so imagine that i am playing with the

tube style device.
The higher my brake

hand goes, the lower mechanical advantage

it gives.
So here is the question, if i

would have my brake hand right here, and

my climber would take a fall at this

moment, will i have enough reaction to

bring my hand down or my hand will

simply just get sucked into the device?

and maybe i will get hurt and let go

this hand and

sad story. Ready, so to make this

experiment a little bit safer, I started

with my break hand a little bit above

the belaying device go

whoa

ow

i got my hand pinched in the device

[Music]

probably somebody's already typing in

the comments, "oh you should never

keep your hand here". 
Good if you have

that feeling, then my job so far is going

well so let's continue.
- Ready?

yep

well now I had like a reaction to go

down because I was scared

I was anticipating it and I went like

The main reason for this demonstration

is that I see mistakes both in beginners

and advanced climbers.
Beginners,

sometimes do this, where they take the

slack

very slowly as the climber is moving and

then they lower the hand and do their

favorite transition, and then they take

the slack slowly again and rise the hand

way too high

don't do this!

go!

whoa

yeah now I kind of learned the instinct

I guess it boils down to how quick you

are exactly my first was probably the

most realistic where I was not like

quick as

what's the quick animal? you know a quick

animal?

cheetah
- yeah so if i don't have a

reflexes of cheetah, the hand just goes

into the blank device. m
Maybe also the

glove provides better grip on the rope

okay

that's

for you

if Ii get hurt,

please send me some donations! 
so now I'm

gonna hold it really up, man this is

scary! 
While experienced belayers

sometimes do this.
If they see the

climber falling and they decide that

they want to take some of the slack out

and they do this quickly. If they would

miss time and their hand would go up in

the moment where the climber would load

the rope they might not have enough time

to bring the hand down and the reason

why i'm saying this,

because

i know a person who was dropped down

with this device.
It's a click up it's

assisted device

meaning it locks

however,

if you have your brake hand up here

it doesn't lock. The person who I met

told me a story how his belayer tried to

take out the slack really quickly during

the fall but he fell all the way to the

ground. So i'm gonna talk about belaying

devices later but you must know that

even some of assisted belaying devices

do not protect from this. Man this is

scary

don't do this ever
Venga! (spanish for go!)

[Music]

[Music]

just because I know that he's about to

fall and i'm kind of

ready to lower my hand so I'm not saying

that taking out the slack during the

fall is a big no, i'm just telling you

what are the risks and if you want to do

this be a cheetah, and if you're not a

cheetah maybe use assisted belaying

device which doesn't have this risk

let's do one more

i'm getting known already for being a

bit crazy

so one more of what not to do

go

man this is scary
- yeah

so

it ended up here and I was holding here

so it's not that much slippage

but again just because I know also

probably somebody is gonna comment that

your hand shouldn't ever go up it should

go forward and down

but I guess if you're trying to take a

slack really quickly doing forward and

down

might be not as quick and comfortable as

something like this

so in the end my goal is not to tell you

what to do just to demonstrate what are

the potential risks if you are not the

cheetah or you are not aware that these

things can happen like in the story with

more life-saving tips here and here is a

very in-depth course on climbing

equipment and safe belaying and if you have

seen all of it already good news I'm

already working on new episodes for it

oh and this episode is brought to you by

you, people who are supporting my channel

by visiting my website and knowing how

to do that thank you enjoy climbing
