There are a lot of interesting things going on under your feet. It is possible that a million tiny earthquakes are taking place that go undetected because they are so small. If you have the right hand held equipment, you may be able to record them as they happen. Anyone who lives in an area that is prone to seismic activity needs to have the means to discover any potential quakes before they happen.
Do you have a hunch that there may be elements and other raw materials under your land? If so, an element detector can show you what exactly you have under your land. You can also benefit from metal detectors that can find gold, tin and other metals that could be worth hundreds or thousands of dollars.
Buying a geophysical instrument at AGI can save you a lot of money. Those who don’t want to buy brand new equipment can buy used equipment that will work just as well as a new piece of equipment would. Whether you are a professional geologist or an amateur who likes to poke around under the ground, you are going to have the right tools to find out exactly what is going on underground.
