Numbers and stuff!

Post by jonahjones » Thu Jul 05, 2018 7:54 pm

Thanks to work, not been able to get out recently.
Now I’m on holiday out in France I have had a chance to play in the garden.
Much to the wife’s dismay I have dug a variety of holes, but at least it’s warm and sunny so the dogs aren’t traipsing in mud!

So, on the basis I am new to this game I’ve dug a variety of targets to try and get what the display is telling me.
Using my wedding ring as a cal piece I list the finds below.

Gold ring 9ct. 79
Aluminium band. 85
Aluminium bottle closure. 79
Galvanised or zinc plate. 84
Tractor tyre schreder valve. 85
Old nails 33
Non specific metal object. 01?

The scale one the device shows foil as mid range so why are they appearing so high up?
Sensitivity was 5 for all items.
I have a few 91 92’s which I haven’t dug on basis they are likely to be dud, or should I just dig everything over 40?

As usual any help gratefully received, and paid in beer if you can find me!
Ps how Do I post a pic, I used low res on my iPad and it said “file to large”

Ignore the scale on the machine. Foil always gives a good reading but the 400i is pretty good at giving you a slight iron buzz in there somewhere which gives a clue. But you'll end up digging it anyway!

Your other numbers look about right, but you don't mention coins. I always get a sense of anticipation when 85 pops up as many copper alloy coins and artefacts have come up around this number. Anything over 90 tends to be rubbish but it never does any harm to dig it anyway, just to be sure, but if you're in a particularly trashy area this might prove tiring as well as unproductive.

As for resizing a pic, have a look at viewtopic.php?f=42&t=99127

Thanks for the reply!
My garden has had about 300 years of use mostly small scale food production.
I have tracked a target for 20 feet at 6” down which I’m assuming is a bit of wire, curiosity wil get the better of me some day.
I haven’t tried headphones yet, no neighbours to annoy, so perhaps I might pick up that iron buzz you mention.

Good advice on the pic resizing!

Pure solid large silver should be quite high numbers ??

Well it is on other machines.

The quality of the tone is just as important as the numbers ... a grunty 67 is probably a 4-hole button, but a cleaner 67 tone, may well be a hammered ....

also use the 400i. Here is a copy of info I recently sent to another member.
Silver No`s for the 400i from coins i have.
1860 Viccy Shilling =91
1911 George V shilling 93.
Would have expected both to be the same at 91.
1860 is heavily worn and virtually a Silver disc, 1911 not too worn and has black tarnishing.
Bought both of those years ago.
Also recently found a Louis XIV, 4 Sols 2 Deniers 169?, which is wafer thin at around 1.4g and has a Silver content of 79.8% this comes in at 77.
Normally use Custom mode, with 2 off Max Sensitivity but all the above were detected on all 5 modes.
Probably got around 100hrs in on the 400i, on inland sites but only 2 Silvers, the other being a Vespasian Denarius, which i can`t locate at the moment.

Would dig those 91 and 92`s to check what they are. Tend to discriminate below 60 and the interesting items appear to come in around 70 to 93.
Hope this is useful.
Good Luck ::g

I have been using my Fisher F44 since January and now have a much better idea of what I am detecting than when I started. I used to come back exhausted after digging everything! Now I look at where I am walking, enjoy the scenery and just listen to the sounds. I have the F44 set to give a quiet iron grunt, which has helped, especially when I am over big lumps of iron that give a signal up in the silver range but with an underlying iron buzz. I now try to predict what I am over and dig some to test my increasing skill. On one recent occasion I was delighted to be certain I was over a coin - and was. Unfortunately, the many discarded bottle tops I dig give the same signal as the post war French aluminium coins I find in this area.

Enjoy your holiday and bonne chance! ::g

Great set of responses, thank you,
Dave the slave has a good point with discriminate below 60and dig every thing else.
I went for another 84 this arvo, turned out to be another non-specific galvanised piece.
Skytriker I have a 1948 1 franc coin which I found n the garden, using a toy marlin detector, which is why I got hooked!
It shows up as 74, just 5 short of 9ct, i’m Going to wait for the winter and urn my garden upside down!
I just love fishing, who cares if you have to through a few tiddlers back!
