I think probably it is more dangerous. Lots of instances where you might want to get out of a tree quick or with one hand. It's certainly not safer. It's just not required.
That makes sense, thank you!

if you have to move your rope around the tree whilst your climbing then all those knots may get stuck which isnt great.
also in the event of a wasp or bee attack you may not want to have to undo all the knots on the way down, unlikely i know.
Thats true!
so one stopper knot, grigri and prusik is safe enough in your opinion?

I don't understand why you need knots, unless you run out of rope? Up until a few years ago all tree climbers used to ascend and descend was a rope with some type of friction hitch. No backup or anything.
Is it more dangerous with knots?
I just make them to prevent a bigger free fall

Back in my rock climbing days (20+years ago) we were taught to back up the descender with a sling or even a shoe lace tied with a prusik knot, if you didn't and for some reason lost consciousness or dropped the rope you would end up descending freely. You could still rappel with one hand as you hold the prusik knot as you tend the rope. It took me a while to get my head around tree climbing where we just relied on rope on rope.
The knots every 3m sound like a complete waste of time, you could have one at the end of the rope if you really needed.
The op really should get some training as they seem to be making it much more complicated than it needs to be.
Hi, thanks!
time really isnt an issue because no one has to pay me 😁
So I dont mind making a knot every 3 meter.
also i’m climbing a static rope, so imagine i’m free falling 8meters or so and the knot on the end of the rope saves me. That would hurt really bad because of the rope being static, not dynamic, isnt it?

Here's a caveat: I don't use a grigri, I've never enjoyed them. They don't solve a problem I've ever had. But the theory is the same for any belay/rappel device.
You need your prusik on a loop that doesn't reach the bottom of the device. This can be achieved by clipping it to a leg loop instead of your belay loop, or by extending your device up a little by clipping it to a short sling, which is larks footed to your belay loop. In rock climbing, I would always do this with my cow's tail, or personal anchor, with a knot tied halfway down it, so the belay device is halfway along the sling. Like this, your device is far enough away from your prusik knot to not interact with it, but close enough to manipulate.
Now, this is where simple devices like figure-of-8s, atc, guide plate, reverso, whatever, are better than the gri gri: the hand that is milking the prusik on the downhill rope is also controlling the feed of rope into the device, leaving your other hand free to comb your hair or roll a spliff or sort out tangles in the rope, whatever you want. You don't have this luxury with the grigri, which needs a hand on it all the time you are descending.
Edit: Petzl do hundreds of useful infographics for using all of their products and the situations you'd use them in. Just Google image search "Petzl rappel prusik grigri" and "petzl rappel prusik reverso" and you'll get a good idea of what's going on.
Thank you for your time!
really informative

That sounds like a hell of a lot of faff. I assume you've got one hand on the grigri and one on the lower rope? Have your prusik on a shorter loop, below the device, and milk it at the same time as you descend with your downhill hand.
Is there an instruction video of this specific technique?
with the prusik underneath the grigri, and the grigri slips, isnt it going to take the prusik with it on its way down?
thanks for replying! -

Providing the prusik is dress and set correctly and you are using the approximate cord size then yes it should hold
Oke, thank you!

GriGri’s are very common in the rock climbing and mountaineering community. I have never heard of anyone feeling the need to back one up, and I’ve never heard of one failing under normal conditions, ie single person load. Belayers catch huge falls with them. I wouldn’t back one up unless there were extra factors to consider, such as a narcoleptic or epileptic user
Hi, thanks for your answer!
I really believe the grigri is save enough, but in my opinion the prusik knot/rope is a simple extra safety to add.
I also make knots underneath me every 3 or so meters just in case. Is that a good idea since i’m using a static rope? -
Thats possible but not really comfortable since I need both hands to descent with the grigri.
but do you think the prusik will hold?
thanks for replying btw!

Because of the length of the prusik rope

Hi all,
first of all, I do tree climbing just for fun.
I use my grigri to descend and also a prusik knot as an extra safety.
So I descend 1 meter, stop, take the prusik knot with me, descent another meter, stop…. And so on…
it takes way more time, I know, but thats ok for me!
is it safe?
will the prusik safe my life in case the grigri slips/fails?
greetings

Hi all,
is it ok to pack and store my static 10.5 climbing rope shown in te picture?
(I store it on a dark and dry place in a sport bag)
