Is a silver signal really silver?

Post by shaggybfc » Mon Feb 12, 2018 8:43 pm

Hi all, I have the Ace 250. When out on the pasture field on Sunday, I picked up a great silver signal - max bar on the scale, showing at 6" deep. So with excitement, I dug out the sod and located my silver item. My excitement soon passed when I saw what looked like a modern looking furniture knob or foot with some mortar stuck on it. Once out, it still returned a maximum bar - Silver signal.
So my question is, what other metal would return such a strong signal?

The 'silver' signal doesnt mean silver per se, just high conductance target. that could also be copper or bronze too. Even large iron can give a false high signal. Good luck.
As the Germans 'might' say:-

"SchvinginbleepindigginundFindenstuff!!!"

new XP Deus/11in coil: 1 silver sixpence 1 foot down!! most impressive.

I’ve a deus and on this you get high tones for all the following so I imagine big lead, or 50cal bullets,Bronze etc will have the sound of silver on your Garrett. Unless it’s small silver.
2018 hammies. = 69(including quarters, halves and broken)
Saxon = 3
Celtic. = 1
Silver denarius = 1
Gold ring. = 0

My Hammy came out an unimpressive 30 and have yet to have a silver come up as silver. Though I'm
new to this, mostly a large chunk of iron comes up as silver with iron undertones on the vdu. I wouldn't take too much stock to the vdu and use it as secondary consideration to the sound.
I am using a different machine however, but from what i gather no machine can accurately predict metal content.
It's a thing i've been struggling with too... and lots of iron later...

The scale on the Garretts (and possibly other machines) are in my experience, along with target depth, next to useless. I used to pay attention to the number/readings on signals on the 400i as I was learning to use it but ended up merely going by the tones. I've subsequently done the same with the Deus.

Personally, I trust my lugholes more than any readout, but others prefer the numbers. Depends what suits you.

Thanks chaps. I've never had a signal that's was consistently so strong. It was such a clear 'ping'. With the likes of copper, aluminium and lead, the signal was strong but jumped a few notches.
But hey, it does go to prove - 'Dig everything'

Perhaps the shape contributes to the super strong sharp signal?
On my GMP a big round rusty as iron ring will sound incredible and sweet....
Or not.
Either way..get it dug up

One day the iron washer will turn out to be a gold merchants ring

Agreed.

Depth
Size
Orientation

A detector has no idea what's in the ground. It assumes everything a average coin size

The best discriminator is the spade.

About the only thing that you can do with a silver id scale is to test whether a coin sized object actually out of the ground is likely to be silver. Even then most times your eyes will be much more reliable. 😁

I have a great collection of galanized horseshoe nails. These give off a great signal and the double ding.

Quite a learning curve, isn't it; and somewhat off putting to newbies?

I remember swinging my EuroAce over my regular beach and getting a nice top end double ding signal. Investigation of the target produced a lovely gold signet ring but five minutes later an identical signal produces a broken, copper jacketed, lead/antimony filled, 0.303 WWII projectile. You win some, you lose some!

After eight years of regular detecting, I no longer take any notice of detector depth indications and treat target id with a little scepticism. Some discrimination is to be welcomed though and if you doubt that try swinging a CS4PI, a machine that has no discrimination. The CS4PI is a superb beach machine, that is totally unphased by saline beach sand but will have you digging for the Olympics on a scrappy beach!

Stay safe, stay well, and if it rings dig it.

If it beeps dig it. Even on top end machines it generally means nowt. Got a 25-?? On 3030 which when got out turned into a 12-?? With no iron in the hole. With the dues with hf coil been getting 72 's that have been deep iron. The only time I take notice of no 's is on clean beach and then 86 woz generally old £1. BUT not always 100% I think most machines are calibrated for US coinage ?

The only real option is to dig them all unless you are one of the rare beasts who are comfortable leaving Roman gold in the ground. :D

As I keep banging on about the target IDs at depth (numbers or sound) are even more suspect than when targets are shallow. With the CTX if you take out a spit and the sound gets more irony then it generally is iron but if it improves then it is probably deep non ferrous. ::g

Yep Fred on 3030 if it spits you have to go back over it slooooowly. It's an annoying thing doing it poss 2/3 times but it is what it is. Silver hammies on dues ive had from 38 up to 82 so far. There's been no coinage below 30 other than I havnt walked over it yet !!!! Prob missed loads by having what disc I do run.

quite common on many metals and minerals too ,,stainless steel bolts and washers are just like silver TIDs..
