Ive recieved a few messages asking how to set this up. This is what I do..Set the Detector to All Metal.U can select this from the menu of pre-set programs or u can jump into quickmask ,open the screen wide open and load it to the main screen. Once this is done Go into the Menu and set the # of tones at 2.Then in the same menu select Ferrous sounds.You are all set! Now the rest of the settings are personal prefrence.I like to Run my volume gain at 30 .Im gonna dig any high tone anyways so I wanna hear the tiny deep targets .Im not worried about being able to tell how deep they are with the sound so I set it to max.Id be glad to make a video on my set-up if anyone New to the E-trac is having trouble.Anyone wants a vid plz let me know.Good Luck...HH
