XP Gold Maxx detector

[deepdiger60]

I have a question ? why is it not legal to own a XP Gold Maxx metal detector in this counrty USA i try to order one from the UK yesterday and got a reply saying the machine is too powerful to run in this country it has wireless head phones that would mess up radio commuications no mater where it was used ?? and even if i did get one shipped Customs would hold it and i would lose it , it is one of the best detectors out there on the market now it can get as deep as 18 inches no problem on a target as small as a pea the Brits rave about it in the fields finding small Roman silver n gold coins , i just dont understand why a detector can mess up radio signals ?? Thanks on any insight Jim oh if i cant get one then what is a machine thats even close to that ? i have a DFX now it works just fine but i wanted a second machine that goes deeper

....it would not pass the stringent rules that the FCC places on devices that can transmit. Because of that it probably cannot get approval from the FCC as an item that can be sold in the U.S.
Without really knowing all the details, that is simply my guess on the matter.

we are not talking about a high tech radio commuication devise just a pair of head phones that can transmit a short distance to other XP Maxx detectors the same thing Whites has now ok thanks for the help HH Jim

Remember you asked......

Frequency spectrum allocations are different in different regions of the world. Transmissions in one frequency range that are acceptable in one country will not be authorized in another country. Broadcast transmissions that are allowed in one country tend to trump the ability of, say a headset, from transmitting within that same frequency sprectrum that is in another country. That unlicensed transmission can be considered as interference to the licensed operation within that bandwidth.

The actual power, while minimal, could be out of tolerances within the US confines in that particular frequency spectrum. Something as simple as 5 watts of power could require a license to operate within that frequency band. (A good example would be the citizens band spectrum that required a license to operate for many years before it was deregulated.)

If that headset is transmitting within (and I have no idea) the cellular phone spectrum, there is no way it will be licensed to operate within the US due to the operations that are already taking place in that spectrum range. It could also be transmitting within the Amateur Radio spectrum. If that is the case, it must be licensed in order to be used and it will have to have additional circuitry installed to ensure that it will not interfere with operations within that spectrum.

These are just a few examples where a simple wireless headset causes problems that need to be rectified prior to its use in the US. If you really want to know more about RF devices, go here http://www.arrl.org/tis/info/part15.html It may not tell you all you want to know but it may provide a beginning of an insight as to why the detector and its headsets are not allowed to operate within the US boarders.
