Learn more about your detector with a cardboard box

Cut long slits spaced 1 inch apart. Stick a coin in a slit to test signal strength at any depth. Add a piece of trash in another slit and see if your detector still reacts to the coin. Sweep the coil almost touching the box top. Picture shows a quarter and a tab.

When get out of this place(at work on a Saturday) I'm gonna try that when I get home. That's a great idea.

Good way to get a handle on air depth and masking both.

Jabbo what is that green coil in the background???

8x9 Tesoro coil sprayed green. It was New Years eve and seemed like a good idea!!

nice idea...will help ...

You could fill the box with local soil. You'd then have some mineralization over half your loop.

Ingenious idea, Jabbo. Good job!

What a great idea!!!

Glad you guys like it. Added 2 shelves to hold any trash that won't fit in the slits. Made from stiff cardboard with a block of wood glued to the bottom so that it stays level. Also added vertical lines spaced 1 inch apart so I can tell how close the trash is. Been using it over the weekend to compare different coils and to see if I can tell when a coin is near rusty junk.

Every Dealer Should Have One....To demo machines instead of the "Target Strips" That Whites makes!!!!!!

The only reason I can see why you would do this is to collect air test figures for a new machine to you can return to every few months to see if the machine or coil is drifting off tune.

If used to compare two different detectors one might be an inch deeper on a target but directly you get out on to real ground the lesser performing machine may well prove to be the deeper one.
This is especially true of target I.D. Many of the best in air perform the worse in ground. Then BBS/FBS machines have to be considered that require some degree of mineralisation for the best results.

That is a great idea. Proof is in the pudding.

Great idea! What depth are you all getting and with what brand and model? I have the BH Quick Silver and played with this, I got about 5 inches with penny and nickel but quarter got 6 inches.
