It seems like most of us Etrac owners are in full agreement. I had a DFX for 3.5 years.(my first detector) I did well with it. some of the guys that I would go out with, commented that I picked it up very quickly and was keeping pace with them. (they had an average of 20 years exp.) I then bought a Spectra (v3) when they first came out. I did not like it at all, liked the DFX better. I used it for a year and a half. I never really felt confident, and was frustrated by the audio. I bought a minelab excall 2 underwater machine and really liked it out of the gate. So it got me to thinking Minelab. Like you at this point, i was nervous about dropping 1400 beans on another detector. Anyway, I made the purchase, got it, put it together, fired it up, and walked around in my parents side yard. I was more comfortable in 20 min with the Etrac than I was in a year and a half with the V3. So in my opinion-very short learning curve.
NOT to say the whites are not good units! But I found more silver and coppers in my first year with the Etrac than I did in five years combined DFX/V3 Some of this was going back to sites that I had pounded with those machines.
I found my Tree Coin in one of these sites. Anecdotal?........maybe, but for ME there is no question, and no looking back. That day I was using my Etrac multi, conductive, deep on, fast on, trash high, ground diff. I was using the X5 coil. (First day out with that coil)
I think the main reason behind this is........When you are using a Whites, and you hear the null, your machine is effectively off. Not true with the minelab. I think that some of the V3I users will dispute this and for all I know they are right. I am only talking from my own experiences. As it was said before FBS allows good targets to show through iron. I think that is what makes the difference. The other major factor that I found was EMI resistance. the Etrac is Waaay better at dealing with it.
So, if you want MY oppinion, Get one! (unless you live and detect near me, then you should definately stay with the whites)
There is one for sale right now in the classifieds section at agreat price
good luck, Dan
