The REVO is the only automatically locking belay device which has a completely panic-proof locking mechanism.

The REVO has no method of over-riding the locking mechanism, during belaying, or when lowering a climber. 

• Bi-directional: the locking function works regardless of the rope direction.
• Intuitive belaying method, which requires no changes to standard belaying technique.
• No need for a specific locking karabiner.

All of these USP's contribute to make the REVO the safest belay device available.
