Everyone has different opinions , and they are ALL OK for what each individual's needs are ........My opinion my differ from others , but I see the E Trac as I have said in the past , as an EVOLVEMENT of the Soveriegn ....... The Sovereign is a great machine, and does VERY well for itself when you learn the various tricks to using it .....There is planty of tricks that need to be learned and other factors that need to be taken into account when running a Sovereign .... There is MORE to learn on the E Trac ....There are many more settings , and many more features that you will be dealing with on the E Trac .....It will take you MORE TIME to learn the E Trac , but once you do , you will be rewarded with a machine that will give up the goods in spades ...... There is NOTHING that the Sovereign can do that the E Trac can't do .....but there are MANY things that the E Trac can do that the Sovereign CAN'T do ..... I originally thought that I would have more "Hands On " with the Soveriegn , and that I could adjust things on the fly as the controls were right there in front of me ......This was completely TRUE !!!.....What I did NOT expect , was the fact that once I learned the E Trac , that I DIDN'T have to do any adjusting !!!.....It was more like a SET IT and FORGET IT machine .... The time I spent fiddling with the knobs on the Sovereign , to get a target to sound good , or to check the target , and the "wiggle " I had to do what I call the "Sovereign Rituals " , I acutally spent MORE time dealing with the Soveriegn than I did with the E Trac when finding and ID'ing targets ......In the beginning the E Trac is intimidating , but with the help of others, and with patience , experience, and LEARNING THE MACHINE which you have to do with ANY machine , you will truely be rewared with a SET IT and FORGET iT machine ....If you let the E Trac overwhelm you , it can do that very easily .....If you learn the functions and what they do, and what combinations to use for your conditions, it's a great , and easy machine to run ...... There are targets , and locations of hunting that are easy with either machine , and some claim better depth with each machine and better ID'ing of targets ......i have had both machines , and I can tell you from EXPERIENCE , that the E Trac when learned , is a far superiour machine .....Yes , it's twice the price , but if you are serous about detecting , and your time is as valuable to you as it is with me , the E Trac is a bargain ....Jim
