edge finder

Edge finders are the most basic internal capacitor detectors.

In contrast to the edge finder, the tip is not spring-loaded and it works with the spindle stopped.

Most accurate of all edge finders.

The single sensor in edge finders can be prone to error, sometimes indicating a spot an inch or more from the stud's edge.

Like edge finders, center finders require calibration.

The light is thus illuminated when the edge finder is touching the workpiece and is visible through openings in the case.

Sometimes also (erroneously) referred as a digital edge finder, this instrument can locate edges of work pieces and also height offsets.

Electronic stud finders currently come in three types: edge finders, center finders, and instant finders.

A New Edge Finder Tool that allows edges and contours to be extracted from images for precise gauging and measurement.

On one edge a cylinder shape is spring-loaded, when the edge finder touches an edge a kickoff of this cylinder is noticed.

Because the instant stud finders use multiple readings to determine the location of studs they are less vulnerable to construction anomalies (such as uneven paint, wall textures, wallpaper, uneven plaster, etc.) that can disorient center and edge finders.

It is also worth mentioning that when the MythBusters were designing a fan with the goal of chopping off someone's head, Scottie used an edge finder to find the exact center of their blades with the aim of eliminating potentially very dangerous wobbling of their steel blades.
