Testing The Minelab X-Terra 6″ DD HF COIL

Hey folks…
I recently picked up one of the little 6″ DD High Frequency (18.75kHz) for my Minelab X-Terra 70. I figured it would help me out in some of the super trashy areas I hunt. The general rule is that those higher frequency coils are better at getting the lower conductive targets (ex. gold) while the lower frequency coils nab the higher conductive (silver) targets. I just wanted a little coil to get in between the junk, and the DD construction helps in my tough ground.
The weather wasn’t exactly conducive to extensive hunting. Temps inlittlecoilsmall my parts of the woods have been in the low 20’s F, but cabin fever forced me outside for a couple hours anyway. I decided to layer-up and hit a late 1800’s homesite that I had hunted once before. The home is now in a field shared with roaming cows and hasn’t been inhabited in about 20 years.
The previous trip was disappointing – the only thing to turn up was screw caps, and a lot of them. To say the site was trashy would be an understatement. Every swing caused 4 or 5 “nulls” in my detectors threshold, indicating an object that was being discriminated out. When I got to the site I quickly did an auto ground balance and set the sensitivity to 24. It was smooth without any falsing.
Just a few minutes into my very cold outing I got my first good signal. I pinpointed and struggled to dig a shallow, small plug. Frozen ground! Ugh. Not something we have to contend with in these parts very often!
Scan plug..nothing.
Scan hole…yep, still in there, but off a little bit.
Widen the hole a little bit…still off.
I finally nabbed the target. A coin!
The entire time I was here last time I didn’t find a single coin. This one was a penny, and I was hoping for an Indian Head. Wiping away the red clay revealed a copper memorial. Eh, oh well. It was a coin. The little coil was doing what it was supposed to.
I covered my hole and kept at it. Not 10 feet away I get another signal, this one a little higher on the X-terra’s meter. For some reason this one was tough to pinpoint too. Then I figured out my error – this is a double d coil, not a concentric! A total “duh” moment. DD coils are “hot” from tip to toe, while concentric coils are more sensitive in the middle. I wiggled the coil over the target, then slowly pulled BACK until the signal went away. Keeping an eye on that spot, I turned 45 degrees and repeated to verify. The object should be right under the front edge of the coil. I dug down, and sure enough, there it was. A dime. Clad. From then on I had no trouble pinpointing and didn’t even use the pinpoint feature of the detector.
I detected in the frigid cold about another hour, dodging cow patties that littered the turf. I received several other good signals, but a few I had to abandon because the ground was rock-hard. I was plenty impressed with the little coil. I couldn’t test the depth limits because I just wasn’t able to dig deeper than 4 or so inches, but a couple of the coins I retrieved were at least 4”. Unfortunately all the coins were modern. I’ll have to give another report when the ground is more “digable”!

Thanks for visiting. If anyone wants to share some experiences with little coils, detecting in freezing cold, digging in frozen ground, dodging cow patties, or anything else, go for it!

Metal Detecting and “Public Property”

Hey folks.  I’m very thankful to my friend Bill Bertke for writing an awesome guest post regarding metal detecting and public property.  A lot of you mayhandcuffs know Bill (Beetle662) from some of the detecting forums.  Well, Bill is also a police sergeant in the great state of Kentucky. 

In his post, Bill presents the topic of metal detecting and “public property” from the perspective of a police officer.    Again, thanks Sgt. Bertke for your time!

__________________________________________________________

Detecting and “Public Property”

Metal detectorists are always looking for new places to check out.  Private property seems to be the key to good finds, but gaining permission to privately owned property is not always easy, let alone granted.  So, we look for easy spots… spots we take for granted that we can hunt anytime.  School yards, playgrounds, and city and county parks.  But I ask you, have you asked for permission to hunt those? I’d be willing to bet most detectorists haven’t!

Here’s the deal.  All of that publicly owned property is governed.  Not by us, but by those we elect.  And those elected officials enact laws and ordinances that prohibit us from doing things that, in general, are not good for one reason or another.  They may have dedicated a street as being one way, or perhaps they regulate parking to only one side of street.  Those matters concern safety.  Do you know if your local government has enacted any laws or rules regarding detecting on public property?  You had better check, because the repercussions could range from a fine all the up to forfeiting your hunting equipment, and maybe even both!

So, if this is “public property”,  I have a God-given right as a tax-paying citizen to detect on it right?  WRONG!  Think about this.  “Public property” is actually owned by your city, county, state, or even federal government.  The “use” of that land is governed by that agency.  And that governing agency sets into place rules and regulations regarding the use of that land.  You couldn’t go build a new house in the middle of that city park you like so much.  What makes you think that being able to detect on that land should be any different?

Rule of thumb… check the ordinances and laws in your area to see if there are any on the books concerning metal detecting.  If you find out that there are laws, then abide by them.  If you don’t like them, do the right thing and petition the appropriate governing agency for a change.  And if there are no laws on the books about detecting that old 1800’s park you’ve been eyeballing over the winter, then you are free to go detecting!

What if there are laws that say I can’t detect there and I want to anyway? Don’t do it!  Fight for change, but fight in the council chambers.  Do your research.  Find out why there is a law in the first place.  Educate the governing agency about your hobby, stressing the positives as much as you possibly can.  Take some of your finds from other areas and show them how rewarding it can be.  Buddy up with a councilman/woman.  Get them on your side by showing them that when done properly, detecting is fun and brings no harm to the public property. Chances are that if there are laws regarding detecting on public property, they are there because of abuse by previous detectorists.  Don’t be a hindrance to future detectorists and cause laws to written because of your failure to fill your holes or leave your trash behind.  Treat public property as if it is your own.  Yes, you do have a stake in by being a taxpayer!  Don’t ruin it for the other taxpayers that want to hunt it too!

How To Add BLUETOOTH Headphones To Any Metal Detector

Hey folks…In a previous article I described a way to set up any metal detector with wireless headphones using an FM transmitter and a small FM radio. I’ve researched a little more and bluetooth_icondiscovered another way to add wireless headphones to any metal detector – this time with bluetooth. I need to preface this by saying I’ve never tried this, but it deffinitely seems feasible and would likely work better than the FM method.

Some web browsing has revealed several models of bluetooth transmitters that plug into a headphone jack in the same manner the FM transmitter would in my prior article. Some models include the IOGear Bluetooth Wireless Audio Transmitter and Sony Bluetooth Transmitter and Adapter. I’ve linked to both on Amazon. Be sure to research these and any other transmitters. One of the reviews for the Sony adapter mentions a lag time, so this could really come into play when detecting.

Once you have the transmitter, then all you need is a bluetooth headset or headphones. Tons are available online.

Again, I’ve never tried this but it does seem like a wireless option for those of you that want to sever the cord!

What do you think? Would this kind of bluetooth headphone set-up work with metal detecting?

Metal Detecting Code of Ethics (iDetectorist Style)

Posted on November 8, 2009, 10:44 pm, by wayne and received No Comments ».

The Metal Detecting Code of Ethics is a guide as to what you should and shouldn’t do when metal detecting.  It is printed in most metal detector operating manuals and plenty of sources online.  shameI’ve revised it a little bit to reflect some of my detecting do’s, don’ts, and pet peeves.

Here’s the iDetectorist.com Metal Detecting Code of Ethics

  1. If in doubt, don’t.  If you’re not absolutely sure that you can legally detect somewhere, don’t detect there until you ARE sure.
  2. If you have to keep looking over your shoulder while you’re detecting, you’re probably violating the first code.  That, or you should be there with a buddy and not by yourself.
  3. Don’t take a shovel onto a park or school ground.
  4. Don’t take a knife onto a school ground.
  5. Dig your plugs the right size the first time.  A larger plug that gets the goodies is neater than a smaller plug that you have to make larger.
  6. If the landowner asks what you found, show him.  Don’t have a secret pocket where you keep the really good stuff.
  7. While you’re at it, show the landowner the trash also.
  8. Sometimes it’s OK to leave it in the ground.  That ten food pipe doesn’t have to come out.
  9. Don’t bust on the guy with a low cost detector.  All detectors are toys – the $150 one and the $1500 one.
  10. Leave the place like you found it.  Go back later and assess your damage.  Hopefully there won’t be any.
  11. Just dig up a piece of trash?  Don’t toss it into the bushes.
  12. If you’ve dug a foot down and a food wide, and the detector is telling you it’s a coin 2 inches deep, its probably not a coin.  Get your back-hoe and move on.
  13. Found a silver coin?  Don’t rub the dirt off.  Wait till you get home and soak it in water.

So there you have it.  Surely I left off a couple and that’s where you come in.  What would you add to the list?

How To Add “Wireless” Headphones To Any Metal Detector

Posted on October 31, 2009, 10:12 pm, by wayne and received 13 Comments ».

Ever get tied up in your headphone?
When you kneel down to dig a target does your headpone cord tip your detector over?
Does your headphone cord get in the way of your digging?

I’m going to show you how to add “wireless” or “cordless” headphones to any metal detector.

What you’ll need: An FM transmitter, a small radio, and headphones.

An FM transmitter is a little gadget that accepts a sound signal and sends it a short distance by FM waves. They are generally sold as automotive accesories for playing an MP3 player through your car stereo. Some of these plug into your car cigarette outlet, while others are battery powered. To use with your metal detector you’ll want one that runs on batteries. Well, unless you plan on detecting in your car. You’ll also want a transmitter that has a standard heaphone connection (usually 3.5mm) rather than an iPod or specialized connection. I’ve had good luck with the Belkin Tunecast models. The more available channels that the transmitter can send on, the better. This way you can find an “unused” channel for clear reception. Here’s a Belkin Tunecast below:
belkin

The next item you’ll need is a small FM radio. A digital unit will work best as you can get a good solid lock on the channel. The Sony FM Walkman radios work well, but I’m sure good results can be obtained with any small digital FM stereo. Small is good.

Finally, you need headphones. This is your call, as any headphones will work. You’ll want good quality sound, so don’t go cheap. There are great HIGH quality phones from earbuds to full ear covering units. The good thing about this setup is that during the winter you can go with larger “cans” to keep your ears warm, and in the summer you can switch to lighter earbuds.

Now to put it together. Plug the FM transmitter into the headphone jack of your metal detector (you’ll probably need a 3.5mm to 1/4 inch headphone jack adaptor). You might stick the transmitter to the body of your detector with velcro to keep it out of the way. Whatever works for your detector. With your headphones plugged into the radio (not your detector!), turn your FM radio on and find an unused frequency. Then turn on the FM transmitter and your detector. Set the FM transmitter to the same frequency as the radio. Thats it! You might have to adjust the volume of the radio to a comfortable level but you’re ready to go. Clip the radio to your belt, in your pocket, or wherever appropriate and enjoy tether-free detecting.

Simplified:
FM transmitter plugged into detector.
NOTHING connects you to detector.
Headphones connected to FM radio.
Radio on your belt loop or in your pocket.

Enjoy.

Metal Detector Pinpointer Roundup

Posted on October 11, 2009, 1:22 am, by wayne and received 6 Comments ».

A pinpointer is a must-have when metal detecting.  In fact I would consider it the most important metal detecting accessory after a good digger.  Yep, even more important than good headphones if you ask me.

Why do you need a pinpointer?  Coins and such can be hard to see!  Not to pinmention they can be hiding in the wall of a hole while you’re digging to China.   Turn on the pinpointer, scan the hole or the clump of dirt, and beeeeeeep, you have your goodie in-hand in no time.

Here’s a roundup of some of the more popular metal detector pinpointers on the market today.

  • SunRay In-Line

Some would consider the SunRay In-Line Probes to be the cream of the crop.  These pinpointers work as a secondary coil on your detector.  Flip a switch and the pinpointer is active rather than the main coil.  This gives you all the tones and readings that your detector would normally have, except with a tiny coil. Somewhat pricey compared to other pinpointers at around $170. More on Sunray at their website here: Sunray Detectors.

  • Garrett Pocket Probe

The Garrett Pro-Pointer is a relative newcomer in the pinpointer market, although Garrett is one of the oldest names in metal detecting. This handheld probe is getting some excellent reviews.  The Garrett Pro-Pointer will run you about $140.  More info at Garrett’s Website.

  • Automax Precision V4

The Automax V2/V4 has been on the market for a while.  Its long length allows the detectorist to really get into the hole to scan for elusive goodies.    Some users do report cumbersom ergonomics.  Available at Kellyco.

  • DetectorPro Pistol Probe

Great reviews on this one.  The pulse induction DetectorPro Pistol Probe has a 6 1/2 probe length and opperates on two 9v batteries.  Kind of pricey at $189.  More at DetectorPro.

  • DetectorPro UniProbe

The UniProbe is a more unusual pinpointer.  It comes paired with headphones and can be converted into a full size metal detector with the addition of a larger coil and rods.  DetectorPro reports 5-6 inches depth on coins in the hole with this PI pinpointer.  $350.  A must-see at DetectorPro.

  • “Vibra” probes

Treasure Products offers the Vibra-Probe,  Vibra-Quatic, Vibra-Tector, and Vibra-Phone.  Fully submersible, these pinpointers are pulse-induction and give vibration and/or light feedback (depending on model).  They’re priced at around $150.  See the different models at Treasure Products.

  • White’s Bullseye

A name as famous in metal detecting as White’s has to offer a top-notch pinpointer.  They do it with the Bullseye II.  This compact pinpointer opperates with sound or vibration and even has an LED to help you see your target.  Available from Whites HERE.  About $100.

  • Bounty Hunter pinpointer / Fisher F-Point

This First Texas pinpointer is easy to use with good reported ergonomics.  One of the less expensive pinpointers, it runs about $50.  Interestingly they aren’t mentioned on Fisher’s or Bounty Hunter’s website.

So do you use a metal detector pinpointer?  Have I left any good ones out?  Which pinpointer would you recommend? Comments encouraged!

A Tutorial: Finding Historic Places to Metal Detect

park_entrance

Another quickie post, but a good one.

In this post I’m going to show you how to find some good historic spots to metal detect using the Yale Peabody Museum website.

Here’s how:

1. Visit the Geographic Names Information System (GNIS) page at Yale Peabody Museum.

2. You will be given the option to enter a search term in the box. If I’m searching for schools I put “school”, if I’m searching for parks…well, you guessed it: “park”. For this tutorial I entered “school”.

3. Select your state from the dop down menu.

4. Select what kind of feature you want to search. Select the same thing you put in the search box. Check out all the features you could search.

5. Enter your county.

6. Click “SUBMIT”.

The results page will give you a long list of schools (or parks, etc). Hopefully there will be some that you weren’t aware existed, even some designated “historic”. My search for “schools” in my county revealed 29 historic schools. Your search will give GPS coordinates for the location.

So now grab your GPS, or look up the coordinates on google earth, and have fun.

Comments welcome. Did you find any possible detecting spots? Many spots designated “historic”? Any other tips for using the Yale search?

Metal Detecting Old Drive-in Theaters

drivein

Hey folks, a quickie today.

I’ve driven by this drive-in for years and never bothered to pursue permission to detect it. The place closed down in the 80’s after being open since the 50’s. I envisioned the place packed with classic Chevys, guys on dates with the friends hiding in the trunk (ok, before my time, by I’ve heard stories from my dad).

I’ve also imagined the TRASH that must be in a place like this. Old style pull-tab heaven. I’m thinking that narrow, slow sweeps, a small coil, and reduced sensitivity would be the way to go.

What’s your experience with old drive-ins? Ever detect them? Any luck? Any advice?

KNOW your Metal Detector!

Posted on September 19, 2009, 2:42 pm, by wayne and received 3 Comments ».

The Fisher F75LTD and Teknetics T2TLD have a new microprocessor and new “DSP” code with a ‘boost process’ to increase depth. Not to mention a cool camo color scheme (don’t set it down in the woods). $1200.

The White’s Spectra V3 (Vision) has a full color display and wireless headphones. $1600.

You can connect the Minelab E-Trac to your PC by using the detector’s USB interface. You’ll dish out about $1400 first.

So many expensive options, so little time.

My first detector as a grown up was a Radio Shack Discovery 2000, and I was FIRED UP about f75ltdloveusing it. Seems like everything was going good with it too – until I started researching detectors and their limitations. To prove (or disprove) what I read, I decided to plant a couple of coins in my back yard to see how the detector would respond. Needless to say there was some concern when I couldn’t get a peep from a 4” deep coin.

Then it started.

I needed another detector. Then I met my friend “The forum classifieds” The Discovery 2000 was introduced to another owner, and I made acquaintance with detector number 2. But it didn’t seem to find me any more goodies than the first one. So it had to go.

On to Detector #3, but my finds didn’t improve at all.

Detector #4 didn’t have manual ground balance. I decided I had to have that.

Detector #5 ROCKED! But the tones were confusing.

Detector #6 was supposed to get really good depth in mineralized ground. But it didn’t find me any seated coins.

I decided that I didn’t give #5 enough time, so I got another one. Results were the same.

Detector #8 was REALLY deep in my ground, but it was single tone.

Detector #9 was an “interum” detector until I had enough cash to get one I really wanted.

Thought I’d give single tone another try. Meet Detector #10.

Nope, I can’t do single tone.

Let’s offer Detector #10 for trade and see what kind of bites it gets.

Meet Detector #11.
LOVE IT!

Now, this is a basic summary of my experience with different metal detectors. I’ve changed some of the names to protect the innocent. If you’ve been metal detecting for any length of time, you can see a HUGE problem with this behavior.

I’m not LEARNING my machines.

To be a successful detectorist, you have to KNOW your machine. Every beep, iffy tone, weak tone, half tone, grunt, fart, click, pop, chatter, squeel, whistle, null, ID bounce, tone bounce, and scratch means SOMETHING. The only way to get to know your machine on this level is to get your knees dirty and dig.

Dig pulltabs. And bottle caps. And canslaw. And foil. And iron.

Keep notes about how the detector signaled that bottle cap. Was it just a beep? Or was it more of a quick, subtle nuanced buzz followed by a weak beep with a bouncing zinc/cap visual ID? Did it ID different from different angles? Did it pinpoint accurately? Did switching to all metal mode tell you more information?

Here’s my challenge to you: spend 20 hours using your detector before you give up on it and get another one. That might be a few weeks or a few months, but stick with it and try to learn what the machine is telling you.

In the mean time, I’m saving for a F75 -LTD.
