Use headphones will increase battery life, increase privacy, and increase their ability to hear weak signals clearly in a lot of background noise. They offer benefits even for those with excellent hearing. Clear sound is usually more important than the specs on the width of the frequency. In most cases, higher impedance headphones (100 ohms) offer sharper sounds. There are special headphones to 300 detectors ohms and 600 ohms. The common market headphones are 32 ohms range
As a general rule, the lower frequency detectors offer better sensitivity to copper and silver and better depth of General detection and rejection of garbage. The most commonly used models operate at lower frequencies
higher frequency detectors are more sensitive to small metals and natural gold. However, they have difficulties with the discrimination of non-ferrous objects. But, are good on discrimination of small pieces of iron. So that most of the detectors to prospect discriminate only what is iron and non iron, because most metals found in garbage on prospecting are nails, arestes, thumbtacks and tractor blades fragments which are easy to be broken down. Their sensitivity to small metals makes it tedious to use around garbage areas as examples, beaches. Most of the gold prospecting detectors operate at higher frequencies. Because they are best for detecting the fragments of gold and in your region there is no garbage considered to be on a beach
There are good places to hunt
No one can do anything. Just because an area was hunted before doesn’t mean a person with patience and a modern detector can’t even find the “good stuff” anywhere. The investigation can still turn up in places like has never been surveyed research. Experience is a good ally, but also seasonal changes as storms, sighs of freezing and erosion can also renew areas-particularly beaches where the surf is a constant source of new targets. This also happens in the regions where the gold detector not reaching a certain layer of Earth before, but with the pass the time nature will removing these layers of Earth, facilitating the discovery of new gold supplies in the same place that was considered finished famous trails metal detector.
