    Spider Jack+ Rope Wrench=SRT?

    I have not used the Spiderjack but I have used the Lockjack. Nice tools. But neither one is even close as versatile as the Uni. In use it definitely does not feel too bulky. Dave

    Port-a-Wrap, Bollards, Etc.

    We use the RC 2000, which also is sold for the price quoted of $210. This is the one you will want if you want to surpass what the Porty is capable of. The picture initially showed is the RC 1000. And though it is better than the large Porty, it is still in the same category with a 2.5"...

    Climbing Techniques

    Tony, my apologies. I did not intend to diminish the difficulty and challenges of making a living as an arborist. It takes very little equipment to be a top quality and productive arborist. And you certainly do not need a Unicender. My statement was directed more towards those willing to...

    Climbing Techniques

    TM, I'm pretty sure Moss has a good understanding of the technique you are promoting. I see his choice of wording as lack of agreement more than lack of comprehension. I feel the same. You keep repeating that your techniques are superior due to the fact that you make your living...

    Climbing Techniques

    TM - What is the advantage here? Do you set a friction saver when working in this mode to prevent damage on thin-barked trees? I'm sure by now both you and TM have tried out the Unicender and found it lacking? How so? Absolutely. I have been climbing a long time and to stop learning...

    Question on spur pads.

    The aluminum "Cadillac" pads are cast so the bend is parallel to the spur shank. This will hold the shank at a less then perfect angel for many climbers. The "Stiff Wraps" have the steel brace set at an angle to the shank placing the top of the shank more to the center of the leg and at a better...

    Oak tree losing leaves in Summer (July)

    With three trees in the same yard, two of which are doing well, and one doing poorly, it is doubtful this is environmental. This tree is under stress. How about some more pictures as suggested, including the root flare and the other healthy trees. Before something can be corrected, we need...

    friction hitches,how safe are they!!?

    Nice post, Shaun. :agree2: Have you tried the Unicender? It is one specialised tool that can do many things very well. Dave

    Advice on dead wood rigging

    Arbor pro, you are correct in your assessment of the situation being a concern. Dead cottonwoods have no reliability. Are you sure you can't get a longer stick in there? Check with local truss companies. They will often have a lightweight (small) crane with a long stick. I have used...

    Best Saddle

    What is best Ford/Chevy, Stihl/Husky, blondes/brunettes? There is NO best. There IS what is best for you. Try them all, see which you like. Dave

    footlocking

    I agree. Having used all the above techniques it is easy to see why ascender systems have become so popular. Dave

    Reaction Wood

    These are not representations of fasciation. Sinclair, Diseases of Trees and Shrubs, "This term connotes abnormal flattening of plant organs, usually stems, as the result of the change in form of the apical meristem from a minute dome to a jagged row of generative cells perpendicular to the...

    Reaction Wood

    I probably was too vague with my question. These unusual reactions do look to be adaptive growth and with lab work should prove cellular changes consistent with such. What I was questioning was what triggered that particular response. Given similar stress parameters, most trees do not...

    Awww, found another picture of the tree. Dave

    Reaction Wood

    I thought I had a better picture of this tree but hopefully this shows the degree of twisting in the trunk. It is radical. Looks like a piece of rope. This is a silver maple, approximately 100 years old. There is another tree, same age, same species, probably from the same nursery, about...

    Deep root fertilization, helpful or scam?

    How about some pics? If there are 12 other Spruce trees in the same location that are doing well it is not likely that location is the problem. Dave

    You've done very well then.:cheers: Dave

    How to trim back this Oak tree a little.

    Beautiful tree. Definitely just trim it away from the house. Try to accomplish what you need by reducing the limbs in length as opposed to cutting them back to the trunk. Dave

    New Stainless Portawrap IV

    I can't imagine you are going to see any improvement over the aluminum you already have. They work well if kept within their design limits. If you want something that will take up about the same amount of space in the truck, but has more depth and is rated to hold more than twice the load of...
