Antenna / Laser Positions

Flex NX incorporates two individual GPR antennas:

AStandard Orientation antenna (in front)

and a Cross Polarized antenna (in back).

Each antenna has

three centered line

lasers for highly

accurate markouts.

The center of each

antenna is marked

with a colored

crosshair.

NX Accessory Pairing

Flex NX and its accessory antennas (sold separately) connect

wirelessly using Tap-to-Connect Near Field Communication

(NFC) sensors.

Power on Flex NX and then the accessory antenna. Wait for the accessory

antenna’s indicator light to ﬂash blue, and then bring the NFC labels together

to automatically pair. In future sessions, simply power on the accessory

antenna; NFC pairing will not be required.

Select Concrete Type

When starting a new scan you’ll be prompted to select the appropriate

Concrete Type based the state of concrete cure. This menu only appears once

during each session. Note: This setting will greatly impact depth readings.

While collecting or viewing data, use the Depth Settings Menu to further reﬁne

the depth scale accuracy.

Collecting GPR Data

The GPR data will reveal two distinct categories of reﬂections: targets, and

layers. Targets, such as rebar and conduit, are discrete objects below the

surface and are represented by hyperbolas (orange boxes). Layers are

continuous features, like the slab/grade contact (blue box).

Collecting GPR Data

Closely-spaced targets,

like wire mesh, produce

abundant hyperbolas

that overlap on the sides.

Improving Data Visualization

While collecting data you can tap the icon on the depth scale. This will

open a window with three nested menus: Gain, Display, and Depth. For now,

click the Gain icon in the lower left. Here you can use the slider to adjust

the overall contrast of the data, or select one of three general depth levels

(shallow, medium, deep) to selectively adjust contrast.

Adjusting Display Options

Tap the icon at the bottom of the panel to adjust Display settings. Here

you can quickly change your data display from split screen with both

antennas to full screen options for the standard (front) and cross polarized

(rear) antennas. You can also adjust color tables, toggle the O-Scope, or

enable Focus Mode.
