My homebrew PI detector and some finds

[Rob in KS]

I finally got it finished enough to take it for a test drive. I built it for large deep targets like a cache or meteorite. As I pushed it across the yard, I could hear lots of small targets go by. When I got to this spot I could tell it was a bunch of "little" targets in a small area. This thing doesn't see things as small as pulltabs and bits of wire. Here is what I found:

Yesterday I went out again, got a pretty solid hit. 4 hinges within a 5 foot area. It sounded like a single larger target.

Air test show a beer can at 2 feet and a top of a 55gal drum at 5 feet.

Rob,

That is one neat looking detector. I'm betting your gonna have some fun with that puppy. Why don't you bring it down here to North Central Oklahoma, and we'll see what we can find.

Hope you find some great finds with it.

Nice photos and homemade machine, this is a great way to get a quick look at an archaeological site. I like how you did the photos quite interesting. I want to make a GPR unit, I have seen these used on digs, but right now beyond my skill level to build. PS - the parts look kind of like burner covers you find on a gas grill or even parts of an old coal furnace, the one I ripped out of my old house were cast iron though. Great post!

I am impressed

Fun looking rig you built there Rob!

I still remember the grand old days when KnightKit and HeathKit made all those easy to assemble kits.

Back about 2 years ago I tried hard to get someone to offer a complete PI kit that anyone could build but I was unsuccessful.

Happy hunting.

Back about 2 years ago I tried hard to get someone to offer a complete PI kit that anyone could build but I was unsuccessful.

Those guys at Heathkit were REALLY good. Its hard enough to design a circuit. Even harder to made it repeatable. Even harder still to write up the directions. And to get it to the point where almost anyone can build it .... wow. Oh and you could learn electronics while you built it.

I would say that most people who try to build this have some problem getting it to work (I did). I finally did get it and now I'm having problems getting the second one to work.

I've been pushing it around some.

hey Nashoba,
Thats how I got started in all this. It took a lot of research to find out how he did it. He found several pieces. He started out driving a 1986 minivan, now he drives a Hummer. The big one he found is valued at a million. I think he sold a basketball sized one for $80,000

His coil is 12 by 8 feet !!!!

Well I see you are in that neighborhood...Maybe one day you can show me a pic of you and your new Hummer!
I wish you the greatest of luck in finding that million dollar meteor. I know they are there...I saw it too!!!

Hmmm, lets see ... get a Hummer or pay off the mortgage ? ??
Decisions,decisions

I just bought a new SUV this past fall. I looked at the smaller Hummer for about the same price, but the Hummer was so underpowered it was a clunker to drive. I wound up with a Dodge Durango with all time 4wd and lock in 4wd and low range 4wd. And I got me a Hemi to boot! But it's much too pretty to take off road! LOL A tradeoff I guess? Now I'm like that guy in the TV commercial that braggs about all his things he owns but confesses, "I'm up to my eyeballs in debt!" M nty

Good luck Rob, I hope you find a big space rock worth about 6 figures! Tsgman

Hey Rob that is a great looking hinge finder, but can it pin point?

LOL.

Nice job on the new rig.

hey bring that thing to denver all the stuff here is deep i have trouble pulling out stuff even with the hot head coil

Lads, unless I dig up a burried vault of gold, that I find using one of those geophysics detectors, I'm stuck with my 1.4l car. Petrol is about $7.00/gallon here, and I drive 70 miles round trip to work.

Anyway, that's an awesome detector, and I can't help but think how great it would work on all the plowed farm fields around here. I'm going to check out the pland. Thanks for posting that, and happy hunting!

 

[Rob in KS]

Of course I was kidding about the Hummer. I'd pay off the farm in a heartbeat. I know that gas prices in the U.S. will only go up. WOW, $7 / gal. I want an electric car and a wind generator.

This PI has proved to be a relic magnet. I can really cover a lot of ground in a short time. It can see deep enough to get the targets in the top foot or two. I can ignore the smaller targets. In a month or so they will cut my hay field, and I'll have about 20 acres to play in. When they built one of the larger sheds, they leveled the area taking the extra dirt out into the hay field, spreading pieces of iron around a several acre area. I'll have July and August to cover that.

In September, the farmers will be getting the land ready to plant wheat. Then I'll have about a month before they plant. I plan to cover as much as I can. Then in October they will take the cattle off of the pastures. The grass will be eaten down. I've got 27 acres of pasture and access to 160 acres next door.

Now if I could just find something interesting !!

I just saw something along these lines being pulled by a four wheeler for meteorites in Kansas. It was on the show "Cash and treasures", and they did, in fact, find two huge chunks of a meteorite. Great job on making your own!!!

~Nash~

I also saw that show!! Talk about a find! Those things are worth some big bucks!
I will keep my fingers crossed for ya!

That's the kind of detector my partner and I have been talking about building. I know the guy sells the board, but does he have any kind of instructions or information that comes with the board? When I was a kid, my dad built an 8' coil to locate boat motors on the bottom of the lake. They never did get the kinks worked out, every time they would try and tow it behind the boat it would nose dive to the bottom. They just couldn't get it to tow at the desired depth. What size wire and what uH is your coil? You can email me if you want. I really like what you built and want to make something similar. Can't wait to hear you struck it big!

Hey, Rob...NICE...SWEEEEETTTT. I saw Burdie's post....are you going to bring it to CTH?

that would work good for finding large Gold nuggets. The guy who found the biggest single gold nugget had something like this rigged on the front of a jeep and would drive around the desert all day. His ideal was that he could cover more gound which would allow him to focus on the big stuff. It worked!!!!

I'm playing the law of averages too. If I cover enough ground, I'm bound to find something interesting. Not many gold nuggets in Kansas, just scrap iron

Hey, Rob...NICE...SWEEEEETTTT. I saw Burdie's post....are you going to bring it to CTH?

Yup, I'm bringing it. Gonna vacuum up all them prizes.
