Compadre Depth?

[Beale]

Ok I got a new Compadre and I am not getting much depth outta it? Air test on a quarter aroun 4" is this normal? Just wondering, Beale.

I'm not much on air tests, since the halo effect in the ground can't be duplicated it the air. You should find quarters closer to 6" with the 5.75" coil.

It should do a little better than that in the air. Are you checking it in an area free of EMF, that can make a difference. Except under very unusual conditions a vlf detector will not detect any deeper in the ground than it does in the air on non ferrous targets, Most of the time it is less. There is almost always some loss of depth due to mineralization in the ground..
"Halo effect" has been proven to be nonsense on non ferrous metals.

I will try it again in an open area. I like using it it tot lots, very easy hunter, Beale.

I didn't know the halo effect was nonsense. Sure sounded good though.

Beale,
The Compadre I have acts up in the house while every other detector is OK as long I am not near the floor or a chair with the coil.

I can not even attempt to air test the Compadre until I take it outside.

I don't have the same coil as you, but 4 inches on a quarter sounds a bit low. I'm sure you already checked the discriminator, but make sure it is set low, like at iron.

I assure you it isn't nonsense. The "physics equations" may say it's not there-but it is. I found a silver dollar at 12" with an AH pro. The detector would just barely pick it up at half the distance in air, with the threshold (tr/vlf detector) at max. I also lifted the coil about 4" and still got the signal. I was expecting a beer can and put a gash in the coin.

Hi Hightone !

I assume you were just making a funny, but if not, AUDuke's comment " "Halo effect" has been proven to be nonsense on non ferrous metals." was specific to non-ferrous metals or precious metals like gold and silver that are resistant to sharing their molecules with the soil and as such do not generally form a halo. This is in contrast with iron and other lower grade metals that do leach into the surrounding soil, forming a halo, which causes a metal detector to perceive a larger-than-actual target.

Just trying to be helpful if you can use it.

Beale - The strength of the Compadre obviously isn't depth, but I think if all you're getting is 4" on a quarter there's an issue with the unit.

I'll airtest mine in the next day or two and let you know.

Hi AUDuke !

At the present time I'm not biased pro or con on the subject of non-ferrous coins (gold or silver for example) forming a halo after being buried in the soil for a sufficient number of years. In other words, I have an open mind, ready to form an opinion, but need credible evidence backed by good testing.

So, with the above preface, can you advise me where or how you obtained the knowledge that " "Halo effect" has been proven to be nonsense on non ferrous metals." ?

Thanks for the help !

thats normal i tested it 4 inches is about it but if you turn your disc back you get better depth and in ground whith disq up to foil you will lose depth but it will nails anything to 3" strong and 4" faint signal thats normal if you want depth you need a minelabe or at leasst a vaquero

Hi

Got a Compadre with the 8" hard wired coil.

It airtests 9" on our larger coins (euros), and deepest found so far was a two euro coin at something like 7".

Great detector for coinshooting in the dry sand !
