The Chaser does not have notch or adjustable tone breaks. Those are features I never used when available on detectors I've owned in the past, but some people may want those features. The ground balance appears to be fixed unless you use manual balancing. The manual refers to automatic ground balancing, so that is confusing. I like to keep things simple, so don't miss notch, etc., and the lack of automatic ground balance, which appears to be the case, is not a problem. There is no factory protective cover for the display so I'm improvising with a zip lock bag. I've only put a little over 3 hours on the machine but I think it will exceed the performance of my past detectors and that is the test of whether an equipment upgrade was worthwhile.
