Thanks for the heads up Tom. Sorry to all who find it difficult to rig. It was supposed to be shipped with a laminated instruction sheet stored inside the metal tube. I guess ISC decided it was not needed although apparently it is.
Wow, You mean that some of our climbing gear can't take a pull on a 32:1 mechanical advantage?
Come on now! You would have to take a pretty good fall factor to damage a rope with a toothed ascender. It also might not hurt to use ropes meant for ascenders to be on them, IE kernmantle rope.
I...
So let me see if I understand this...
If you have a tree that you don't think could handle 2x rigging, the solution is to impart a sideways pull on it?
Trees are way stronger in a vertical plane. Applying rotational forces to a structurally questionable tree will get you into trouble.

I swear it was not my kid!
Nor was it me behind the camera, I just found it on the net.
Mixed emotions for me too. I did laugh but I would not be too impressed if someone did it to my kids

What do you mean emerging technology?
Dynamic has been around for a long time now. I still like to drive by stuff I put in almost a decade ago on windy days.
Watch it on a windy day and you will be sold on it.

I wonder if the stuff they put in divers googles would work on the fogging up of the glasses from sweat

It's called spit and it works great on my diving mask, never tried it on my safety goggles.

Thanks for the replys guys. We had a dry summer but the last month and a bit has been quite wet so I don't think it is drought. Lets hope it's just a natural needle drop like tom says.

Hey gang, I am not normally in this forum because bugs and disease was never my bag.
I am here now for that exact reason, I have a pine that has not looked so hot in the past few weeks. Needles turning yellow and falling off. Lots of cones in the top of the tree none down low. See...
This is my three year old son who has been up 20 ft in a tree proir to this. I rigged a practice srt line for someone else and my son said he wanted to climb too. Told him that as I raised him up, all he had to do was say stop if he got scared and I would let him down. All he kept yelling was...
To do a quick check for tree soundness, plunge (bore) cut the trunk with the bar vertical (see what is ma thread for over definition of vertical). You will only damage holding fibers the width of the chain unlike a horizontal plunge, just watch the chips coming out.

another technique you could use as prevention in a pinch is to undo your lanyard and attach both sides to your front tie in. You would still get pulled forward but you will not get crushed into the tree.

Have multiple judges, take hi res before and after pictures plus after walkaround, each judge scores out of ten, drop high and low and take average like olympics. Points off for overpruning, bark tears, hangers, missed deadwood. If all trees are similar in size you could impose a time limit...
I have worked from a 25 ton 125 ft crane that the operator had a man bucket on. I cut some branches to thin out the tree and hung some chokers before climbing into the canopy to remove. Reaching over the house to a large oak I gave the signal to extend the boom and heard from far far away...
