I'm currently using a Garrett 250 Ace and wish to upgrade. Trying to decide between AT Pro, MXT and MXT Pro. I'm guilty of trying to get by for less money and often regret my choice and end up spending more money in the long run. I enjoy my 250 but want more. The VDI would be important. I've researched the previous posts and didn't really find my answer. My main interests are coin and relic hunting. I doubt I would ever search for gold nuggets. Any help would be appreciated. The Mxt and Mxt Pro are quite a bit more in cost but I don't want to again short change myself. Thank you. Don
