Let’s Talk About Petzl Zigzag Plus Descender
The Petzl Zigzag Plus Descender is a mechanical Prusik designed for arborists and tree care professionals who demand precision, fluidity, and versatility in their climbing systems. Petzl, a trusted name in climbing and safety equipment, has created a device that aims to streamline tree movement using classic Prusik pulley system techniques. I have always been interested in optimizing my climbing gear to increase my efficiency and minimize fatigue.
My interest in the Petzl Zigzag Plus Descender arose from a need to replace my aging friction hitch system. It was slow and inefficient compared to more modern mechanical devices. The promise of smoother ascents and descents, along with the ability to use it on both doubled and single ropes, was incredibly appealing.
The Petzl Zigzag Plus Descender came well-packaged. Upon opening the box, the first thing I noticed was its robust construction and the feel of the materials used. It felt substantial and ready to handle the demands of daily tree work.
Compared to other mechanical Prusiks like the ART Spiderjack 3 or the DMM Pinto Rig, the Petzl Zigzag Plus Descender stood out due to its simplicity and the reputation of the Petzl brand for reliability. I chose the Zigzag Plus for its intuitive operation and the swivel attachment point, which I hoped would prevent rope twisting.
My initial impression was one of cautious optimism. I was eager to get it into the field and see if it lived up to the hype, but I also knew that mechanical devices can have a learning curve.
Real-World Testing: Putting Petzl Zigzag Plus Descender to the Test
First Use Experience
I tested the Petzl Zigzag Plus Descender during a tree pruning job in a large oak tree at a local park. The conditions were dry, with a slight breeze, providing a good environment for evaluating its performance. I used it with a 12mm Petzl low-stretch kernmantel rope.
The Zigzag Plus was surprisingly intuitive to use. The technique mimicked a traditional Prusik hitch, making the transition relatively seamless. It locked reliably on the rope when the friction chain extended, and the release lever allowed for controlled descents.
One minor issue I encountered initially was adjusting the pressure on the release lever to find the optimal descent speed. However, this became more natural with practice.
Extended Use & Reliability
After several months of consistent use, the Petzl Zigzag Plus Descender has proven to be a reliable and durable piece of equipment. There are only minor signs of wear, mainly superficial scratches on the steel components. The aluminum body still looks new.
Maintaining the Zigzag Plus is straightforward. Cleaning involves brushing off debris and occasionally lubricating the moving parts with a silicone-based lubricant. This simple maintenance routine ensures smooth operation.
Compared to my previous friction hitch, the Petzl Zigzag Plus Descender is a significant upgrade. It is faster, more efficient, and reduces fatigue, especially during prolonged climbing sessions. It has definitely exceeded my expectations.
