Ferrous or Conductive?

[bigfootokie]

I recently purchased an E-Trac and I am in the process of setting up a silver program for deep coins that I plan to use at hard hit sites. I did a search on the forum but I am still wondering if Ferrous or Conductive would be better for silver coins only. I am leaning toward Conductive but would appreciate input from more experienced E-Trac users.
Thanks,
BFO

Most everyone uses Co for normal sites and runs two tone ferrous (TTF) for trashy, heavy iron sites. I am sure someone out there uses multi tone ferrous but I personally never have. I believe that was what you were asking.

Conductive here.

Conductive 99.9 percent of the time, and Ferrous in only the worse iron infested locations. With a small coil.

Probably conductive. Could black out ferrous 1 thru 16 and conductive 1 thru say 40 and hunt in TTF for silver.

For me, it depends on the ferrous and conductive values of the targets I don't want to dig, opposed to the targets I want to dig. For example, if I am hunting in an area with lots of old rusty iron, such as an old farm site, many of the iron target will respond with a conductive value similar to the silver coins I am hunting for. In those places, I chose two tone ferrous because those iron targets will give a low ferrous tone rather than the higher pitch of the silver coins. Plus, there is very little "modern trash" at those sites. Using TTF allows me to maximize my time in the field by allowing me to "hunt by ear". On the other hand, if I am hunting a modern area with a lot of pull tabs and foil, I will chose conductive tones because if I kept it in TTF, those same pieces of foil and pull tabs will give the same high ferrous tone as the silver coins. With a multiple tone conductive audio response, you can hear the difference in the targets conductive values between silver and most trash. Here are links to a couple blog posts I made on Minelab's TreasureTalk site regarding ferrous and conductive tones on the E-TRAC, which explain my preferences in more detail.....

Thanks a lot guys, your replies have answered my questions quite well. I understand now that hunting conditions will be a determining factor as to which audio I will need and may change from site to site depending on types and quantity of ferrous/nonferrous materials I want to avoid digging.

I appreciate the input.from everyone.

If you clean out an area in CO, sometimes if you go back in TTF you will gets some high peeps you might have ignored in CO.

Digger is correct. Seems the areas I hunt that are old have so much iron that if I search in Conductive MT that I am always thinking I am hitting silver. I use FTT almost all the time. When I hear the upper tone I just look at the numbers and decide to dig or not.

The etrac in FTT has hit good coins right next to iron. It is simply amazing.
