Delta 4000 numeric ID.. i dont get it..

[Leopard11]

Ok did some test on coins I own and know the most compositions. Silver eagle 1toz coin .999 silver = 99 most of the time. 1887 Morgan dollar 95-97. Fake 39mm 1876 s trade dollar(appears to have been brazed or plated silver as it has rubbed away and has a copperish color underneath)comes up 99 every single time(thats one I dont understand I would think it would come up as 91 or something not 99). A 39mm military base comm coin .999 copper = 91 most of the time. A 37mm fake 1875 s trade dollar of unknown composition = 79(that makes sense). A 1948 canadian nickel which is .999 nickel, jumps all over the place. I get anything from 48-76 foil,alum, zinc. That one I really dont understand why so jumpy its pure nickel, I would think the darn thing would be fixated on one ID number because of the composition. BTW the 2 fake trades are weights of 26.5g one the first and 25.6 on the 2nd I know they are fake and I would think the ID would be jumpy on those.

I found the Delta 4000 to be pure junk with a VDI that was never solid or accurate.

Which mode were you in? All metal A, All metal B or Discrimination? Did you use Disc or notch out anything? As with any other machine with a display, don't use it as gospel. If it makes the same tone in discrimination when you swing both ways..dig.
I got one at Christmas and though I haven't used it more than 5 or 6 times, Ive found lots of stuff.

Well It does not really matter what mode im in all give same results in regards to the coin testing I did. The biggist problem I have with the all metal modes is they are not constant signals(like pinpoint is) so I have no idea how large the target is if im getting until I hit pinpoint and waaaaaaahhhhnnn yep its another beer can. Kinda wish it had all metal all on sig then atleast I could hunt by ear avoiding large radius junk sigs. Like you said got a solid sig yesterday going both ways 85-87 was sure a clad quarter at the least and it was a peice of alum. So far ive bought 2 md being a N00b and the best thing ive found so far.. a 1963 dime sitting in the tray of a coinstar machine. Owell I guess that is why they call them metal detectors and not treasure detectors or at the least trash eliminators. Maybe one of the DD coils might get some better results.
