Adds iron volume and some other stuff. https://www.minelab.com/usa/vanquish-software-update-1
VANQUISH 540 Iron Volume Control
Detecting in heavy iron trash is enhanced with the new Iron Volume Control feature. 10-step adjustments let you decrease the volume of iron all the way down to a whisper, while leaving desirable targets (non-ferrous) loud and clear. To engage Iron Volume Control, simply hold down the All Metal button, while simultaneously using the Volume buttons to adjust to your liking.
General Improvements for All VANQUISH Models
The upgrade also includes improved battery handling capability for all models, as well as a new low battery alert.
Anyone interested in a report on the 440 can find it here:
My hunting buddy Gary and I collaborated on the report for Kellyco and they published it on their website.
We found this a very impressive machine for $279 but you can read the report and judge for yourself.
Note: Gary and I are not employees of Kellyco nor do we have any financial interest in or relationship with Kellyco.

I read with wide eyed wonder a thread on another forum where it is stated that with the high Vanquish iron bias setting, or higher Equinox iron bias settings, that a dime stacked on a nickel returns a ferrous result. This has been called a bug, and some rather strident demands are being made that Minelab do something about it “or suffer the consequences.”
Iron bias is a variable filter, and the using it is a direct trade off. On an Equinox the F2 setting of 0 is as close to “off” as you can get. You will get nearly all non-ferrous and lots of ferrous will identify as non-ferrous. As you increase the control to maximum, less ferrous items will identify as non-ferrous, but more non-ferrous items will identify as ferrous.
It is a direct trade, one for the other. There is no free lunch. If you run iron bias at max, you will miss good items. Period. End of story. There is no fix. It’s not a bug. It is the way the filter works. Either leave it at its lowest setting, or accept that when you run it higher you will miss many non-ferrous items. Including nickels and dimes stacked together. Or get another detector.
Metal detectors do not know ferrous from non-ferrous. They know phase and eddy current decay. You can also filter on things like target consistency, etc. Iron bias is not a magic ferrous filter. It is looking at something, I’m not sure what exactly. However, ferrous items often give off multiple target id numbers in rapid succession, and this might be a consistency filter of some sort. It is not a ferrous/non-ferrous filter. Again, a detector does not see ferrous or non-ferrous.
Apparently a dime stacked on a nickel triggers this filter at a higher setting. I can understand how that might happen if it is a consistency filter. What I can’t understand is why that is a major freak out event. The manual says there is a cost to running high iron bias (see below). Anyone that knows anything at all about metal detector filters should know there are no free lunches. That’s why I always run all my filters as low as possible on all detectors I use. Did I know specifically about dimes stacked on nickels? No. Could I really care less? Not really. I do not think there are thousands, hundreds, or even dozens of dimes stacked on nickels that I am missing, even if I ran iron bias at max. But I do not. I always run it at 0 unless I use a default mode where there is some cranked in and forget to set it to zero. I run 50 tones and between the tones and high 39 spikes do not get fooled by ferrous enough to think I need employ the iron bias in any situation except perhaps a field full of flat tin steel.
I hunt gold nuggets a lot, and one thing that does is teach a person a lot about filters. All ferrous / non-ferrous filtering, no matter the type, with misidentify some gold as ferrous, especially in high mineral ground. I will never forget a gold nugget that I saw the Gold Bug 2 disc mode call ferrous in an air test. Or the .22 shell casing my F75 and Gold Bug Pro called ferrous sitting in plain view on top of some particular ground. Real eye openers. This also applies to any coins at depth, right at the point where they almost disappear. In most ground the signal will flip from non-ferrous to ferrous at extreme range. It’s how detectors work, and calling it all bugs just means a person does not know how a detector works. Or that all detectors have bugs, take your pick. I’ve actually written entire articles about it.
Some people have a high tolerance for digging trash to get good items others miss. Others really hate digging trash, and employ high filtering i.e. discrimination and other filters. They should know, or need to know, that if they are digging no trash, they are leaving good items in the ground. Every filter comes at a cost in this regard, some more, some less, but the only thing that insures missing no good targets is to use all metal and dig everything. Even then, the ground balance filter will leave good items in the ground.
Anyway, good luck to those expecting Minelab to publicly address the dime on nickel “bug” and good luck seeing it get fixed. In my opinion it is inherent in the filter and the way it works, and the way to avoid it is to run the filter at the lower settings. Or get another detector if you are a person that specifically hunts dimes stacked on nickels.
Equinox Manual, page 52 (emphasis added):
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.
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.
So I've been getting a lot of clad coins with both the Equinox and the Vanquish 440 in the local parks, but even in the older ones, silver coins have escaped me for a couple of months now. In between thunderstorms this afternoon, I hit the neighbor's parking strip, and in less than ten minutes, I pulled two silvers and a wheatie! My first silver quarter, AND my first Canadian silver. The quarter is pretty trashed, but I'm glad just the same!
Felt good to break the slump!
First time on the beach so it was a new experience for me. The Vanquish ran very quiet over the dry and wet sand. I was able to run the sensitivity maxed 99% of the time. No great finds but did get some deep and some small targets. I ran in the jewelry mode with 1 notched out. Couple opals found about 15ft. apart I'm sure they came from the same piece of jewelry. A sterling earring back along with another small silver(?) piece off something and a fake coin that I at least said hmmm when I first dug it Lol . Plenty of clad coins. I almost (almost) quite digging those 10 plus inch zinc signals but it was a good experience. Thanks for looking! Tom
