After researching the OKM EXP 4000 and some of the other products they carry, I still cant come to a conclusion on if I want to purchase th exp or something may be more "reliable" such as the minelab 4500. Im searching in areas with lots of minerals and not that much trash. Im lookin in depths of 10-30 ft deep, and looking for larger sized treasures. Im not really doubting the capability of each of the machines I just want to make sure the okm is reliable. or should I just spend less money for something thats not as advanced but works better?

Hey there,

In regards to OKM and mineralized soil, please let it be known that the OKM capabilities are greatly compromised in highly mineralized soil.

Identifying targets using the OKM equipment

I just received another E-Mail from a new user of the OKM equipment. When you are locating an object there are some primary rules that you need to follow.

1. Do not turn or rotate the equipment. Please keep it facing the same direction as when it starts.
2. Practice with the equipment on known targets so that you familiarize yourself with it and know the ins and outs. This goes for all equipment regardless of what it is.
--- The OKM equipment will find cavities, faults and other fracture zones in the ground.
3. With their software don't be deceived by a red spot on the software unless there is a hole (blue area) right next to it. Non-ferrous metals act as an amplifier so an old tin can may become your target.
4. Make sure your battery(ies) are charged. The number one reason for equipment failure are uncharged or weak batteries.

The OKM Rover C that I have is from 2003 and has operated without a flaw. The best way to determine if it is right for you is to either visit a dealer, or find someone local who understands the equipment to show you. There have been a lot of finds with the OKM equipment. I personally have had a couple and there are a lot of people with a lot of testimonials. But in regards to reliability, I have been problem free.

One question, are you looking for natural treasure or buried treasure???

A friend of mine bought the OKM EXP 4000 and when we use a 1 meter vertical antenna on a known target (aluminum wheel from a car) buried at 1.5 meters, the results are inconsistent.During the test run and after downloading the image to the visualizer program it shows a red spot at the 11-th impulse mark altough we know it should be at the 9-th. Is it possible that we are not even detecting the wheel and there is something else at the 11-th impulse mark?
Also if somebody has experience with this unit I'm curious to know what kind of metal targets they have been able to detect and at what depth. And also if it can locate tunnels.
He asked me to find out as much as possible about this unit and I'd hate to be the one telling him that he spent 30,000 Euro for this piece of crap....

Have your friend contact me directly [email protected] so that I can assisst him. There can possibly be something at the 11th pulse. If there is a ferrous object nearby a non-ferrous object the ferrous object will take precedence. The non-ferrous object may still be showing, just not as strong because it is being masked.

Last weekend we had a possible find and right now we are waiting for the weather to clear to make a positive id on what it is.



Also have your friend send me the scans *.v3d so that I can assist him even more.

I had tried the OKM Exp4000 and came up with
the following observations: (these were my personal observations and i have no intention to destroy the refutation of OKM/ )
1. It cant give an accurate depth measurement. We detected a target at 7 meters and yet when we reached 7m, the target is not there.
2. The signal tends to spread out as it gets through the soil layers. The located target is not directly under the area detected.
3. The target buried in layers of chromite cannot be detected/discriminated.

Hello Kaloy,

The depth is calculated off of the input soil. Unfortunately, with different soil conditions it is very difficult to give an accurate depth. Personally I don't use that data.

Questions for you.

Were you able to repeat the scan and hit the target every time?
Did you cross the target from varying compass headings, ie from the North, East, West, South?

Can you please send me the files and I will gladly analyze them for you.

kaloy , SEVEN METERS? You must be really pissed. I've seen people dig 9 meters in granite because a "electroscope"LRL" pointed there...

That is why I make sure there are a lot of scans before digging.

Re: OKM?? money down the drain

I sent cassbiz 5 OKM scans from 5 totally different locations. This is the professional response that I got:

Hello HiiiQ,

I was able to take a look at the scans and they look most impressive from the surface.

As I analyzed the scans, it appears that there is a fair amount of ground water in the area. Also the most prominent target is on the ground but not deep. As a matter of fact it almost appears to be on the surface or right below it.

When the signal strength is very strong there are a couple of indications that need to be taken into consideration.

1. Is there a ground fault that was traversed? If so, then is it at one point or does it continue on in a linear path?

2. Is there a well or air shaft? A well and an airshaft from a mine will almost appear exactly the same from the initial first scan. Whereas an airshaft usually can be differentiated by locating a mine shaft or tunnel in the vicinity. Best guess when such a strong signal is realized is to take a metal detector over the target area and see if there is a hit there. In the event that excavation seems to be the way to go, as soon as the first 20~30cm of topsoil is removed, perform another scan. Is your target still there?

3. Is it surface trash? This is by far the most frustrating. The signal is so strong that you think you are on top of something big. A standard metal detector will help you to determine if it is surface trash. The eXp 4000 has a metal detector accessory or just a standard separate one will also work. For the most part you are only looking from 0~20 cm deep.

All in all, like I mentioned earlier, real targets don't move. This appears to be a real target unfortunately it may be surface trash and I would scan the area with a metal detector to verify that it is or isn't before putting a lot of effort into it.

Hope this helps,

Is that total nonsense or am I crazy? I tried to explain to my friend that he bought a worthless piece of crap and he doesn't believe me because it is so "expensive".
I taught GOLDEN KING PLUS is crap but it is at least based on real technology and can equal or exceed the performance of a $200 Bounty Hunter.
OKM is a low grade magnetometer with software that creates some fancy worthless pictures. Don't forget that it comes from the same company that makes the BIONIC long-range locator. A couple of friends have it but I don't even want to discuss it.....
Correct me if I'm wrong.

I will. Yes we repeat the scan and get the same results.

From A real user of the okm gems unit with super sensor

Hi to all
I thought that it would be of interest to share my experiences using the okm equipment, like others out there i also wanted to believe the claims made by this company, but would I fork out so much money for something that just did not do what it said?
for me I was not interested in finding metallic items at depth, my sole concern was the capabilities for finding voids, i was searching for ancient tombs cut into the rock, these can be anything from 1.5meters wide and 2meters in length they are normally found at depths from 1.5meters to 8meters, I purchased the gems unit with the super sensor which was over £2500 just for the sensor, I must admit if you are to buy this equipment it helps to have someone to show you how to use it and to explain what the actual visualizer 3d graphics are showing you in the scanned area, unfortunately for me I had to learn the whole thing with no instruction, and talking about instructions, the manual is pretty useless and does not explain things clear enough, now on to using the gems unit, at first I thought the best thing to do would be to scan an area of 5m x 5m on top of a known tomb (void) and see what the scan would show, well my first attempt was very unclear as voids or cavities are suppose to show up blue unfortunately for me this was not the case as the scan was showing lines of blue here and there and nothing like the clear scan pics you see on the okm website, at first I thought id been scammed, but it was my inexperience of not knowing how to use the graphics program that was causing me to give up with the machine, unless you are prepared to fully understand and use all the features that help you get the correct scan ie interpolation feature which is a must on this unit if you want clear scans.
what is not so clear, maybe someone on this site can help on this is that all the scans that I have done show maximun depths of up to 5m now this is concerning as the unit is suppose to scan up to depths of 25m I have looked at all of the example scans by okm and not one of them is over 5m why is this? makes you wonder, my experience of using the okm stuff is that it will find voids but you must be able to interpret the readings otherwise its not easy I will enclose a scan of what I was asked to do by a local villager the story goes that before the war the local village people placed all there gold in an iron bucket and buried it in the cellar of this Lady's old house then they all fled , hoping to come back some day to retrieve it unfortunately for the village people 35 years had passed and now with the war over the lady of the house came looking for the place where here house had been ,unfortunately the house had been demolished and now a road was built over it now me being a bit sceptical regarding this story thought ok point me to where you remember the house to be and ill scan that area , well to my surprise I got a shock! as the scan showed the exact spot of the bucket and the depth it shows clearly the hole with the bucket located inside in red check out the scan u

OKM

Hi gooch. Have you ever noticed that 100% of the scans with the OKM have at least one red and one blue spot in them? The software is simply amplifying the points with highest and lowest magnetic response. By nature this magnetometer can not ever detect non-ferrous targets. Also by cassbiz's oun admission the depth readings are arbitrary and have no meaning. For the money you payed you get a 2-D picture of surface mineralization. If it's a bucket you want to locate I'd recommend White's TM-600 or TM-808 or Discovery TF-900 Good luck!

Re: OKM

hi
you are correct, most scans do show a red spot, this is what I was trying to explain when I was saying that you really need to understand how to interpret, what the scan is showing you, what the company does not tell potential buyers, is that when you scan an area, they make it look like you don't have to do anything else, it should all be clear, unfortunately this is not the case as you must use interpolation at least 3 times otherwise you cant make out what the graphic is showing, what I must say is that I someone is to buy the okm units in hope of finding non ferrous items then id stay away as its capabilities are ferrous, for what i purchased the gems unit to find voids, holes in the rock, I am pleased with the outcome of doing just that but must admit, you must scan the area three times before digging as the scans are not always consistant.
I guess its far more easier to see voids (blue area) than for actual treasure, which happen to be small in comparison.
I still have not received an answer to why all the scans from okm are showing no more than 5m, I may ask cassbiz.
by the way what experience have you had using there machines and if so what machine do you have?
thanks for replying

OKM

GEMS Gradiometer
Cat# 1158-3080
$6,598.00
Demonstration by Appointment Only!
Please e-mail one of our GPR specialists to set up an appointment:

Wikipedia: A gradiometer measures the gradient (numerical rate of change) of a physical quantity, such as a magnetic field or gravity.[1]
1. Axial gradiometer. Such a device consists of two magnetometers placed in series (i.e. one above the other). The result coming from the device is the difference in magnetic flux at that point in space (a.k.a. first spatial derivative).
2. Planar gradiometer. Such a device consists of two magnetometers placed next to each other. The result coming from the device is the difference in flux between the two loops.

OKM claims:
The Super Sensor is a specialized antenna which offers professional metal detection features. Small metallic targets such as gold nuggets, coins, rings, jewelry and other valuable metallic objects hidden under the ground can be located easily with this antenna. Also it is very suitable to detect larger objects like boxes, bunkers, pipes, chests, gold or silver bars and other metallic masses which are buried deep under the surface or which are difficult to locate with standard GPR antennas.

Those claims are an insult to my intellect.
