The PinPointR GPR system from Impulse Radar provides best-in-class performance, ease-of-use interface, and unparalleled value to the entire utility locating industry. The PinPointR GPR cart features a dual-channel radar antenna, i.e., 400MHz (LF) and 800MHz (HF), and features RTS technology (Real-time sampling), providing enhanced bandwidth and superior resolution. Real-time sampling (RTS) gathers more data faster, substantially lowering the system noise floor, effectively increasing signal penetration and resolution. As a result, the PinPointR is the perfect GPR cart for locating deeper utility targets with maximum depth penetration or near-surface utility targets, even in the most challenging soil conditions. In addition, the PinPointR easily outperforms all other systems, especially older single channel GPR's.

Features include: ViewPoint mapping, ease-of-use operation, dual channel radar antenna (400/800MHz), (RTS) Real-time sampling technology, a composite weather antenna cover, light weight folding cart, large off-road wheels, fully wireless Android tablet operation, *Ruggedized Tablet 10.1"/TFT, MIL-STD-81DG and IP68 rated, accurate built-in GPS (also accepts optional external RTK-GNSS), provides automatic utility report generation which verifies site visit & ticket sign-off, long lasting Li-Ion battery (7-hour) and 2-year warranty.

Available options include: EMLID Reach RS2 Multi-band RTK GNSS receiver, External GPS Mounting kit, Samsung Tab Active Pro ruggedized tablet, Spare Li-Ion battery & charger, CrossPoint PC Visualization software, Pelican Tablet case, Light-duty Transport case and Heavy duty military style PolyethyleneTransport case.

The PinPointR antenna includes the industries newest radar technologies, including Real-Time Sampling and Dual-Frequency multi-channel processing. Older GPR designs still on the market today typically offer older technologies, I.e., single antennas, single-channel, single frequency, and older stacking technologies.

Proper multiple-frequency GPR requires the use of separate antennas operating at different frequencies. However, some manufacturers claim their single-antenna GPR systems can replicate multi-frequency GPR performance. These systems often utilize frequency domain filtering techniques and insert marketing terms to insinuate equal performance. However, comparing new multiple-antenna, dual-frequency data with older single-frequency systems is like comparing night and day. Therefore, consumers should ask their GPR providers, "How many antenna sets does the system have?" before committing to an order.

Ground Penetrating Radar is a definition associated with radar signals being able to penetrate the soil and, as a direct result providing the ability to see utility targets in the earth. Like traditional EM locators, signal frequencies behave differently from one another. i.e., lower frequencies go further with less bleed-off, while higher frequencies go shorter distances with more bleed-off. GPR systems operate similarly but at much higher frequencies (MHz). 

Lower GPR frequencies can penetrate deeper soil but also have severe blindness in shallow soil. On the other hand, higher GPR frequencies have an excellent resolution in shallow soils but cannot penetrate deeper soil. Therefore, using more than one antenna set with multiple frequencies often provides the perfect system for detecting shallow and deeper utility targets. In addition, dual frequency systems also benefit users in more challenging soil conditions. Therefore, it is easy to see why manufacturers want to offer a multi-frequency GPR to their customers.

Antenna design is a highly complex subject. But attaining the optimized spacing between the transmitter and receiver blades is critical to achieving optimum performance with the targeted frequency. You will notice a higher frequency system has a much smaller footprint versus a lower frequency system that is much larger. Of course, a person could apply different frequencies to either blade configuration. Still, the results would be severely unsatisfactory unless the person uses the exact frequency at which the antenna is optimized to operate. Achieving high performance is why a dual-frequency GPR system will always have dedicated antennas for each frequency. Unfortunately, some designs on the market today do not meet these standards.

The other aspect of frequency choice is data collection sampling. The data that is displayed on your display is also a result of many samples averaged together. Comparing data with hundreds of samples versus thousands is remarkable. But when compared with tens of thousands, it is profound. That is what Real-time Sampling provides.
