Target seperation

[Germs73]

This may sound stupid but I'll ask anyway...when they say a coil has great target seperation what exactly does that mean?? Does it mean it it separates iron and other metals better?

Germs 73,
I'm gonna take a stab at ur question here... I believe it is in reference to the coils ability to isolate or well ok, separate one target from another but also when you have several targets very close to one another..good targets can get "masked" by a few bad targets very close by... Some coils do better than others..but i think the key here is multiple targets close together.

Typically it could compare size and construction, performance of a particular. Coil or coils. Looking at this another way.if I hear a ...sort of good target but a couple of pinpoints with in the same area and i step 90 degrees around the thing and sweep the same target..that's essentially. What i'm doing, trying to separate the good target from the bad etc. But again, this is talking bout the coil itself s ability to do that...
..Hope that helps ?

It means the coil can pick out a good target in close proximity to a junk target. An example would be metal detecting in someones yard which is littered with nails. A large coil would have difficulty picking out a silver coin amongst all that trash because the large coil sees too many targets under it at any given time. A smaller coil has a much smaller footprint, allowing it to pick out a silver coin.

Thanks a lot guys...it makes a little more sense now...
