The Smart safety device has been specially designed to meet the needs of the constantly growing group of indoor and sports climbers. It dynamically brakes the climber in an accidental fall, and locks even at low levels of force exerted by the user. In situations where the user has a sudden shock, the function corresponds to the reflex movements of the human body. Suitable for all current HMS carabiners and simple ropes from 8.9-10.5 mm in diameter.

    Comments about Smart Belay Device:

    I've only used mine for a full day at the crag so far, but love it. I like the security of how it locks off easily and dynamically. Locked securely on my new (read: slippery) 10mm rope. Great for new belayers after a quick instruction set. Read the directions and you shouldn't have any problem lowering smoothly. Make sure to use two hands and my climbers can't even feel when I release it from lock now. Simplicity of a non-mechanical device like a tube, yet near auto-locking convenience of a grigri style device without the price. Remember its marketed at auto-assist and not auto-lock, but one should always have their brake hand on the rope no matter what device you are using.

    Comments about Smart Belay Device:

    The Smart belay device does exactly what it has been designed to do, and it does it better than any other device on the market.

    A few reasons the Smart is Smarter:

    Most people will deactivate the auto locking function when paying out slack from a Gri-Gri. This is bad, but Gri-Gri users have found that it's the easiest way to make sure you don't short rope a leader.

    So what if that leader falls? - even an experienced climber may forget to let go causing the device to remain unlocked = climber fall. Hence many gyms have gone away from using Gri-Gris for the safety feature. The Gri-Gri is still great, and I have one, but I prefer to use a non-mechanical belay device.

    The Smart on the other hand REQUIRES conscious belaying. A user can't just assume the device will do its job and absent-mindedly watch the birds fly by. The belayer is actively paying out slack, taking it in, or otherwise performing their job. Paying out slack is 10x easier than the Gri-Gri, and therefore safer. The #1 reason I would use a Smart over a gri-gri is that you don't have to deactivate the auto-locking function to pay out slack. This is where the Gri-Gri fails.

    Oh, and the Smart is LIGHT - MUCH lighter than the auto-locking devices. Not only is it lighter, but it is simpler. This means there will never be a mechanical failure, there will never be a need to clean the gunk out of moving parts. Lastly, the Smart works down to an 8.9 rope - the Gri-Gri is only rated to 9.6.

    Why then does the Gri-Gri dominate the market for belay devices? Five letters. PETZL. It's a matter of recognition. The Gri-Gri has been around so long, and Petzl is such a great company that people have taken it for the standard. Well now there's a new standard for safe belaying - The Smart belay device by Mammut.
