Dakota DFX-7 Ultrasonic Flaw Detector & Thickness Gauge

Why is it advantageous to combine an ultrasonic flaw detector with and ultrasonic A/B scan thickness scope into a single unit?

Thickness gauges are specifically setup to very accurately measure thickness, locate pits, flaws behind surface corrosion. Flaw detectors are designed to detect, size, position, and differentiate between flaw types in various materials and welded joints. While flaw detectors can also measure material thickness with reasonable accuracy, the are not designed with precision thickness as their primary focus. The DFX-7 combines the two types of gauges into one powerfull and full featured instrument.
