Not good on small gold

[Got one hammy]

Read on another forum that minelabs not good on small gold,this cant be right can it,showed someone passing gold earing over his etrac and nothing,cant comment myself as i have never found any gold YET but i will or will i.

I'm afraid it's quite true, Neither BBS or FBS see gold micro jewellery as the conductivity is too low.
With Explorers you can get a slightly lower signal by turning fast on and deep off. If you want micro jewellery then it's a job for the higher frequency machines 14-18 kHz.
Ironically I remember back in the 70's finding the backs off ear rings whilst beach detecting on more than one occasion and that was with the old T/R system.....so much for technological advancement

So how small is 'small gold'

I know that my minelab has found gold items in the 4g range, and also some in the 2g range - what about other people?

Mind you I've never found any hammered halves or quarters, so am always concerned I might be missing stuff....

[Chef Geoff]

4g ? that's huge
Try the back of a gold ear ring, unfortunately gold is a bad conductor (in relation to silver and copper) and when you alloy it it gets worse.

always thought that   i do use explorer in fast on deep off and have found 5 gold coins with it and small bits of gold {smallest 1.1g  but just the usual silver rubbish with the etrac

Huh, get a load of him.  'Usual silver rubbish'   

Send some my way carling.

In terms of conductivity:-

Electrical conductivity @ 293 K
(Ω−1·m−1)
 
Aluminium, pure 37.45 - 37.74
 Copper, pure 59.17 - 59.59
 Gold, pure 45.17 - 45.45
 Silver, pure 61.35 - 63.01

(293K is 20C)

Which in layman's terms means..........................................................
Well, what I said in the first place, gold is a bad conductor

looks like a knitting pattern to me , and no before anyone asks i dont knit , couldnt understand the patterns

I've heard your a dab hand with a crochet needle though

I've heard your a dab hand with a crochet needle though

get trouble tying my shoe laces nowadays let alone crocheting

Feel a bit gutted now,thought if you set noise to number 1 it would run at 15 kh or there a bouts,so shouldnt it be ok on small gold,or is my understanding wrong,

thats due to all those Indian takeaways and beer

according to the e trac book it is transmitting multiple frequencies simultaneosly . full band spectrum(FBS) simultaneous frequency transmission ranging from 1.5-1000khz so it should pick up gold , i have found a half sovereign a foot down on the beach and a few gold, silver, platinum and titanium ring on the local beaches with my e trac and hammered silver gives a very odd sound .
