What to Look for When Buying a GPR System
How to Choose a GPR System
GPR system choices on the market are plentiful. As demand increases and the features of ground penetrating radar vary, it is important that first-time customers know what to look for in a well-made GPR system.
Rugged Design
Look for a GPR system capable of handling tough weather conditions, terrains, and environmental factors. A well-made system ought to be built to military-grade specifications with hardware that can traverse the most challenging landscapes.
System Versatility
If you are using a GPR system for a singular purpose, such as utility locating, then there is no need to buy a system that applies to geophysical research. However, if you want a system that can serve a variety of needs, you should look into a multi-frequency system or modular system. In terms of specifications, the antenna frequency (or range of frequencies for multi-channel systems) will be the most important factor when looking for GPR systems geared towards specific applications.
Warranty
Always ask what you get in terms of warranty. Some manufacturers offer more confident terms.
Training and Support
GPR can be taught to multiple crew members in the span of day. Ask the manufacturer what training they provide, its cost, and availability. Customer service and support are critical during the startup phase. Look for support from a manufacturer familiar with your application(s) and how to use that system effectively in this context.
GPR Software
There are numerous GPR software options available, from simple reporting to data post-processing, GPS integration, and 3D. Some of these options can prove pricey, and in some circumstances, may even cost more than the GPR system itself. Look for a system with equipment capability that can expand as future needs arise. Can you later add options at a reasonable cost? Look at the software features and determine which package(s) best match your needs.
Field Data in Application
You should consider the quality of data that a system can provide pertaining to your application to see if the radar systems offered by a manufacturer can handle your locating requirements. Some manufacturers offer systems that can calibrate to environmental conditions, while others do not. Learn how well their product can perform across a variety of conditions, and keep in mind that your best option will always be the most versatile product because any conditions can vary with weather, seasons changing, and a variety of other variables.
Control Unit Specifications
When purchasing a system, the control unit specifications are critical. Is the screen glare-resistant? Can it endure tough weather conditions? How much memory and hard drive space does it have? The processor, USB connectivity, and other export options? Another important aspect to consider is its intuitiveness. Does it use a complex, proprietary operating system or something more user-friendly like Windows?
