What is the advantage of "Overload Alert" on Delta?

[jordanls78]

What is the advantage of having an "Overload Alert" on the Delta 4000? What is an overload on a metal detector anyway? How would you go about preventing an overload?

I'm trying to learn as much about the Teknetics Delta 4000 as I can before I actually purchase it.

Thank you for any info that you can provide,
Jordan

alerts you to either a larger coin, such as a silver dollar, or some larger-size metal target, such as a soda can, sprinkler head, axe head, or other larger-than-coin sized target. You the the Overload Alert when the bigger-size metal is close, or too close, to the search coil. What it lets you know is that you probably have located a target larger than a desired coin or button or ring. You can just raise the search coil about 2"-3" and re-sweep the target. If it still produces an overload then you really have a big piece or (probable) junk.

In short, it is simply an added audio response alert to likely trash.

I preserve large Colonial iron relics via electrolisis, and also look for trash pits that always have large pieces of metal in them like barrel hoops, cast iron kettle pieces, etc. So, often after I'm done plucking out all the "small stuff" like coins & buttons at a site, I will go around & dig out all the "overloads". I accomplish 2 things by doing this. Moving the larger "overload" targets out of the way often lets you "unmask" some smaller nearby goodies like a coin missed. Plus, as I said, diggin overloads can also lead to finding a nice axehead or even a cache. So, people skipping all the overloads are often leaving behind some goodies like this Colonial axe for me.....thank you very much
