I would Put The X-terra line of Detectors in the same class as some of the other brands mid to high end lines. 
 I do not personally have a considerable amount of time on these machines but I have enough to know they are easy to use, very light and can reach depths that some of the competitions high end machines cant. With the different frequencies and several coils to chose from really makes these machines capable of being used just about anywhere for all kinds of different hunting needs.
 
A very good friend of mine who goes by the name Goes4ever on buckeyetreasurehunter.com and minelabchat.com has had some incredible finds with the first generation X-terra 70 and below I will share a few of those with you.
