Iron Bias number

What do you keep your iron bias number at? I have the 600 and I don't really know about this feature as I am still learning it. So far I have it at 2 is this ok?

Iron Bias two is the default number for Park 1 and Beach 1 and 2. That is said to be equal to Iron Bias 4 on the 800

So that is a good starting point. The higher you set Iron Bias you can start missing desirable targets.

Park 2 and Field 1 and 2 use 0 IB

For some reason the 800 uses slightly higher Iron Bias numbers which will tend to ignore more items with low percentage Iron Content - see page 52 of the manual.

Most desirable metals have a percentage of Iron readings. An example would be on my Explorer. A Dime reads 3/27 under ideal conditions. 3 is the iron number.

That is what I understand from reading all the information.

Thank you for the info I'll put this to use.

2 is pretty high. You will lose sensitivity on good targets. Try it in an air test.

I would only use iron bias in a highly contaminated iron site. And I don't mean "has a lot of nails", I mean a lot of nails (or tin can shards) very close to each other (one every inch...)

In a "normal" environment (whatever that is, I consider a school or park to be the norm), using iron bias may be a bad thing. Try using it without, when you get an iffy target, try some IB setting and see the difference.

I'll put it back to 0 then. Thanks

From the Manual

All ferrous targets produce a combination of a ferrous and nonferrous
response. Large ferrous targets can even present a stronger
non-ferrous response. Also, a ferrous target adjacent to a nonferrous
target can produce a similar response.
The Iron Bias Setting provides some control over the Target ID
response. A lower Iron Bias setting will allow the natural response
to dominate which means that the target is more likely to be
classified as a non-ferrous target. A higher setting will increase the
likelihood that the target is classified as iron.
The Iron Bias setting has a range from 0 to 9.
Iron Bias is only available when the operating frequency is Multi.
Iron Bias adjustment is local; only the current Detect Mode
Search Profile will be affected by changes to this Advanced
Setting.

In environments with dense iron trash, a higher Iron Bias is
recommended in order to mask them.

In areas where you do not
want to miss any non-ferrous targets amongst iron trash, a lower
setting is recommended. This will cause more ferrous targets to be
detected and identified as desirable non-ferrous targets.

Either way you go there is some give and take

Shows there is much improvement to be made in detectors.

If someone can come out with a detector that doesn't tell you there "some" iron in a (copper) penny, they'll have something!
