Hello ML Vanquish owners,
Please try the following test on your Vanquish and report back on this thread your results...
I am getting unexpected results when I place a dime (silver or clad) on top of a nickel. The Vanquish returns a -4 or -5 (iron) in this configuration, regardless what mode the machine is in.
The same situation happens when I place a nickel on top of a dime or copper/zinc penny. Iron ID’s will also display when a dime is placed on top of a square tab. I’m certain there are other scenarios where two non-ferrous objects placed on top of each other will produce unexpected iron ID’s, without the presence of any ferrous targets nearby.....not a good result!
I’d love to hear back with any Vanquish owner the results of the above tests, but I’m certain now this problem affects all Vanquish owners, meaning there’s an issue with the software in the Vanquish machines that Minelab will need to fix.
I have a friend with a NOX 800 who says the above tests that produce negative ID’s on the Vanquish will produce unexpected Iron ID’s on his 800 “only” when setting iron bias to the max value of 9.
UPDATE:
I, as a few others have already done, have contacted Minelab support about this iron bias issue on the Vanquish machines. I’m awaiting a callback from ML to find out what they are going to do. A quick fix for them would be to provide a software update that would internally lower the “high” iron bias mode a couple levels from max so that non-ferrous targets with different conductivities stacked on top of each other (without any iron nearby) can continue to sound like a non-ferrous target. In the meantime, setting the Vanquish to “Low” iron bias after power up (540 owners only, unfortunately) is the quickest (no software update needed) fix, although a low iron bias setting will usually result in more iron sounding like a non-ferrous target...in other words more iron will be dug that would have been ignored otherwise.
Thanks,
