He shouldn't be grabbing the top of the linescale, that can throw off the measurement a lot!

Just doing my part to up engagement: I'm pretty ambivalent about units but I'm a HUGE fan of decimal points. I'm so mad that you didn't go with the KN measure.

Love these courses, quickly becoming the SOP manual for a generation of rope sports enthusiasts and athletes.

Any chance you could re-do this test without pulling from above the meter to get some/any sense of the actual comparisons? Thanks for the great content!

As an American I don’t understand pounds. All the climbing literature I’ve read is in newtons, the companies list the strength in newtons and it’s easier to understand as long you didn’t go to high school in the 50’s. I realize this doesn’t matter though. The videos are super entertaining and almost more so because I’ve never gone canyoning. It’s like a whole new world.

100 lbs = 45,4 kg 200 lbs = 90,7 kg 220 lbs = 99,8 kg 250 lbs = 113,3 kg 300 lbs = 136,1 kg 400 lbs = 181,4 kg 500 lbs = 226,8 kg 600 lbs = 272,2 kg Freedom units my ass, onscreen pop-ups? Nevertheless, awesome and informative video series!

But why not use N instead of kN lol On the serious side the hand on the carabiner attacked to the top of the measuring device is probably adding a significant amount of noise to the measurements. Would you be able to avoid that next time?

I must respectfully add in , Wet rope option . stainless steel devices , larger diameter rappel lines ( ex; Bluewater assault line ) . Thanks for the pounds reference as many of Us readily understand it . Great video as always !

Phenomenal work. As you keep mentioning, you lack the experience to choose which setup you would use when. That gave me two ideas for videos. Idea 1: have Brent pick a route and give us a rundown of what he actually takes with him. Let him talk for a while about why he would choose each system or piece of gear to take. I would love to just hear his thought process in that evaluation step before the actual outing. Idea 2: once you’ve planned it, film yourselves going down a canyon and test Ryan the entire way. Make him look at the terrain and choose which system to employ with Brent there to grade his choices. It would be a cool follow up for the first video. Love the content, keep it coming.

"We dont wanna deal with 0.5, 0.6 kN" then just use Newtons, thats the entire point why the metric system is so much better...

I didn't knew I needed this, this is past what I expected to learn from this series, I LOVE IT

Hey, may have missed the video, but have you done a test on some of these techniques with wet ropes? I'm a pretty experienced canyoner and I've found systems like these to be variable under wet rope conditions. Usually only the first rap will be on dry rope, and then everything else is wet. Some systems gain friction on wet rope, and some lose friction. It's weird and interesting and you guys should investigate it. Obviously this is a can of worms and has all the usual dependencies of rope-type, rope diameter, rope condition, device condition etc., but I figure if you're doing the tests, then what better opportunity to investigate these edge cases? EDIT: My hypothesis (which is probably wrong) is that friction on wet ropes is lower on a straight path such as a rack or a whale-tail, but higher when it bends through devices such as eights.

What's the silver device hanging on the wall at the end (16:09 onwards) with the similar design to the CRITR/Palikoa but two tracks?

Next time use bigMacs of force, instead of pounds. They are basically the same weight, and it is the real freedom units

IMO, and it would be hard to test, but the real check of rappel gear would be to standardize on a rope and a weight, then measure acceleration and terminal velocity over, say, 50 feet with the brake strand only under its own weight. Might be interesting to see which devices and rigging methods would actually keep a 185 pound climber safe if they completely lost control of the brake strand. Obviously the auto-braking ones would win out, but among passive or mostly passive devices, there could be some surprising results.

Had to at least get a sticker and represent while I'm out in the wild! Love the channel and everything y'all put out!

i use a totem and put a biner through the stitch plate and the large o spot and it does not move at all under tension and is easy to remove to lower

You should do an ascender break test. Maybe test the $30 amazon ascenders

Can I enter to win a wall like that?

The biggest variable that's unaccounted for is the tension on the signal line

Nice! Did you guys end up break testing a Crittr as well?

Love it!

I know it's not relevant to these courses, however does anyone know the best place online to purchase 3/4 inch amsteal.

When testing friction devices can you take a temp of heat generated? My camera has an IR temp camera so shouldn't be to expensive to get one. Love your tubes. Answering questions with facts instead of just " that's what the book said" or my old time hate " that's how we've always done it ".

what's the diameter of the rope? i use the joker a lot and i,ve never experienced any slippage, i usually use the petzl club.

What is the name of the device you're holding at 0:45 or the ornge one next too it at 4:00 i used to use some similar to the orange one that supposedly was discontinued like 8 years ago as an OSHA violation for tower work but we used them for tower painting because we trusted it more when we locked them up with friction binds so if someone dropped a bucket of paint into our gear. That way if it failed hopefully it would just slide/fail until it reached fresh rope vs. seeing auto belayers sometimes fail all together or over time as paint accumulated inside them. I really really want to add one too my current kit. I recall them calling ours a double fisks, but all i can ever find are pictures of what we had, never anything for sale. Apparently OSHA banned them? But we ignored that ban because what we were doing was so specialized vs other tower climbers.

I would be interested in comparing such devices with thinner ropes. What is the thinnest ropes used in canyons? Do you have 4mm, 6mm, 8mm dyneema ropes to place through some of the higher friction devices like the Pivot?

🤦‍♂️🤦‍♂️ pulling the rope above the line scale 🤦‍♂️🤦‍♂️

Just to be that guy (and I know any kind of engagement helps you) but if kN (kiloNewton) too big is why not use N (Newton)? It was all about FREEDOM wasn't it? And yes, I really enjoy all your videos and only comment regarding reeeeeeeeeeeeeeeeeeeeeeeeeeally unimportant stuff.

Are you grabbing the rope ABOVE the device? 6:07 and other times..

@01:17, damn. what a heart break.... how are we supposed to have a revolution if you keep switching back and forth?

this is the 5th time I have watched this video ( or so), why is Ryan wearing a puffy and Brent a T shirt? things that make you go Hmmmm.... love the channel! just an observation

1:14 Amen for Freedom Units. ‘Tis confirmed. I now officially love this channel. Please continue to sell my rope products in communist measurements though.

I really don't get the complaints about not using Newtons as the measurement... As if converting the weight of a tasty convenient snack food measured in ounces to pounds would simplify things, let alone change the results... 🤷‍♂️ Not to mention strawberry or original?! Not one of these commenters has even specified which flavor of Newton to use! Absolutely ridiculous! 😠

There is always the option to just use newtons, without the kilo prefix.

Just to be facetious: why are you using pounds?

Hum... If you don't want to use kiloNewtons, you know you can always use, you know... Newtons?

Would you prefer people donate directly through PayPal or patreon or would you rather people buy gear off the site? Because for example personally I wouldn't be able to do both but I'd be willing to buy a carabiner or donate a couple of bucks but I wouldn't be able to do both. Thank you
