The ideal direction is with the shovel facing away from the direction of the pull. If facing in the direction of the pull, The sharp edges cut though the snow significantly reducing its holding power. The sharp edges of the shovel though the holes would cut a nylon cordette or sling - you would need to use a stainless wire or carabiners in the holes. You ...

Dry ropes and dry-core ropes are very similar. Basically they've been treated so they repel water (this does not make them water proof). "Wet" ropes have no treatment. What do these terms mean, and what are the conditions or types of climbing in which you would prefer one or the other? If you live anywhere where it rains and you plan to climb ...

What are the differences? The different ropes basically differ by how they have been treated to handle water: non-dry ropes (although I've never seen that mentioned explicitly) have no special treatment at all, dry ropes have only the sheath, treated with some water-repellant, while dry core ones also have a treatment for the core. In both latter cases, the ...

Consequently it absorbs the most water and thus getting heavier. Wet ropes also loose some of their dynamic properties, so falls will get harder. As it is the ...

Dry ropes have been impregnated with a fluoropolymer-based solution to prevent them from absorbing as much water as possible. Use of dry ropes is essential for alpine and ice ...

Do not use this cordelette for your protections: Knots will slip so the connection of the cordelette ends to form a ring will fail under load. Only use sewed Dyneema slings. Still Dyneema cordelettes are often used for climbing as they are much lighter for the same strength than nylon based ones. To know how this is possible despite the problem mentioned we ...

I thought that a sportsman has more red blood cells because his body needs more oxygen during peak performance. Working out uses up oxygen, and breathing hard is required to get more oxygen into your body. This demand for oxygen stimulates red blood cell production, and lowers the age of red blood cells. The result is that a sportsman has more oxygen ...
