White's hit a home run with the Goldmaster 2. It was the first quantum leap in their Goldmaster line. From there it got a little better with each newer model, but I feel the giant leap was from the old blue box Goldmasters to the Goldmaster 2. The Goldmaster GMT was also a big leap, as I bought one when they first came out, and was very impressed. Amazingly, My Goldmaster V-Sat was the kindest to me as far as nuggets, probably because I had it the longest. The only one I haven't owned is the Goldmaster 3, but have heard nothing but good about it.
All of the black box Goldmasters are so sensitive they easily detect the salt in a person's hand. Add the reliability of these great machines and you can't miss when buying one, even if it's the Goldmaster 2. The MXT Tracker isn't quite as sensitive as the GMT, but close - close enough. The MXT is so versatile and effective that I don't think I'll ever sell mine off unless White's replaces it with a better version. The find that opened my eyes to the effectiveness of my MXT was made in the Motherlode a couple miles south of Angel's Camp California on an old stagecoach route. I dug up a stunning item that was confusing at first.
It was two rifle shell casings pushed together tight. When they (eventually) came apart at home, inside was a 1909 CA hunting license neatly folded, rolled up and fairly well preserved. It was still very readable, and the color was still fair. The amazing part was this time capsule was detected at 13" using the little Eclipse Shooter DD coil on my MXT in the relic mode. So far, the MXT is my all-time favorite detector. I feel that this model is still the best value today in the field of metal detectors for the price - especially used at $400 - $500. It's money in the bank.
