Hi, I am new to the forum and thinking about buying a a 70/705. I have downloaded Diggers e-book and in the process of understanding the x-terra range of machines. I have been detecting for around 12 years using a Laser B3 and mainly Sov xs pro. What are the main differences in actual use bet6ween the sov and xt 70/705. Any of your thoughts greatly received. Thanks xray
