Yeah, by all means use the CA test as a jumping off point for the lifetime(s) long task of the study arboriculture (...and dendrology, mycology, entomology, soil science/geology, biochemistry, hydrology, microbiology, action/adventure physics, forest ecology, urban ecology, business law...
Send a direct message to @surveyor on here, he's one of our resident innovators. He makes both the BOLA and the Compact Bulldog Bone (BDB), another device worth looking at...just be careful if you dive into the BDB thread on here, it's so big and full of rope recommendations, rave reviews, and...
If you have been climbing/rigging/pruning for a year or two, the study guide is all you need (https://wwv.isa-arbor.com/store/product/7/cid/43/). I over-prepared, and so have most other people I've talked to about it or trained. Just don't buy the audio study guide, it's one of the greatest...
I agree with both of you, the basic skills are the same, but for example, I'd never try to turn a tree with an intentional dutchman on a residential/commercial property because the stakes are too high. The worst that happens in a timber falling context is wasted board feet.

I am a little fussy about lanyards and have a few different ones. My main lanyard is CE style with a CMI double attachment pulley because I don't like stuffing the eyes of the hitch cord between the cheeks of the PINTO. I have 2 zigzags that I use all the time, and one lives on a 65ish' hank of...
I also like the Arborwear tech pants and Prana. Mountain Hardware, Carhart, and Duluth have some nice pants too. Duluth also has some great hot weather panties which is a big part of the equation for me. On the cheaper tip, decent hot weather pants are available from Cintas and Red Kap. I had a...
As a plus-sized climber, I LOVE remote settable/retrievable solutions and have used them quite a bit, but there's another aspect of how I have used these techniques in practice. Usually, I am trying to either use a rigging point that's away from obstacles including the stem of the tree...
Anyone do this sort of thing themselves? I bought a used truck and the dump body is well used, but still pretty solid. I did a little google-fu, and came up with "abrasive media blasting", since it seems like sand isn't used too much anymore. What abrasives have you used? Did you buy or rent the...
A decent grinder to sharpen would be a good investment, you can work with the chains you have for the time being and revisit the breaker and spinner later. Look into buying spools of chain online, Oregon and woodsman can be had a decent prices and if you fold it into a larger order or buy enough...

I saw this a while back and have been constructing one myself, I would just throw out there that he is using toothed ascenders so there is no way for the roller tend his system downward...
Does anyone know of any truly useful vendors (AM Leonard, Sherrill, Forestry Supply, Site One, Baileys, Rainbow, etc...) that offer attainable net 30 accounts to small businesses and report to Dun & Bradstreet? Gemplers is great, but I am tired of pouring over Quill's and Uline's websites...
You'll love it, I have one at work. If you're using a BMG on it, the machine can pick up bigger pieces than the grapple can clamp, especially if they are large enough diameter that the tongs can't get past the midpoint. I'm sure the manufacturer would disavow this technique, but I use a 3/4"...
What do you think about new one ton pickups? Make, engine, transmission, fuel, dump, toolboxes? What has worked for your business? What about contract climbers? As a daily driver? As a light or spare chip truck? I'd value any input, especially about make and drive train.

We have big pvc pipes on the roofs of most of our trucks to keep the poles out of the weather, but I was wondering if anyone uses linseed oil, polyurethane, paint, or something else to help their poles last longer, and maybe more pleasant to use.

Just to make it explicit, that is an endless loop splice with each end tapered and buried in the other side after a crossover?
