Hi Doug,
I think it could be a lot of fun too.
But I am not convinced that it will detect metals from long range.
Yet I hear stories that people find long range treasures using metal detecting locators adapted into a pistol design.
I would like to see some real testing to see if this design can recover hidden treasures or not instead of stories.
But until that time, it could be fun to build and to play with.
Remember, this is not simply a hobbyist design.
It was designed by a electronic engineer who included many features that hobbyists generally ignore.
Thousands of these locators were sold commercially more than 40 years ago.
Of course, it is an antique circuit by today's standards.
IB locating with an omega shaped coil is not very common today because it was largely replaced by pulse induction and VLF double-D methods.
But this design is still highly sought after by LRL experimenters because of the amazing ability to detect tiny signals that no modern detector can detect.
When hobbyists cannot buy the few remaining original factory versions of this locator, they can still build their own copy exactly as the factory design specifications for less than $30 parts.
Now the process is easier, because the complete circuit diagram is shown here with nothing missing, along with details for adapting it to a pistol detector design.
Best wishes,
