ZAED mini is our climbing brake assistant for climbers with a weight difference. It makes it possible for lighter climbing partners to belay heavier climbers. Like our famous first-generation device, it offers three adjustable levels of assistance – so you can dial in the right setting based on your weight difference, rope type, and belay style.
Unlike other devices, ZAED doesn't try to keep the belayer on the ground at all costs. Its core design principle is that the belayer is gently lifted toward the first bolt in a controlled manner. This results in a soft and smooth catch – and climbers around the world tell us that using ZAED feels like climbing with a partner of the same weight.
And the best part? You don’t need to learn new belay techniques. Just belay like you’re used to when climbing with someone your own weight – that’s it.
ZAED mini is a stripped-down version weighing only 100 grams, optimized for climbers who mostly climb in the gym or at modern sport crags with very low first bolts. The mini doesn't offer first-bolt support – because in such routes, the rope above the first bolt is simply too long to safely catch a fall. No device can override the laws of physics here.

FAQ
How's ZÆD different from other devices in the market?
1.: ZÆD allows for dynamic belaying for soft whippers.
2.: ZÆD allows for a quick rope pull by the climber for easy clipping in an unstable position.
3.: ZÆD allows to adjust the friction level according to the weight difference and the steepness of the climb.
4.: ZÆD can add friction even in steep overhanging terrain.

Is ZÆD certified after CE / EN / UIAA safety standards?
There's no CE / EN / UIAA standard for belay resistors yet. That's why we decided to have ZÆD tested by TÜV Austria after the strictest standards. You can check ZÆD's TÜV test certificate.
Why are there 3 levels to adjust ZÆD?
ZÆD is adjustable to the weight difference between climber and belayer. It's also adjustable to the steepness of the climb.
Level 1 allows a climber to be belayed by a lighter belay partner.
Level 2 allows a climber to be belayed by a much lighter belay partner.
Level 3 allows a heavy climber to be belayed by a much lighter belay partner. It also allows the installation of ZÆD in a steep overhanging wall.
What's so special about ZÆD's level 3?
This level's configuration still adds friction in steep terrain where a belay resistor usually couldn't flip up high enough to create friction. We designed ZÆD to overcome this problem, so it's a suitable device for even the strongest climbers in the steepest routes of the planet.
Does ZÆD add friction if I fall into the very first bolt?
ZÆD is designed for sports climbing which mostly happens in modern gyms. Here the first quickdraw is at a height where taller climbers can nearly clip it from the ground. If a heavier climber whip into such a low quickdraw while clipping the second quickdraw, having a significantly lighter belayer at the other end of the rope, it certainly creates a grounder, whatever device is used.
We can't change the physical length of the pulled out rope in such a scenario. In fact in gyms a lead fall with some rope pulled out for clipping is considered safe in recent climbing literature from the 4th (!) quickdraw on, anything below is considered a potential grounder, depending on the circumstances. Following that chain of arguments ZÆD mini doesn’t even pretend to provide added safety at the first quickdraw.
For climbers heading outdoors, far from perfectly bolted gyms or modern crags, ZAED pro offers extra protection at the first bolt. A ground fall risk still exists – no device can remove that entirely – but if the rope above the first bolt is short enough, ZAED pro provides significant braking support. This makes a big difference at old-school crags with notoriously high first bolts, like Frankenjura, Elbsandstein, or the Red River Gorge.
If you get into a climb with a potential whipper before the 2nd bolt, we highly recommend to preclip it with a clipstick or change the belay partner for someone heavier or just skip this route for that day and get into a less sketchy route and have a nice day with your lightweight belay partner.
