Mammut Smart 2.0 Belay device

A lightweight tube‑style belay device with passive assisted braking, designed for sport and rock climbing. Suited to belayers who want dynamic brake assistance to help arrest a fall during lead and top‑rope belaying.

Benefits

• Passive assisted braking: geometry helps lock the rope and catch a fall if the belayer fails to apply full brake force.
• Compatible with ropes 8.7 – 10.5 mm: covers common single‑rope diameters for sport climbing.
• Lightweight (80 g): reduces pack and harness load without sacrificing function.
• Works for lead belaying and abseiling: multifunctional use on the wall.
• Recommended with a round‑profile HMS carabiner (Smart HMS): improves rope position and assist function.

Typically used on crags and in climbing gyms for lead belaying, top‑rope and abseiling. It is not an automatic catch system—continue to use proper belay technique and vigilance.
