Radiodetection LMX150SG GPR System | Geode GNSS

Add external GNSS positions to your radar survey

The LMX150SG pairs the LMX150 FINDAR 500 MHz radar system with a Geode GNSS receiver, mount and dedicated cable. This standard SG package adds external positioning without including the RTK upgrade.

Ground penetrating radar records reflections caused by changes in subsurface materials. It can help investigate metallic and non-metallic utilities where ground and target conditions provide a usable response. It does not identify every service or remove the need for skilled interpretation.

Your LMX150SG package

The supplied hardware includes the model-specific display, radar sensor and cart, connection cable, battery with its power-source case, GPR charger and spare parts kit. The Geode receiver, GNSS mount, mounting adapter, dedicated cable and Geode USB charging equipment are included in this SG package. The power-source case houses the battery; a hard display case or full-system transport case is a separate accessory.

From line scans to grid interpretation

Line Scan supports investigation along a route; Grid Scan collects an area systematically. SplitView, MapView and depth-slice views help you compare responses and organise interpretations while still on site. These are tools for reviewing survey evidence, rather than a guarantee that a reflection represents a particular utility.

Positioning: what is included and what it requires

This is the standard Geode SG package. The RTK upgrade is not included; the LMX150SG RTK system is the separate RTK-enabled offer. A paid correction subscription is not supplied. For NTRIP corrections, provide a compatible phone and app, data connectivity and a configured correction-provider account. Satellite visibility, geometry and site conditions affect the positioning result.

GNSS positions describe where the survey data was collected. Their accuracy is separate from the radar’s ability to detect a target or estimate its depth. The Geode package uses the documented custom cable and display settings; an ordinary serial cable is not an interchangeable powered connection.

Compare like-for-like LMX packages

The base LMX150 FINDAR supplies the radar hardware with external GNSS separate. For the package with the RTK upgrade, see the SG-RTK system. Compare LMX200SG for the 250 MHz LMX200 radar format.

Desktop software is separately paid

EKKO_Project desktop analysis is a separate paid licence for supported project exports. The desktop licence is separate from this SG hardware package. See CORE and REVEAL for the separate software offers.

Transport and maintain the right equipment

For transport, the model-specific ATA case with display bag is a separate purchase. Replace worn ground-contact parts with the correct sensor skid plate. The model-specific display unit is a replacement component rather than another complete radar system.

For cart upkeep, compare one standard wheel with the large wheel set. The odometer assembly and cable supplies the travel-distance input, while the spare parts kit provides the listed fitting and support parts.

Power and connection spares

The system already includes its standard battery and GPR charger. For additional or replacement equipment, see the LMX power source with case, matching GPR charger, battery cable and display/main cable. These leads have different jobs. The LMX150/200 GNSS mount is a mount-only replacement, without a receiver or correction-service entitlement.

Understand usable depth and survey limits

The manufacturer lists a collection range up to 3 metres in suitable ground conditions. Conductive ground, attenuation, target size and material, coupling and survey method affect what can be seen. The range is not a guaranteed detection depth. Follow the operating manual and the site’s safe-dig procedure, use complementary locating methods where appropriate, and never treat a clear radar scan as proof that excavation is safe.
