" Halo Effect"

I ve been lookin in the mirror and cant see no halo. Do you have to be holdin your detector or somethin. Wife said somthin bout horns but I dont see them either.
John
 
Ever detect a rust pocket Willy, dig and find nothing, and get no further signal over the hole or the pile of dirt. That's the halo effect. And being unable to detect freshly buried coins is due to an effect known as "Metallurgical Phenomenon" Just some of the mysteries of detecting.

Bill.
 
THe type of soil an object in has an distinct effect on the halo, it's size, and conductivity. HIghly acidic soils leach more particles from the object into the soil surrounding it creating a thicker and bigger halo. Just simple physics. Some metals leach easier than others.

Bill
 
Moisture increases the conductivity. Like standing on a wet floor and sticking yoiur finger in an electrical socket.

I'll tell you something else that produces phantom signals and I've had it happen to me more than once. If you're hunting in grass or a weedy area and you get a signal that produces no target when dug - check in the grass around the hole a few inches out and you'll often find the target there laying at the base of the grass. The edge of your coil picks it up but signals as if it's right under the coil. I've found several coins like that.

Bill
 
but what many other people are talking about is a halo effect around copper/silver/gold/nickel and such. Maybe some of those new clad coins that seem to disintegrate 3 minutes after hitting the ground, but not the other stuff. It would have to be some nasty chemically reactive ground to cause an appreciable amount of metal to leach away. As for not being able to detect freshly buried coins, I've never had that happen to me (but then, how would I know, 'cause it would be negative evidence). I routinely bury objects (often rather deeply) just to see how the signal sounds (in that particular patch of ground) and haven't had any trouble; can it get any more 'freshly buried'? ..Willy.
 
Before investing in a sunray X-1 probe....I have dug many targets that just disappeared, I read about digging a little further and yes.....Viola...some where found........ cause of disturbing the ground and it would disappear and coil could not see it anymore. But there were also times it never got recovered and I dug another foot deeper...talk about waisting my time!!.....Then I bought the probe and wahla!...I found targets off to the sides of the holes shooting the signals sideway......good example is the shot gun shell.....or a coin on edge.....with the probe I could tell it was afew inches or so to the left or right of the hole.......BUY A PROBE!!!!!!!!!!!!!!!!!........end of my frustration!!!:beers:
 
r.r., yeah I've been thinking that I need to get a probe for my MXT as it doesn't seem to pinpoint as well as the Tesoro I have (or at least I can't get it to pinpoint as well). Are you saying that once you start digging the hole, if the target doesn't show up, the DX-1 pinpointer is good at locating it along the edges? Or, are you using it over the area where you've pinpointed, before you dig?

TIA
 
Both......I have a certain pride on how well I can pinpoint....and dig small diam. holes and have it in the center of hole........but what slipped right past me was those targets shooting a signal sideways......also I have dug holes and disturbed the matrax of the dirt and lost the signal.....and have found it with pinpointer just a bit deeper....To a newbie just starting out, one will tend to dig say a 4-6inch hole and find nothing..pass coil over hole again and get no signal.....so he tends to just think of it as a ghost signal.....and buries the hole......but after reading on a forum to just take a few more scoops out of hole and he starts to relize how much he has missed...but there are still times he digs a little deeper or alot deeper and still nothing......a few get past him......then he goes and buys a probe and relizes the few that got past him was off to the sides by 2 or 3 inches cause of the way it was facing in the dirt.....so far nothing gets past me unless I need a back hoe.....:stars:
 
Wow, never experienced a signal that I could identify as coming off sideways, but I don't doubt its possible. Really appreciate your input on the in-line probe/pinpointer. Makes me think that the signal coming off a White's 9.5 is different somehow than the one coming off a Tesoro.
 
I new a man that said: " Gold will move in the ground when you try to dig it. It's best to have two people and both dig at the same time so the gold doesn't have any where to go."

The old, Afro-American gentleman wanted me to help him find a gold cash. He said I would have to dress with gloves and a hat so that locals couldn't tell I was Caucasian.

I didn't have a detector at the time. I never took him up on it.

He was the superintendent of a sewer commission. I worked for the engineering firm that supervised the construction of the treatment plant and sewer system.

I often think about the old man. He has passed away and I never got to find out where the cash was supposed to be buried.

HH,
 
however you do take a chance on nicking a good'un on occasion. In that case I can see a probe being handy.
