Me and my wife have been using MXT pro detectors for years but recently upgraded to XP Deus two's and love them but I have a question. I noticed instantly that our XP's ID numbers are much higher on targets than the mxt's are on same targets. I did some comparisons and for instance on a three ring bullet the mxt reads around 52 and the xp reads 82 on same bullet. On a eagle button the mxt reads around 30 and the xp is 60, same thing on every target that I compared signals on, about a 30 point differance. Both of our XP's do the same. Why is this big differance???
