SRT Tree Climbing - SCAM 3:1 Mechanical Advantage Part 1of2 

Elegant is the word to describe such a delightfully simple solution. And simplicity is the hallmark of genius - but don't let that go to your head. Keep taking the p*ss out of yourself - that's the hallmark of modesty - hope you're not harbouring any secret ambitions to become a comedian! I'm trying this with my Hitchhiker 2. Can't clip back into the same carabiner with that, but so far using a rigging plate plus a second crab is looking good. Thank you so much for going to the trouble of sharing this with all of us. I'm only surprised that this hasn't gone viral in the Arb world.

Starting Climbing 19" , and watch the video in that year . But I getting to know the SRT System and Putting It to use at 2021 . Revisiting this video help me alot

just came across you for the first time, like how you're thinking, and love your captions, funny and real educational really petzel... send this guy a check haha

Hi, great video. I like the way you kept it simple. I noticed when you took the 3 to 1 rope off your main carabiner the gate didn't close and you started to take up Slack. You were holding it open with your hand. I'm sure closed when you release your hand. Be careful up there.

Thanks for the info I am 60 years old and just started tree climbing. I have climbed poles all my life. I like the freedom of the trees. I am not sure how many years I can keep it up. I use all the tricks and tools I can to make it easy. I would love to get my hands on an Akimbo. Right now I use the Petzel zigzag.

Great stuff - for those who'd like a ready reference to the content, here's my take 1:22 Genesis of the SCAM born out of a preference for 3:1 mechanical advantage system for limb walking, one that has minimal gear and is self tending 2:26 and won't get lost (dropped) and it readily retrievable (theory 2:45🤔) (demo 7:20👌). 1:56 SCAM - stands for Single Carabiner Access Method 2:26 Self-tending. 2:45 Retrievable hardware 3:14 Set up: Short and simpler version of the SCAM 4:11 Issue: Side loading climbing device when pulling above the device 4:21 Solution: Adjustable rope bridge to give yourself slack so you can pull below the climbing device 5:16 Carabiner requirements; needs to be locking and life supporting >23kn. Design: broader on top, narrow bottom. Note 5:48 DMM Revolver doesn't work with the SCAM. 6:25 Ultimate carabiner for the SCAM is the Petzl RollClip Z 7:06 Set up: with a Petzl RollClip Z 7:20 Another beautiful thing about the single carabiner: Readily dismantled and retrievable carabiner (its come home to daddy) 7:47 Climbing line set up: 8:19 Aid to making footascender tend like a dream👏😇: Simply girth hitch a throwbag to the climbing line below your foot. Another Tom Dunlap innovation 9:02 Perfunctory Dad Joke about Burr Oaks 😁 9:27 SCAM Set up in the tree

I don't care if you talk a lot, this is entertaining!

I saw and learned this maybe a year ago or more. Ive used it a lot. It works great. Love it.

excellent, good vid. That knot looks like a munter hitch with an extra half wrap.

Great concept. As you were looping the upper carabiner I said (to myself) that's an HMS, a munter hitch with an extra turn. I've played with it a bit and using a Munter is even simpler and faster.

I find you pleasantly entertaining.

Thanks from sweden! Great!!! I do the Scam knot by turning the carabiner, just i bit faster.

Love it, been using Richards ring method when I had to work a tree SRT because I had no way of isolating a limb (I own no SRT gear at all), this is a lot simpler, but I will probably stick with the ring because I rarely need it, I always run out of biners though (Who doesn't?) Subscribed.

O MY GOODNESS both informative and funny , I would so volunteer to hold the camera for ya ! ( smiles ) honestly another great video .. Thanks Joe

Continue with the videos. Informative but also really fun to watch. So if you promise to send them out I promise to press like.

My favorite stationary, retrievable redirect method😎

Awesome video man thanks for the knowledge

Is there a way to set this up in the tree to make the climbing easy with the 3:1 advantage?

Hello sir, i’m a municipal firefighter in florida and a recent suscriber. I’ve preparing to take a rope rescue class soon, i discovered your channel while researching knots, systems, etc. I cannot overstate how cool your scam systrm is, i’ve been looking for something practical to incorporate into rope rescue with minimal gear and i think i found exactly what i was looking for. I plan to show this to as many firefighters as i can, seeing as we always have rope and caribiners lying around. Let me know if this is ok with you and if you have any thoughts on how to incorporate the scam system into rescue operations i’d be all ears. Thanks again for coming up with this.

Damn, was sure I'd found a solution to the single point of rope friction by using the dmm revolver rig twin, but after pulling the manual, no joy. The double sheave option is limited to small diameter ropes (5-8) and the pin must be installed for the double. Loving this concept, btw. Thanks!

Neat trick. The only issue I can see is that you have to lanyard in and completely unload your main climbing line, but there are ways around that. I like the simplicity and the easy retrieval, with the carabiner sliding back down. 👍

Cool. It works well. Caveat: tie a knot about 5 feet from BOTH ends of your rope. It uses a lot more rope than you think. The end with the knot may not be the one that runs out. Don't ask me how I know.

Everybody needs to be careful of this guy, he is a literal "scam" artist. lol I bought the z pulley, and can't wait to use the SCAM technique. Thanks for your very informative, insightful, and clever videos, as well as introducing me to Richard Mumford and his SAKA. Gonna become a supporter of him, not the jockstrap kind either.

Wanted to say thank you for this video, am re-watching it as I intend to mess around with it while working later today, at any rate I've gotta double-check as I don't think my comment actually submitted yesterday to your video on Mumford/Weaver, if not then I'll be re-submitting a gentler handling of it but if it did I wanted to clarify that I think you're a good guy (when you put up those text-over-video comments of "i talk too much" or 'duck face' I found them totally unnecessary/mildly self-debasing, your videos are *awesome* and you've got *nothing* to qualify/note like that, if anyone's got a problem they can try and find someone else who explains things as clearly as you do!) At any rate, while I'll be including this in my comment (or updating my comment) on the Weaver/Mumford video(s), I found something this morning that just makes my point in the most hilarious way possible- in the same way that, no, neither Weaver/Michael/Mumford should be able to "own" the knee ascender since it was in common-usage (black&white beranek photos should be all the patent office needs to say NO to anyone's claims on the thing, and no I don't think subtle changes to fabric-types or the manner the elastic runs the tether are novel enough to warrant anything), THIS GUY has literally had some company make him eye&eye split-tails that he calls "The VT Prusik"(TM!), ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Z-xjqI1WOY8.html , it is hilarious the guy does a video on split-tails but is acting as-if he's got something novel in his hands, just a perfect illustration of how nonsensical Weaver's/Mike's/Richard's claims at "patentability" of their versions of knee ascenders truly are!! Thanks for all you've done, your practical videos like this have been useful to me in the past but your summation of the Mumford/Weaver(&Mike!) issue is just fantastic, found it on the Reddit /treeclimbing thread (which had me pretty pissed-off as it was an open-letter from Richard about whether he should press-on or not, and it was 1.5wks old w/ like 3 replies on it!!!) Can't wait for someone to try and patent SRT as a method/technique, if you can patent anythign that's not claimed yet then why not? Then you license it to any&every climber and company that uses SRT and just bathe in your royalties (am I doing this right? ;) )

Have a couple questions or thoughts, you decide. Wouldn't using a micro pulley at the device carabiner in the system increase the MA? Also what type of rope grab are you using on your adjustable bridge? oh and where did you get it?

Great idea! Looking forward to trying this.... Enjoyed info, filming and even your humor... ;)

Ok..... I received my Petzl Z Pulley yesterday! I looooove having this new redirect idea of yours in my mental tool bag. I have been using a large ring with an attached accessory carabiner for branch walks and redirects, but the SCAM System with the Z Pulley is so efficient and smooth. Thanks for sharing the system with us Free Fallin!!! Awesome..........Awesome........Awesome : )

Tree guys dont use screw gate for life support. Its widely accepted on other areas but not in tree work

incredible video. this is elegant. such a simplified way of doing things.thank you sir

Looking at this knot I would say it is just a munter with an extra wrap. Wondering if it would be safer to pull the final bite through the carabiner in between the knot and the spline side of the carabiner (instead of the gate side). I have not climbed with this 3:1/redirect, so I'm not sure if it would be an issue. Might be a concern if it is unintentionally loaded when set up as a redirect against a branch or spar. Great idea. Look forward to trying it out and seeing more from you in the future. Subscribe.

If it ain't burr oak! Priceless!

Will this work with a hitch climber instead of a mechanical? I guess I will find out, it’s just so cold out that I’ll wait till another day. :)

Are you always entertaining, amusing and clever? Just trying to figure out if you're gonna disappoint me eventually. Yes, my approval is more important than the line you climb on

Lolz to your monologue. Thanks for video

SherrillStuff sticker was a nice jab.

This guy does talk a lot - and subtitle a lot … it's all good -- nice presentation!

Oh, nice video

Hello. I've tried your technique a couple times now. I'm finding that the carabiner that is tied above to offer the 3:1 mechanical advantage slips. Have you experienced this? Any tricks to keeping it in place? Thank you.

I assume it's better to use a pear carabiner on your bridge to allow space for the bight?

Nice and simple thanks

The petzl rollclip z is a 20kn carabiner or am i wrong?

just blew my mind!! will it work with a ropewrench?

I love the SCAM system, have been using it since I saw it here. There's a big BUT if you're usingthe Petzl roll-clip Z: it's rated at 20 kN, not the required 23 kN

"Actual climbing speed".......bloody brilliant . Belly laugh

Love it! I've tried a few times and my only concern is that there is rope on rope friction at one point. Seems fine is you go short distances or go slowly when going long distances. Not something I would want to use over and over on the same section of rope. Curious if you've come up with any solutions to minimize that? I've been trying to think of a clip or cover you can put on the rope where it rubs.

Could also twist the carabiner instead of wrapping the rope? One and a half twists will give you the same as one and a half wraps?

Where about are you in Wi? I am in Menomonie, West central. I started climbing trees as a hobby too, now I am trimming them as well, at least my own. I am looking to climb with others and would like to learn from you and climb if you aren’t too far. PM me if interested.

Sorry but I don’t understand what it is used for ?

Joel, can I only use this with an adjustable bridge? The knot looks like a Munter once you load it. I like it. Oh, and by the way, we could all use more tail...

Lovely equipment but most you want to show is missing because didn't catch by camera. I cant see important moments which is anoing. Didn't learn much

Slick!

dude don't drop things lol! cool idea and good video but i feel like it could slip down the carabiner and get you stuck in the tree

I'm not falling for it. SCAM!

NEAT

I tried it today with a rope wrench and hitch + pully. I could not descend : too much friction....any solutions , suggestions to make it work ?

how come you sound more theoretical...? And how is all you gear looks like its all new.....you would think there would be wear n tear on your gear....

YA.....no! I'm very interested in what you are trying to show me but the camera footage is too complicated to understand. So maybe you could do something a little different on the same thing. Lighting and angles are all wrong. No disrespect intended, as I said, you fix it and I'd watch again. Nice try though. At least your out there doing it for us. Thanks.

Where do you purchase a bulldog?

love the scam. thanks for sharing

Wanna be besties? 🤭

i only give a thumbs down because while in the oak, your camera is in a terrible place for showing what you are doing. yes this is going to take me some practice but i wish your video showed me what was going on in the tree a litter better than what you were able to provide.
