I am thinking real hard about purchasing an Xterra 705. I would like to know how much of a lag there is in the target signal when you pass over a target. Is this unit comparable to a Garrett 1500, Minelab Explorer 2, Fisher CZ, Tesoro Deleon etc... I'm just trying to get a feel for the unit before buying ( I'm sure it isn't like the new F-series they're almost too fast). I really want one of these detectors but I just need a little info. I really like the fact that it can do almost everything as long as you buy the right coil. Also depth wise which unit is it most comparable to ( I've never seen one first hand so I don't have a clue). Is it average, above average, below average for in ground targets. Also how do the tones sound (like the other Minelabs flutey, like the CZ's 3 and 4 tones, Whites tone ID machines etc...
