The Iron Eliminator is not a chip, its an external device not attached to the machine in any way. It allows a coin for instance to be picked up from among a handful of nails which the machine normally would not pick up....and it does work.
Again as its metal detecting there's no free lunch, there's drawbacks.
First what is it. Looks like a test tube full of aluminum filings. One variety had an iron nail wrapped with copper wire. No batteries.
The way it worked was my fooling the ground balance of the Spectrum or XLT. Air balance as normal then ground balance but to the tube. This would be held above the coil and the angle it was held at to the coil set the amount of iron rejection you would get ie 25% or 50%.
The detector also had to have a custom programme installed. This switched off ground tracking for instance (as the machine had to remain balanced to the content of the test tube).
You could then happily search amongst iron contamination that your detector would not normally deal with.
Problems. Ground balance was set to the tube, not to actual ground conditions so normal depths could not be obtained and machine became incredibly 'liffty' (an old pre motion detector term) if you lifted the coil only slightly as you swept it the machine would sound off fit to wake the dead.
So an idea that works but not that well. Far better to buy an old IB/TR detector running at 100 khz.

Here's the link to a patent for one of these devices. it's patent US 5247257. I think it is a rip off. I could do the same thing by using a several nails, ground balancing and then locking my ground tracking. Rob

It is just a device to ground balance your detector to an "iron rich" target and then locking the ground balance.
Your detector will now not react to the iron rich ground, but (there is always a but), you'll lose depth because the detector is way off real ground balance and prone to be noisy because the ground balance is so far off.
