An Overhauser magnetometer AeroSmartMag will suit your project best - it is reasonably priced, delivers excellent performance, and does not require complex post-processing such as micro-levelling. You can obtain an anomalous magnetic field map simply by correcting for daily variations. A Cesium magnetometer AeroQuantumMag is also a good option, especially if you need data with finer spatial sampling. Please look at the overview information on our specially dedicated page: UAV or contact us and we will send you presentations where you will find even more information

The main differences are sample rates thus flying speed, heading error, dead zones and power consumption. See table for detailed explanation.

AeroQuantumMag	AeroSmartMag
Pros:
High sensitivity (export license required) High sample rate Higher flying speed - 15 m/s	No sensor orientation required, no dead zones Very low heading error, can be disregarded Lower power consumption - only two lightweight batteries are enough for a full day of operation Low and temperature-independent power consumption World’s lightest magnetometer - only 1.28 kg with battery and suspension system Does not require export permit Lower price - only 12,000 USD
Cons:
Has dead zones – the sensor has to be oriented Higher heading error Higher power consumption, and is even higher in colder weather due to required heating of the sensor (normal for all optical pumped magnetometers) 200 grams heavier than AeroSmartMag Higher price	Sensitivity is worse than that of AeroQuantumMag, but it is absolutely sufficient for most tasks and is on the same level as export versions of optical pumped magnetometers of other manufacturers Flight speed < 10 m/s - this is the speed our competitors fly with their magnetometers Sample rate up to 5 Hz = measurements every 2 m along the line, which should be enough, as lines spacing is 20-50m usually

Both magnetometers have advanced built-in GNSS receivers that allow centimeter accuracy in PPK of RAW GNSS data. This additionally requires either a separate GNSS base or our base magnetometer SmartMag or SmartQuantumMag.

Simply provide us with the drone’s mounting specifications. We can either deliver the correct mount directly or supply a ready-to-print 3D model for local production. Either way, you’ll be able to start your project smoothly and on schedule.

Advantages:

-Speed and efficiency — drones can cover survey areas much faster than ground methods.

-Access to challenging terrains — enables surveys in areas that are difficult or dangerous for ground crews (swamps, cliffs, etc.).

-Profile consistency — flight lines are easily kept straight and evenly spaced thanks to autopilot and terrain-following systems. On the ground, this is harder to achieve, especially in forested or mountainous areas.

-Cost reduction — fewer field staff and less time are required compared to ground surveys or manned aircraft.

Disadvantages:

-Increased sensor altitude — the sensor operates further above the ground than in terrestrial surveys, which naturally attenuates and smooths weak, localized anomalies.

-Limited flight time — batteries require frequent replacement or recharging.

-Sensitivity to weather — strong winds reduce flight stability and data quality.

-Regulatory restrictions — UAV flights are subject to strict national regulations in many countries.

For small areas and junior exploration projects, the setup is straightforward. All you need is:
- UAV magnetometer AeroSmartMag  https://geodevice.co/product/asm/ ,
- SmartMag base station https://geodevice.co/product/smartmag/  for diurnal correction,
- a rented drone with a pilot and a terrain-following/obstacle-avoidance system (not required if the area is flat and open),
- calm weather without wind.
With this setup, you can perform a drone-based magnetic survey, use our software to apply diurnal corrections, and produce an anomalous magnetic field map — exactly what is needed to evaluate the prospectivity of a site.
In addition, we offer the AeroSmartMag UAV magnetometer + MaxiMag walking magnetometer bundle https://geodevice.co/product/mm_asm/ , which enables both drone-based surveys and detailed ground measurements.

Not always. Terrain-following helps to keep the magnetometer at a constant height above the ground, which is especially important:
- in areas with rugged topography
- when searching for low-gradient anomalies, where even small altitude variations can “blur” the signal.
On flat terrain, or when targeting strong anomalies, terrain-following can be safely omitted.
In addition, terrain-following is not only about data quality and accuracy, but also about flight safety: accounting for elevation changes and detecting obstacles reduces the risk of collisions. We provide solutions for both terrain-following and obstacle avoidance https://geodevice.co/product/attf/ , ensuring reliable and safe surveys even in challenging environments.

To make sure the magnetometer stays intact while landing the drone please have a look at the video:
Please follow the steps described below while landing the drone:

• Slow down when assending
• Stop on the way down and allow personnel to catch the magnetometer first, before it hits the ground
• Make sure the presonnel leaves the landing pad
• Slowly decend and land on pad

Seismic and vibration monitoring is based on creation of a network of continuous long-term observations in the study area. Its field of application covers a wide range of engineering and technical tasks, such as study of regional or local seismic activity including critical facilities, diagnostics of the state of the foundation soils of buildings and structures, assessment of dynamic instability of the roadbed, determination of the percentage of building deterioration, etc.

If you task falls onder one of the mentioned categories, you should then consider the scale of your monitoring system.

Monitoring systems are fundamentally divided into two main types: the ALBEN model, designed for detection by threshold value (uses a larger number of channels) and the MASTER model, with continuous recording with smaller number of channels. In general, there is no limit to the length of the recording, only the power supply to the entire system and the communication between its components must be maintained. A set of relevant equipment consists of seismographs and, as a rule, sensors (e.g., velocimeters or accelerometers) and various accessories (software, GPS antennas, modems, etc.). The seismograph is connected to the sensor(s) and placed in any accessible location (on the ground, an element of a building structure, etc.) These recorders can then be combined into a system consisting of several pieces and the sensors can be placed around the object of study.

Surface-based seismic exploration methods often struggle with resolution loss at depth due to signal attenuation and near-surface filtering. Borehole survey, however, provides a significant advantage by placing seismic source and 3C sensor closer to the target, enhancing signal clarity and enabling precise subsurface analysis.
Our key borehole seismic solutions are designed for a wide range of geophysical studies, including:

• Seismic Logging – High-resolution imaging of the near-wellbore environment, rock density differentiation, and well condition monitoring
• Vertical Seismic Profiling (VSP) – Wave propagation analysis, velocity distribution modeling, and geological correlation
• Crosshole Seismic Testing (CST) & Tomography – Imaging of interwell space for detailed geophysical exploration

Of course. Many examples in the form of maps and charts can be found in our presentations and on our website. Contact us, and we will provide you with presentations and raw data from our numerous field tests. This way you can get familiar with our convenient data format and, most importantly, with the quality of the results.
