BacksightLimits

You can limit the list to items to situations where the fore- and back-sight difference exceeds a certain value. For example, you can limit the list to shots where difference between fore and back compass values exceed 2 degrees.  This is very useful for zeroing in on shots or surveys that need to be resurveyed. It is also useful for finding transcription errors.
