only because I haven't found any "cons" with mine. The X-Terra 70 is a deep seeking, highly sensitive, lightweight, well balanced, versatile metal detector that separates targets well and resets very quickly. It offers two digit target notches, 3 Patterns, an all metal mode, Prospecting mode with iron masking, beach mode, auto GB (with manual GB as well), Tracking, programmable audio tones, noise cancel, pinpointing mode and allows the user to adjust the threshold, sensitivity and volume to their preferences. In addition, it offers a wide variety of both concentric and DD coils, available in 3 kHz, 7.5 kHz and 18.75 kHz frequencies. The ability to chose the coil option for the type of hunting you do is unmatched in the industry.
I invite you to take a stroll through this forum and read some of the posts folks have written about their experiences with the X-70. And, if you have any specific questions, don't hesitate to ask. HH Randy
