VERSO
Petzl's lightest belay/rappel device with Adaptive Rope Control technology
The VERSO is a simplified version of the REVERSO³ offering a lighter and more compact option for climbers looking to further reduce the weight/size of their rack of gear. The asymmetrical V-shaped grooved friction channels adapt the friction for better control using our ARC (Adaptive Rope Control) technology.
* Ultra-light design:
- 31 % lighter than the Reverso³
- hot-forged aluminum
- Weight: 57 g (2 oz)
* Single device for all ropes:
- single ropes ≥ 8.9 mm
- half ropes ≥ 8 mm
- twin ropes ≥ 7.5 mm
* ARC technology adapts to the diameter of rope used by increasing or decreasing the braking friction on the rope according to its diameter and conditions
* Increased friction on thinner ropes
* Adapted friction for efficiency with larger diameter ropes
* Asymmetrical grooved sidewalls decrease friction when taking in slack for greater ease of use
* Super compact design is easy to use and doesn't take up much space on your rack
* Rope friendly design separates the two strands of rope when belaying with half/twin ropes or while rappelling thus helping to prevents kinks
* Stiff keeper cable will not get sucked into the device, helps maintain the optimal position during use, and aids in preventing loss during transitions
* Usage diagram engraved on device for ease of use
* Use with symmetrical shaped locking carabiners (Am'D or OK) to maximize efficiency no matter which end is closest to the device

Nice and LightFirst, the positive. It's super light and, when not in use, hangs on a relatively short keeper cable. It feeds rope smoothly and locks up nicely on the 11, 10.5 and 9.9 ropes on which I tried it. It's also been very controllable on the shorter raps on which I've used it.
Second, the not-as-positive. It has somewhat smaller holes that could be difficult to fit frozen, stiff ropes through. It's lightly built and I think sandy, wet canyoneering ropes would nearly cut the thing in half. Also, due to it's light construction, I don't think it would manage heat as well as some of the heavier devices, though I haven't used it on any long rappels yet.
Overall it's a nice product, but it's built for a specific purpose. For the types of things I generally do, I like the versatility and durability of the ATC Guide better, but when those features aren't as relevant, this is the little guy I'm using.
