I purchased the MX Sport because I had a old MXT that needed to be replaced. The first Sport was sent back because it didn't work well and with the second I purchased a small 6 in coil to use with it. I keep hoping that I will figure out how to use and trust this detector but am thinking it is just a waste of time. I hunt the beaches near St Petersburg FL and my go to machine is a Minelab Excalibur 1000 as most of my hunting is in the water. Today I took 5 gold rings(3 14k white gold mens wedding bands of various sizes, 1 14k yellow gold mans ring and 1 womans 14k yellow gold ring with yellow stone) that I found with the Excal 1000. and placed them in my back yard and swung the MX Sport over them. not one ring was IDed as gold, numbers from 08 foil to 38 pultab. The only good thing is that it found all the rings. So what I have is a metal detector that I must dig every signal because I can't trust what the screen tells me, what a waste.
