The great thing about the vt is that if you are using it to ascend it will loosen up as puessure is applied to the opposite end when used in conjunction with a small pully. I was an arborist before I started climbing rocks and this was the preferred way to climb up if you are using a doubled rope system, before all the fancy single rope techniques came about.
i think that the blocking knot must be under the belay device, on the active rope. If you don't do that your knot could block so high that you can't free it. That will leave you hanging on the rope, and you will only have the option of climb up the rope to release the tension. En mi opinion el nudo de bloqueo siempre debe hacerse por debajo del dispositivo descensor, sobre la cuerda activa. En caso de no hacerlo el nudo puede bloquearse en la parte superior, de tal manera que sea imposible liberarlo. Esto te dejaría colgando de la cuerda con la única opción de ascender por la misma para liberar la tensión del nudo.
This is true when using a prusik, but, if the VT is correctly setup you will not have the issue. We shared your concerns years ago before we got the VT. Thank you for your comment we hope you give the VT a try... it's really interesting and well worth a few minutes to experiment in a safe environment.
it can, so it's something you need to be aware of and don't make the extension too long. In the same way if you put abseil device high and your prussic loop is too long it will hit the abseil deivce and not lock, you need to understand your kit and set up. This way is at least very easy to ascend the rope
I have tried this setup, using an arborist eye to eye. michoacan friction hitch and my belay device under the hitch. Worked alright. UNTIL I came to abrupt stop. A situation I would find myself in regularly, cleaning a route or arriving at anchors, The friction hitch completely locked up on my rope. 100% could not continue lowering on it. Maybe my rope was too squishy. Or it was that I tested this with a climbing single rope, but I DO NOT recommend; hitch above rap device. Took my ascender and a bunch of hassle to get out of the situation
That's why specifically you use the VT hitch.. it releases better than most hitches.. and prusik descenders are not made for high speed descent. Rope prusiks are made for slow controlled work. Not recreational play. And VT is not a particular rope, but just a hitch. Tachyon is probably the rope..
If the prussik is above the belay device, then the prussik has to hold your whole weight in a fall. If it's below the device, then it only has to act as a brake hand, and as we all know, that requires significantly less force.
and??? We all know it is faster abseiling with a prusik above than below too. Are you worried it will break? There is also the advantage in that if you did fail to tie back up knots and the rope slipped through your plate you at least have a chance of it grabbing before you disappear.
No, this is the BlueWater VT tied in a VT. It's widely used in the arborst community as a single ascending send system. Remember this is just a backup., your hand is the most powerful backup
I’ve been reading about this device/technique. Seems like it uses a lot of rope above the climber and at some anchors it might be hard to fit it all in and still test the rappel while still tethered.
Very helpful! I've been learning more rock climbing and rappelling info for emergencies (I live in the mountains, kind of essential) and this is by far the best set up I've seen for rappelling. Clear and easy to understand in your video, thanks for posting!
Thank you very much for that simple tutorial. I'm a beginner so I'm doing my research. I like the idea of the back up with the Prussik along with the ATC Black Diamond Reverso. I'm just thinking of basic rapelling. Nothing big.
Ideally you should probably have the back up under the rappel device to hold the rope in brake position if you go hands free for any reason. The VT prussik is neat, but it isn’t a true prussik-it’s a different friction hitch entirely, and it seems sketchier as it doesn’t hold the rope in brake position...
Thank you for the comment. We thought the same at first but found that the BlueWater YT provides plenty of security for backing up a rappel. In the end it's all up to personal preference.
Recently I notice a lot of climbers like to tie the prussic below the device (attached to their leg loop) to grab the brake end of the rope, (it's not an ideal method, it's just another method) I learned both methods back in 2001 and I've always tied my prussic above the device, because of this I revisited the idea of tying the prussic on the "brake" end of the device (just today actually) and I was reminded of the clear advantages of tying it above the device and it reminded me why I do it that way... try it out ;)
you can also extend the belay device (sling, etc) and clip the prusik in your normal belay loop. Much safer position than leg loop. Although the leg loop is possible but not recommended as the prusik can jam the device if you lift your leg too high. I've seen the "prusik above device" only twice, one time in this video and couldn't imagine opening a normal prusik knot under tension. This way it makes much more sense. Still would prefer the brake hand option :)
There is no reason to extend the system with a VT, that is one of the good points of the device. By extending, you increase the chance of getting hair stuck in the system and not being able to reach the VT. Extending the system was only needed for when there wasn't a rappel safety that could work above the rappel device and be releaseable.
Generally that's correct, but the VT Prusik by Blue Water is designed so that it flattens out when under tension which provides a better grip. Thanks for being a part of the Live Rogue community.
As an arborist, I use a 11.5mm tachyon climbing line, and for the valdotain tress prusik, I use a 9mm epicord prusik knot. 30" eye to eye prusik cord. Your prusik cord should indeed be at best 80%the diameter of your climb line. Knots that use same size line are the Blake's hitch or the tautline hitch. Word of caution, we call the tautline hitch the "sui-slide". I don't recommend that knot.
@@DavidLDFL Check out the climbing arborist RUclips page or educated climber. Very good pages to learn some things about rope work or climbing in general. I can translate most things from tree climbing to rock, but there some things from rock climbing that can't transfer back to arboriculture
Can this exact same process be used with two sides of the rope going through the ATC (both ends on the ground) rather than just one as shown in the video?
Dakota, a few questions: 1. Is it possible to simply clip the VT sewn eyes through the ATC Guide mode aperture? To me, that would simplify the setup and remove the awkward runner. Rich Carlson appears to do something similar with the Totem. 2. Would this VT hitch work as well with double strand rappel? 3. Is there a convenient way to attenuate the VT prusik cord for (say) female climbers with shorter reach?
A1: In theory it seems like like a workable option. The ATC Guide mode aperture is clearly rated for the forces that would be applied in the rappelling scenario. My only potential concern would be the added friction to the belay device caused by the leveraging motion which would occur with the VT attached in that fashion. My gut tells me the leveraging effect would not be significant enough to hinder the natural motion or movement of line through the rappel device. We will test the idea and show our results in future videos and/or you could experiment with it in a controlled environment…. Let us know what you learn. As Rich Carlson discusses in his video you should place your VT lanyard if you plan to pass a knot. ruclips.net/video/Z-xjqI1WOY8/видео.html A2. Yes, the VT Prussia works well with a double strand rappel. A3. The easiest ways I can think to attenuate the VT prusik for those with a shorter reach is to use an attachment point closer to the climber - even use the harness belay loop as an attachment point if necessary.
After some research it is a very dangerous set-up. If the VT is loaded it's only connection to you is the ATC cable which is not rated nor designed for any load. Loading the ATC in this manner could be deadly.
Live Rogue That was a ‘eureka’ moment for me! My initial thoughts were, sure, that’d be a nice clean setup... but alas, of course its then only through the cable since we assume you’ve lost control of the rope. Seems so obvious now :)
@@LiveRogue I know this is like 5 years old, but I think you can still go back and edit your original comment. Perhaps it would be wise to edit that original answer comment to clarify that it's NOT a workable option, just in case someone doesn't read past it that comment. Thanks for the video!
Hi, could you help me with the reason why ATC is used? From my amateur research, it seems like the VT can be used for rappelling by itself without any other devices
An ATC (or other belay/rappel device) handles the heat from the friction of sliding down a rope. When rappelling use a backup; a VT works well for this.
Sorry I'm so new to all this, so when I've tried this on horizontal practices it stops me when I don't wish to stop. Do I need to keep pulling the knot down as I descend? I have lessons soon but I wanna get ahead a little on the basics
Yes, you will to pull on the knot to allow it to let you down. This is the same as any other backup setup. The idea is if things get too wild and crazy and you completely let go of the rope you will not fall to your....
@@LiveRogue Hello, I would like to ask you something please!! Usually we are holding the knot with our ' strong' hand? I mean If you are right-handed with the right? Thanks in advance!
@@LiveRogue that was going to be my comment. I think it would be very helpful to show harness and tie-ins in your video frame. Otherwise, I really like this setup and will be testing it out.
I'm sure u have a significant amount of experience but, gate away when you clipped belay device appears to be a beginner mistake. Can you tell my why you chose to clip away from yourself and not towards?
Thank you for your comment. The ATC was clipped into a tether on a BD Alpine harness that does not have a belay loop which orients the carabine left to right. Since the set-up is near eye level and is connected with a locking carabine I feel very comfortable that the gates can be monitored and will not impact the strength or function of the rappelling system.
I wish people would quit calling a hitch a "knot", it is not a knot, it IS a hitch. The VT is a hitch of the asymmetrical prussic family. a loop of cord can be utilized many ways , one of them is you can create a hitch, otherwise a cord loop is not a "prussic" loop. language is important.
I used to be an arborist and this was the preferred prusik knot for a doubled rope system used in conjunction with a small pully. Works great trusted my life to it hundreds of times.

It’s a bad idea to put your Prussic above your repel device as it takes 100 percent of the weight. Therefore releasing it is tough if it’s placed on the brake end of the rope it’s just as safe and releasing it is far far eaiser
