Using GPX 4500,,,not the detector for sites loaded with iron.  In the hands of a person who knows what they are doing,,,a smaller coil might help.

As far as depth on silver coins (smaller),,,this being a high conductor,,,is not where the GPX is at its best,,,better on lower conductors when it comes to depth.

Also,,the tone arrangement,,,how it works on GPX,,,,high conductor sounds more like iron,,,,versus a lower conductor.

Nail reject on GPX 4500,,, it will help a person out,,,not foolproof,,,,full length nails with nail reject run at setting where depth is less compromised,,,you are talking around 6" depth for rejection,,or identifying as ferrous material.

Smaller bits of nails/iron,,,or larger iron,,,this 6" depth will move around.

Iron reject and GPX better where iron is more sparse.

In medium or mild ground,,,a good Vlf using AM will do more for you,,at least give better discrimination for say the first 7-8",,,, nice if you have Vlf detector that will give ID when in All Metal,,,not all Vlf detectors do this btw.

A person could use a GPX in milder ground,,,and it may prove beneficial say in a site already hunted with VLF detector,,,where ferrous material seems is limited,,,and where nonferrous targets discovered seem to be deeper.

Sorta like cheating,,,using Vlf detector to scout site.

Also should say,,using GPX vey possible to find shallower nonferrous objects,,,,where smaller/smallest iron particles will indeed confuse Vlf detector (no detection in disc),. Yet GPX will power right through and expose object tonally.

Even possible for fine size nonferrous like foil/shotgun birdshot,,,could do this to a deeper nonferrous target,,,and again GPX has a higher likelihood to power right through and detect object.

So GPX is not just about depth,,,can unmask targets too.

Thanks for the write up, thats really good info. ive looked at tonnes of videos on youtube to find out as much as i can and this has been the most helpful i really appreciate it. once again thank you for your help

Hi, Paul;

I used my 2200, gp extreme and 3500 for drysand and slightly wet salt beach sand...the iron can drive you nutso...I found a buffalo nickel while gold hunting in tough ground that was much more than 12 inches...a brass button at least 16 inches...no reason why the 4500 would not do the same...plus it has several settings...

I would get a ctx before I tried a Minelab PI for coin hunting...I don't need to get any crazier...haha

fred

Hi Fred, Thanks for the info. Ive heard the 4500 dont discriminate very well past six inches but its to use on the fields thats bashed out. Ive got some really good permissions thats had alot of the trash took out so signals are few and far between. The problem im having now is depth, my detector is struggling to get good signals past 14''. and theres loads of iffy signals and when ive dug them they've turned out to be small Roman silvers and deep hammered silver. so there's still quite a few good finds there to be found. Thats why i thought by getting one of these machines i wouldn't miss anything if its there to be found. Ive heard the CTX units are good but do you know what sort of depths can be achieved on small silvers and gold because the Etrac which ive heard for friends is nearly on par with the CTX but struggles on the deep gold. Theres nothing wrong with them and not to upset anyone who uses these detectors there all top machines just with different strengths and weakneses thats all. Paul

would anybody know what sort of depths can be achieved with say a small 20mm silver coin with the GPX 4500 on average ground. i know its a tough question to answer but im just trying to get a bit of an idea what these units can do. all the videos on YouTube are about gold and not coin hunting. so if anyone's had experience with the GPX detecting coins i would love to know before taking the plunge. thanks Paul

No need for that idaho - looks like paul is going for that 4500 so I am the one that will butt out now! 

HI Steve, ive looked at the GPX models and there awesome units but i think if its going to cost me £2000 to £2500 its a bit too much for me at the moment. something to aim for though. ill certainly be keeping an eye out for one of the GPX models,nothing comes close to them. I did originally ask for something with good discrimination but the difference in depth is unbelievable. its maybes the way to go. slow and dig everything! at least i won't miss anything but thanks for you time and all your help its very much appreciated ?

Hi Ringmoney thanks for helping me out. i had a look at that detector there advertising GPX 4500 but its a 4000 not sure why?

Paul- only one place to get it....Robsdetector sales...he's on a new post over at gpx5000 not working....best deal if you dont want to be tied to the battery cable.....Check this forums classifieds Right Now!......theres a detector 4500w/docs goldscreamer 500buck kit...looks unused,,,,and its from Rob's...even better.......seriously ....youlll figure out what silver sounds like....Your the discrimination........go watch my Mate's videos on youtube Thenuggetmagnet.......go from oldest to newest  and you can eventually figure out the "Pull"   and what he considers His Favorite Sound...Cheers, jd

just checked out the GPX 4500 its a no go he won't ship outside the US because of the lithium ion battery. shame it looked a decent package. thanks for the pointer anyway?

Seriously id go for Minelab gpx .45  00 thats what I carry fully loaded everyday with a nugget finder advantage14" round . You'll clean up! And you can thank me later! Cheers, IG from -15c Idaho USA

Hi Idahogold, thanks for the info. silly question but do you know where i might be able to get a GPX 4500 and how much are they? would a £1000 get one lol.

 Sounds as if you got a great machine now so why put out more for another. I had good luck with a TDI on the beach and it had great depth there.

Keep your detector and keep your money in your pocket but don't stop swinging that detector.

Chuck.  

Hi Chuck, Im starting to think i should just persevere with the detector i have. But thanks for your thoughts anyway. HH

Those are some amazing depths you are getting already Paul!  Makes me want to go buy a Fors Core to try out. I have never been able to punch past 10" on a dime or 12" on a quarter with any detector in my soil.  Your doing great!

Bryan

Thanks Bryan. you should try one some time you'll not be disappointed unless your wanting to go deeper than 14'' lol. It is a really good machine.

Honestly, you are getting depths far in excess of what I would expect in my ground. 12" to 14" on small silver coins is about as good as anyone can hope for with any VLF detector. Just my opinion - I am sure there are others.

Hi Steve sorry for the late reply and thanks for your opinion.I know im getting good depths with detector i have but i was just hoping there was some other machines out there that would get that little bit deeper on silvers. As the detector im using at the moment is fully upgraded and i can't get any better depths with it. its just a bit frustrating knowing theres older and better finds there. Thanks again and HH  

Hi, im after some advice on metal detectors. I live in the UK and im currently using the Nokta fors core with a 15'' coil for coin and relic hunting but im looking to buy a new detector primarily to search for Roman silver coins and hammered silver coins only. The sites im currently on are rich in history finding coins form Julius Caesar Roman through to Elizabeth II. But im only getting finds up to 12' to 14'' max' with the detector im using at the moment and feel as though im missing quite few finds. Does any one know which is a good detector to purchase, hopefully something good on mineralised ground discriminants iron well and goes verry deep on small silver coins hopefully well over 12'' to 14'' . I know its a tough one but any help or advice is verry much appreciated. thanks paul
