Description

The ProtonScout is the next generation of the Geometrics proton magnetometer, with continuous sampling at rates up to 2 Hz, integrated GPS, and Wi-Fi control through updated MagNav acquisition software and a convenient tablet interface. Choose the ProtonScout Rover for walking surveys or the ProtonScout Base for base-station recording, with 0.15 nT rms sensitivity at 1 s and no manual tuning required. Already own a G-856 or G-857? Keep your sensor head and move to ProtonScout electronics with a legacy upgrade kit.

ProtonScout is available in two configurations: the Rover for walking surveys and the Base for tripod-mounted, long-duration recording. Both use integrated GPS, internal data logging, and the MagNav acquisition app.

For existing G-856 and G-857 owners, legacy upgrade kits provide updated ProtonScout electronics while retaining the existing sensor head.

Proton Scout
 

Features and benefits

Built for simple, dependable magnetic surveys

Continuous samplingSample periods from 20 s down to 0.5 s. The Rover records at 1 s or 0.5 s for walking surveys; the Base records at 2 s to 20 s for long-duration monitoring. Discrete mode is available for GPS-denied sites.
No manual tuningProtonScout tunes itself to the local field. Power on, orient the sensor, and start surveying with no tuning step and no retuning as the field changes.
Wireless control from a tabletConnect over Wi-Fi to an Android tablet running the MagNav app. Set up surveys, watch live readings, and view a heat map in the field with no cables to the operator.
Rover or BaseThe Rover ships with backpack, low-magnetic tablet, and high sample rate license for walking surveys. The Base ships with a tripod and an external power cable for 12 V batteries, for long-duration station recording. Conversion kits move either way.
Plan and track coveragePre-define the survey area in MagNav, upload route files, and set a swath radius to ensure full coverage.
Geometrics quality data0.1 nT absolute accuracy, 0.001 nT resolution, and 0.15 nT rms noise at 1 s across a 19 µT to 110 µT dynamic range.
Built-in GPSIntegrated GPS with helical antenna tags every reading with position and time. No external GPS to carry or synchronize.
Stand-alone recordingStart a survey, switch to stand-alone mode, and walk away. ProtonScout keeps recording to its 32 GB micro-SD card with the tablet out of range.
Flexible powerRuns from a 3S, 4S, or 5S LiPo pack with XT60 connector, or from a standard 12 V battery through the external power cable. A 6000 to 7000 mAh 4S pack gives roughly 8 hours of continuous operation.
Status at a glanceA six-LED panel shows Wi-Fi, GPS, recording, battery, SD card, and system status without opening the app.
Field-ready packageDriver, sensor, cables, and accessories ship together in a transport case. Setup takes minutes.
Software includedMagNav acquisition app for Android and Survey Manager for CSV export ship on the included USB drive.

Legacy compatibility

Upgrading from a G-856 or G-857?

Your sensor head is still good. A legacy upgrade kit replaces only the electronics, bringing continuous sampling, built-in GPS, Wi-Fi tablet control, and 32 GB of internal logging to the proton sensor head you already own. Choose the kit that matches how you survey.
