Kinda Cool but I'll never have one.



Cool Video Demonstrations of it here!

I have work with that device. It is simple induction balance metal detector like TM-808 that has same freq. 12,5 kHz.
It has know any location depending so that 3D is just a advert.

Hi buddies,
This Golden King named expensive and useless toy is a total scam. Here in Turkey these people (NOKTA) cheated people with their previous models NOKTA 103 and NOKTA 106 claiming they are detecting 6m, 8m, for years. And earned unbelievable money over poor treasure hunters, so pitty.
Anyways, after that, having bad name with the toys, they are almost finished in Turkish market and wanted to get rescue themselves with export. So that they started to give huge advertisings with the earned money over poor peoples' shoulders, to foreign markets.

This DPR is not a radar at all, it is a varnished version of Nokta 106 toy, with screen and a lot more useless aspects. It has gas sensor, it has lamp and so many useless show off except detecting metals  .

It is so heavy to carry on the terrain, and very very top-surface : detecting metal detector. Do not believe at all what is written on ad. is a total scam.

Here if whoever bought by getting cheated the way of their advertisings, are now selling toughly, because non of them are satisfied. And here it was lansed firstly very expensive as you are buying now. Then people came to know that is a total scam, they made half price and still nobody is buying. You guyz are buying nowadays that will survive them for a while 

have fun with the toy, they do not know even what GPR-radar means but naming as DPR, the rest you decide what might be 
Regards 

Ronin

I've been swinging a Nokta NGR in the field for 4 days. I bought it knowing it was NOT a GPR, but I figured that the 12.5kHz frequency has been good to me over the years (with 2 box detectors), so...what the heck! Here's my findings:

Bad Points
1) It is a back-breakingly heavy piece of gear and will give you much arm and back pains. I have ordered a harness, hipstick and bungee cord to help me use it.
2) A spare battery will cost USD395  plus courier fee and tax. 3rd party batteries are not recommended. A full charge will last between 3 and 4 hours. There is NO WAY i can swing it for more than 30 minutes without taking a rest due to the weight.
3) There is a slight lag in the machine when accessing the functions and menu. It is a tolerable lag though.
4) In bright sunlight, a screen hood is required. I rigged a temporary one from some cardboard.

Good points
1) Operating the machine is very easy thanks to the user interface and on-screen guides.
2) I can honestly say that it detects voids and metals up to the 2 meter mark. I have not detected objects deeper than that so far. The NGR's analysis of the metals is mostly very accurate. It was only thrown off-course in one instance (a target of 1 old sardine can, 1 unidentifable can and lid and some foil all clumped together registered as gold!)

For years each time I dig, it is with some degree of nervousness due to the possibility of unexploded WW2 ordnance. If I was a cat, I'd only have 2 lives left. Now I can see on the screen how the target lays, so I can dig down to it at the proper angle or from the side, to gingerly discover what the target really is. This is the only reason I am bothering to write all this: because this machine can help others who explore similar places where such dangers are present. After the first 2 days of using the NGR, I have become confident in its abilities, and can trust it to a great degree; this does not mean I will dig without exercising the usual due caution.

Am I happy with the machine, overall? YES, I am very happy despite its huge weight. I guess I better add a disclaimer that I am not selling any metal detectors nor am I attempting to promote the machine. Please do not ask me if I have found anything valuable with the NGR because I will never answer that. I will venture to say that the Nokta Golden King is a partial scam, because of it's claim to be a GPR. I do not know if the general search head will really detect down to 15 feet. Other than that (and the heavy weight) I find it to be a worthwhile investment.

hi..      

Linkback: http://thunting.com/smf/index.php/topic,4854.msg36446.html#msg36446

Hello to Airoia and Silver79. I shall try to answer your questions as best as I can.

Ferrous discrimination: It only has 2 modes, on and off. Most of the time I have searched with the discrimination in the OFF position (my main rule is to dig every target detected). I tried it with the ON mode in a trashy area and it did not pick up any cans/pulltabs/nails, so I can say it works well.

Soils and rocks: I used the NGR for 4 days in an area that has the worst soil I have ever seen around here. It ranges from reddish acidic (pH is 3.9 to 4.6) tropical oxisol with very high presence of iron (tested with Lamotte soil testing kit and the content is off the scale) and clay content (30%-60% w/w) to a mixture of colluvium and riverine alluvium that is also liberally laced with iron and aluminum. Heavy metal poisoning leading to premature senescence/poor root growth of crops is common, and even the hardiest of weeds like imperata cylindrica and mikania micranthum/cordata grow poorly there. I have an agriculture background and am very familiar with local soils/vegetation. The NGR punched thru those soils with ease, and I was relieved. For comparison purposes, the honest salesman from Mala Geosciences (they make real GPR units that are very expensive) told me that their machine in this particular area could only get less than 1 meter of penetration due to the soil characteristic. The 2 meters depth I have gotten so far with the NGR makes me happy.

With regards to hot rocks, I encountered 6 or 8 (I forget the exact number) spots where the unit went off, and analysis showed ferrous metal at zero cm. It was just small surface rocks that had some iron ore in them. The on-board user guide states that the unit is also capable of penetrating rock, but it must be ground-balanced on the rock first. I stood on large rocks with certain carvings on them, balanced the unit and nothing was detected. A Hitachi EX120 Landy was used to remove the rocks and nothing was detected under the rocks or in the rocks (after they were broken up). Until I encounter a target in or under large rocks, the workability of this feature is still uncertain.

Coil type: The NGR is the model that comes with the general detection head rated to go down to 5 meters.

Size of metal detected: At slightly over 2m (I forget the exact figure...I think it was 210cm or 206cm), the target was approx 15cm square and 8cm tall. The depth analysis of the NGR is amazingly accurate, but you must properly ground-balance it, and sweep slowly and smoothly at a constant height for more accurate results. I worked the unit with the accelerometer function OFF because in some places, I had to be lowered with a rope to detect on near-vertical drops, and I feared the accelerometer would bias the detection results.

Weight of the unit: I estimate the weight of the box with screen to be 2.5 to 3kg, the rod and general detection head also weighs about the same, so it's about 5kg. My neck, right arm and back are still aching as I type this. One day I will weigh the unit on a scale.

How quick is the unit: I do not really understand this question. If you are referring to recovery speed, I did not test for that. It takes some time to boot up, and it is impossible for me to move quickly while wearing the box on my neck and holding the wand.

If you have more questions, feel free to ask, and I shall reply whenever I am back in town. If this machine helps just one person avoid an unexploded grenade or land mine, then I consider all this typing to be worthwhile.

Hello to uksearcher, and congratulations on your find! I am waiting for my bungee, hipstick and harness to arrive from the USA within the next 10 days or so, and shall report on if such a rig can help alleviate the weight of the rod and detection head. If the weight can be distributed to other parts of the body, detecting with the Nokta will be much more enjoyable.

Since the Nokta Golden King claims to be able to detect non-metal objects as well, I am going to see if it can find chunks of amber and copal in the ground. I read somewhere online that it uses soil-displacement algorithms. Maybe the machine has to be de-tuned in manual ground balance mode for this purpose. If any other users care to experiment, please let me know your settings and results. I suspect that IF it can detect amber chunks, they will show up as blue voids on the screen.
