I recently finished reading Andy Sabisch's book titled "Mastering the Quattro". I started to find things more easily, but I have been hitting a flat spot the past couple of outings. Are there any other books specific to the Quattro I could read to fine tune the machine. Or do you recommend I read something more broad on coin/jewelery hunting? BTW, I am TH'ing in local desert parks, if that helps.
