I started this thread to avoid hijacking the Chamber of the Basilisk (Goblin's Lair) trip report when a question about a certain retrievable anchor came up.. I did not invent this anchor and there was a thread about it on the ACA website where the person who, I believe, first came up with it posted about it. All credit for coming up with the original buckle goes to walkerad from the ACA forum http://www.canyoneering.net/forums/showthread.php?3503-New-Releasable-Anchor-The-quot-Buckle-quot The discussion seemed to get a little sidetracked with others posting about their ideas about retrievable anchors. (I made a follow-up post on that thread back in November 2012 and no one seemed to have anything to say). I made a couple very minor modifications to this design with my own trial and error and now have a model I have used in the field several times. I’ve learned a bit each time using it, and like any system, it takes a little practice. In the meantime, my friend Dean (aka "Evergreen Dean") helped me test it during a canyon get-together in Boulder Utah where he pulled the retrieval cord while I weighted the anchor with my body weight. We used a small “baby” carabiner as the goal of this biner was not to support body weight, but rather to just pull down the un-weighted webbing anchor (edit: this also tested the buckle's ability to hold when the pull cord is weighted with someone on rappel). With my weight on the rappel strand, his force (weighing quite a bit more than I) did not budge the buckle in the slightest. He pulled so hard he actually bent the “baby biner” wide open. With my weight off the line, the webbing came down smooth as can be. This was very re-assuring, as with some other retrievables, they can cinch-up and tighten when weighted repeatedly. The buckle does not do this. I like it because it saves your rope, the rock, and any trees from being subjected to the abrasive force of a rope being used as the anchor (from observation, this seems tough on both the rope and the rock/tree). I think Webbing handles that task better and is easier to replace. Also, the fact that you are not pulling 100+ feet of rope back up through a rapid as you would using the normal biner-block through a rapid setup is a plus, as far as avoiding rope grooves. Some people prefer the CEM knot or Fiddlestick, but that involves using the rope itself over the rock, where the buckle doesn't. The buckle can be locked as a non-releasable for all but last one down. You can rig it in contingency mode just as you could any ordinary “webbing loop & rapid combo” anchor. Or, if you don’t need contingency, you can take the end of your rope out of the rope-bag and secure it to the rapid on the buckle and toss the rope bag over the edge (this wouldn’t work well in flowing water). As long as the rope & pull cord is long enough you only need rap down single strand and LAMAR deploys the pull cord as they go. A pull of 3-4 feet is all it takes to release (this depends on the amount of tail used, this should be approximately just less than one-half the length of the “keeper cord”. All this makes more sense when using it in person. Pictures will also help, but practicing with someone who has done it properly would be best. Perhaps others might decide that they like this system and agree that it is, first and foremost, SAFE to use, and also helps decrease rope groves and trash webbing. This is a pic of the anchor for Goblin's Lair. You can see the "permanent" anchor down low on the boulder, it was two loops of webbing when we got there (teal & light grey webbing). You can just barely see the rapid/rap ring on the loops. The black rope burns/grooves are to the left of the blue rap rope. Probably formed when peeps pull their rope ? The "buckle" is the blue webbing set higher (for easier pull) on same boulder. There is a really good horn on the boulder to keep the webbing slipping off, but it might look a bit sketchy from this angle? There is a longish tail on the blue rap rope (right strand), left side is the rap line going to the bottom. I'm standing on a solid platform and the pull cord (white line) is to the left of everything. The rapid on the blue webbing is connected to the rap rope and the actual buckle mechanism is as far away from the vertex of the webbing without being pressed-up against the rock as possible (this is very important). I wish I had video of how smooth the buckle released on this rap. It's about a 90-100 foot, mostly free hanging rap. The buckle is rock-solid when weighted but releases easily when pulled from the pull chord if the rap rope is not weighted. It is absolutely critical that you thread the webbing through the correct path through the mechanism and leave enough tail. But, if you leave too much tail, it won't retrieve. When you pull it, the rapid comes down with the rope and the webbing comes down with the pull cord.
