Metal detectors. Answered

Ok so I want to get a metal detector. But i don't want to spend a fortune but don't want to spend $10 for a stinky one. I'm looking for one for around $50. I just want to look around my yard,and see if theres anything interesting (once i found a little diamond or some kind of rock).


i want to make a metal detector using tda0161, when the detector detects the metal from a specific distance the buzzer sounds but as the metal comes near and near the buzzer sound increases!!

so anyone guide me for this

Saw an article to make one with an arduino, Then there is the old radio calculator trick. Some peoiple have made them with an 555 ice circuit.. you can make them a lot cheaper than what they sell for in the store just have to do a google search. http://www.electroniccircuitsdesign.com/sensors/tda0161-metal-detector-electronic-schematic.htm

It seems you are looking for a cheap metal detector since you regard metal detecting as your new hobby. Well, $50 cannot buy a metal detector, maybe a body scanner.

I got a bounty hunter junior from goodwill for 10$. I was gonna look for an instructable to possibly make it more powerful or something, but found this post and was surprised to learn that it was any good. lol.
...now, what i really need to do is possibly make it extend farther.
Being 6'3 im not exactly junior size and not bout to ruin muh spine.. ;3

What you want is a Bounty Hunter metal detector, I have a few of them. The one you want you can find on ebay for under $100.00, its the Tracker IV, it's not a deep machine, but will find anything metal up to 5 or 6 inches under the ground. My son just found a 1881 Indian Head penny with it. It's a good machine for the money it costs. if you find a couple of forums that talk about the tracker IV you will see that its a great machine. here is the link to the detector from Bounty Hunter. <br /><br />http://www.detecting.com/products/product.cmdl?c=8166fcf29a1111d4<br /><br />Oh not to sound really rude but that one from amazon is not a good machine, its junk, check out the tracker IV it wont steer you wrong nor would I. hope you like it.<br /><br />

I built my own years ago. The hardest part for me was getting the "coil loop" or feedback loop properly wound and making my own Faraday shield properly (I wasn't very old at the time). I threw together a little circuit, very similar to the one at EDN: Circuit for Metal detector

Yeah, mine was good for finding nails (and therefor studs, pipes, and electrical wires) in walls though :-)

Well my yard may be full of stuff mainly old stuff because my house is like 250 years old.

I understand. You need something that will work fairly well, without the hassle of trouble-shooting it. I just did it to learn more about comparator IC's and inductance.

I made a lot of my own test equipment back then, but try as I might, I had trouble with an Inductance meter and a Capacitance meter (and I put together quite a few "probes" for my analog Oscilloscope, too). *shrug*

Sorry I just didn't know what your talking about. I don't know allot about electronics and stuff.

No need to be sorry. You can't be versed in everything :-)

We all have different strengths and weaknesses.

As for me, I think I have too many "things" flying around in my head sometimes....makes concentrating hard ;-)

Here in Indiana, we have Big Lots stores that basically sell after market overstock on the cheap. I saw a $40 metal detector there, but didn't have time to stop and read the specs. I want one too. I was wondering how close the circuitry is between a stud finder and a metal detector.

Cool! I have always wanted a metal detector too!!!!

If you have a PayPal account, you have some protection.

Ya, my dad does but what i meant is you never know what kind of shape it's in or even if it works.
