Hi All,

Everyone know that the spendable coins are 61/62.

I've just discovered an 1874 British Penny does too (shallow, good condition, chch park.. but common?).

But what id readings for any predecimal coins other than pennys and halfpennys? How about a plain common gold wedding ring?

What are your oldest finds?

Cheers!

Hi There. I dont own a fisher but i've found that coins can range from low foil right up to a high silver readings, all depends on depth and conditions. Trial and error the only way here. Dig all signals for a while until you filter out the odd ones.

Happy hunting

Silver rings, religious medals and other silver objects should come in somewhere between the dime and the quarter areas if they are normal sized and depending on that size.
Smaller objects like small thin kids rings or small studs abd earrings can come in as a zinc signal.

Gold rings and other gold objects like crosses can come in anywhere and everywhere from iron to zinc depending on the size, karat and alloys it is mixed with.
Really tiny objects like studs or small clasps on chains can come in at iron numbers and can usually only be picked up with the sniper coil.
A little bigger but still small objects and small thin rings can be at foil, a little larger at nickel, larger still at tabs and very large like class rings at the zinc level.
Purer karats will be higher than lower levels...An 18k ring will show up a little higher than the smae size ring that is 10k.

Rings of any type that are split or open can come in anywhere, can be a jumpy signal and might be hard to pick up at great depth because of the way detectors work and something called eddy currents.

The same effect makes it very hard to find most chains of any type or metal so we need to be lucky and hope we scan an end with a clasp to find these.
The same thing can happen with other objects that are not chains but are still open like solid bracelets.

Chains for me have come in anywhere from iron on a tiny, thin gold clasp on an extremly thin gold chain, all the way up to zinc on the clasp of a very thick mens bracelet, but not one has ever come in as a dime or quarter high tone signal.
Except for that one signal on that thick bracelet which was a 61 zincoln number, every other chain has been mostly from foil on up and always a true trash signal.
I dig it all because in cases like this and most others you just never know till you dig it.


If you haven't heard of DIGGER27, go sign up to metaldetectingforum.com and search for him, he has written more than anyone else as on the F2 and has a very, very big thread covering all aspects of the F2 (most applies to the F4 and other Fisher machines too) he has put a lot of info out there!

Thanks guys, that does help. Using F4. Has 7 levels of reject, the 7th being the zinc one where the spendies are. Would still like to know what some interesting nz coins read as, and not sure i'd want to run all metal with some parks like junk yards.

Has anyone had any chch beach experience with PI ring hunting.

I took my F2 out to Sumner and another beach spot a couple of times.

Dry sand was awesome, I didn't notch anything out and was running one bar off maximum sensitivity. Signals were few and far between, some old decimal coins and a couple of dollars.

Wet sand wasn't as bad as I had expected after reading other peoples efforts/attempts. I dropped sensitivity a bit and didn't get many false signals. I actually picked a dollar, a fishing sinker and a junk ring out of the wet sand. For the basic machine the F2 is I was quite impressed.

But I have to admit, as easy as it was to beach-hunt with the scoop (compared to digging in dirt) the large amount if area covered and the lack of any really interesting finds almost put me off beach-hunting. That being said, I think I'll be heading towards a beach this weekend if the weather plays ball.

Still, I've had far more luck in parks.. You sound like you're after coins, maybe ones you can spend (hey, I like them too) in two quick hunts in Hagley (maybe five or six hours combined) I walked out with just over $30 in modern spendies, and all from a very small area. There are also a lot of pre-decimal coins there. Some if the guys are still pulling out multiple silvers per hunt from grounds that have been really well worked over previously.

I'm low on the silver count, but all my silver so far has come from Hagley.. It's a fantastic training ground too!

There's a group of us who often head to Hagley for evening/night hunts (not as difficult as you'd think) all you need to bring is a headlamp and you'd be sorted. So, keep an eye out for posts about that and feel free to show up and say hi.

Generally if you see anyone anywhere swinging a coil pop over an say him or join in. I'm yet to meet an angry or hostile detectorist.. The again I haven't jumped infront of one and pulled gold out either, lol.
