Retrievable Canopy Anchor Set Within Tree

[Treespasser]

Hi all,

 

Pretty much all of the SRT videos I've seen on youtube install the climbing line with a throwline,

and I understand this works well large trees from personal experience with DRT.

Though personally the majority of trees I work on are under 20m, so don't necessarily warrant using a throwline, I usually just squirrel up using DRT.

This brings me onto my question as I'm using SRT a bit now.

 

If I use DRT to get to the top of a 15m tree to save time messing around with a throwline... how do I efficiently set up a canopy anchor that is retrievable, and that has a set (minimal) amount of tail on the working end?

The primary way I imagine doing it would be to tie a normal alpine butterfly anchor and attach a secondary line to that in order to retrieve... but that leaves me with a stupid amount of rope on the working end to pull through redirects all the time. Or the other way I see is to haul up x amount of rope and use guess work looking at the end of the working line, and use some kind of running bowline on a bight to tie the anchor.

 

Any help or suggestions would be greatly appreciated.

Use a shorter rope for smaller trees.

Pull up enough rope to reach the ground for retrieval then tie the butterfly ( uses up some of the working end) See .. The climbing arborist video srt canopy anchors. The last one which you can advance with is useful and I use an old cambium saver + krab to achieve the same thing.

i just return to the canopy anchor at the end of the srt climb and  untie and dessend  using drt.( i try and make sure the splice is up at the tie in point)

i climb on a bulldog bone so this change over is simple.

if iam on a pole i choker off a srt line and just tie the end of my climbing line onto the loop and pull the knot down when iam on the ground.

iam sure there are lots of better ways than the above but they work  and are simple.

Cool cheers for the replies!

Carlos, where did you order your Bulldog Bone from? did shipping cost a bomb? I can't seem to find it on UK online stores

you cant buy them in shops, they are made by a guy in the states, he is a member on here called "surveyor" ( i think thats it).

the shipping was ok but i did have to pay import duty which bumped the price up a bit, although my mate didnt  get caught by customs.

a very good and easy to use device, i use it all the time unless i want drt then i use a lockjack.

there are a few threads on here about the bulldog bone, could be worth a trawl through if you are thinking of getting one.
