These sensitive metal detectors locate nails, screws, staples and other metal objects concealed in wood, plaster, plastics, etc.
The small detector projects a 3" detection swath and locates objects up to 1" deep* with a high-pitched tone/LED combination alarm. The large detector is used in a sweeping motion and projects a 5" band effective up to 6" deep*.
Toggle buttons switch the detection signal from a combination high-pitched tone/LED to a vibration/LED combination for use in noisy shop environments. Ideal for people working with salvaged lumber, both are excellent methods of detecting screws or nails that could cause costly damage to hand and power tools.
Each requires a 9-volt battery (not included).
*Depth of detection depends on size of material.
The Large Metal Detector is no longer available.
