comments again. The one-sided communication makes me feel like no one is listening in class."
After letting the drone take off, Bi Fang was finally able to stop pretending and led everyone down the mountain quickly while checking to see if there was any signal from the detector.
But when he came to an ice crevice, the detector had not responded yet, but Bi Fang made a discovery and his nose twitched slightly.
