I purchased a MXT a few months ago and have been learning to use it. I have gotten lots of good tips and advise from this forum. My question is this I performed a small test to check the recover speed of the MXT I placed a penny, nickle and quarter in that order about an inch apart, using a small 4x6DD coil I ran the coil over the targets, now in coin and jewelry mode the unit only produced one beep with a slow or fast sweep speed, now in relic mode with a slow sweep speed I got 3 separate beeps so the question is whats the difference between the two modes besides the number of tones. The answer is probably real simple just not seeing it. Thanks Derek
