Looking at the YouTube videos for the e-trac they have a big advantage with the conductivity and ferrous numbers both present. Plenty of times with the safari a hear a good target and the number in the high thirties bit can still be junk. Are there any tips, tricks or techniques to get more info out of the target? I've had the safari for a couple months now, love it, love the hobby but don't get a lot of time for hunting so the more information before the dig is a premium for me.
