Just got a used EXP II from one of our club members who upgraded to a SE Pro. I thought i would give it a try. I was extremely frustrated by the machine and gave up on it and went back to my MXT. After a couple of hours at a very trashy site with lots of digging, I thought I would try the advanced learn mode and scanned a silver Merc and silver quarter. I walked back and forth without a whisper which is almost unheard of with the chatty MXT. After 20 minutes I had a signal and dug up a 1944 quarter which is my first in about a year. Needless to say i am going to love the EXP II although I will keep my MXT. They make great companion detectors depending upon your location, type of hunt and conditions.
