Ground retrievable canopy anchor

So what do you guys like?
I want to add a ground retrievable anchor to my arsenal but I’m not sure which way to go. It should be in the 3/4” rigging line range for working load. I have used steel ring friction savers in the past but kept the loads modest and would like an idea for something heavier.
 
I was just thinking about this at the job i had friday. I know I could make a retrievable anchor with some rigging rings, but I have had a hard enough time with anything retrievable. It's awesome when it works, but more than doubly frustrating when it doesn't.
 
One guy I work with loves that technique, but he has never used it for 3/4" lines, and I would worry about doing very heavy rigging on that system. Gotta use a really strong line to anchor with. I told him once that the line we were using was too skinny, and it would stretch. Imagine my shocked Pikachu face when it stretched enough to let a piece almost hit a propane tank. He let me switch the ropes after that. @39Buick , its a solid method, and has never gotten hung up, as you always have bi-directional control of the block/ring.
 
I wouldn't use anything retrievable for 3/4" rigging lines. I would just climb up there, set up a proper rigging point, come down and leave the climbing line there. Climb back up and retrieve when I'm done. That way you can properly cut away suckers and small branches in the way, really get it set up exactly how you need it. 3/4" rigging is serious business, as serious as it gets where I come from. Now, half inch rigging, that's a whole different ball game. Lots of retrievable options for that. Floating block on a 5/8" double braid makes a great option for half inch rigging, set and retrieve from the ground...

@southsoundtree have you had good luck with the static removable false crotch? You really fight a ton of friction on retrieval, with the rope taking a full 360 degree wrap on the stem the way it does...
 
For anything that requires 3/4 rigging line set it up close and in person. With those loads it requires a certain level of care.

Whenever possible I go with a static false crotch. Retrieval is easy, as long as it doesn’t imbed itself. Just use the rigging line as a 2:1 to pull it out.
 
One time I setup a 'lift' line on the setup just in case. I used a locking biner and small diameter cord/rope. the biner was clipped on somewhere to become a 'crane' to unjam the rigging on the way down.

To keep things a little neater I stashed the extra cord in a bag and kept it up with me as I worked down, paying out slack as I descended.

Not unlike setting up a 'lift' to unjam a throwline.

If we're using 3/4 line, chances are good we have a second and maybe third block or rigging point on the tree somewhere anyways so setting in person is already the way to go. Patrick's point about suckers is a good one. Twice in the last month we've had pieces get hung up on little epicormic stuff that should have been removed on the way up to set the rigging, especially true with Silver Maples.
 
there is a difference between retrievable and remotely settable. i can think of situations where a retrievable system for 3/4“ rope might come in handy. i rarely set my x-ring ringsling from the ground but often retrieve it. i spliced a ring and ring with xl ring‘s and 3/4“ rope for a terminal anchorpoint and with the right crotch and a small ring as a catch for the the retrieval ball i don‘t know why it would‘nt work..


if you do the math and work with a loadcell (easier than doing the math) a piece that requires a 3/4“ to stay within 10/1 WLL is‘nt all that big.

You can always make another. I know it won’t replace the memories you had with your beloved sling but you can make new and amazing memories. Your old sling would want you to carry on.

Unfortunately I don’t possess the skills but I’m sure I could find somebody to build me one. I saved the original rings.
