Recomendation For Very Specific Situation

Recommended Posts

I am looking for the best edge I can get looking for $2.5 gold coin in the wet saltwater sand. The beach has a lot of magnetite and a few nails. This is not a diving situation. It is definitely a situation where the detector will get wet sometimes.

Currently I am using a CZ 21 with an 8" coil.

 

I sure appreciate the wisdom of the brain trust assembled here!

 

Thanks,

Tim

Personally I am a fan of the CZ so I vote sticking with what you have unless you wanted to use a PI. The CZ in particular has a good ground balanced all metal mode that serves well anywhere the trash is such that you can get away with digging everything. As close to a PI as you will get in the water without buying one.

The Excalibur is probably the most mentioned alternative, but I don't think there is enough difference between the two, if any, to make it worth an additional purchase. Just my opinion though.

Thanks Steve, I have never used a PI. In the situation I describe would there be a real world advantage to a PI? Would the 10" coil on the cz 21 be an advantage?.

I am looking for the needle in the haystack.

 

Fisher has been very good to me, every year I call them to order a new gasket for the battery cover before I begin the diving season and they just send me a new one. This year one of the potentiometer went bad on the 21, I was apprehensive at what that was going to cost to repair. When Felix called to go over the repair estimate it went something like this: new face plate $125, upgraded housing $400, upgraded battery cover $ 150, new coil cable and connectors $250, something about headphones and more c notes, etc. And he just keeps going! I interrupted him and said Jesus, Felix, your giving me a heart attack this is adding up to more than a new detector.. Felix says oh no, no, that's not what we are going to charge you, we are putting in all the new modification parts for free, the potentiometer repair, retune and pressure test is $90. Whew, that was much better.

When it came back it was a new detector,  not the well worn and much used one I sent in.

A $2.5 gold coin is a small target so the larger coil on the CZ will not help any except for ground coverage. It could actually hurt depth in a magnetite mineralized beach. And CZ-20/21 coils are hardwired so not just something you swap out.

A PI can give you some more punch in mineralized beaches, but at the cost of having to dig everything. Hair pins you never knew existed with a VLF appear everywhere. A TDI for wading or in my case an ATX for submersed work are both ground balancing PI detectors that do well on mineralized beaches. The White’s Surf PI does not ground balance but can also do well as long as you can maintain an even coil height over the sand. Again, kind of hard to say you need to run out and get a PI though given the trade involved regarding discrimination.

So true Steve, my SL has found more hair "bobby" pins than I knew existed.  And yes you will need to dig it all, but ever so often something real nice comes up.

I would like to add one good point.  Believe it or not I can tell by sound, almost 100% of the time when it's a hair pin under the coil.

But to begin with it all sounded the same.  Now, if I could hear a difference between a beer pull tab and a ring, that would be fantastic.

:biggrin:

As someone with no PI experience, I wondered about that. On the cz 21 it's easy to tell the nails by sound until they get pretty deep.

From a pure technical point of view it sounds like the ATX may best machine on this scenario.

      There is an area of a park that I hunt that I have gone over many times with my CTX, Deus, and EQ 800. I have studiously tried to learn  how to use the many features of each detector to know good targets from questionable ones. Recently friends have expressed an interest in trying metal detecting so I bought a Quest Q20 to loan them because it is simpler than my other machines while still having minimally useful features. Took it out to the area of the park mentioned above to check it out and....you guessed it....found my best find of the past year, a heavy gold plated silver ring. Which got me to thinking.......(always dangerous).
      Its been discussed before of course but I wonder how many of us use all the info and adjustments of our machines to find the good stuff but only end up using all that info almost as a reason NOT to dig. Is that why a new detector always seems to "bring hunted out sites back to life"? Is that why, in the face of increasing technology, beep and dig machines are still out there doing well?
      Knowing your machine(s) is necessary for sure and it's fun tweaking them to get their best. But just what is their best? We've all seen a good strong signal turn out to be something other than what was indicated. Still, there are a few people who can tell an awful lot about a target before digging it and digging every beep is hardly a viable option. Plus you can't sweep every square inch of a site.
      BUT....... I'll bet most of us just outsmart ourselves more often than not. Or is that just me?

      One year ago My husband and I decided to try our hand at metal detecting.We were total newbies with a steep learning curve. We purchased a used Xterra 705 for our starting machine. We downloaded and printed Randy Horton’s Xterra guide and have read it many times.  It is a valuable tool for any Xterra owner. We spent the last year educating ourselves on the basics of metal detecting and getting to know our machine. 
      We are feeling pretty confident about the Xterra except for one issue.  I am looking for advice on any errors we are committing or if we possibly have something wrong with our detector.  We have contacted minelab, but they never got back to us about our issue.  So here goes...
      We are having an issue with TID numbers with in ground silver. We have several old silver coins we use for testing.  They air test  perfectly per published Xterra TID charts. When we place a coin (dime, quarter or half dollar, doesn’t matter) in a dug plug and cover, the coins register as ferrous (-8, -6 or -4) every time regardless of the coil we have installed.  We have the stock 9” 7.5 kHz and the 6” 18.75 kHz Double D coils.  We cannot get silver to register as anything but ferrous in the ground.  The depth does not matter.  
      We usually run in all metal or discrim 1 on occasion.  We go through a set up each time we arrive at a place to detect that includes noise canceling, threshold, sensitivity and manual ground balance, although we usually detect in auto ground balance. We use 99 tones and silver in the ground has a ferrous “thunking” sound to go along with the TID numbers.
      We have reset to factory setting several times in the hope of solving this issue to no avail.  We are out of ideas and possibly need service.  Thank you for reading this far.  Any advice or suggestions are welcome and appreciated.

      I was wondering if anyone would want to share pictures of there display cases, not so much shadow boxes but anyone with larger display cases. I love old and nice ones so thought it would be cool to see some...ive got one i pulled out of a general store that opened in the 1930s and been working on it for awhile getting it cleaned up, also have a smaller one that i literally seen in a junk pile on the side of the road that ive been working on replacing rotten wood and for sum reason they lined the inside with wallpaper so been cleaning that up to.. i found the smaller one and amazingly the old glass didnt even have a crack in it..

      When primary aim is finding meteorites (also with low iron/ nickel content), what metal detector would be a good idea to get (within budget)?
      Minelab Gold Monster 1000 (no manual ground balance, does this matter?)
      Minelab Equinox 600 (no real all metal mode??)
      Makro Multi Kruzer (how sensitive to small objects?)
      Makro Gold Kruzer (unknown when it will ship)
      Other detector (why?)
      Or do I need to spend more, i.e. get an XP Deus? I would very much appreciate any insight or even practical experience. Thank you very much for your time!

      Got out with the equinox, got this old piece of brass i think. Does anyone know what this might be?
