Infinium and iron - tell me what you know

[Charles (Upstate NY)]

So I ordered an Infinium and this will be my first PI detector. I'm a Minelab Explorer guy so its rare for me to dig a rusty nail. I realize this probably wont be the case with the Infinium but other than switching to Iron Check (which would get really annoying on some beaches that have lots of rusty nails) is there anything else in the tone or shape of the tone as you sweep a rusty nail that lets you say, yeah this target is probably a rusty nail?

The second target I'm not looking forward to digging are zinc cents. Do they sound/behave exactly like gold rings or does the Infinium give you any information that lets you say, yeah this target is probably a zinc cent?

Thanks,

Charles

Nails can be a double and unstable kinda tones. Rusty iron can sound like a more prefered item. Well, you might not want to use the iron check, but I do, and I dont mind it. Helps to determine a target, thats what its designed for, might as well use it. You will, in due time start to notice the tone differences once you get some Infinium hunts under your nelt. Remember its a PI and it loves iron, so you will dig some regardless. Iron check! Good luck.

Nails and bobby pins will usually give a double signal one way and a single signal 90 degrees to that. Pseudo gold coins will give a warble with the 14" mono, where the other coils will only warble to some.

Iron items like rusty tent pegs and nails give a lo/hi tone that give a double blip in one direction of sweep when they are lying flat in the sand and a single lo/hi when end on. In reverse disc the tones will reduce in volume but not by very much when compared to a silver ring which reduces considerably.

The disc of the Infinium is designed to seprate gold from iron. The signal from gold, if it is lo/hi in normal mode will change to hi/lo in rev disc and the signal strength will reduce considerably; If the tone from gold is hi/lo in normal mode it will be hi/lo in rev disc at a very reduced level.

Any signal that changes from lo/hi to hi/lo or that is hi/lo in both modes at a reduced signal strength should be investigated.

When using the Infinium (or any other detector for that matter) as a beach machine it is wise to dig all signals because as I have said on other forums; Too many good targets give bad target signals which means that if you use any discrimination at all you will walk over a lot of gold thinking it is trash.

TID detectors are great when you want to restrict your target range to specific target types

Trying to identify coins is not what the rev disc is designed for, so in order to achieve any sort of accuracy you will have to practice a lot with as many different coins as you can get your hands on, but do not expect the same results that you might get from a good VLF with TID.

The Infinium is designed for gold prospecting in highly iron mineralised ground
