I Struggled At A Desert Rail Stop

Recommended Posts

Yesterday I went out to an old SP stop in the desert. It has a long history but the heaviest use was 1920's-1930's when it had a small post office. Being next to the tracks I experienced EMI with each passing train. There is also an under ground cable that runs along side the tracks that made itself known when I got close to it. To top it off the ground is mineralized. I struggled with my settings. I tried default P1,P2 and F1,F2, did not try the other modes. I settled on F2, 5 tones with the power set at 17. I did not change the IB. Later in the day I did notch out everything below 19 with the exception of 12/13. All the targets were shallow so I assume I could have turned the power down even more. I am open to suggestions on settings, or is this just power v.s. stability ?

With all that said there were targets worth digging. 1892 v and a 1943 war nickel. A military button from I do not know when, lots of junk that sounded good too when covered with dirt. This thing has been suprisingly easy to use, just not sure I was spot on with set up this time. I am going to go back again and experiment with the options.

I'd venture to say you did very well on your first hunt with the Nox  Keep up the struggle it's a very sensitive machine.... we are all learning right now.

Ground around railroad tracks especially around stops can have lot of very fine iron from the steel wheels grinding against the tracks.

Cool finds!  I like that old spark plug..

If everything is real shallow maybe drop the sensitivity even further, or try 15 or 20 kHz and see if it runs better for you..

If there is not much aluminum there I would try digging some of the lower conductors..  Some small cool stuff hangs out in 9 -14 range on the Equinox..

I’d say this instance may be the time to leverage the single frequencies, go through them one at a time until you find a good one.

I remember a similar experience on my F75 LTD2, and no amount of tuning would allow it to hunt next to the RR line I was trying to detect.  Just think if it had five major frequencies to choose from, probably could have had a great hunt.

I've hunted along railroad tracks and have had the same problem with the CTX. My first instinct would be dropped the sensitivity down and then run the recovery speed up. If everything is shallow, then you don't have to worry about losing depth with the higher recovery speeds.

I have to agree with Cabin and Cal.  While Multi is a great tool to have, cycling through frequencies can be a great tool too.  I cannot use multi in my front yard, but 10khz works like a champ!  Good luck and I look forward to your next hunt results!

I didn't notice you mentioning that you did a (EMI) noise cancel.  Even the auto procedure isn't the best in very noisy environments, and it's not that difficult to cycle through all 19 settings, even for multiple modes.

It sounds like you were able to operate at gain=17 and obviously you made some nice finds.  I know from experience that it can be disappointing to read about all the hot, quiet, tight TDI operation that others are getting, but the bottom line is that the site determines what you can run.  The fact that you pulled out some nice targets at the reduced gain setting says you are getting a lot out of the detector.  Definitely wise to ask, but even if this is all your site can handle you are doing well.

To be honest I did not think of trying single freq. There are more options than I am used to. I would like to be able to go over this site smooth and stable. Thanks all for the input.

dwg,

This is a challenging site.  It takes a lot of experience to tame a sensitive machine down.

Steve suggested that people new to the Nox not take it out for a stroll in a nail bed.  There is good reason for this but one of the reasons is to be able to hear the good sounds and control the coil around all the junk.  It is there.

Have you seen Steve's last couple of posts?  He has 'notched out' or rejected everything in the low range.  He has been using the Nox the longest on this forum by far so we should emulate his settings in trash.

An observation I have is if you are looking for 'smooth and stable' in an area like where you were hunting you will have to go a few hundred feet away from the trash and set yourself up.  Now return to the scene of the crime and find those noisy good targets.

      After a fairly lean summer (90 hours hunting from early June to late September), surprisingly that included five permissions, things have picked up over the last three weeks.  Here are the details:
      Hunt 1 in Schoolyard:  4 1/2 hour hunt on my favorite (one of only two) schoolyard, running Park 1, ground balanced, custom 5 tones, Iron Bias 3, recovery speed 6, I got a clean 25-27 signal at moderate tone depth (turned out to be 4 inches) and was very surprised to see a 1912 (common issue) Barber dime.  'Surprised' because 1) this schoolyard was a pasture prior to 1955, 2) (when I got it home and cleaned) the condition graded out AU-53 meaning this coin had seen very little wear/circulation in its lifetime, and 3) I thought I had been over this area previously (obviously not).  Does this make sense?  It certainly is possible that a coin minted 40+ years previously and in near mint condition could get dropped.  For example, a previous recent hunt produced a fresh drop (surface) 1980 near mint Lincoln.  Now having searched this schoolyard for nearly 100 hours I've theorized backfill was brought in 26 years ago when the original school was replaced with a modern one.  So this is my best theory -- I'm occasionally finding coins that were relocated to this site from a considerably earlier drop zone.  No matter, gotta love that silver and the outstanding condition is a bonus.
      Hunt 2 (3.5 hours) in city park established 1948 (previously industrial site first occupied in the 1890's):  This is my EMI noisiest site, one I've had a lot of trouble with in the past with multiple detectors but particularly the Eqx 800 in multifrequency.  Besides buried power lines along the street there is a hospital with helipad across the street.  As I neared the street I encountered serious EMI and checking the individual frequencies saw that the problem was at 40 kHz.  In my experience this is the exception -- most of the time (from underground powerlines, I think) it's 5 kHz that suffers worst.  So..., since I'm looking for coins I chose to run at 5 kHz with gain of 19 (custom 5 tones, iron bias of 0, ground balanced, recovery speed 6).  Hunting in a spot I had never previously searched (thinking it was modern fill) I got a strong copper-penny / dime type signal, thinking likely a copper Memorial or clad dime.  Nope, only about 2 inches down: silver!!  After cleaning it in water at home it showed a 1928 plain (common) date with the reverse in no better than VG condition, but a reasonably attractive, strong obverse.  Always thrilled to find silver and this time no exception.  Note:  the ID's I was seeing at 5 kHz were consistent with multi-frequency ID's.  This is reassuring, that when forced to hunt in single frequency the detector acts as expected.
      Hunt 3 (3.5 hours) in same city park:  While out on hunt 2 I recalled that my new, long-awaited 6 inch coil was to be delivered that afternoon while I was actually on the hunt.  Sure enough, there it was in the mailbox when I arrived home.  Next day was my chance to try it out.  I chose a part of the park I had hunted many times in the past with great success, both with the F75 originally and later with the Eqx 800.  This area had previously accomodated a 1920's home, so quite a bit of iron (nails).  Park 1, gain of 20, custom 5 tones, iron bias at 2, recovery speed 6.  Searching a spot I know I've been over at least once with the F75 and probably twice with the Eqx 11" coil I got a decent (but with neighboring iron hits) nickel zone signal.  Expecting junk (pulltab, canslaw, pencil ferrule, crown cap to name just some of the imposters) out popped a Jefferson 'nickel'.  It seemed to have the typical dark toning characteristic of this kind of coin after being in the ground for a few years, but it wasn't orange color which tend to represent the worst examples of alkali corrosion.  Still, didn't think it was anything special.  Turns out it was my 3rd Warnick (this one 1943-S) of the summer!  Next I searched an area which (based upon the density of trash) I had previously concluded was the house's trash dump.  Running a small coil gives me confidence in such an environment and under a bush I got a very strong penny/dime signal which turned out to be a near-surface Wheat penny (1945-D)!  40+ years lying there waiting for my new 6 inch coil.  My last old find I'm still unsure of depth/location since I didn't remember much about its recovery.  When in old sites I dig anything above 17, even though that means pulling up the hated Stinkin' Zincolns, since Indian Heads and long buried Wheaties can give signals in this low.  I do remember excavating a copper penny which showed no detail at all based upon the amount of dirt/crud it had accumlated over decades in the ground, but at the time I didn't expect anything more than a 1940's Wheatie at best.  Thus I was quite surprised after getting home and soaking it that the reverse wreath of an Indian Head (1896 so over 120 years old) -- my second IH of the year.
      Summary/Conclusion:  Although the Eqx has been an excellent producer for me in 183 hours of hunting, I'm pretty sure any decent detector would have found the two silver dimes.  Neither was particularly masked nor deep.  However, given that I was covering previously well-searched ground on Hunt 3 it sure seems likely that the combination of the 6 inch coil and the unmasking ability of the Eqx 800 pulled those 3 oldies out where other searches have failed.  To add an extra note to those latter finds, over those 3 1/2 hours I only found two other coins -- a clad dime and a Zincoln.  60% of the coins I found that hunt were oldies.  As can be seen in the photo, the dimes are characteristically (for my soil) as nice as the day they were dropped, but the two pennies and even the Warnick suffer from staining and (in the case of the pennies) scaling.  I hope to be able to clean those up in the future.
      P.S. all of the hunts were 'all metal' (no discrimination or notching).

      This is an added document that arrived with my Equinox.  Extremely important.
      Out of the 8 USB chargers in my house, none were UL certified.
      Trip to Wal-Mart is in order.

      Use 5 tone. Set nails at -1 to -3 with lowest volume and low tone. For iron relics set -4 & down and set to a  louder volume and low tone and for non-ferrous set 0 to 40 a loud volume and high tone. Basically a 2 tone low for iron relic & high for non-ferrous. and a quiet tone for small iron. A 3 tone mode.
      With this setting you will hear iron relics hitting a low louder tone and you can dig or not. High tone is your non-ferrous. This is good setting if you want to dig iron relics like I do. Some areas you don't want to dig iron relics you change to 2 tone or what ever you want.   I think it's an interesting setting. The adjustments are great and easy in this detector.   Now all we need now is a 5x10 or 8" round coil.   Rick

      Hi guys !
      Yes, I am a beach hunter, but I was invited to metall detecing on a WW1 field...
       
      So the beach hunter I am was suddenly contemplating a huge corn field which has seen some ww1 Action...
      I chose to hunt before noon (2 hours) with the Equinox 800, and two hours in the afternoon with the Safari I happened to win at a detection rally two weeks ago.
      As you can tell from the posted pics, the Nox Found 18 targets, the Safari 32, but i felt the afternoon search was richer in targets...The best find of the day was a silver King Leopold II 1867 2 Francs (Belgium), a very rare coin, as it has only been minted from 1866-1868
      The nox got more tiny targets (low conductors), but the Safari was able to find some tiny targets too.
      I don't know what to think about the results about both detectors, but they are very close in my opinion.
      Those are the pics of this outing (round bullets are belgian, the others are german).
       
      Happy hunting !

      Hey friends. I remember seeing a post somewhere awhile back about changing the tones on the Nox to sound more like the Etrac or CTX 3030. Anyone know anything about this?

      As I mentioned in the below thread, I received my 6 inch coil yesterday and couldn't wait to take it through the paces:
      Today, during a lunch break from work, I headed out to a local old and pounded park I have hunted countless hours with countless machines.  I have been amazed the life my Equinox brought back into this park.  My early year success is outlined here:
      So, with an hour to hunt, my E600 in hand, loaded with the 6 inch coil and original firmware (I am still testing old vs. new firmware using my E600 with original and E800 with new firmware), I set out.  I was running Park 1, 50 tone, Sensitivity 22 (pretty stable), Recovery 3 (6 on 800) and IB 1 (2 on 800) and walked into the area of the park I have hunted hardest to see if this rig could uncover anything I missed with all my other machines, including the E600 and E800 using stock coils. 
      My first target was a series of bouncy tones across about 4" of ground.  As I narrowed my swings, concentrating on the different tones, I was able to hear one solid mid tone that was 11-12 ID, but a couple of high tones that were more scratchy and not repeatable an inch or two away in two directions.  I pinpointed and it was evident that I had 2, maybe 3 targets there.  I chose to circle the mid-tone first.  While the depth meter on the 600 with old firmware isn't exact, the modulation on the pinpoint told me it was in the 4"-5" range.  So I dug.  I was expecting a pull tab, or beaver tail.  Both notorious for bouncing into the 12-13 range in my ground, but also occasionally giving off 11's and 14's.  My intent was to clear the trash, so I could better hone in on the higher tones sitting near this target.
      A little over 4" down:

      I think it is a 1935... our ground is hard on nickels.  Only my 3rd Buffalo since I started detecting and my previous two were no-dates. 
      I refilled my hole, stood up and swept the coil over the area again... the high tones were still there, and equally as iffy as before, giving me numbers in the 21 to 26 range, and on every other pass or so.  But they pinpointed pretty tight.. I estimated 5"-6" based on the pinpoint tone on both.  A little ground excavating later and out popped:

      Looks like a 40's and a 50's wheatie. 
      I have a little cleaning to do on all three of these coins, and they aren't ground breaking by numismatic standards, but I am thrilled.  And here is why:
      Three old coins that by all rights, should have been found previously, but weren't. I have a suspicion that the closeness of these coins would have given larger coils, even with fast recovery like the Equinox, troubles.  So the 6 inch coil came through in my opinion (I would bet that I was getting some type of blended tone previously... like a 15 or 16 on the Equinox as an example, which I chose not to dig thinking it was trash). In my soil, with the settings I was using, I think I was at the limit of detecting depth with these Wheaties... about 6".  So that is really good information for me.  Not that depth is everything, because I was able to separate between these three targets at depth.  Had I been thinking more scientifically, I would have tried to clean up the tones by dropping the recovery down to 2 (4 on the 800), or boosting the sensitivity up to 24 or 25.  Or I would have walked back to my car and grabbed the 800 with the stock 11" and documented what these targets read, and why I hadn't investigated them before.  Heat of the hunt and a lesche in my hand got the better of me. All three of these targets were dead center in my plug.  Which is somewhat expected when the coil itself is only 6", but just verification that the coil with this rig was pinpointing accurately.  Hopefully more results and finds to follow.
      HEH (Happy Equinox Hunting) to all,
      ~Tim.
