The device felt familiar in hand, its form factor not drastically different from other tube-style devices I’ve used.

Performance was immediately noticeable when belaying a leader; the device fed rope smoothly, and the braking action was predictable and firm. The real test, however, came during the lowering process. Clipping a carabiner into the designated secondary hole and using it as a lever allowed for incredibly fine control over the descent speed.

I encountered no significant issues during this first outing; the device simply performed as advertised, providing a higher degree of confidence and control during the lowering of a weighted climber. The diagonal cable design prevented any rope-induced snagging or jamming, which is a common annoyance with lesser designs.

Extended Use & Reliability

Over the subsequent months, this belay device became my go-to for a variety of climbing applications. I’ve used it extensively on granite multi-pitch routes where rope drag and precise control are essential, as well as on sport climbing days for leading and top-roping. It has also seen use on ice climbing trips, where the added security of the lever system proved beneficial in cold, gloved conditions.

Durability has been excellent; despite frequent use, including occasional drops onto rock and dirt, there are no significant scuffs or performance degradation. The aluminum construction has held up remarkably well, showing no signs of bending or structural compromise. Maintenance has been minimal, requiring only a quick rinse and dry after particularly dirty excursions and an occasional wipe-down.

Compared to the more basic tube-style devices I’ve used in the past, the PIU 2 offers a superior experience, particularly for controlled lowering. While more complex assisted-braking devices exist, this model strikes a fantastic balance between simplicity, functionality, and enhanced control for its price point.

Breaking Down the Features of C.A.M.P. Cassin PIU 2 Belay Device

Specifications

The C.A.M.P. Cassin PIU 2 Belay Device is constructed from durable aluminum, contributing to its robust feel without adding excessive weight. Its compact design makes it easy to manage on a harness. The device is rated for single ropes between 10 mm and 11 mm in diameter, and for double ropes ranging from 8 mm to 9 mm.

This broad rope compatibility is a significant advantage, allowing for consistent performance across various climbing disciplines and rope types. The inclusion of a second carabiner hole is its defining feature, specifically designed to work with CAMP’s HMS Nitro and HMS Compact carabiners for leverage. The device weighs in at 8.1 oz, which is a reasonable weight for a belay device that offers enhanced functionality.

Its application spectrum covers sport climbing, rappelling, and multi-pitch routes, demonstrating its versatility. The belay type is classified as Manual Catch, but the integrated lever system elevates its control capabilities significantly beyond a standard manual device.

Performance & Functionality

The primary job of any belay device is to safely manage the rope and arrest falls. The PIU 2 excels at this, providing smooth rope feeding for the leader and reliable, firm braking when needed. Its unique selling proposition, the second carabiner hole for controlled lowering, performs exceptionally well.

By clipping a carabiner into the designated slot, you create a lever that allows for incredibly granular control over rope tension. This makes lowering a second climber, or even rappelling, much smoother and more controlled than with a traditional tube-style device. The teeth on the device have been optimized to handle the specified range of rope diameters effectively, ensuring consistent friction.

Its strengths lie in its dual functionality: it’s a reliable belay device for leading and a superior tool for controlled lowering. A potential weakness, if one can call it that, is the slight learning curve associated with mastering the lever action for precise control, though this is minimal. It exceeds expectations for its intended use, especially considering its accessible price point.

Design & Ergonomics

The build quality of the C.A.M.P. Cassin PIU 2 Belay Device is immediately apparent; the aluminum feels solid and well-machined, with no sharp edges or rough spots. The diagonal cable design is a thoughtful touch that prevents the rope from rubbing directly against the device body, reducing wear and potential jamming.

Ergonomically, the device is comfortable to hold and manipulate, even with gloves on, thanks to its streamlined profile. The primary belay slot is well-proportioned, and the secondary carabiner hole is precisely placed to offer optimal leverage. There is a very slight learning curve to mastering the delicate art of controlled lowering using the lever, but it is intuitive enough that most climbers will adapt quickly.

The overall design is focused on functionality, with subtle but effective details that enhance its real-world performance. The finish is utilitarian but durable, suggesting it’s built to withstand the rigors of the climbing environment.
