CMI Figure 8’s Review

Let’s Dive into CMI Figure 8’s

The CMI Figure 8’s are a staple in the climbing and rescue world. Crafted by CMI, a reputable name in the industry, these devices are designed for controlled descent, specifically rappelling and belaying.

My initial interest in the CMI Figure 8’s stemmed from a need for a reliable and durable rappel device for multi-pitch climbing and canyoning. I needed something that could handle various rope diameters and provide consistent friction.

Upon unboxing, the CMI Figure 8 felt solid and well-constructed. The 6061-T6 aluminum alloy gave it a robust feel, while the hardcoated finish suggested a long-lasting product. The weight was surprisingly light, making it ideal for carrying on long expeditions.

Compared to other figure 8 devices I’ve used in the past, like the Black Diamond Super 8, the CMI Figure 8 felt noticeably more substantial. I picked this one primarily due to CMI’s reputation for quality and the specified 10,000 lb breaking strength, which offered a significant safety margin.

My first impression was one of confidence. This wasn’t just another piece of gear; it felt like a well-engineered tool ready to handle serious situations.

Real-World Testing: Putting CMI Figure 8’s to the Test

First Use Experience

I first tested the CMI Figure 8’s on a local climbing crag with a 100-foot rappel. The environment was dry and sunny, providing ideal conditions for familiarizing myself with the device.

The performance was exceptional, offering smooth and controlled descents. The figure 8 was easy to load and manage, even with gloves on.

There were no surprises after the first use, only confirmation that it performed exactly as expected. The friction was consistent, allowing for precise control over the descent speed.

Extended Use & Reliability

After several months of regular use in various environments, the CMI Figure 8’s have held up remarkably well. I’ve used them in sandstone canyons with abrasive conditions and alpine environments with exposure to rain and snow.

The hardcoated finish has resisted scratches and wear, maintaining its smooth surface. Minimal maintenance is required – a quick wipe down after use is usually sufficient.

Compared to my previous rappel devices, the CMI Figure 8’s have proven to be significantly more durable and reliable. Their performance consistently exceeds expectations, offering peace of mind during critical rappels.

Breaking Down the Features of CMI Figure 8’s

Specifications

The CMI Figure 8’s are crafted from 6061-T6 Aluminum Alloy. This is a common material in climbing gear because of its strength-to-weight ratio.

The breaking strength is rated at 10,000 lbs. This is a crucial spec for safety as it indicates the maximum force the device can withstand before failure. The belay type is a manual catch, requiring the user to actively control the rope.

The climbing hardware type is specified as “Belay & Rappel,” highlighting its dual functionality. Its application is suited for Sport Climbing and Rappelling.

The Figure 8 itself measures 13.5 x 7.5 cm, weighing 117 g, with a break strength of 8000+ lbs. The Rescue 8 measures 17 x 15.5 cm, weighing 221 g, with a break strength of 10,000+ lbs. These dimensions are ideal for handling various rope sizes comfortably.

Performance & Functionality

The CMI Figure 8’s excels at providing controlled descents during rappelling. It allows the user to adjust the friction by varying the rope configuration.

A key strength is its ability to handle a wide range of rope diameters. A slight weakness is that rope twisting can sometimes occur.

The product meets, and often exceeds, expectations. Its simple, yet effective design guarantees safety and functionality.

Design & Ergonomics

The build quality of the CMI Figure 8’s is exceptional, thanks to the 6061-T6 aluminum alloy. Its weight is balanced, feeling neither too heavy nor too light.

The figure 8 design is intuitive, offering a small learning curve. The hard-anodized finish makes it feel durable and comfortable in hand.

Durability & Maintenance

With proper care, the CMI Figure 8’s will likely last for years. Its robust construction and hardcoated finish protect it from wear and tear.

Cleaning is simple: just rinse with water and dry thoroughly. Regular inspection for any signs of damage is recommended.

Accessories and Customization Options

The CMI Figure 8’s themselves don’t come with accessories, as it’s a standalone device. However, it is compatible with a wide variety of carabiners and ropes.

There are no specific customization options, but you can choose between different sizes and designs (e.g., standard figure 8 vs. rescue figure 8). The Rescue 8 offers increased friction and heat dissipation, making it suitable for longer rappels.
