These are fun and unusually sensitive but I think the greatest thing it can do, and the reason everyone should have one in the arsenal if only used sparingly, is what it can find close to big metal.
Swing at the right speed and it will double beep on all targets near, next to or even actually leaning on tot lot iron, bench legs or fence poles.
Triple beep if it is shallow.
This vid shows it, I should have moved that dime all the way but I assure you I could have literally leaned this dime onto and touching this post and it will still do this because I have found many coins in tot lots that were exactly that way.
Even a Canadian Looney once 4" deep in the chips.
I even swung under a thick metal step that was maybe 3" above the chips and it double beeped on a coin lying directly under the middle.
You have to experience this to believe it.
I have never replicated this using many other detectors, coils and every setting I could think of, not even close.
For the Compadre this task is effortless, a little superpower this thing possesses that is like no other detector I have ever used.
