Chinavasion Metal Detector

[Kenny]

Hi Steve, please I need your advise on the detetctor that I just ordered from China, Nugget 9.5inch, waterproof coil with 9.6khz. Its sold by Chinavasion. I actually ordered before getting to know about this site of yours and as someone with little or no knowledge about the detetctor, I go for something cheap and also with a reasonable depth. The depth of this machine is 3.5m. I am writing this because I could still cancel the order if I know it won't be functional. I also noticed yesterday that most of the detectors from US give 5yrs warranty while this one gave just 1yr warranty. Please kindly advise. Anybody else could give helpful hints. I will also like to know what the FREQUENCY rating means to a detetctor. Thanks

Sorry, I forgot to mention to you that I am in South Africa but I intend to use the detection in the south-western part of Nigeria.

I would cancel the order immediately. If this is a 9.6 kHz detector with a 9.5" coil and they are quoting depth to 3.5 meters than I do not trust the company. That is a pretty outrageous claim. Detectors like that find coin size targets down to a foot at the very most and larger items at 2-3 feet at most. Better to be safe and do more research - you can always reorder later.

What are you going to use the detector for?

Frequency is a basic factor in determining the performance of a VLF metal detector. Under 10 kHz are normally coin detectors. 10 - 19 kHz are "do-it-all" detectors. Over 20 kHz are dedicated gold nugget detectors.

Multi-frequency units are good for most anything except prospecting. They are the best choice for salt water.

These are generalities only, not carved in stone. Gold nuggets have been found with multi-frequency detectors and coins with 50 kHz prospecting machines.

The advice you seek should come from someone who owns one of these detectors.  Do you know anyone that owns one?

 

Where did you get the number of 3.5m?

Thanks Steve for the candid advise. The analysis on the impact of frequency on the metal target and efficiency really made my day. I believe that I am informed enough to look for a functional detector. I actually intend to start a small scale mining and really need to use the detector to know where the gold really is instead of just digging anywhere in the name of mining. At the same time, I will be using the detector to find nuggets around same place because the location is believed to have huge gold deposit but it is highly unexplored as well. Please don't hesitate to give me any additional information that you know will help my new found love. Thanks so much again Steve

Mn90403, thank you so much. I do not know anyone that owns the detector. A friend that has been involvd in prospecting is the one that advise me that I can get just any detector.

Kenny,did you pm everyone here this same question,or just me?? Dude,look at the name "Chinavision" that should be enough to make your decision.

 Kenny;

  I'm sure everyone here truly wishes you the best of luck, but when it comes to mining you have to create your own luck. Your taking a big enough chance going into mining so don't add to the gamble with an unproven detector- definitely not one making unrealistic claims from China.

 Steve has done a fantastic job archiving information on this forum and it will be invaluable for the detecting part of your operations.

Keep us informed on your progress.
