What is it used for?MG-200 was designed as a device for quick and efficient search for iron containing objects on depths from several centimeters to several meters. It can be used to search for meteorites, archaeological and military artifacts, communal objects (pipes, containers, armature, pot holes etc.)
What makes it better?
MG-200 is very compact
MG-200 is entirely digital.
Major advantages of gradiometer MG-200
- Filtration of metallic trash is easily set up with one button depending on how much unnecessary metallic trash the search field contains.
- Adjustable sound threshold depending on the size of anomaly. This function comes especially handy when searching large territories or difficult terrain since the device makes no sound and needs no attention until it finds the needed anomaly.
- Level of battery charge is constantly updated and charging is automatically stopped as soon as batteries are fully charged.
- Time of operation is 25 hours on 4 AA rechargeable batteries and 50 hours on 8.
- High reliability due to hard-fixed structure and absence of connecting wires and plugs.
- High stability of output by three micro-processors.

Approximate location depths for various objects
- One meter of 70-mm pipe: 2-3 meters (6-10 feet).
- Passenger car (depending on model weight): 6-12 meters (20-30 feet).
- Tank (20-30 tons): 12-20 meters (30-60 feet).
MG200 is great for locating meteorites from several centimeters to several meters. A two-kilogram meteorite can be registered at 2 meters. Right next to it the device registers over 20,000 nT.
