The Minelab NOX 800 is a high-performance metal detector that is known for its ability to discriminate between different types of metals. This makes it a popular choice for treasure hunters and prospectors who are looking for gold and other valuable metals. However, the NOX 800 can also be used to find iron, which is a common type of metal that can interfere with the detection of other metals.
There are a number of different settings that can be adjusted on the NOX 800 to improve its ability to remove iron. These settings include the discrimination level, the ground balance, and the frequency. The discrimination level determines how much iron the detector will ignore. The ground balance compensates for the natural mineralization of the ground, which can also interfere with the detection of metals. The frequency determines the depth at which the detector will search for metals.
The best settings for removing iron on the NOX 800 will vary depending on the specific conditions of the search area. However, a good starting point is to set the discrimination level to 2 or 3, the ground balance to automatic, and the frequency to 12 kHz. These settings will allow the detector to ignore most iron while still being able to detect other metals.
1. Discrimination Level
The discrimination level is one of the most important settings on the Minelab Nox 800 metal detector when it comes to removing iron. The discrimination level determines how much iron the detector will ignore. A higher discrimination level will cause the detector to ignore more iron, but it may also cause the detector to miss some good targets. A lower discrimination level will cause the detector to accept more iron, but it will also make it more likely to find good targets.
The best discrimination level for removing iron will vary depending on the specific conditions of the search area. However, a good starting point is to set the discrimination level to 2 or 3. This setting will allow the detector to ignore most iron while still being able to detect other metals.
