Geometrics MagArrow II UAV-Enabled Magnetometer
The MagArrow II is the second generation of Geometrics’ best-selling UAS-deployable magnetometer, setting a new standard for drone-borne magnetic surveys. A laser-pumped cesium-vapor (Cs133, non-radioactive) total-field scalar magnetometer in a 1 kg aerodynamic carbon-fibre shell, it carries its own MFAM™ dual-sensor array, GPS, IMU and Wi-Fi — so it works independently of the drone and its software.
UAV Magnetometry — Introduction to the MagArrow

UAS-agnostic — fly it on the drone you already own
The MagArrow II attaches easily to most enterprise UAVs and is fully self-contained — GPS, 32 GB storage and Wi-Fi are all on board, with no data connection to the aircraft required. Survey lines are flown from your preferred UAS software while the magnetometer logs independently.

Dual MFAM™ cesium sensors — no dead zones, no drop-outs
Two high-performance cesium sensors are combined so that whenever one approaches its dead zone the other is optimally oriented. The result is reliable, high-quality total-field data in any sensor orientation, with a heading error of only ±5 nT across full 360° spins.

1000 Hz sampling — survey faster, filter motor noise
A GPS-synchronised 1000 Hz sample rate lets you fly surveys at up to 10 m/s while still collecting a reading roughly every centimetre, and makes it easy to filter out UAV motor noise. Two hours of hot-swappable battery life outlasts multiple drone flights.
Typical Uses
The MagArrow II excels wherever ground or piloted surveys are slow, costly or unsafe: environmental (locating abandoned wells, pipes and storage tanks), UXO detection and delineation, archaeology (non-invasive site mapping over large areas), geology and mineral exploration (regional magnetic-field variation), and inaccessible terrain such as wetlands, heavy vegetation and protected land.
Service & Warranty
Every MagArrow II supplied by GulfNet Emirates Drone & Robotic Systems includes the manufacturer’s 1-year warranty, carrying case, AC power adapter and USB drive with the operation manual and software. The cesium-vapor magnetometer is export-controlled (US ECCN 6A006); our Dubai-based team manages the export-licence process and provides survey-planning advice, compensation-flight guidance, Survey Manager onboarding and regional technical support across the UAE and wider GCC.

Frequently Asked Questions
Where can I buy the Geometrics MagArrow II in Dubai?
The Geometrics MagArrow II UAV-Enabled Magnetometer is available in Dubai through GulfNet Emirates Drone & Robotic Systems. Orders and quotations are handled directly by the Dubai-based team, who also coordinate the US export licence required for cesium-vapor magnetometers under ECCN 6A006. Buyers in the UAE can request a quote through the product listing on the GulfNet Emirates DRS store, and the response includes local pricing in AED, current stock position, accessory options, and the estimated timeline for export clearance. The team also advises on drone compatibility and survey planning, so the MagArrow II arrives ready to integrate with the enterprise UAV already in service.
How much does the Geometrics MagArrow II cost in the UAE?
Pricing for the Geometrics MagArrow II UAV-Enabled Magnetometer in the UAE is issued on request rather than published on the storefront, because each order is quoted against current AED exchange rates, accessory selection, and the US export-licence process attached to cesium-vapor instruments. To get a firm Geometrics MagArrow II UAV-Enabled Magnetometer price, submit the Request a Quote form on the product listing. GulfNet Emirates DRS replies with a confirmed AED figure, delivery lead time, warranty coverage, and any recommended add-ons such as non-magnetic suspension cable or a spare battery set. The quote also outlines the export documentation buyers need to prepare for UAE customs.
Who is the authorised Geometrics dealer in Dubai and the UAE?
GulfNet Emirates operates as an authorised Geometrics dealer Dubai buyers can approach for the MagArrow II and related geophysical instruments. As a Geometrics dealer UAE customers rely on for enterprise procurement, the company handles the full purchase cycle from initial specification through export licensing, delivery, and regional after-sales support. Working with a formally recognised Geometrics distributor UAE means the hardware ships with the manufacturer’s original warranty intact, the correct ECCN 6A006 paperwork, and access to Survey Manager onboarding. It also gives geophysics teams a local point of contact in the same time zone rather than routing every technical query back to the United States.
Is the Geometrics MagArrow II available in the UAE right now?
Yes, the Geometrics MagArrow II UAV-Enabled Magnetometer is offered for sale in the UAE through GulfNet Emirates DRS, with stock status shown as in-stock on the product listing. Because the instrument is US export-controlled, actual dispatch depends on the export licence being approved for the destination, and this step is managed by the Dubai team as part of the order. Survey firms, defence integrators, and geophysical consultancies looking for a Geometrics MagArrow II UAV-Enabled Magnetometer for sale in the region should raise a quote request early so licence lead time is factored into project schedules. Availability for Saudi Arabia and other GCC markets is confirmed at the quotation stage.
Which drones is the MagArrow II compatible with for magnetic surveys?
The MagArrow II is UAS-agnostic and mounts to most enterprise UAVs, since it carries its own GPS, IMU, 32 GB storage, and Wi-Fi and does not need a data link to the aircraft. At 1.2 kg without batteries it has limited impact on the endurance of a typical 3 to 5 kg payload-class drone, and it is normally suspended on a non-magnetic cable so the airframe’s magnetic signature stays clear of the sensor. Survey lines are flown from the operator’s preferred UAS flight-planning software, while the magnetometer logs total-field data independently. That flexibility lets buyers deploy it on the fleet already in service rather than committing to a single aircraft.
What makes the dual MFAM cesium sensor design different from single-sensor magnetometers?
The MagArrow II uses two MFAM cesium-vapor sensors combined so that when one approaches its dead zone, the other stays optimally oriented to the Earth’s field. That geometry removes drop-outs during aggressive turns or steep terrain following, which single-sensor scalar magnetometers cannot avoid. The pairing delivers a heading error of only around ±5 nT across full 360-degree equatorial and polar spins, giving clean total-field data regardless of aircraft attitude. For UXO clearance, mineral exploration, and archaeological surveys where a missed reading can force a reflight, that reliability is the practical reason many operators choose the MagArrow II over lighter fluxgate alternatives.
How do I get a quote for the Geometrics MagArrow II from a supplier in Abu Dhabi?
Buyers looking for a Geometrics MagArrow II supplier in Abu Dhabi can submit a quote request through GulfNet Emirates DRS, which serves the entire UAE including Abu Dhabi from its Dubai head office. The Request a Quote form on the product listing captures the essentials: intended drone platform, survey scope, and any accessory needs. GulfNet Emirates DRS then returns an AED quotation with lead time, export-licence guidance, and a proposed configuration. As a trusted seller of Geometrics MagArrow II in the UAE, the team also supports post-purchase steps including compensation-flight setup and Survey Manager training, which matters for government tenders in Abu Dhabi that require documented handover.
What survey applications is the MagArrow II designed for?
The instrument targets work where ground-based or crewed-aircraft surveys are slow, unsafe, or too expensive. Environmental teams use it to locate abandoned wells, buried pipelines, and legacy storage tanks. UXO specialists deploy it for detection and delineation of buried ordnance. Archaeologists rely on it for non-invasive mapping of large sites. Geology and mineral exploration groups use the total-field data to map regional magnetic variation. It also opens up terrain that is otherwise off-limits, including wetlands, dense vegetation, and protected land where wheeled or foot surveys cannot go. For UAE and GCC operators, oil-and-gas legacy infrastructure and desert archaeology are two of the most common project types.
How fast can I fly a survey with the MagArrow II and what data quality should I expect?
The MagArrow II samples at 1000 Hz synchronised to GPS 1PPS, which supports survey speeds of up to 10 m/s while still recording a reading roughly every centimetre along track. The high sample rate also makes it straightforward to filter out UAV motor noise during post-processing. Sensitivity sits at under 0.005 nT/√Hz rms typical, with gradient tolerance of 10,000 nT/m and an operating range of 20,000 to 100,000 nT. Two hot-swappable non-magnetic LiPo batteries deliver around two hours of runtime, which comfortably outlasts the endurance of most host drones and lets crews complete several flight sorties without powering the sensor down.
Can I book a Geometrics MagArrow II demo in Dubai before purchasing?
GulfNet Emirates DRS accommodates demonstration and evaluation requests for enterprise buyers in the UAE and wider GCC. To arrange a session, submit a quote enquiry noting that a demo is required, along with the intended host drone and the survey use case. The Dubai team then coordinates a walkthrough of the MagArrow II hardware, mounting options, Wi-Fi data download, and Survey Manager workflow. Demonstrations are useful for procurement teams evaluating the MagArrow II against fluxgate alternatives, and for geophysics consultants who want to see the compensation flight procedure before committing. Because the instrument is export-controlled, demo scheduling still depends on licensed units being physically available in country.
How is data downloaded and processed after a flight?
After each sortie, the MagArrow II broadcasts a 2.4 GHz Wi-Fi access point that any browser-capable device can connect to. Downloads run at roughly one minute per ten minutes of recorded data, which keeps turnaround short between flight batteries. Raw files are then decimated and converted using Geometrics Survey Manager, and the resulting total-field data is typically imported into geophysical processing packages such as Geosoft Oasis montaj for gridding, filtering, and interpretation. Because the sensor stores everything internally on a 32 GB U3 micro-SD card with an on-board logger, there is no risk of dropped telemetry to the drone, and the workflow does not depend on any UAV-side integration.
What is the best place to buy the Geometrics MagArrow II in the UAE?
For UAE buyers, the practical answer is a locally established, authorised channel rather than a direct overseas order, because the cesium-vapor magnetometer falls under US ECCN 6A006 and cannot be imported without an approved export licence. GulfNet Emirates DRS is set up specifically to handle that process from Dubai, alongside AED invoicing, warranty registration, and Survey Manager onboarding. Buyers who want to buy the Geometrics MagArrow II online in UAE conditions can initiate the order through the product listing, then complete formalities with the Dubai team. This route protects the manufacturer’s one-year warranty, ensures customs paperwork is correct, and keeps regional technical support a single call away.
