Review on Scriber Adjustable Locator Working Drilling by Shane Picot

Pros: Pretty versatile. Good quality parts. Good if you mainly want to mark the center lines on the edges. Cons: The fixture is not attached to the workpiece, making it difficult to achieve reproducible results. The locking rings for the attachments are too short, so they twist easily when tightening the set screw. This makes it difficult to drill holes to a certain depth. Comes with one set of marker pins only, so you need to drill each hole separately.
