"According to Rob, Fisher's team set off at the same time as us, and we have met before, just behind the butt, and their people should be very close to us, and the vertical distance will not exceed a hundred meters."

Bi Fang fiddled with a tiny instrument, adjusting the signal pattern from transmitting to receiving.

"You should have seen that when entering a dangerous area, emergency tools must be prepared, and if you can't, choose a reliable guide to take you, even if you may be a novice mountaineer, at least there are experienced people to help you understand this knowledge."

[Isn't this coming to see the old party's video (dog head)]

[You think I'm here to see the live broadcast? Shallow! I'm here to learn! 】

[Brother, your screen name is very familiar, have you met it in Tiger Tooth? ] Is this also learning? 】

[Of course, isn't it to learn the derivation of high numbers? Is there a problem? No problem. 】

"Altitude recorder, blood oxygen recorder, and the avalanche detector I have in my hand right now."

"Avalanche detectors, also known as avalanche search and rescue instruments, avalanche beacons. 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 two modes: transmitting and receiving, and different brands of detectors can basically be used.

Generally, before setting off for the snowy mountains, all the people turn on the probe and turn it into launch mode. It is so that when someone is buried in an avalanche accident, the detector can be used to search for and locate, and then the probe can be used to accurately locate the person, and then use the snow shovel to dig out the buried person. ”

"The physics of this thing is to transmit and receive a signal modulated by electromagnetic waves with a frequency of 457kHz. Search and rescue personnel. According to the distance displayed by the detector, the strength of the signal light, and the strength of the sound, the distance to the position of the buried person is judged. The range can be basically determined within one square meter.

The probe is then used to pinpoint the location and depth of the buried. Finally, a snow shovel was used to quickly dig out the buried, but we were lightweight and only had detectors. ”

But before looking for someone, first I have to try to see if I can find our drone first, mine also has the Jarrett program team, which is also equipped with a signal transmitter, it hung above our heads last night, it should be around here, but it may also be washed down. ”

Bi Fang's drone is given by the system, and it is all controlled by the mind, but sometimes in order to hide people's eyes, Bi Fang will operate it "manually", and it is buried now, but he can still sense that it is nearby, but Jarett's drone does not have this function, fortunately it is equipped with a signal transmitter.

"If you lose it, it's over, and the cost of that customized drone is 400,000 ugly knives, and I hope it won't be deducted from my salary." Jarrett was a little frustrated.

[, 300,000 knives, this, I can't afford to sell it]

[Where do you think such high image quality and battery life come from?] 】

[Indeed, you can still fly at almost 6,000 meters, it's all money]

[To be honest, technology is quite developed now, as long as you have money to add materials, black technology drones can be made for you]

Bi Fang patted Jarrett on the shoulder and smiled: "It's okay, it's the greatest luck that people are okay, if you really want to pay for it, I'll come out when the time comes." ”

Press a few buttons and the detector reacts instantly.

Bi Fang cautiously walked a few steps, 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 was excited: "Hurry, hurry, dig up!" ”

The three of them immediately moved their hands.

"Damn, this snow is so hard." Yao Jun dug for a long time, and finally struggled to lift a large snow block.

Bi Fang also joined in, and after two or three hours of recovery, although the muscles were still a little sore, it no longer affected the activity: "No way, the avalanche snow itself may be relatively solid snow blocks, and when the avalanche fragments stop at the end, a large amount of kinetic energy will produce a compression process, resulting in a hard accumulation of snow." So a lot of teams will bring snow shovels, but it does take up space with things, you wait, I'm going to make a tool, do you bring more crampons? ”

"Brought it." Yao Jun took out crampons from his backpack and handed them to Bi Fang.

Digging snow by hand or on a snowboard is extremely inefficient or even impossible.

According to statistics, the average time to dig out a completely buried person using a snow shovel is about ten minutes.

If you dig by hand and on a snowboard without using a snow shovel, it will take about an hour to dig. So when trapped in a confined space is, so many people dig and dig for more than an hour.

However, in the case of digging holes, it is not easy to use a shovel, and it is better to dig by hand.

Bi Fang, who came to the side, pulled out the lifting rope in his backpack and cut it off, and then took out the spare crampons.

"The crampons have a jagged head that is sharp and hollow in the middle, and we wrap the middle part around it with a rope to use it, and finally attach it to the trekking poles, and a simple snow shovel is made."

Bi Fang wrapped the rope around the spare crampons, and at a third of the position, he wrapped it with the trekking poles, and at the same time wound back and forth in the gaps of the crampons, but the position of the heel of the crampons and the trekking poles formed an X-shaped solidity, so that they would not move left and right and easily disengage.

Soon a simple snow shovel was formed.

[Snow shovel or something, is it necessary?] Not necessary]

【Ready-to-make】

【Real DIY!】 】

【Excavation! 】

After concocting the second one, Bi Fang and the others excavated much faster.

When the signal was the strongest, Bi Fang stopped everyone's movements: "Okay, it's very close, be careful not to break the drone." ”

Jarrett was the most anxious, the first to throw away the shovel and start digging the hole, and soon, the black drone revealed its spiral wings.

"It's out, it's out!" Jarrett carefully took the drone out entirety.

"Let's see if it works."

The photographer who had been following the base camp saw the drone being dug up and immediately operated it, and soon, the snow-covered spiral wings spun rapidly, shook off everyone's body of snow, swayed and flew up, and gradually stabilized.

The audience, who had been in the first person, suddenly noticed that the perspective changed to a high-altitude top-down perspective.

【There is!】 Pregnant! 】

[It's still comfortable to watch in the third person]

[First-person stimulation is exciting, but it's usually a bit boring to watch]

The audience cheered and found Jarett's drone, and Bi Fang searched for it in a fake way, and successfully found his drone.

"I can finally see your barrage again, and the one-sided communication has always made me feel like no one is listening to me in class."

Let the drone take off, Bi Fang was finally able to stop camouflage, and quickly led everyone down the mountain to see if the detector had a signal.

But when he came to a crack in the ice, the detector did not respond, but Bi Fang made a discovery, and his nose fluttered slightly.

"Wait, it smells of blood."
