Re: now swinging an etrac, what will be my first silver?
More experienced Etrac users can pipe in, but on the really deep targets, say deeper than 7 inches, the FE numbers are bunk a good rule of thumb is FE 27 or less, but then I read some people digging coins that hit 35. Go by audio on the deep ones (which is hard if you are just learning the machine...). One trick is to listen to what the threshold does. If the threshold nulls out before a good target, then it means there is likely iron around, perhaps located with the target or the target itself is rusted iron. Sweep from another direction and see what the threshold does. If it still nulls, it probably is a rusted nail. At hunted out parks I typically dig all the deep high tones (8+ inches), but then I ended up with lots of rusted nails. Another trick I am trying to learn on those is if the high tone is falsing on rusted iron, typically the pinpoint is way off from the target. Does it pinpoint over where you are hearing the tone or off to the side?
snowskate said:I resent the trash but I do recover it. I did find an old pepsi bottle cap which I thought was pretty cool. Not worth keeping IMO though. I'm hoping for a buffalo soon. I was pretty picky with the signals.. I'm still not sure about a lot of them. Some signals sounded good, but I passed them up because the FE numbers were jumping all over the place and were high.. I figured it was most likely trash. I'll dig more iffy signals when digging conditions are better.
