GSSI’s new accessory for the StructureScan Mini XT is the Palm XT antenna. It is a miniaturized, hand-held ground-penetrating radar antenna that is designed to enhance the capabilities of the inspection system by providing access in tightly spaced areas and enabling overhead scanning. It features full keypad control via the top that allows for remote control of the user interface and has three data collection modes: standard, cross polarization and side car. The Mini XT can help identify structural elements, including pan deck and concrete cover, and can also provide real-time determination of concrete slab thickness. 800-524-3011; www.geophysical.com.
