    My First Roman Silver With The Nox

    Sounds like a great location - Watling Street. Now that's a real Roman Road. Have you tried looking at www.lidarfinder.com ? You may see some ground works that could be Roman, - rectangular stuff. Or I wonder if anyone is publishing the recent aerial photos mentioned in the news in this hot weather. Of course, the challenge is getting the permission. I heard someone say the other day that they never find anything Roman beside a Roman road because people don't stop until they get to a way station. But I suspect that there would be burials along the way, and maybe shrines. Are you sure you need a deeper machine? The NOX gives me signals that I'm not prepared to dig as they are more than a shovel's depth and I've got limited time. My challenge is deciding what not to dig..... Cheers Clive

    My First Roman Silver With The Nox

    Thanks for that, more luck, I was not far from a Roman road, so I decided to check a slight rise in the field nearby... When I dug it, it was hard to pinpoint, - lots of mud and I think it got stuck to my boot!. I tried using the detector on my boots to check but of course the eyelets gave off a signal, - would have made a good sketch from The Detectorists! Anyway, I've learnt a lesson, I'm going to use signal-less wellies from now on.

    My First Roman Silver With The Nox

    Correction Field 2 used
  4. My first Roman Silver found with the NOX, Field2. VDI 14/15, default settings 8 inches down, 4 units on the depth gauge. Lovely tone Believed to be a Silver Denarius by Septimus Severus AD209, This side Minerva, the other side the head of one of his Sons either Geta or Caracalla, commemorating the victories achieved by the Romans led by Severus and Caracalla in Scotland AD209 -10.

    6” Coil Test On Freshwater Beach - Gold Ring

    Hi NCtoad. Thanks, the reason for my question is that often when I detecting what I call a variable ID object I do get a different Pinpoint ID from the search ID. I find it is fairly common. I've no doubt that when the target is a nice symmetrical coin then the two ID's will be the same, but when you get an object where the search Id is say varying on each sweep say 13/14/15/19 etc then when you switch to pinpoint the ID may be consistently 12. (I've noticed it tends to be on the lower end of the scale). I was wondering if pinpoint was using a different algorithm to the different search modes and whether it would be more reliable as an indicator of the object. (I've also noticed the depth Indicator is often different in the two modes as well) I guess that in your theory, what I am seeing is the last search ID indicated being "grabbed" and displayed in the pinpoint mode. Your model is a good simple explanation but alas means there is nothing extra to be gleaned about the ID of the object. I'm hoping that someone from Minelab can confirm how it works....
  6. Hi Unearth, great questions. My standard approach has been to use Field2 or Park2 and to double check my +ve signals by seeing if there were any -ve figures in AM, and if so, to walk away and not dig. Now this is my approach in typical English fields. I would get say a 100 signals in a field and say only dig 10 of them because of the -ve numbers in AM. Of the 10 I dig, I would still get about 60% of them turning up as corroded metal (not showing any -VE in AM), some as horseshoes. - The rest would be coins and interesting artifacts. Now I've wondered what I'm walking away from, conscious that iron could be hiding a finder, so occasionally, I'll dig out a signal which has a good signal and negative ones in AM, but to date, I've never found a good object. Now so far I've just been using standard settings, not changing Sensitivity, Ground Balance, etc.. but this last weekend I was in a field where in one really large area (half the field) every step I got -ve figures in AM. Now what I do not know was there genuinely there a lot of ferrous rubbish or was this just a local mineralization issue, and regardless of the cause, what is the recommended remedy anyone? Is the answer to ground balance to make the -ve's in AM go away, or should I turn down my sensitivity? - Any recommendations?

    Detecting An Iron-age Axe Head

    Thanks GB-A, I've tested a rusted c20 one, got similar 13 then 14/15/26 depending on orientation.
  8. A request for advice. What VDI would you expect to see when detecting an Iron-Age Axe Head with the NOX? Anyone got one out there that they could test? I've got permission to dig a great site for one day only this weekend close to a Monastery, an Iron-Age Fort and a Norman Castle. Normally I would use Field 2, All metal and no-dig when there is an All-metal signal. Often in a field, I'll get over 100+ signals, (The nox is brilliant in detecting, much more depth than my old machine. The challenge is knowing when not to dig!) and will only dig a few clean signals. Because this site has great potential I do not want to miss out. In my past experience, I've found a modern rusty ax-head and its signal with another machine was all over the place.

    6” Coil Test On Freshwater Beach - Gold Ring

    hi tnsharpersooter, great feedback. A question. What was the VDI for the target. Did you see a different ID when in pinpointer mode? Cheers CH

    Which Mode? And Why?

    Hi Belgy My boring bog standard advice is to start simple and follow the guidelines. Choose one of the modes that seems most appropriate for your locality as per the handbook. Gain experience in that before changing any of the parameters. Use all metal mode to double check the targets for Iron presence, initially dig everything to validate and build a model of behaviour in your mind. Try out different test objects in your backyard - good control environment. I like Field 2, but depends on your environment, I detect in the rolling fields of Devon, but when near to the Farmhouses I use Park 2 as more trashy, but target rich areas. I keep it simple to avoid confusion. Frankly it all depends on where you are and what you want to target. I see that lots of our US cousins focus on coins in Parks, whilst in the UK, many of us are interested in anything old (artifacts) in fields. But then sometimes we get fed up with digging plough shears, horseshoes, eyetubes, shotties, canslaw etc and have days focusing only on coins and digging very few targets and missing out on the interesting stuff. All good fun.

    Minelab Equinox Vs Silver Hoard

    If I had wanted to detect a glass full of silver sitting on the ground I'd use my MK1 eyeballs (or Mk2 if you have glasses/lenses) not a metal detector of any sort. Come on let's get realistic, who goes around depositing bits of silver in a glass on the ground surface in wooded areas!, maybe the fairies? Being constructive, what it does tell me is that if you put a jumble of metal 3inches off the ground, then you get signals you would not initially expect. - Thanks for that insight. Thinking this through, this is a highly complex target, some of that silver is in plastic cases, some not touching other pieces, its all above ground with no earth in between, so one cannot assume it's one large target. Not something that any detector is designed for. I do not know if the author is trying to rubbish the nox, with meaningless examples, or just get publicity, but a more insightful test would be to dig a hole, take the silver out of the plastic cases, pile it in and pack it with earth. - Much more realistic example. I'd been interested to see that.
  12. I'm about to do some detecting in English fresh water streams, I assume that the Beach modes are best suited for salt water, so I'm going to use my favorite Field 2 mode in all the default settings, any suggestions? I assume that what I could find is maybe some tiny gold nuggets, silver coins, and misc jewelry and artifacts that have yet to corrode away in the water.

    Improving Depth Detection Tips

    Thanks again Steve, several great new insights, the key being that signal strength received is used as the main depth indicator. Does that mean if you discriminate out certain tones/ID's then you may be reducing the overall signal strength received, and then the depth Indicator may show shallower than if in All Mode? - Apologies if the question is irrelevant - You've made it clear you use other techniques to judge depth.

    Understanding All-Metal Mode

    Thanks Steve. Your reply was crystal clear, no confusion, confirms my understanding. As usual, you've not only answered the question but provided some useful further insight. Thanks again for running a brilliant forum.
  15. Hi, I'm looking for tips about how to tackle high trash areas specifically when you get multiple varying signals in an area. Often I'm detecting in Orchards or pastures right next to farms that would have seen activity going back hundreds, maybe a thousand years. Or my back garden an ex-orchard in a rural village which over the years has been cultivated, had bonfires, lots of activity. In these areas I get many different signals all within a few inches of each other. Generally using P2 or F2, (I like 50 tones) and I prefer not to change any other settings, I dig out any stable solid figures/tones from say 7 onwards if they have no low tones/numbers when I test with All-metal mode. Having done that the remaining signals often are a mix of good signals, some good bouncing around, and negative signals. I'm trying to detect the "shape" of the signals, aiming to identify good positive signals that should be dug, but not sure about the rest. If I see a good solid signal say in the teens say with a -negative number when tested in all metal, should I dig in the hope of say a coin sitting over/next to ferrous, or should I leave alone? Often in the past, I've had a dig it all mentality to gain experience, but frankly in these areas that is not practical as I may just as dig randomly and see what's there with a pinpointer and not use a detector at all!
