How It Works
High-Profile Technology Does The Detective Work
 Simply put, the SeekerSPR shows you what is on the other side. Slowly move the unit over the medium you want to investigate, like a wall, concrete floor, road or any other non-conductive surface. The SeekerSPR’s antenna sends safe ultra wide spectrum RF energy pulses through that medium and back to the antenna to create an image of the sub-surface on the operator interface. For you, it is that simple.
The SeekerSPR has the same basic principles as a metal detector. A metal detector sends energy into the earth in up to 17 frequencies. When that energy meets a metallic object, it is translated into a recognizable tone. The SeekerSPR sends out thousands of frequencies that return to the antenna and translate material composition definition in the sub-surface.
Choose Your Depth
Naturally, material compositions closer to the viewing surface produce a higher image resolution. Knowing your depth requirements is important. The depth of your findings will be determined by two factors:
- Soil type
- Antenna strength
Clean, dry sands provide the best conditions for investigation. Dense, wet clays are harder to see through because the frequencies are absorbed by the soil, providing less frequency feedback. The type of soil directly affects which antenna strength you choose to search your required depth. For example, a 500MHz antenna used over dense, wet clay generates approximately 6 ft. (1.5 m) of penetration. That same antenna will generate up to 15 ft. (4.5 m) of penetration over clean, dry sand.
 Recognizing
What You See
Unlike a photograph, the image created by the returning frequencies shows patterns like you see here. Angled or curved lines don’t naturally appear in radar data, which means a soil disturbance or a material composition unlike its surroundings is in the sub-surface. With simple training, you will be able to quickly recognize abnormalities and patterns beyond the other side of your medium.
