Hello Steve! Hello Fred, thanks for the answer.
I regularly read several times forum and information website. Very useful site, thanks to its members! I want to concentrate the information obtained from the site. In one of latest informations Steve said that he sold the MXT, as it has a large weight. I am willing to endure a lot of weight, if MXT is better nuggets 1-10 grams than similar detectors with frequency 19 kHz ( GBPro). I would like to know that MXT has a problem only with great weight and ergonomics. I understand that the MXT is not a universal detector, he does not see that what he sees GMT and GB2. But I have a starting data size nuggets, mineralization and I hope to pick up these requirements detector.
I understand everything! I will study more information.
