You've just bought your brand new rope and you are extremely excited to pull it out and get some use out of it. You notice that it is bundled up in a nice tight little coil, and you think, "hey, this is perfect for my pack!" So you take it to the crag.
It's a beautiful day and you're itching to get on a route. You pull the plastic wraps off the coil, you release the initial wraps, and then...you drop the coils on the ground.
Now the whole coil looks like spaghetti, and you spend the next hour trying to untangle the mess.
It's certainly happened to me. And it's certainly happened to a lot of people I know. And if it hasn't happened to you, it certainly can...
When you uncoil a new rope, you have to be very careful. Essentially, you have to unspool the coil. The most ideal way to do this is with a partner. One person puts his arms inside the coil, while the other carefully unspools the rest onto the ground.
This can certainly be done by an individual, but you have to be much more careful.
Following is a video (unfortunately not in English) which shows a technique for uncoiling a new rope.
