Maybe the finds were light but the trash was heavy. I'm getting nervous that the farmers will show up and I'll be out of the fields for the rest of the year. I've never dug so many bullets, all either vintage non military, or brand new black powder, mostly in the 50 caliber range.
I was hunting a roadside in this field near my house today. There was a horse racing track here long ago, the farmer "killed" the side of the road it was on, not sure whether he did it so I could check it out, but we did discuss it a while ago.
This is only half the road looking back to the entrance, I'm pretty sure it's about a half mile long or more. This field is over 200 acres.
Didn't find much:
A fired musket ball, a ramrod tip, an odd shaped bullet that was interesting enough to keep, a 1912 wheat penny and an unidentifiable wheat, and my favorites of the day, most of a 1600s spectacle buckle and an 1800s 2 piece button. Looks like the button was decorated but bronze disease has taken its toll.
Just before I wrapped up the farmers stopped by and gave me some great intel about this area. They figure I have another week or so before they plant. Great guys!
Hello, now here’s an opener that might just get me banned on my first post!
Bear with me, my intentions are pure :)
Does anyone know if it would be possible to jam an MD signal? The reason I ask is to combat the evident problem we have in the UK with “nighthawks”, illegal detectorists.
Over here, any landowner can grant permission for detecting on their land (with caveats, known historic sites are protected by law). What often happens is that such a permission is granted and a detectorist innocently sets about his / her business. Someone less scrupulous spots this person and assumes there may be something important there, so shows up at night with a couple of friends and the landowner awakens to a field / lawn full of holes, then bans metal detecting.
Historic sites are also looted.
Just an off the wall question, how tricky would it be to build a device to block this on a piece of land? Anyone any ideas?
99% of my detecting is done on central Florida beaches. Since it’s impossible to establish a well stocked test garden at a public beach, I sorta brought the beach home with me and developed my own private beach garden!
I cut slots in two large empty chlorine tablet buckets at various depths as shown from 2 -16 inches. I then filled one with New Smyrna Beach sand and the other with soil...for the few times I land hunt around here.
I embedded numerous examples of ferrous and non ferrous targets into paint stirring sticks. I also have several blank sticks I use for gold and silver jewelry as well as artifacts that I don’t want permanently attached to a stick.
I then insert the target(s) in the slots, each at its desired depth, and start scanning.
This allows me to rapidly change the targets, depth and relative position of each. I can now test for sensitivity at depth as well as separation of ferrous and non-ferrous targets in a variety of scenarios using actual beach sand where I do my detecting.
If I want to test in wet salt sand, I just soak the bucket sand with authentic sea water that I also brought home from New Smyrna Beach...and the Atlantic Ocean never even missed it. 😉
Works for me.....
Whooo, what a week. Back home from the beach, I didn't post my last hunt but I found .99 in change. 51 coins total, 3 rings, military button and some small stuff. No silvers. 😵 Got a 50 Centavos piece and 1 South African Rand, so I scored over $5. Oh, and an Anvil...
My wife got food poisoning (she is ok now), my RV water heater element blew, and the outside faucet decided to crack and blow the knob out. Filled the underbelly with water. That lovely trifecta made us decide to head back a day early.
I love beach hunting! It must be my luck but GB never went higher than 10, I only got EMI near a water tower with cell service on it. Clean, clean beach. You got what the Equinox said you did for the most part. Got many more beaches in my future!
Today I hit the farm, decided to grid a farm house where scouting didn't turn up much. All I found in 4 hours was one 1994 dime and one button. I got a 36 on the Equinox, thought "yay!" And dug a huge crudely cast lead ingot. 😀 It's about 3" wide and is heavy. Yep, back on the farm.
I guess we all have these days, you should see all the bottle caps and aluminum I dug to get this. Yikes!
When I got home I had this waiting for me:
It's a 1954 silver quarter cut to the Equinox coil shape. It came with a bead chain, I replaced it with a snake chain. Thus far I have only found two silver coins! Maybe it will be a voodoo talisman for the future. 😀 I thank everyone yet again for their advice and encouragement.

I always have my ears perked up for something new in metal detectors and metal detecting technology. I’m not educated enough to really get deep into the technical side of it, but I have a general layman's knowledge of the subject.
A couple years ago Carl Moreland, the Engineering Manager for White's Electronics, was interviewed on a radio show. I tripped over a reference to the interview on another forum and checked it out. It is very long, and near the end Carl dropped a bombshell. At least I thought so, but it went unnoticed and uncommented on in the metal detecting online world. I thought about posting it on a forum back then but decided to wait and see what developed. Here is the applicable portion of the interview:
Relic Roundup Radio Show, January 17, 2012, Interview with Carl Moreland, Engineering Manager, White’s Electronics
Transcript beginning at 50:57 mark:
Carl Moreland - “I can mention one technology that we’re working on because the patent has already been published… or the application, not the patent hasn't gone through yet. We’re working on something called half sine technology, which has actually been around since the 1960’s in geophysical prospecting applications. This is where instead of transmitting a sinusoidal signal you actually just transmit half of the sine and you can do that at extremely high voltages and high ? rates and so on. It’s technically not pulse induction but it’s not VLF either and it is a time domain method. And with that we can get really good depth and we can even get target id information and do discrimination and so forth.”
Can you see why I perked up at that? I am still amazed it did not get any notice at the time. Nothing happened for a long time. Then I got this PM from Rick Kempf recently:
Sent 29 January 2014 - 09:04 AM
Was looking for info on my new SD 2100 this AM when I sort of fell down a rabbit hole of old forum posts and emerged reading Whites new patent. About the first thing I noticed was that you were cited in "prior art".
Here's what they cited: http://www.voy.com/76600/7/475.html
The patent is here: http://www.google.com/patents/US20110316541
Is this something you knew about? Just wondering.
I told Rick, yeah, heard about that. It was the patent finally being granted from the application Carl mentions in the interview. It was fun getting a mention in a patent though I think it was just the examiner studying up on the subject and finding my old post helpful in simplifying the subject.
For a long time the Holy Grail in metal detecting has been something that combines the target identification of an Induction Balance (IB or more commonly known as VLF) detector with depth of a Pulse Induction (PI) detector. There have been many promises and false starts over the years, and that was one reason I kept the radio interview mention quiet the last couple years. Frankly, I had half forgot about it until Rick brought the patent being granted to my attention. Notice the title:
Hybrid Induction Balance/Pulse Induction Metal Detector
A new hybrid metal detector combines induction balance and pulse induction technologies. Target signals are generated from a transmitted wave that has both induction balance and pulse current inducing characteristics and uses pertinent sampling of the receive data. Combining the two data sources provides eddy current target identification while excluding ground permeability and remanence obscuration.
Is it time to sing Hallelujah? Well, there is a big gap in between getting a patent and bringing a detector to market. Many patents get filed and you never even see something directly related to the patent. Maybe it looked good on paper but does not pan out well in reality for numerous reasons. So just because White's was granted this patent does not mean something is around the corner. However, they have been working on it for over two years already obviously. And it has been some time since White's put something new out. I do not count remakes of the MXT etc as new. So I think there is reason to be hopeful we may see something one of these days.
John Earle is one of the unsung heros in the industry. He had a hand in many of the best products at Compass Electronics before moving over to White's after Compass went under. To this day I have never used a VLF that goes any deeper than my old Compass Gold Scanner Pro. John was one of the brains involved in that, as well as the White's Goldmaster 3, regarded by many as being the pinnacle of the analog development of that model line. I was fortunate to have met John at the factory some years ago. He is listed as the inventor on the new patent. Half sine technology is also mentioned in an earlier patent filed by White's, again with John listed as inventor at http://www.freepatentsonline.com/7649356.pdf
Looks like serious stuff brewing. Bruce Candy of Minelab makes mention of half sine technology in a patent application at http://patents.com/us-20130154649.html which makes me wonder about the new "Super Gold Detector" he is working on. But it is this most recent patent by White's that seems to put the finest point on it. Maybe the Holy Grail of detecting is soon to be a reality. The fact it is White's certainly gives me more hope than what we have seen in the past.
