It takes time to learn the Sovereign and understand those sounds and tones as to what to listen for. I didn't like the Sovereign when I first got it as most have the same problem. From using it and doing some digging it with some time I did OK and the more I used it the more I learn, now to me it is so simple and easy to use. For me the 180 meter is the secret to my success with the Sovereign . I use the meter to tell the targets that read close to a good target.
Example I was detecting where a bleacher were at a old ballfield that was loaded with both type of pull tabs, the good numbers I wanted were my 180 which is copper or silver coins, the new zinc pennies read 176-177 while a nickel read 143-144 and has a different tone as it is smoother sounding than a round pull-tab , the little beaver tail off the round tab reads 140-141 and quicker or smaller sounding. Now in this area I got a lot of trash reading of both type of pull-tab , got a few coins too others missed also. The one reading sounded like a nickel, but read as a beaver tail of the round pullab which most would not dig, but being it sounded so smooth and a little deeper I had to dig, found a older style gold signet ring that was a good 11 inches down. Over time I dug many small pieces of of misc jewelry and many time my wife would have me check out many of her MXT signal as they were iffy and I could tell her what I though it was so it save a lot of digging for her.
The GT now is a bit more sensitive and do get fooled a little on iron, but see if I come from a different angle I can see the difference and sometimes you have to work the signal with the Sovereign wiggle to just go over that one small area and just do the small wiggle over just the target and see if you get the nice tone. The best one I had was I got a signal in a different ball field and those that were detecting with me said it was iron and a false signal, but doing the wiggle sounded so good in one little area I just had to dig it, found out around 5-6 inches down was a big rusty half inch bolt laying on top of a Franklin half and had the rust spot where it laid. Like I say you use the detector and learn it well and understand what those tones all mean and you will be surprise at what it can do.
I havent used my Sovereign for the last few year as I cant do what i did year ago, I do miss using my Sovereign and use my Troy Shadow X5 as it is light weight a little . Maybe this winter I can find a way to mount the control box different so it wont be as heavy, the figure out get off the ground when I do my digging.
Sorry these post get so long and hope it isn't boring .
