This entry is about pre-equalized anchors. The Canadian guide, Mike Barter has put together a variety of videos on youtube that are valuable to both the novice and the advanced climber alike. Following are three of his videos on pre-equalization. The first two are for novice anchor builders, and the third is for all those looking for a short-cut.

There is a little bit of controversy over pre-equalized anchors. Some feel that one leg of the anchor will get more force than another, which means that such an anchor could never be fully equalized. While there may be some truth to this concern, the impact on the anchor as a whole is minimal and professional climbing guides throughout the country are generally not concerned about it.
In this first video, Mike describes a sliding-x, followed by the basics of pre-equalization.
The following video takes what Mike just described to the next step. In this video he demonstrates a pre-equalized anchor off three pieces.
Speaking of building an anchor with only a small number of pieces, more advanced climbers that already have a strong understanding of their anchoring skills may find this next video a bit more valuable.
In this video, the guide provides a quick tip for keeping the power point high.
Practice makes perfect in every one of these techniques. So keep on practicing!
