halo effect

[greasecarguy]

Did u ever notice that next to every bad signal, there's a potential good one? How many times have you heard what could be a nice deep, good tone only to discover it was the halo effect coming from a piece of junk nearby? The only way I know to discover this (besides digging) is to pinpoint over the good one to determine if there's something there or not. Usually the pinpoint sounds good but is drawn to the bad target, telling me this is what I am hearing.

The question is, does anyone know how to determine whether or not there is a good target next to a bad one?

thanks for the help....

I dont know, but I do know I used to decide whether to dig using this method, and then realized there actually was a good target next to the bad one about half the time. Now I focus on repeatabillity.

Use the ML wiggle and like Bell said i try to get a repeatable signal or a tone that just doesnt sound like iron bounce or wont go away. I dont know about it being HALO as much as that darn rust. Rust on a target.... like a round bolt or bent nail will give you that sweet repeatable tone when they are deep. There isnt but one way certain to check those.. and you need to check them ... thats dig. Because of wrap around caused by too much sensitivity to a target based on size, averaging, depth and your disc.....the processor does its best, but you have to decide when to dig. Some times you just have to take the screen out of the equation except for the depth and take a stab at it. I think sometimes people see a spot and try to cover too much ground in a trip. Be content to pick a smaller portion gird it out and work it carefully.... personally i think that puts more coins in your pouch than doing say a whole park in a day and calling it worked out. Like it or not we need to find more reasons to dig... not more reasons not to dig especially us unseasoned people. Theres not greater excitement that digging down say 8 inches and nothing.... but the SE is still telling me its there bud its there.... then finding it finely on the side of the hole. It will tell ya what you need to know just listen to it.

Hey, I always heard it was the "edge" of the iron that gave the good signal. Really doesn't matter, but it is sure a pain. GCG, you mentioned my first tip off that it is iron and that is a good signal walking you over to a null. Do the tiny 3 inch sweep, turn 90 deg. do it again, if you get a good signal both ways you have something. If you only get a partial good signal once turning 90 deg. your odds of a goody drop to around 50% If you get a null at 90 deg it is most likely iron. After that if you want, pinpoint the exact spot where it sounded good, without moving the coil forward or backward do the tiny sweep again. If it sounds good go for it. If it nulls, you are being told something. With that said, you also sometimes get a signal that just sounds too coiny to pass up (even though it nulls at 90), screw all this stuff and dig the thing!

One thing you can do is put on ferrous tones with no discrimination. This may give you a better idea if there are in fact two targets down there.
