Where to buy?
If you already have such as knowledge of the satellite navigation system, you can start to do something.At the very beginning is probably the best one to buy such a device, so the GPS. The price of such "toys" ranging from several hundred to several thousand gold. We know that this is dependent on what quality equipment is chosen. Is the same as for example with computers, you can buy a computer for a few hundred gold, so do domestic work only, but you can also buy some, a few thousand, for (using the language of youth) intended primarily to games and plays. The same is true with GPS, here, some people pay well over several thousand gold to boast that their stand on it. I think that good equipment, if someone does not need GPS at work, in life, you can easily purchase price within the limits of a thousand gold. Correct equipment you can buy on the Internet, or the respective stores' ground '. If someone does not know at this, it is better to always make a professional opinion. You can also ask the people that sell the equipment on the Internet, since they sell it, to some degree should also be familiar with it. We know also that buying cheap does not pay us for this very much. Although it is quite strange, but it is a saying that "at low cost to expensive, so the device can quickly break us, which we certainly did not want.Finally, I wanted to point out that a very strange situation for me is to buy the GPS navigation for cars, whose total value is less than the equipment ... Can Imagine a situation when you see it in the ordinary Fiat 126p, satellite navigation system? I personally do not and for me it is a utopia ...
