I'm finding when using TTF I get a lot more signals reading lower in the 1-31 to 1-38 range has anyone else noticed this and if so could you shed some light on why it does this. I dug a 1910 dime that read 1-38 in TTF and when I switched over to muilty the signal jump 5-38 9-38 5-40

TTF

Check out Goesforever's web site. He has a great explanation of TTF and how it works as well as other great information. As far as the numbers you describe pay very little attention to those ferrous numbers. A good solid conductive number along with a good tone is ideal BUT that usually is not the case. HH

A 1910 Barber dime (1892 - 1916) is a mixed allow of 90% silver and 10% copper. On E-trac those silver coins fall mostly above 36Co and lower than 13Fe, usually the silver comes in at readings like 01-13Fe with 36-48Co. Your silver dime is behaving normally.
By the way, the TID on the E-trac is independent of the tone settings: TTF, TTC, MTF, MTC, 4TF, or 4TC. The tones simply divide the low, med-low, med-high, and high tones, or in the case of multi-tone you get a variable tone pitch. In TTF that silver dime is a high tone. In TTC that silver dime is the same high tone. The TID will still be 01-38.
Interestingly some people will Disc out the 01Co line to avoid falsing from deep iron (wrap-around tones). It is possible to miss silver that occupies that location too.
