OK here's the scoop on the Pulse Devil. There are actually two different designs. The first version is a PIB or Pulse Induction Balance. This version requires a balanced coil such as a coaxial or a dual D. It does however have a full range of discrimination. The PIB was invented over twenty years ago by Eric foster. Eric sold a detector called the PPD1. The Pulse Devil PIB takes advantage of various techniques I have developed which provide excellent depth, ground canceling, and discrimination. It is possible using these techniques to incorporate a target ID and even a notch filter. The Pulse Devil PIB uses a push button tuning system as well as motion circuitry.
The second design is the Pulse Devil Mono Coil Discriminator. As its name implies the detector is capable of working with a single winding coil. The mono disc has good iron rejection except on steel crown bottle caps and some very small objects. Overall the iron ID seems to be good to excellent.
The mono disc provides different tones which identify four different target groups. These are low, medium and high conductivity targets and of course iron. Examples of low conductivity items are a US 5C piece, (nickel) thin rings, and small gold nuggets. Medium conductivity items include copper coins, bronze coins, and clad coins. High conductivity items would include silver bars and coins, and of course aluminum beer cans.
OK, now we know what the pulse Devils are I guess you are all wondering if they are ever going to hit the market. The Pulse Devil project is now about three years old. It is very tough when one works a day job to get enough time to finish anything. To make things worse, I came up with the idea for the mono disc method and went off on a tangent from the PIB to see if it would work.
As it costs ten to fifteen thousand dollars to obtain just a US patent and tens of thousands for world wide patent protection I have decided to put the technology into the public domain. By describing how the mono disc works in a technical magazine article NOBODY can ever patent it.
The first prototypes are about ready to go. Eric Foster will be testing, improving, and if he feels the design is OK, will I imagine be building and selling them most likely with a new name. My thanks go to Eric Foster and also to Mark Pauls in Denmark for their substantial input on both designs.
