Grivel Master Pro Belay Device
Overview
The Grivel Master Pro was created for belaying and rappelling. It is a versatile, dynamic and reliable tool to minimise the force transmitted to the anchors, the belay and the wear and tear over time of the rope.
It can also be used in guide mode as a self-locking plate, to belay a second.
The two “horns” that are placed at one of the two ends have two main functions: Additional braking with thin ropes by passing them below the horns themselves, and the possibility of hooking a webbing ring for a release maneuver.
Its body has been designed with a series of holes on the sides to reduce weight, but above all to disperse the heat and consequently not to overheat during prolonged use.

I’ve used the Grivel Master Pro for several multi-pitch climbs and it performs reliably in both belay and rappel modes. The horns are useful for thin ropes and the guide mode works smoothly when belaying a second climber. The device feels solid and the heat dispersion is noticeable during long descents.

This device is a great all-rounder. It handles dynamic loads well and the self-locking feature in guide mode gives me confidence when managing a second climber. Lightweight and durable, it’s become my go-to for both ascent and descent.

The Grivel Master Pro works as expected in standard belay and rappel situations. The horn design helps with thin ropes, though I found the guide mode slightly less intuitive at first. Once adjusted, it’s reliable and effective.
