Not really impressed with it.
It will show iron as high tones, most other frequency choices it can an might do it too but this one really keys in on that stuff.
Another issue is if you turn on the horseshoe to go to "all metal", most of the time it won't report back with any low tones of numbers at all.
This happened to me all day yesterday, over high tone targets that were iron it was still a bit too jumpy vs good targets like coins so that is a good clue but over actual iron, and I mean from tiny pieces up through larger ones, it still gave only the high report.
On several I switched to 5kHz and the high tone was still there but the low tones and iron numbers came back and were peppered in there also and as I switched to every frequency up the line the same thing happened.
On more than one occasion that high tone, high number only signal with no iron indications turned into an iron only signal when switch over to multi... true and accurate information because I didn't just assume but dug many of these just to be sure.
This makes it useless to hunt with in my sites because we have an unusual amount of iron infestation around here.
Also it not only fails to report on iron but if you are expecting to notice any low conductors you can forget that...it won't see much below zinc which isn't a problem for those only looking for high tone old coins and silver but for jewelry hunters it abysmal.
I realize that low conductors like nickels can be changed to high tones and you can still get them according to a few others but in my dirt I didn't see this at all...low conductors seemed to be invisible but with my mineralization and massive iron issues in my devil dirt this could be my cross to bear and in better dirt not so much.
Many times I have gone hunting to find old silver coins but found a low conductors gold ring instead because when I hunt using any detector I use a pretty wide open range with low disc because you never know what you might come across out there.
If you hunt only in 4 around here you will negate that possibility, horseshoe turned off or on.
The update did seem to quiet it down some in some heavy EMI situations, maybe make for a more stable environment overall but this is only a feeling and I need more hours to gather more information on that.
It has been reported it could mess with your pinpoint accuracy...I rarely pay attention to the bars or look at the numbers when pinpointing so I don't know about that.
In good soil with less iron it might work pretty well as a hunting profile and I am sure over actual deep silver it will do what it is supposed to do as advertised...hit it stable and clear with great tones and very little noise or chatter and I can see me using it as a check for when I find some high tone targets especially deep ones but using it to hunt with compared to multi...never going to happen for me.
