Guide to Buying a Belay Device

When it comes to belay devices, there are two main categories: assisted-braking and non-assisted-braking. Many people espouse the value of not relying on the device to do the work for you. Others say that an extra layer of security is always a good thing. Regardless, it’s important to be aware of the pros and cons of the devices available.

 

Belay devices come in many different styles. From left to right, Camp Figure 8, Black Diamond ATC, Edelrid Mega Jul, Petzl GriGri 2.

Non-assisted-Braking

This category includes devices such as the Petzl Reverso and the Black Diamond ATC. Old-school plates and figure-8s also fit into this category, although they are rarely used these days. Proponents of this type of device argue that it forces belayers to be attentive and to develop good belaying habits. Other advantages include a lack of moving parts – which means less maintenance – and commonly having capacity for two ropes in the one device.

The ability to have two ropes in one device helps with longer  retrievable rappels that join two ropes together (although single-rope devices can be used for the same task, they require a more complex set up). It’s also required for half- and twin-rope climbing, which is often required for more adventurous climbs.

Many devices in this category have the ability to be used in “guide mode”, which is a form of assisted-braking that only works when top-belaying. Guide mode does have its drawbacks, such as making it very hard (and potentially dangerous) to lower the climber. 

These devices put total control in the user’s hands, which means the user has to be alert and responsive at all times, but it also means the devices tend to be quite versatile and are viable for almost any recreational climbing scenario.

Assisted-Braking

It’s important to note the “assisted” in “assisted-braking” – these devices are designed to help you hold the rope, not to hold it for you. Always follow the manufacturer’s recommended belay/rappel technique.

Non-mechanical

This includes devices such as the Edelrid Mega Jul and the Mammut Smart, which rely on the geometrical design of the device to provide the assisted-braking power. They’re great in that they require less maintenance than devices with moving parts, they tend to be cheaper, and they are more likely to accommodate two ropes. Unfortunately, they tend to under-perform in some areas. For example, complaints about the Mega Jul tend to focus on the awkwardness and difficulty of lowering/rapelling.

Mechanical

This includes devices such as the Petzl GriGri line and the Trango Vergo, which rely on cams responding to the force generated in a fall to lock the device up. These devices offer the greatest security available (provided they are used correctly, of course). Drawbacks are that they require sometimes-complex manipulation and they typically don’t have capacity for more than one rope at a time. These devices tend to allow very little rope slippage during a fall, which some people say is a reason not to use them when trad climbing as impact force (which is increased by a sharper fall) can be a concern for traditional protection. Others say that the difference in impact force when using a mechanical device vs a non-assisted-braking device is negligible.

For beginners, mechanical devices can be intimidating but they are well-worth taking the time to learn to use. They offer an extra layer of security and can help reduce belayer-fatigue when projecting hard routes that require plenty of rests.

Conclusion

There has been a long-standing debate around the appropriateness of new climbers learning to belay using an assisted-braking device. The idea is that it’s better to develop good technique and habits with the old-school devices that require 100% attention at all times. The counter-argument is that it’s good for a new belayer to have an extra layer of security. There really is no right answer and if you are buying your first belay device, we would recommend talking to the people you will be climbing with and seeing what they prefer.

The most important thing to consider is what type of climbing you will be doing. From there, you can narrow down the list of appropriate belay devices and choose one that will best suit your needs. The GriGri has dominated the assisted-braking market for a long time but recently there have been several viable alternatives released or announced (e.g., the Trango Vergo and the Wild Country Revo). For non-assisted-braking, the Black Diamond ATC Guide and Petzl Reverso offer great functionality and versatility but other options exist that have a few fancy features (e.g., the DMM Pivot).
