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 newest radar technologies, e.g., "Real-Time Sampling" and "Dual-Frequency" multi-channel processing. On the other hand, older systems still on the market only offer older technologies, I.e., single-channel, single frequency, and older stacking sampling.

Dual-Frequency is based on having separate antennas operating at different frequencies. There are many different marketing terms for single-antenna multi-frequency systems but the term UWB (ultra wide band) is commonly used to explain frequency domain filter techniques. The correct way to view these terms are to look at what is creating the "Multiple-frequency", I.e., subtract the term "Digital processing" and all you have left is a single antenna set. The performance on an UWB antenna versus a true dual-frequency antenna is like night vs day scenario. They are not the same and can never be the same as you cannot have the benefits of multiple antennas without having multiple antennas. The question that customers should be asking their GPR provider is, How many antennas does the system have?

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 targets in the earth. Like electromagnetic locators, frequencies behave differently but are predictable from one another. E.g., lower frequencies on an EM locator will go further with less bleed-off, while higher frequencies go shorter distances with more bleed-off. GPR operates similarly but at much higher frequencies (MHz vs. kHz/Hz). 

For example, GPR lower frequencies penetrate deeper soil but have severe blindness in shallow soil, and higher frequencies have an excellent resolution in shallow soil but cannot see deeper. Using more than one antenna set can also provide better data in challenging soil types. Therefore, it is easy to see why manufacturers want to offer a multi-frequency GPR to better compete with systems with multiple antenna designs. Otherwise, they let customers know that their product strategies are no longer competitive. 

However, it is disingenuous to pretend that they are achieving the same performance with a single antenna set as systems using dual antenna sets. Furthermore, it is unfair to consumers who may not necessarily know the difference.

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. It's like comparing tens of thousands of samples vs. hundreds. In addition, collecting so much data allows for background noise levels to be eliminated from the data, making targets seen that were impossible to see on older systems.
