I don't have my NOX 800 anymore to test this, but can someone take a small gold chain and a piece of wire for a test? I want to see "iron bias" used to ignore the piece of iron and sound off on the small gold chain. That would be not just discriminating.
That would be interesting.
Although for a small gold chain, using a high single SF, or a low conductor weighted SMF, will likely be important.
Sorry Detector, I read through your post too quickly, and didn't realize that you were still (mistaking ) iron bias with iron discrimination.
Iron bias needs opposing data points to work. If there are no opposing data points, then iron bias can't be "biased" to one data point or another, because only one data point exists in your example.
In your example, the gold chain reading as iron 4, will be exactly the same to the detector as the iron wire reading as iron 4. There is nothing for the detector to be biased toward, or against. In other words, iron bias is irrelevant, and doesn't apply in your example.
That makes it a little clearer AirmetTango, thanks….
Cool, glad it helped out Detector! Iron bias (or Iron Filter) isn’t an intuitive setting, and the feature has several nuances that definitely takes time and practice to wrap your head around. Heck, I enjoyed reading the thread, thinking about the questions, doing the video, and the write up because it helped me to solidify my own understanding of iron bias and how to explain it.
But we hear that IB only works on a SMF unit and especially with a "more weighted" higher frequency, not a SF. Really? How about two or three models I have been using since June of '94 that have an adjustment function to help classify a problem ferrous target, the annoying Bottle Cap? AND it is Single Frequency AND a lower Frequency!
So to answer your original question, I believe Iron Bias is only available in multi on the Equinox while Silencer is available in all modes on the Deus 2 because the two features are apples and oranges.
For those that want the best way to sniff out the coins from iron, then an iron bias control is a critical component for doing so. However, choosing the correct frequency, or frequency range, is also very important. You would want to use an SMF that is weighted toward the high frequencies...
Could shape of iron ( not associated with bottle cap behavior) drive Equinox’s behavior using either FE or F2 iron bias?
I can’t say anything more right now. NDA
Large pure ferrous objects can create a non-ferrous response as well (also specifically mentioned on the same Equinox manual page)
