    If you were to purchase a saddle to introduce people to climbing, which one would it be?

    I'm not sure if they are available in the US, but in Europe a Treeup TH 030 is a great choice. I've got one, and it's a perfectly fine saddle for a very good price. I'd say about as comfortable as a Sequoia.

    Minimalist rope walking setups?

    I've not been very active here lately so I only skimmed over this thread, I'd take the following system if I was to try ultralighting my climbing setup (currently going more in the opposite direction though :P ): - RopeWrench, about 200g, requires a rope 10mm or over - 8mm hitchcord with sewn...

    Need new phone battery case

    Apple offers some basic battery health information in the device settings, it should be under battery. This is not 100% reliable, but the only thing you can do quickly. But like I said, if the battery is older than about 3 years it probably needs to be replaced.

    Need new phone battery case

    Iphone batteries (well, phone batteries in general) usually tend to degrade to <50% capacity after 2-3 years. Chances are an Iphone 7 would need a replacement battery at this point, and that's a fairly easy and cheap thing to do. I wouldn't recommend a battery case. Those usually charge your...

    What do you use for a base anchor?

    I like my steel carabiners because they are easy to use, quicklinks also probably need to be torqued down with a wrench to get the same strength. Hey, I'm doing good. I haven't really decided what to do after school, I'm probably going to university though, something with physics/engineering. I...

    What do you use for a base anchor?

    I usually just do 1 wrap with an alpine on the end, I then secure that with a very beefy steel carabiner. That has always worked for me, but on small slippery trees I sometimes girth hitch a long webbing loop to the base of the tree and clip my climbing line to that, this doesn't slide up the...

    Minimalist climbing

    The usual ultralight climbing setup is some kind of RADS with the 2 components as light as possible. GriGri/ropeman seems like the ideal combination here. For a rope I'd go with 40ft of 9mm. Throwline and throwweight are probably optional at these heights. An Akimbo coupled with a single foot...

    New Look!

    I like it! Small complaint: the scrolling arrows on mobile block a large amount of the site. edit: must've been a bug, they are much smaller now.

    Rock climbing harness in the tree?

    A rock climbing harness is not comfortable while you are hanging in it, and it doesn't offer the flexibility that a tree climbing harness has. Still, it's perfectly fine to use one in a tree, I started out using a cheap and uncomfortable one.

    Covid Close To You

    My neighbours have it. They seem to be doing okay though, they're young so they should make it through it. This really isn't a joke though, and we aren't really prepared for this in any way either.

    rope stretch when falling on MRS vs. SRS

    My thoughts on this: If the ratio between load and stretch is linear and the system is perfectly frictionless the stretch should be the same; the rope has half the load, so it stretches half the amount, but at the same time the rope is double the length, which means it stretches double the...

    Cambium saver installation

    You can only have lower branches as a backup if you are using a base tie. I dont like the idea of capturing multiple branches in my canopy TIP, it should theoretically work, but it seems sketchy and unnecessary to me.

    Cambium saver installation

    The Friction on a branch is very small in SRT. You wont damage the branch by not using a friction saver. To damage the tree as little as possible, use a canopy TIP. You'll have the same issue as with the friction saver though: the rope will get cinched around the lowest branch if you capture...

    Battery Powered Chainsaw/Hedge Trimmer

    The batteries should have about half the capacity at freezing, below freezing things get progressively worse. If you store the batteries in a 30C°/85°F environment until you use them they might warm themselves and work perfectly fine. I still wouldn't use these saws in the winter.

    SRT Aerial Rescue

    I dont know how this is actually done, but here are my thoughts: It's theoretically possible, but very unsafe. If you tied of the standing leg of the rope you'd create a base anchor system, but this would leave the climber hanging on a loaded line which might be a problem (climber gets pulled...

    Need help working bugs out of SRT setup!

    Wow, that's the best DIY RW I've seen so far, I'm impressed! I dont see a "stopper" on it though, it's normally there to help it engage quicker and stay upright. Here is a pic of that thing on mine, it's just another bolt I added. the store bought ropewrench has a rubber thingy bumping against...

    Battery Powered Chainsaw/Hedge Trimmer

    These are all the top handle saws I can find on the German makita website, they dont seem to be available in america... They also market them specifically as pruning saws for arborists.
