TTF Question

[helgriffan]

Lately Ive been working on getting used to TTF in a pretty trashy area that has produced good coins. But almost every time before I dig a coin I end up turning it back to MultiTone. I cant seem to tell the difference between a coin and junk in the TTF mode. They both seem to sound the same to me. Someone once said in TTF the coins kind of "scream" at you! But for the most part everything seems to "scream" at me in TTF. It is usually obvious the sound a coin makes in the MultiTone (Maybe because Im used to it?) But I have a hard time distinguishing between trash and treasure in the TTF mode. Any Suggestions?
Thanks Jordan

all signals in TTF sound the same, not sure who told you that coins scream out. But in TTF you get one of two things. a low tone "grunt" for ferrous items and a Higher tone for ALL Non ferrous items.

I think you might be referring to junk as aluminum and such. The only junk dug in TTF is iron and other non ferrous metals. This is why TTF is not to be used at every site. TTF is difficult to use in a trashy park that is littered with can slaw, and the like. If you are not having trouble with multi tone then that is what you should have your settings at. Reserve TTF for non trashy areas and areas littered with iron like a cellar hole. jmho Joe

TTF is simply a "ferrous" or "non-ferrous" indication. On the "Non-ferrous" side, whether it is foil, gold or silver, it will sound identical. You need to look at your TID if you're not prepared to dig everything.

TTF Is sort of like using Multi-conduct with iron disc'ed out and digging every tone regardless of pitch of tone.

Where TTF is very useful over the Multi-conduct is when you are in lots of iron. When in Multi-conduct with iron disc'ed out, if a coin is near iron it will null the coin out due to that iron. Now with TTF in the same situation, you run an open screen, the pattern doesn't disc the iron (you get low tone), you can then also get a high tone out of the coin because it's not disc'ed out by the iron null like in multi, TTF accepts all targets (sort of)

I prefer multi conduct most of the time, you get so much more information about the target. But when you hit that odd iron patch (old stable) TTF is a great setup with a small coil to squeeze out an extra coin or two.

TTF and Multi-conduct are two excellent tools in the etracs settings, you just have to work out which one works best for you and when is the best situation to use it.

I have noticed also that I will get a steady high tone in TTF but the #'s say it is garbage.My machine sometimes seems to be real slow at giving me the real #'s of what the target is if it can due to all the trash. I have swept over a target sometimes 10 times before it would all of a sudden change to a good digging # that turns out good.

Just on the TID number refesh, it will only refresh the TID when the threashold hum returns.

So in other words while in TTF You just dig every solid signal? Is that the best way to do it? I want to Add it to my arsenal so I really want to learn how to use it.
Thanks everyone for the info

helgriffan, When your in two tone ferrous you will only get two sounds, a low grunt tone or a very high sounding tone. When you get a high tone of any kind, even just a little blip of a high tone stop and investigate. Circle your coil around the high tone and see if you can get it to come in better, or separate it from the low grunt sounds then look at your numbers. If your numbers come in good like a coin for example then it's worth digging. Be prepared to here allot of low grunts if your in a area with allot of iron. And like I said you might only get a very little high blip mixed in with the low grunt sounds. That is usually enough to make you stop and investigate the high signal.

TTF is a great way to weedle out those keepers from in amongst the iron dont forget you are probably in auto sensitivity so if you get an iffy deep signal and cant decide whether to dig swittch by using left and right hand cusors lefthand side to MANUAL and watch your signal grow use it as you would a magnifiying glass and when located switch back to auto
