  1. Wow, looks like you had a lot of fun.  I really enjoy digging silver when it comes up.  That Barber is nice.  I've not found many in the last 2 decades but they were fun to see in the hole.  I too use the same coil on my TDI SL, per your advise.  The ground coverage is great and the depth is good too.  It is not uncommon to dig a beer pull tab at 8" in super hot ground.  Not bad.  Thanks for sharing both the story and pictures, it keeps me motivated to hunt.

     

  2. I agree 100%, the smaller coil can make a find, no find difference, especially where the ground is extremely mineralized or their is a lot of metal in the ground.  Jim, funny you should mention those two coils.  I've wanted the Australian version of the 7 1/2 mono for years.  Tony, I can say the heaviest gold ring I've ever found was using the TDI and the 7 1/2 dual field coil in an area littered with both trash and coal waste.

  3. Really grateful to get out and hunt yesterday.  Dug quite a bit of aluminum shards, beer tabs and an occasional nail.  I still get fooled by those pesky nails but that's part of the challenge.  I was almost 100% sure the coins were such before digging.  How you might be asking.  I kept raising the coil until it "audio" was almost gone and then I'd rotate around the target, listening for any irregular audio sounds.   The ring turned out to be 18K gold filled but at least it's a ring.  Today I was using the Super Pulse 350 and I also included a photo of my settings.  One important note, this is not a modern school but an old school where coal was burnt to provide heat for many decades and the waste was spread out on the property.

  4. I use my SL exclusively for gold jewelry hunting and deep silver.  These are old school properties where the burnt coal waste has been discarded for many decades.  This smelted material attracts to a magnet and limits VLF depth to about 4".  For the VLF, any target beyond that is detected as iron.  Since the SL is a PI, I can adjust the pulse delay to basically see past this waste.  In other words, the detector can wait until the signal from these small pieces (coal waste) has dissipated to near zero.  During my 5+ years of SL experience I've found some really nice silver coins and the best gold jewelry items.  A PI is not for everyone and for sure there is a learning curve but I've really enjoyed mine from day one.  I don't always find good stuff but I know the detector can perform, if I just stay with it.  Just my 2 cents.

    Gotta like those finds, Mark! Which coil were you using? I found my first knife a week ago, out on the desert. It was in much worse shape than yours.

    Jim, I was using the Super Pulse 350.  I still can't believe this stuff was found, I was as sure as can be I had this area cleaned out.  Also this large coil is very easy to pinpoint.  Hunted again last night and found this, it gave a lot of excitement until I got home and could see it was costume jewelry.  But exciting to find none the less. 

    Little story behind this ring.

    Got to the site just to learn I'd forgot to bring an apron to put trash in so I had to use my pockets.

    After an hour of relentless hunting, only digging aluminum shards, and beer tabs, I was just about to give it up for the day.

    Dug one more target, which turned out to be a block of iron.  Didn't want to try and get that into my pocket I decided to throw it over in the brush on the boarder of the school.  Threw as hard as I could but the piece landed on the edge of the school yard.  Me being me I had to walk to the location and pick the piece up.  Deciding to detect to where I was I turned around and less than 3 feet from where the iron piece landed I got this super sweet audio.  Rotated around the target and it just sounded good, dug and this is what I found.  Recap the story, if I had not forget the apron I would never had found the ring.

    As you said Jim I think this coil is a sleeper.

  6. Another hunt using the White's TDI.  This might not look like much but these items came from a small area, maybe 20 x 20 that had been extensively hunted with two other machines.  But keep in mind this area is also littered with coal waste and iron.  None of these finds were surface finds, the nickel was about 4" deep and the knife around 5.  I know without any doubts I had hunted this area clean with my other machine.  But I can say, using the other machine I tend to listen and look for the constant, locked in audio and VID's.  And I might add one more thing, the coal waste and iron tends to pull down the ID's of the other machines once the depth gets more than 4", which would explain the finds.

  7. Thought I might update my last post.  Finally got out yesterday for a little hunting.  Went to the elementary school I attended in the 60's.  I had been hunting about 20 minutes and suddenly the detector went crazy.  Constant chatter, did a noise cancel, nothing changed.  Dropped the sensitivity, still no good.  All well knowing some was definitely up I put the Equinox in noise cancel mode, raised the coil about 4' above the ground and rotated the coil like you would a TV antenna to see if I could locate the direction of the EMI.  Sure enough, when I pointed the coil in the direction of a 3 phase electrical line it started chattering and when I rotated away from the line it went quite.  Something had definitely switched on the power line to cause such a sudden increase in line current.  Well, I took my own advise, moved to the other side of the school and suddenly my stable detector returned.  This was the worst EMI I can ever remember experience.

  8. One thing I would try, is get a PI, like the TDI and only look for lost gold items.  I found the largest gold ring to date using my TDI in an iron, coal slack site.  It might be worth a try.  Set the TDI to low conductors, this will silence most of the iron, you may be surprised at what might come up. I will add, I had to increase the time delay to 17 but was shocked when I saw the gold.  And that was at a site that had been hammered, for over a decade by the very best VLF machines in the world.

  9. Finally got to hunt a little at a 150 year old church, with permission.  Spent an hour surveying the boundary around this old church, but didn't find the hot spot I was looking for.  But all is not lost, I have permission to hunt anytime.  Next trip, I hope to hunt closer to the actual church but need to ask and make sure it is okay.  Now some might ask, what exactly is the hot spot you are looking for?  An area where the church members (75-150 years ago) might have gathered for outdoor events and picnics.   That being said, I've pondered on what the little shaft with gears might be.  Maybe some kind of wind up device!
