Tube Belay Device vs Assisted-Braking Device
Both require an attentive belayer with a hand on the brake strand. An assisted-braking device adds a mechanism that helps lock the rope in a fall.
| Tube device | Assisted-braking device | |
|---|---|---|
| Braking | Depends fully on the brake hand | Mechanism helps lock the rope |
| Rope range | Wide | Narrower, check the rated diameters |
| Rappelling | Easy on two strands | Varies by model |
| Weight and cost | Light and cheap | Heavier and pricier |
| Lowering | Smooth with practice | Needs handle technique |
| Soft catches | Easy | Takes practice |
Choose Tube device if
- You climb multi-pitch or rappel often
- You use a wide range of ropes
- You want light, simple gear
Choose Assisted-braking device if
- You climb at the gym or sport crag
- You belay heavier partners
- You want an extra margin when projecting
The bottom line
Learn proper technique on whichever device you use, with instruction. Many climbers carry an assisted-braking device for sport and gym climbing and a tube device for multi-pitch.
