Takeaways

• 😀 The Overhauser magnetometer is a versatile, mid-range magnetometer designed for various applications such as mineral exploration, oil and gas exploration, archaeology, and military uses like UXO detection.
• 😀 The magnetometer uses a special free radical liquid mixture that allows for low power consumption, which extends battery life in the field.
• 😀 It features high sensitivity, good absolute accuracy, and high gradient tolerance, making it reliable in diverse environments.
• 😀 The setup process includes several key components: cabling, sensor, battery charger, USB converter, console, GPS antenna, shoulder strap, and extender poles.
• 😀 To configure the system, users need to initialize the GPS every time they move to a new survey area, which typically takes 10-15 minutes.
• 😀 The survey menu allows users to select the type of instrument (e.g., walking system) and set key parameters such as cycling time for measurements.
• 😀 The magnetometer can cycle up to 60 minutes, but users can adjust it to cycle at a lower frequency based on their needs.
• 😀 Pressing the 'F' button starts the magnetometer's self-tuning process, similar to how a radio tunes into a frequency, preparing it to take measurements.
• 😀 The final step in the setup is to press 'C' to start the survey and begin collecting data and measurements for analysis.
• 😀 The Overhauser magnetometer is designed for continuous operation and offers high-quality readings, essential for accurate survey results in a variety of fields.

Q & A

What is the Overhauser Magnetometer used for?

The Overhauser Magnetometer is used in a variety of Earth sciences applications, including mineral exploration, oil and gas exploration, archaeology, and UXO (unexploded ordinance) detection and characterization for military purposes.

What is unique about the Overhauser Magnetometer?

The Overhauser Magnetometer is unique because it uses a free radical mixture of liquid to energize the system, allowing for very low power consumption, which helps extend battery life in the field.

What are the main benefits of the Overhauser Magnetometer?

The Overhauser Magnetometer boasts high sensitivity, good absolute accuracy, and high gradient tolerance, making it effective for various surveying applications.

What components are included in the Overhauser Magnetometer shipping case?

The shipping case includes components such as cabling (sensor to console), the sensor itself, a battery charger, various cables for battery and USB connections, a USB to serial converter, the console, a GPS antenna, a shoulder strap, a manual, a software disc, and extender poles for height adjustment or base station use.

What is the purpose of the extender poles in the Overhauser Magnetometer system?

The extender poles allow the system to be adjusted to specific heights, or alternatively, the system can be used in a stationary mode as a base station.

How long does it take to initialize the GPS on the Overhauser Magnetometer?

Initializing the GPS can take about 10 to 15 minutes when moving to a new survey area.

What is the first step when configuring the Overhauser Magnetometer for survey operation?

The first step is to initialize the GPS, which needs to be done every time the system is moved to a new survey area.

What is the process of configuring the Overhauser Magnetometer in the survey menu?

In the survey menu, you select the type of instrument (such as the walking system), set the cycling time for the magnetometer, and then start the survey. The magnetometer tunes itself automatically before measurements begin.

How does the magnetometer 'tune' itself during setup?

The magnetometer tunes itself by adjusting to the correct frequency, much like a radio receiver tuning to a station. This process takes a couple of seconds before it is ready to take measurements.

What types of results can you expect from using the Overhauser Magnetometer?

You can expect high-quality readings and results, particularly useful for applications in mineral exploration, oil and gas exploration, archaeology, and military UXO detection.
