Tnfishdaddy:
Please go to DFX forum.ask Larry(IL) if he will be kind enough for filling you in on the attributes of the DFX..He is very qualified.
I am fairly certain he and his wife also use the MXT.he's a good guy and will help you very much in your selection process.
You must remember though the bottom line choice will be yours. Each and every one of us feel the detector we use is best.
Thats not saying we do not know anything, it's just, sometimes, a matter of opinion differs from model ,to model. What works for me, or someone else may not be your idea of the perfect detector. I have used many different makes and models and find just about all of them work very well. I on the other hand do not like some of the models and makes because of how they work, or what options they offer etc etc..but that does not make them a bad machine. It just means I did not care for them. I prefer the XLt.it's in my opinion an almost do it all detector. It has depth, adjustments for just about every hunting need and will work most places well..Even the beach..but saying that the DFX works better at the beach..It has two frequency's and the higher frequency is more in tune for whats lost at the beach IE: Rings.The Xlt will hunt the beach just not as well.........See what I mean about preference, opinion and detecting???? Check them all out.
Get opinions and then decide what will do the most of what you want. No machine will be perfect....
