    Line launcher

    I climb in so many different contexts, for so many different reasons, pulling the bag back from a big slingshot throw to a point where I can work with it works well for me. Finesse in everything, whatever works best for an individual climber is best for sure! -AJ

    Line launcher

    On a recent job I created a high rigging point (80') on a big pine to support a tree I was removing off a roof. It took me 3 slingshot throws to put the ace in the hole. First shot was 1' too low, second shot was correct height but a foot or so to the side and deflected off the trunk. Third shot...

    Line launcher

    It's that weird and challenging artillery problem where the charge (PSI level) will create a more or less arcing throw per height and angle. The engineering and build to have the laser pointer automatically adjust per PSI level would cost quite a bit more than the spud gun no doubt. For tree...

    Line launcher

    In the demo vid placing the line in a tower the operator throws up a line snarl. Goes with the territory, no fault of the gun ;-) The ball valve is a kind of safety feature I suppose since it requires a deliberate slow pull to maintain good aim. Some form of trigger release that doesn't violate...

    Squirrel Damage

    Yes, that needs to be ruled out. It's interesting, it is vaccine based. For example the mouse and rat birth control vaccine does not effect squirrels. -AJ

    Squirrel Damage

    You need the #1 squirrel predator, the fisher. A bit of an undertaking to introduce a fisher population ;-) There is now birth control laced bait food available to control mice and rats. There is an effort in the UK to develop a squirrel contraceptive agent, info here...

    New device from ISC

    Massive oversight, @surveyor basically started all this with his link friction devices culminating in the BDB! -AJ

    New device from ISC

    Practicalities. On the other hand Petzl likely has an in-house IP legal team. Sometimes the "big boys and girls" like to discipline the competition because they can. It will be interesting to see how it plays out. AJ

    New device from ISC

    I may be more excited about the ISC "UltraLink Small" as recommended by ISC for the Apex tether attachment. I'll no longer have to build my own stainless Slic Pin bow shackles as fun as it is ;-) The Reflex appears to be an awesome device...

    New device from ISC

    Great news that it "self adjusts" and functions well on 9mm! -AJ

    New device from ISC

    Takes a long time for a full patent to go through, doesn't fit real-world development and marketing return on investment necessities. A lot of products carry "patent pending" marks, it is like "provisional" patent protection. It's no indication that ISC is having problems with the Zig-Zag...

    Working on putting great horned owl young back up in trees April, 2025

    Thx again Cory. The climbing rope, Yale Pink Moon 11.7mm, was clear of the nest pulled out in either direction, I think I pulled it out from the backside of the tree to guarantee no contact with the nest. I've got a chunk of stainless bow shackle near the end of my lanyard so needed to be extra...

    Tom Wessels on coevolution, efficiency, and mutualism in stable forest ecosystems

    He is my hero, such a good teacher. I snuck him into an illustration for a book on old-growth forests, I need to let him know, book's been out a few years anyway ;-) I should've put his right arm/hand on the tree. Oh well, deadlines are not fun ;-)

    carpenter ants and scammers

    Some interesting work by Tom Wessels (Reading the Forested Landscape), the well known "forensic ecologist". He has described how after an initial injury (wind damage or hit by falling limbs or other trees) forest eastern hemlock he's studied suffer progressive fungal invasion into damaged areas...

    Cute vid

    Sorry for your friend’s dad’s situation. I was on the flip side. 1962, I was 6.5 years-old suffering a severe immune response to the measles one year before the measles vaccine was widely available to the U.S.public. As a result of my body’s response to the infection I suffered lifelong...
