Its been a while since I used the MXT but I still have my Sov GT. You really can't compare them side by side as the GT is a multi freq detector with no screen and the MXT has a screen and the screen lies to you. You soon learn the screen is for reference only and reports on what it could be. But newbies think if the screen says its a dime, it better be a dime or they are calling the factory. I tried the MXT on the beach once in the dry sand only near where the van was parked with the Sov GT was resting. A buried clad quarter a foot down the MXT couldn't respond with the same size coil as the Sov GT in the same mode. Then in all metal, the Sov GT went even deeper. MXT can report rusty iron as good targets while the GT does not.
