The e-Spade Lite Approach

A practical route into conventional GPR

e-Spade Lite is intended for users who need more direct radar information and mapping capability than a simplified avoidance system, without moving immediately to a fully configurable professional GPR platform.

01

Designed around field outcomes

Select either an immediate mark-out workflow for identifying and marking targets or a utility-mapping workflow for recording and reviewing survey information.

02

Visible radar information

The operator can view subsurface radar responses directly on the field display and apply the selected workflow to the survey.

03

Configurable around the terrain

Choose the XPM2 configuration for compact utility work or the larger-wheel UP400 configuration for increased reference depth and more demanding ground conditions.

04

Transportable field system

The folding frame, adjustable handle and removable battery are designed to support regular transport, setup and field use.

Pre-installed Software Options

Choose the workflow around the result

e-Spade Lite can be supplied with an Immediate Mark Out or Utility Mapping workflow depending on how the survey information needs to be used.

IMO Workflow

Immediate Mark Out

A field-focused workflow intended to support rapid identification and marking of subsurface targets during the survey.

  • Review processed target information directly in the field
  • Support immediate target marking
  • Present estimated target depth information
  • Reduce the delay between survey and site action
MAP Workflow

Utility Mapping

A survey workflow for collecting utility-related radar information and retaining data for review, mapping and compatible post-processing.

  • View conventional radar profiles
  • Record survey data for later review
  • Support mapped utility investigation
  • Work with compatible positioning and processing tools

Antenna Configurations

Select the system around depth, resolution and terrain

Reference depth and resolution values are indicative. Actual performance depends on ground conductivity, moisture, target size, orientation, antenna coupling and survey conditions.
XPM2 350 MHz nominal

Compact utility-focused configuration

The XPM2 configuration uses a compact X-polar bistatic dipole antenna and 200 mm wheels for general utility and near-surface field work.

Antenna bandwidth 135 MHz–835 MHz
Reference depth Up to 1.0 m in wet soil or 1.8 m in dry soil
Reference resolution ±50 mm
Wheel configuration 200 mm diameter wheels
Approximate weight 18 kg
UP400 400 MHz nominal

Larger-wheel, increased-depth configuration

The UP400 configuration uses a co-polar bistatic dipole antenna and 400 mm wheels for deeper reference performance and more demanding terrain.

Antenna bandwidth 273 MHz–717 MHz
Reference depth Up to 3 m in wet soil or 5 m in dry soil
Reference resolution ±100 mm
Wheel configuration 400 mm diameter wheels
Approximate weight 21 kg

Designed for Field Use

Practical controls, transport and power

The mechanical and display arrangement is designed around regular transport, outdoor visibility and operator adjustment.

01

Folding system

The frame folds for transport and storage, reducing the space required between surveys.

02

Adjustable handle

A 365 mm variable telescopic adjustment supports different operator heights and configurations.

03

Field display

A high-contrast 210 mm landscape LCD provides sunlight-readable information with 90-degree operator-adjustable tilt.

04

Removable battery

The removable 14.4 V lithium-ion pod is stated as UN38.3 compliant and typically provides two to four hours of continuous use.

Performance Considerations

Survey conditions determine real-world performance

Published depth and resolution figures are reference values. Ground conductivity, moisture, target dimensions, target orientation, antenna coupling, surface conditions and survey technique can materially affect the resulting radar information. Contact UTSI to confirm the appropriate antenna and workflow for the intended application.
