Yes Jim the E -Trac is a great detector too and I do have one with 5 different coils to try out myself and for others around here too see which will benefit us the most. I am getting to like my E-Trac the more I use it, but still don't have the confidence in it like the Sovereigns, I am sure by using it I will get more confidence in it and probably be my main detector, but I will still have at least one Sovereign around with a 180 meter and a S-1 probe on it.
On the E-Trac I hunt in Quick Mask set at 22 ferrous, 9 conductivity, auto sensitivity at a +3 (first detector I like the auto sensitivity as this one works) both fast and deep off, difficult ground on and my response pitch hold to help hear those weaker signals. I find on any iffy signals I can change my quick mask to easy to check out any signal. I also run the multi tones and listen to the tones first and how they respond before looking at the meter, then it is conductivity first then the ferrous before i decide to dig. Because of health issues I was only able to use it once this past year and the GT 2 times, so i hope by spring I can make it up this year, I know my wife does as she loves detecting too and my best hunting Buddie.
