    Abstract: An orienting system for precisely aligning downhole tools with respect to each other, such as perforating guns, exploration tools, or other completions tools. The orienting system provides for orienting a first tool with respect to a second tool in a predetermined number of degrees of rotation, and then locking down the combination for use downhole in that configuration.
