Profile: Tesoro Electronics, Inc. is a manufacturer of metal detectors and coils. Our product line includes detectors, coils, and other accessories. Our DeLen is a Target Identification Detector or T.I.D. The DeLen is designed as a turn-on-and-go detector. The faceplate has only four controls: Sensitivity, Discriminate, Threshold, and a Mode Switch. It uses the same circuitry as the Corts. The DeLen display screen is one character high, by eight characters wide. It is larger and easier to read than the Corts display, but does not carry as much information.
