metal
detectors apparently date back to the shooting of us president james a.
Garfield in july 1881. One of the bullets aimed at the president lodged inside his body and couldn't be found. Telephone pioneer alexander graham bell promptly cobbled together an electromagnetic metal-locating device called an induction balance , based on an earlier invention by german physicist heinrich wilhelm dove. Although the bullet wasn't found and the president later died, bell's device did work correctly, and many people credit it as the very first electromagnetic metal locator. Artwork: left: find that bullet! this sketch by william a. Skinkle, from frank leslie's illustrated newspaper of august 20, 1881, shows rather a lot of doctors (!) using bell's induction balance to find the bullet lost in the president's body.
Thirteen-year-old milly hardwick was only on her third metal-detecting expedition when she made a thrilling discovery in 2021 in a field near royston, england. The high-pitched squeal of her detector was followed by giddy laughter when milly’s father dug up a hoard of bronze-age ax heads. The solid-bronze axes would have been some of the earliest metal weapons made in england as early as 2300 b. C. Milly and her father unearthed 65 objects that day , and a follow-up archeological expedition found a nearby hoard containing more than 135 objects.
By now, many casual readers of the metal detecting life have probably realized i also create my own metal detecting videos on my youtube channel, swing4thering , which is where i post most of my metal detecting adventures. I started making videos back in 2012 on youtube on another channel, ace yo , when all i had was a cell phone and did no post editing on a computer. It was just raw metal detecting and treasure hunting videos, along with a few other random happenings at the time . Fast forward to now where i record with multiple cameras, gopros, and even a drone! i take time to edit and piece together each hunt to help tell the story, as well as add in some music and sound effects or extra graphics for a little fun from time to time.
Beat frequency induction
There are several types. Three common ones are:
bfo or beat frequency oscillator. Entry-level detectors typically contain a bfo. It has a large coil in the search head and a smaller one in the control box. Each has a pulse oscillator but on slightly different frequencies.
The pulses generate radio waves to create audible tones. The tones change when a magnetic field interferes with them. They are also not as accurate or as controllable. Vlf detectors. These are quite popular and tend to be the most common. These very low frequency devices use a single frequency between 6 to 30 khz and rely on phase shifting between the transmitted and received signals.
