Why B&D Leashes are Superior to Other Solutions.

Short Leashes and Peak Forces

In order for a leash to be more than a fashion statement, the leash must be sufficiently strong enough survive the force of a fall. The amount of force on a boot (and therefore on the leash) peaks at the moment when the boot releases from the binding. The violent shock of a boot exiting a binding generates a surprisingly large amount of energy. Years ago I personally broke a short leash comprised of 125 lb test shock cord. This is why most short leashes are steel cables. Steel cables are required to overcome the initial loads with a short leash.

Why Have a Fuse Link?

Simply put there are times when you want the leash to break. One time it is important that the leash release is during a slide. During a slide your skis may pull you deeper under the snow. Our fuse link is designed to break at a relatively low load when under constant pressure. This is the type of force you are likely to experience if your skis are sucking you deeper into an avalanche. Short steel cables that are strong enough to survive the initial fall will be much more difficult to break away from during a slide.

Long Leashes Reduce Leash Load

A ski leash must withstand both the static/dynamic force of the skier, and the static/dynamic force of the ski. A long leash allows the static/dynamic force of the skier to be absorbed by the snow. After the skier impacts the snow the ski leash only has to withstand the static/dynamic force of the ski. Short leashes have to withstand up to the full static/dynamic force of the skier since the leash is fully loaded before the skier hits the ground. The average skier weighs about 150 lbs, and the average ski weighs about 5 lbs. This means by eliminating the force of the skier on the leash we can reduce the load on the system by over 95%.

A Quick Word About Brakes

I always smile when I hear people talking about the superiority of ski brakes. It never fails that a person will launch into a story about how they spent a long time searching for a ski right after telling me why brakes are better. The simple truth is leashes reduce the time that you will spend chasing your skis or searching for a ski hiding in the snow.
