Its an older machine but still has advantages that make it worth considering.
All metal (non motion) is a good deep mode with the stock coil. If wanting to go deeper for cache hunting/relics you have the option of tuning it into a two box detector.
In discrimination it has very little iron bias and will be a little noisy over rejected iron though there's no doubt that it is iron. The plus side is that it has a quick recovery speed and doesn't suffer to badly from target masking.
On negatively mineralised clay you retain depth in the non motion mode but discrimination accuracy goes downhill. My old XLT was far better.
Lots of features, some good like the two tone audio options and others that are best turned off, like surface blanking and the audio description.
I've a feeling that the ground tracking (which works well) only operates in all metal and is fixed in discrimination in the same way as with the Tesoro Lobo Supertrac.
Not a machine for wet beach use and I would check with Garrett what the repair situation is before parting with any money.
