After a brief encounter with a Mental Detector, I came to my senses and got Vanquish 440. Trying to learn what it does, I think I figured out what the actual correlation between the target ID values, notch segments display, and the audio tones is. Perhaps it could be useful to others:
The target ID scale on this detector is non-linear, with the middle range between 0 and 20 stretched and both ends compressed.
The break points between tones, except for one case of Low-Med in Jewelry Mode, do not correspond to break-points between notch segments.
The yellow values, below the target identification guide graphics, represent the standard response (+/-1) for modern (Rama IX/X, 2008+) Thai Baht coins, when the target is strong.
I started thinking about buying Minelab Vanquish 440. The closest distributor from Bangkok (according to the Minelab website) is in Kuala Lumpur - that's a different country. It looks like it is possible bo buy this detector in Thailand from online sellers - but I really don't know who they are. Is that a good idea to use the online sellers? If not, how do I do that from Thailand?

Back at it again today,
But this time, I had a definite goal in mind! To intentionally try to squeeze out a few more old coins! And, oh yeah, to get rid of my now sore "detector legs" from Friday's somewhat short hunt!
A little side note question first! Am I the only one getting sore legs; and other parts, when digging a bunch of targets at the beginning of a season, or long hunt?? Or are the rest of you just too "afraid" of what the rest of us will think, to mention it??.... No matter, I'm sore, and "Proud" of it!!🤣😂
I went out today with a more focused purpose, and more time to put it into action! Did about 5-6 hours today!
Same setup, with the Vanquish, and V8 coil! I more or less wanted to repeat the other days hunt, with a wider range of coins, and some added emphasis on finding some oldies, in some curb strips!
Our oldest neighborhoods are generally from the 1920's forward! And have had many roadwork and "beautication" projects, that have destroyed prime "old coin" hunting grounds! But you work with what you got!! So knowing that some of the "tree lined" streets still had their original trees, (i grew up here), I would focus on them for the oldies!!
Between those, and general hunting of this park, adjacent to some of them, I should at least, be able to get a few shallower "older" coins!
My V8 park hunting produced plenty more modern coins, as expected, and was good fun! But also, self-limiting, as that coil doesn't get the depth needed for those elusive oldies that may be there! The soil under the St. Augustine Grass here, tends to be very rich, and easy to dig, with lots of earthworms, so the coins get buried pretty deep, over the decades! Not unexpected, but i was jumping back and forth, from the strips to the park, so I kept the same coil on the detector the whole time! I also have the V10, and V12, so I will go back with those at some point, and test my theory! And of course, the Nox!!
So, to the Good Stuff! One each from just beneath three different "parking strip" old trees! No deeper than about 6 inches, but hidden up against large tree roots! And thankfully, not grown into them!!
A 1942 Silver Merc!! 💖🎊 No nail board test from Monte this time!!🤣
Two 1919 Weaties!! 💕(Same date, two different trees; weird!!)
So now, I at least know that my theory; while producing only a few oldies; is actually sound enough to follow-up with, In future hunts! I can live with that!!
The rest of the hunt produced alot more pennies than I wanted to dig, thanks to two fairly large "penny dumps" in two separate curb strip locations! (Over 100!!🤯) I basically just sat there with my pinpointer, and located them till my legs got numb, and I had enough!!😂 Still more in both spots for another round! I guess there are non-detectorist that hate the pennies as much as we do!!🤣
A rough count puts it around 140 coins total! And I skipped alot of penny's, believe it or not!! So I'm "Tremendously Happy" with the 2 Silvers, and 3 older Wheats, over two days! They actually give me some hope for more now! Or maybe, those where the last two Silvers left in Florida!! So I can leave now!!🤣😂

The weather has been slightly cooler, and dryer here this week! (85 with about 75% humidity!) And my sore foot is manageable now! So yesterday morning I went on a sunrise beach hunt with the Nox, and 11" coil! Conditions were very sanded in, and I only found a few coins, a junk earring, and a lead weight; among the usual junk items! I didn't stay long, as I wanted to do a park hunt too, and not reinjure my foot!
I didn't actually get to do the park hunt till about 4pm today! And decided to use the Vanquish and the V8 coil! I was really only wanting to dig some shallow recent drops of quarters and dimes, on the edges of the park's "weekend soccer field", in a small area, before dark! and avoid most of the trash that is there! It's not very groomed, and is full of short weeds and various grasses! When I drive by, I see the players and family's gather, like clockwork, every weekend! So there is generally a constant supply of easy clad to find, under the nearby trees, every few months!
Today was really no different than any other day I've been there, other than the detector and coil I used this time! I really enjoy the V8 coil for obvious reasons, and in no time I had a decent amount of clad! I had a few iffy targets that I kept track of, and went back around to, after the initial run through! A few were mult-coin spills of a quarter or dime, mixed with some pennies, and maybe an additional quarter or dime! Those were found rechecking the hole, and I knew by the V8's response, that there were others nearby!
One particular target gave me some aggravation, as it was under some weed block, and there was also a mat of small roots to dig thru! This was in a dug out area of one of those exercise stations! I initially got a very clipped "quarter" signal on my first pass, and came back to it later, when the quarter signals got to be fewer!
So back to it a second time, and not wanting to dig a big hole, it took a while to locate some targets through the obstacles, and small hole! I knew I had some iron mixed in, when the first pinpoint was a rusty nail! These "targets" were roughly about 5 inches down, and being a "dugout" area, actually got me down about 10-12 inches below the sod area! So detect, dig, pinpoint, a few times, and finally locate the "Beautiful Sight" of my dodgy target! A Bright Smiling 1951 Silver Rosie! 😃 Very satisfying, as the only silver I've found here before, was a nice money clip, and some cheaper jewelry! The silver coins where "all" vacuumed up years ago, and any left have gotten deeper, or totally out of reach!!
My main theory though, is that all the rusty nails had masked this one! And with my small V8 coil, and the added depth I was able to get, in this "low" spot! I found one of the few that were missed!
When I got home and washed off my coins, and set them out to dry and examine! I got another nice little surprise, in the few pennies I picked up! A 1920 Wheatie (And yes, looks like i nailed it!! 😔) That was probably even more rare here, as it predates the park by about 30 years!
So, nothing earth shattering by most of the standards of what you all find elsewhere! But for my area, and the start of detecting season here, this is about as good as it gets! Short of private permissions, which are hard to come by here!!
The pictures include my previous day's beach finds in the upper right! All the crusty nails where around the immediate area of the Rosie! And the Wheatie is near the Rosie in the picture! I have no clue which hole that came from! That was just a bonus!!👍👍
Good morning, everyone I would like someone to explain how the iron volume exactly works on minelab Vanquish 540. I am using low iron bias and maximum iron volume and, in some coins, when I detect them, it is created a non-ferrous sound mixed with ferrous sound like when you are detecting trash. What am I doing wrong?
I’m completely new to metal detecting and the vanquish 540 is my first detector. I am hoping that someone can provide some advise on the random signals I am picking up. Whilst detecting in woodland I am frequently getting signals that range from 6 to sometimes as high as 39 in the exact same spot, when I dig it up most of the time it appears to be iron nails or other iron objects. I was expecting iron objects to show as a very low number or even minus figures. Has anyone else experienced very high numbers for iron and how do you know when something is worth digging? I have iron bias set to high so that should help but doesn’t seem to. I have found an old coin that showed a reading of 16 so it’s very confusing to know what to dig and what to leave. Thanks for any advise you can provide.
