Compass built a great machine in its time. I had (still have) an XP-Pro model - the best out-of-the-box notch machines ever - as long as you didn't want to find any coins deeper than 6". Put a 12" coil on it and it was a good relic detector, too. I went hunting a certain Civil War battle field with other guys lots of times in the '80s and early '90s - they'd find more deep minie balls, but I did better on eagle buttons. Probably because the big coil covered more ground than their stock coils on their Fisher F-1265 or 1266 (the standard really good relic hunters and deep coin hunters of the time). At the time (as I recall) all of Garrett's machines were to big to spend a day in the rough relic hunting - good for coins, heck on the arm in the rough. But the XP-Pro would smoke any other detector of that era in trashy areas. I found more buffalo nickels and war nickels in well-hunted areas than any one else. It's auto discrimination was the best thing going (the first really good notch, as far as I know). Plus most other detectors as light as it was, which was about limited to Fisher products, did not have any meter at all - all tone. My grandkids get to use it now in the parks and tot-lots. Works like a charm.
