Is that a Mazda 323 in the background or a Civic?
1991 Civic...good eye
👍😊
1:42 This is not how to ever hold a crossbow. This is how to chop your fingers off. If that line shoots, it will cut your fingers clean off.
Why doesn't the climber have a belay device on??
She's climbing on a full circle rig, and so can be lowered. It's a strategy for new climbers to climb high into the tree on their first day without having to also learn how to descend. ALso handy for rescue...
Thank you!!!
Lol watching the video and I’m like, why not just buy a rope with an eye at the end. Then I saw the year this video was created. Lol thank you for your tip
wasn't expecting to be hit with the asmr
What mm cord was the blakes hitch? Thanks and great video
it's been so long, i forgot...but it was pretty thin.
The orange is 1/2inch (12.7mm), the blue is 5/16inch (8mm).
girth hitch to your bag saves a bunch of time
Hands should not go over the climbing hitch when foot locking.
I've often heard that said, but it depends really on the relative diameter of the cord and rope involved. Some (like this one) bite very hard, and you can't knock it down, even if you tried...
I now understand why is called the Texas kick!LOL
Monkey fist work too??
Not really...coil tossing is best for short rope throws, and for longer distances the compact heavy throw bag and light throw line is best. Monkey's fist just isn't very heavy relative to the rope.
Placing your thumb in harms way while loading is not acceptable, you might want to share that with the other professionals.
Indeed...I thought we edited that, but apparently not!
Which knot is the one that you slide up as you climb and pull down on to descend? Brand new to climbing, and always have it set up by an experienced climber but don't know what that one is called
The one in this video is called a Blake's Hitch. There are numerous other hitches that are used to climb in moving rope systems, but this one is reliable, if a bit old-school.
Is that an Outward Bound compass rose on your helmet?
The best way is get yourself a monkey,train it to take the rope up the tree.They say some can do the entire rigging,I think i saw one the other day cutting trees.They getting better.
Bull.just throw the dam thing ,pluck it.
I've always seen the blakes hitch done in the opposite direction.
Hmmm...I'm not sure what you mean by opposite direction. It can certainly be tied left handed or right handed, but the mirror image would operate in the same way.
Why a "non-locking carabiner" for the autoblock?
A locking carabiner isn't really necessary here. It is common practice to use a non locking carabiner. There certainly wouldn't be any problem using a locking one either. These days we no longer use tube style descent devices. We have switched over to the grigri or ID for most purposes.
@@CornellTreeClimbing thank you for replying! I was concerned there was a safety risk to using a locking one that I wasn't understanding. This would work on a figure 8 setup too from what I can tell. I'm looking for a low weight backup in case something happens to my mechanical device.
@@the.mr.beacher A tube style device is a very solid backup and very lightweight. The only tricky thing with the figure 8 is that it requires a bit more space to install, just because it is a longer device. One could also use a munter hitch on a locking carabiner to descend, though the change over is awkward.
I found this to have great basics for me, plus a few great tricks I hadn't ever thought of before. Thanks a lot!
Please include links to any gear used. It would be helpful to me and you can make commissions on it too!!
thanks for this video, i learned something from this.
No
I always have been wondering of a creation of a crossbow fishline combo, I am very glad to see this idea come to fruition. But how hard is it to get the line where you want it? And how often does it get stuck in such dense forest?
The accuracy is quite good. We typically don't take more than a couple shots at branches on the order of 150 to 200 feet up. The arrow does sometimes get stuck, but because we are using fishing line we can pull hard enough to break the line. More often than not, the arrow just falls to the ground and we reel in the line. Over years of using this system we have only lost a handful of arrows. We even found one in a subsequent year that we lost in a previous one!
Ty very informative
Are there any foot devices just like the arm design so than when the foot going up the devices also going up as well?
How far can a weighted rope be thrown?
i like the ascending with a motor
This is a very thoughtful experiment. Coming from the climbing community, we would never climb on a prusik like the Blake's knot, it is strictly for ascending, but arborists do it all the time. They trade off a weak point in the system to make their lines more easily and quickly adjustable. The whole point is to limit any fall to only a foot or so, but if climbing above the last point of attachment, distance is doubled. This is worth thinking about when scrambling about the canopy, since it wouldn't take much of a fall to duplicate what is shown here. Heavy rope is worthless if the weakness is in the prusik line.That said, I believe most guys use heavier line for the Blake's hitch, and sometimes double up a variant prusik knot onto either side of a pulley.
You forgot to lock your rope into your jumar with those carabiners you saved which is vital in a how to video
A carabiner in the top hole of the ascender not necessary in this context. The only time I consider doing that is in the case when I have a rope under tension and/or at a crazy angle, as in following or cleaning a traverse in, say, a rock climbing situation. In recreational tree climbing you just don't encounter that problematic loading. Even so, it is really hard to accidentally get an Ultracender off the rope, and if you do, you have another back it up.
This is the way I learned to do amateur aid climbing decades ago. I notice that now many professional arborists have transitioned to a single 'rope walking' technique, because most of the work is done by both lower limbs and it causes less strain on the back because they stand vertically while ascending. There is some additional investment in gear, and they still seem to use a dual technique when moving through the canopy after getting up. In a 300 foot tree, anything that reduces work to get up there must be worth considering....
Oh, yeah...I definitely use a rope walker system. Some of the younger instructors have energy to burn, so they can still Texas Kick their way up!
The best rope ascencion way !!! . Congratulatios !!! .
What a load of tossers
I'd hire her
Luv the bag retrieve on a tug of the line
Please support my youtube channel and I support back
thank you for the video, Cornell... for me, as an enthusiast in tree climbing, seem a comprehensive video...
No pony tail no job - pity I'm as bald as a coot
11 year old video but it has been extremely useful for me in 2020 and the first video that showed me how to descend. There are countless videos about ascending techniques, but I suppose those folk assume descending is common sense. It wasn't for me as I had been thinking climbers actually descend using their hitches or ascending devices. I also like that in the video you have repurposed jumar style hand ascenders and have exploited wallet friendly webbing. Webbing is so cheap it is practically free but often stronger than the best ropes so it's strange it's not used more often!
" this is how your student looks when they get it over the branch the first time" lmao. Yea after a few thousand tries lmao
What kind of line and arrow how to put line on bow
Berkeley Fireline 20lb test and a bowfishing fiberglass blank
You can also tie two Blake’s hitch’s one above the other and cut out the upward hip thrusting
anyone else preppers?
Use some fishing line a tennis with a little sand in it to get the other rope to tide the branch that needs to come down.
Nice video Best of luck Greate job Thanks
Thanks
Are y’all reset/redressing the Blake’s after each drop?
Good question...I don't recall. It was so long ago...
Yes you did it was noted at the end of video
As a tower dog, I always wish I could use this technique.
Okay that last tip was invaluable.
*Very light but sturdy ascender that anyone can afford✏️>**allmy.tips/ClimbingAscender?X** I hung a foot loop through the large bottom hole of mine to get a leg up and save energy. I'm using it with 12mm rope and don't have any issues at all with it slipping or damaging rope. Don't trust it as your primary life support, but I definitely keep mine on the line as a handhold in case things go south. I wish this company would make a copy of the two-handed petzl butterfly-shaped ascender!*
GOOOOOOOOOOOOOOD
