I would recommend a simpler tool or better scriber. Vernier scales are wrong and practically useless. The scale measures up to ten inches, but only 8 can be used. You need to mark with a pen or pencil, so marking errors still need to be accounted for. Wen has a manual on how to use this device, but it's immediately obvious that the increments are wrong and they don't really instruct how to use it. So if you don't know what to look for, it's easy to miss.
