Pulse induction means that you are creating an electromagnetic pulse that exits the coil, bounces off a target, then returns to the coil giving a report on the target it hit. Pulse induction detectors are usually more sensitive to smaller and deeper targets.
UNDERSTANDING THE PI METAL DETECTOR BY REG SNIFF. One of the more popular metal detectors used for nugget hunting today is a type of detector commonly called the Pulse Induction .
A pulse induction (PI) metal detector can be very easily implemented with a single GreenPAK configurable mixedsignal IC ().Pulse induction designs have the advantage of tolerance to ground effects, and work even when submerged in water.
(PI) Pulse Induction Underwater Metal Detectors Transmitting electronic pulses to the ground PI underwater metal detectors are highly sensitive to coins, jewelry and relics but yet not affected by ground minerals or wet sand.

White's Surfmaster PI Dual Field Metal Detector with New 12" Search Coil. The White's Surfmaster PI Dual Field metal detector is the result of over fifteen years of research and development from one of the most outstanding manufacturers in the treasure hunting business.
World's First AllDigital Metal Detectors. VFLEX transforms conventional single frequency metal detection technology by including two microcontrollers (miniature computers), one inside the control box and one inside the coil.
PULSE INDUCTION METAL DETECTOR STINGER USER'S GUIDE MADE BY MIKRON BULGARIA 2006 . w w w . m d e t e c t o r s . c o m 2 a "STINGER" is an impulse metal detector with an LCD – Display, digital and graphical presentation of the level of signal and parameters of discrimination and working modes, as
When you're looking at purchasing a metal detector, you're going to notice right off the bat that you need to decide between a pulse induction metal detector and a very low frequency, or VLF, metal detector.
Operation of a VLF metal detector Pulse Induction Detectors Pulse Induction detectors work much like SONAR on a submarine. Electric current is sent in microsecond long pulses through a coil of wire that causes a brief magnetic field to be induced.
Apr 26, 2013· Page 3 Pulse Induction MD Beach and Water Hunting List all sponsors : Friendly Metal Detecting Forums > Metal Detecting > Beach and ... Metal detecting is NOT rocket science, it's a hobby. In the 35+ years I have been detecting and instructing, I have run into a lot of blowhards that think they are better than the next guy, or have better ...
So a couple of years ago I started a project to build my own pi metal detector. I bought a silverdog surf pi kit and had every intention to complete it! Well unfortunately my soldering and electrical skills back the. Were near non existent and so the project got stuffed into a box and forgotten ...
The idea is to use the Arduino as a Pulse Induction detector, like in TPIMD, as the timing idea of the decay curve seems to work pretty well. The problem with Pulse Induction detectors is, that they normally need to different voltage to work.
A metal detector is a gadget that detects present of metals in the ground. There are mainly two types of metal detectors, the Pulse induction detectors and Very low frequency detectors.
The Scuba Tector, with Pulse Induction Technology. No falsing in saltwater and black sand environment. 95kHz Frequency. Order online in Cape Town, South Africa. Freshwater or Saltwater conditions with up to 60m depth. The Scuba Tector, with Pulse Induction Technology. ... Makro Kruzer™ Beach Metal Detector Fisher™ FPulse Waterproof Pinpointer.
Nov 23, 2011· The pulse induction detector sends out a short pulses into the ground, thereby magnetizing any metals. The induced current inside the metal is measured by the same coil which sends out the pulse. Mark: your explanation of the diagram sounds right to me.
This is one of the best deep search machines on the market with metal discrimination. It was design specifically for professional Treasure Hunters in country where first metal detector .
The Surfmaster uses pulse induction technology, which will generally detect deeper than VLF (very low frequency) detectors. The headphones are waterproof, but be warned: Even with adjustable volume, some people get headaches from the beeping, especially on prolonged hunts.
This is true for all pulse induction metal detectors. Because of the low conductivity, the eddy currents have disipated by the time the pulse delay has ended and you begin to sample the signal. The lower the conductivity of the metal, the faster the eddy currents disipate.
Mirage PI Pulse Induction project for small gold and gold jewelry items. Excellent for coin hunting, beach and water hunting as well. Custom built or build your own metal detector.
