The objective of the GoldPic 3 project is to detect coins and jewelry in shallow water and on the beach by optimizing the timing and circuitry for detecting small items. Using readily obtainable low ...

There are several applications in which pulses longer than the set width are to be detected, ignoring the other short pulses. We are familiar with the missing pulse detector circuit, which detects the ...

With a 200 foot depth rated housing and a 6 foot maximum detection range, the Pulse 8X from JW Fishers is the company's top of the line detector. It's heavy duty construction and high sensitivity make ...

A metal detector used to be an entirely analogue instrument, an oscillator whose frequency changed with the inductance of its sense coil when a piece of metal approached. [Łukasz Podkalicki] shows us ...
