The Zigzag mechanical prusik for arborists combines all the individual pieces of gear being used in doubled rope climbing into a single mechanical prusik that operates just like climbing on a hitch and prusik in DdRT.
Friction is managed by running the climbing line through the linked "zig-zag" pattern of rings. The top ring is a lever; pushing down on this lever releases pressure in the rings, and the climber descends - just like using a prusik cord. Release the lever and the Zigzag jams, stopping descent. The climber has control over the rate of descent through varying the pressure on the Zigzag lever.
The attachment point for the climbing harness on the Zigzag is on a built-in swivel for twist-free ropes while you climb, which also helps make advancing the Zigzag smoother. The Zigzag has an eye for attaching the end of your climb line directly to the device in doubled rope climbing. Slack tending the Zigzag is made super-efficient with the built-in, sealed ball-bearing pulley.
The Zigzag accepts ropes from 11.5-13mm, so it works on your favorite 7/16" and 1/2" climb lines.

“ I am a newer climber. My primary climbing style is DRT. I was climbing with a VT on an O rig for a good deal of time entering the canopy with the body thrusting technique. This device is very nice. It is much more reliable than my VT. It always grabs when its supposed to. No need to change over to an 8 in a long decent. Moving around in the tree is very smooth. Built in slack tending pulley is very nice too. The device has had some controversy and rightfully so. I give it a very thorough pre climb inspection and it looks perfect every time. I think Petzl is guilty of catering to rock climbers first and tree climbers second. I would like to see the device less compact and more substantial and i think more doubters would get on board. No midline attachment is a big drawback. I use it mostly for pruning jobs not takedowns when spurs aren't an option. I set a floating false crotch with a ball bearing pulley. they recommend a spliced eye but you can use a bowline and call it a large spliced eye. I've used a double fishermans with the tail facing out and never even come close to disengaging the hitch. I cant get a spliced eye through the device so you have to either leave it on your line from climb to climb or feed it from the tail of your climb line. Not a deal breaker but it does slow down the work. For any drawbacks it may have are quickly forgotten once in a tree. That's when you appreciate it fully. ”

“ I've been climbing since the 80's and I love this thing. I bought a SpiderJack and never liked it much so I ending up not using it. This makes my day a little easier and at this point I need all the easy I can get. God bless.”

“Despite the recall and some negative reviews on this mechanical Prussic, I love the device. It makes my climbing life much more fun, easier and efficient. I feel very comfortable with the device and it is very user friendly. I will be purchasing another very soon to have on my other climbing line. Two thumbs up!”
