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.

      I have the pleasure of sporting the worst cold I have ever had. I should be doing battlefield metal detecting, but for the past 5 days I am just enjoying this cold.😡 So, not feeling like doing any real work or going anywhere, I decided since my beach hunts are over until fall, I would gather up and count and post all my finds for the whole season…. A season wrap up, if you will. Since I couldn’t muster up the enthusiasm to do everything in one post I figured I would at least post the good stuff. So here it is – the Gold and Silver finds from last Labor Day thru this Memorial Day. I managed 36 beach trips, not sure how many hours but probably about 250 hours of detecting. The breakdown goes like this: Gold total – 36 pcs, at an average of 1 pc per visit. Silver total (coins and other) – 207 pcs, at an average of 5.75pcs per hunt. The breakdown for silver is: 146 coins consisting of 6 Half Dollars, 27 Quarters, 98 dimes, 15 War Nickels. The other items (rings, chains, earrings, pendants, odd broken pieces etc.… - amounted to 61 pcs. Coming later “someday” will be the clad count, and a breakdown of the junk items to show the ratio of good to bad that comes with the territory. It was a great season for me and I look forward to shifting gears and doing the battlefield hunting and maybe some cellar hole hunting if I get a chance. And since I have neglected my other hobbies, maybe doing some of those until Labor Day.  Most of the gold was found because of the Equinox, probably 75-80% of it. Most of the silver was found with the GPX (at depth) probably 90% of it. Not a great comparison since I have found most of that gold in 8 visits and the silver was found with about 28 visits and I was specifically looking for deep silver, so I did not use the Equinox for that, mainly due to the fact that it was busy finding gold  Seriously, I was too inexperienced to get that kind of depth out of the Equinox, as most of that silver was in the 14" deep range, basically sitting on a clay layer with the sand above it containing small wisps of very fine black sand.  But that combination worked well for me and I'll probably stick with it for a while.

      I will be going out into the real world detecting this morning, going to a freshwater beach....not and old beach but busy on the weekends. I have seen other detectors out there but nothing too fancy.
      We will see how the Nox does...I know lots of bottle caps.

      Any one know if the ctx coils interchange with the equinox beside the mounting on the shaft?

      I have the Nox 600 and love it. But is there any way to keep tones from Park 2 which I like when switching to Park 1, Field 1 or 2, or Beach 1 or 2 ?

      With my previous detectors, the last few hunts here were anything but productive yielding no more than 2 to 3 non-ferrous targets.  Despite a knee high Rye cover crop that I was not expecting, I was able to make a few finds from this heavily worked old home site. It was a quick hunt of only and hour or so due to the cover (I'll be back) but the Nox and I were able to come up with 7 non-ferrous including a 1895 IH penny.   The button came up first and only 20' into the field from where I always park.  This entire area leading into where the old home sat in the field has been gridded with every detector I have had in the last 12 years.  Toward the end of the hunt I head off to the side a bit where numerous IH pennys were found in the past and the Nox did not disappoint.  With a full walk around signal bouncing from 17 to as high as 21 depending on angle of approach and centered, out one popped from only 2-3" deep.  The Racer 2 did well in this spot and all those finds were shallow as well.

      The 800 handled the iron here exceedingly well. Field 2 Sensitivity 20-21, Auto GB, recovery 5-7 depending on the iron and IB 0-1.
