TTF: How To Set It Up and Use it Properly
Posted by: Goes4ever

I spoke with Ray-Mo and since we are having so many members inquire about TTF, how to set it up, how to run it correctly etc, that I am gonna post my article that I wrote for my website here and make it a sticky. I hope this article will help those who have questions about TTF.

Have you ever ran across an old house, section in a park or an area in the field where you just completely lose threshold due to a massive amount of iron around? Your E-trac just completely nulls over all the iron. No matter how much you slow your swing speed down too, you just can't seem to get the threshold back and pull any targets out of this area. Here is an idea to try! Put your e-trac in 2 tone and use ferrous sounds with a mostly open screen. I use the relic screen, as it only has a small section blacked out on the bottom right corner.



The E-trac has different audio options ferrous sounds and conductive sounds. You all know when you use conductive sounds and you click on quickmask iron screams high pitched just like silver, so running an open screen in an area like described above just won't work. There is no way to tell from iron and good targets,....But if you choose ferrous sounds the iron will produce a low grunt and it makes it very easy to distinguish from ferrous and non ferrous items. Using two tone at an old site can be very productive. Normally this type of site will have very little clad, aluminum, pull tabs etc, so every high tone you get will be worth investigating.

In order to use this method of hunting with the e-trac you must be patient, as it will require you to go extremely slow for two reasons:

#1 going slow allows you to hear that coin or desirable relic sitting directly under or beside a nail, you will get a very audible easy to hear higher pitch tone for the good item and a low tone for the iron by it.

#2 if you go to fast with your swing it will cause you to get false signals from the iron. Slowly down will allow your machine to see ALL the targets in the ground, good and bad.

Like I mentioned above you will need to use a mostly open screen. I chose the relic screen for simplicity, you can use a 100% open screen if you want, try different options and see what works for you. There is less filters for the machine therefore the e-trac has a much faster response time allowing you to hear that coin when before the iron beside it masked it out and you simply got a null and walked right by it. In conductive mode sometimes there is just too much trash/iron for the coin to come thru.

Using ferrous sounds with the stock coin program would be worthless because you need to allow the iron to be heard in order to hear the good target along side it. You need as little as discrimination as possible.

Pinpointing in this type of environment is another tough thing to do, and using the machines pinpoint is not a real choice. When you use the e-trac's pinpoint it is in all metal and it will try to pinpoint the strongest signal which might be the close iron. Here is how you overcome that battle. You get a high tone and you do your best to isolate it from the trash by wiggling the coil over the high tone as you slowly walk a circle around the target until you achieve the best signal you can produce. You might only be able to wiggle the coil an inch back and forth over the good item. Then while your wiggling the coil and still hearing the high tone, slowly pull the coil back until the high tone goes away. STOP, the good target will then be exactly at the center front of the coil. Cut your plug and retrieve your item. (I have a video on youtube and also in the etrac classroom showing this method)

Why use two tone and not multi tone? It may be a personal choice but by using only two tones it is SIMPLE......iron is low grunt, and everything ABOVE iron is a higher easy to distinguish tone. If you use multi tone, it will be murder on your brain trying decipher the musical song you will be hearing. When in this type of iron rich site the numbers will be bouncing all over and with multi tone it will be like a machine gun of tones going off, making it extremely difficult for you to really pick out good from bad. Keep it simple, iron low tone, everything else high tone. Go extremely slow and let the machine do it's job.

I even experimented with 4 tones and this still was too much ear candy for my liking. I suggest you stick to two tones for the best performance and chance of pulling goodies out of all the iron. Also by using two tones you are allowing the e-trac processor to work as quickly as possible giving you even more chance to score the goodies.



Don't expect the numbers on the screen to be solid 12-45 for a silver dime or 12-36 for an indian penny, with the close iron it may very well mess with your numbers, pay more attention to the conductive number. Listen for a clear high tone, try to work your coil around it till you get a nice clear tone, without a broken, scratchy sound. The first indian I found using this method gave me a 07-35, it had iron all around it. If I had waited for a 12-36 it would have not happened and I would have kept walking.

Using this method you WILL detect targets other machines have walked right over many times because their machine either nulled over the iron and did not see the good item or their machine

TTf's great--use it often , also to verify deep iffy signals when the diggings tough , but now the $64 question:
How do you deal with old galvanized roofing decomposing under 4" of dirt.?

find a new site :rofl: in all reality if a site has that much roofing in one area, your only choice may be to just move out of the area, sometimes that is the only option. I have had sites before where I knew there would be goodies but the ground conditions or amount of trash in the ground simply made it not worth the headaches. This hobby is supposed to be fun and if you have an area driving you nuts.....move on!

Thanks for the great explanation on TTF setup and use. I am currently hunting an 1835 homesite with original house and outbuildings. Loads of iron and have been working in multi tone with multiple responses. I am going to set my E-Trac up as described and give it a run today. Will post results.

I have a couple of questions about using TTF. First, wouldn't it be more effective to use FAST ON and DEEP OFF while searching in TTF? That way there is less filtering making the Etrac's processor faster to be more effective in target separation? Second question: I find alot of coins in conductive multi tone where the ferrous number is above 17, usually in the low 20's. If I was using TTF in this situation, I would have missed that coin because it would have given a low grunt, right?

regardless if I am in conductive or ferrous tones I use FAST ON and DEEP OFF. I feel it gives more accurate readings.

And as for the the other question, if your using TTF it is because you would be in an area where conductive tones are not working for you because of the high iron and constant nulling. So it is possible you might miss a coin that would come in higher than 17, but to be honest, there is always gonna be some coins that we will never get regardless of what we are running, or what machine we are using....no one gets it all!

Thank you for GREAT explanation of TTF. You obviously spent a lot of time writing the article and it's appreciated.
I look forward to trying your settings the next time out and I'm sure a lot of readers will benefit from your advice. HH

Terry helped me set up TTF on my machine about two years ago and at first I HATED IT that was because I did not really understand it, I was swinging too fast and too impatient to really LISTEN and isolate a signal properly. He invited me up to hunt with him so I got a little more hands on instruction. At this time I had never found an Indian Head he told me "Come up and I bet you will get one" he took me to a field site, my first field hunt and sure enough I found one and to boot my first Barber Dime. Understand it will take some time to learn it but whatever you do please STICK WITH IT! I guarantee you will start making some finds that would be impossible to find any other way. His way of setting it up is simple and works so well that after awhile at some sites which have areas of heavy iron and some clean spots where you could hunt reasonably well in conductive you find yourself sticking with TTF. Another way to use it, if you have a spot where you have hunted hard with Conductive go back even if it did not appear to be heavy iron, hunt it again in TTF and you will surprise yourself with what else you may find. Here are a few examples of some things I found in TTF that I KNOW would not have been found any other way. I tip my hat to Goes4ever for the immense help he has given not only to me and my wife but everyone else that has heeded his advice. These are just a few of the great items I and my wife have found using it.

Look at the Reverse of the 1805 Draped Bust Large Cent, you can see where the square nail was laying on it. This was dug by my wife who was just learning TTF at the time she said it was a choppy signal but she could hear the high tone coming through, she had only been using an E-Trac for about 6 months at this time.

Not that I was a disbeliever before, but I definitely will be using this mode more often. Today I went back over the area where I found my first E-Trac silver yesterday. The site is moderately trashy and yesterday I walked a grid using a slightly modified coin program, a 10X12 SEF coil and ran Manual 25 for sensitivity. I found quite a bit of clad, but I could tell there was other targets mixed in with the trash. So today I went back with the 6X8 SEF and ran TTF with Auto +3. Essentially the same area I hit pretty hard yesterday. I found an additional 6 quarters, 16 dimes, 6 nickels and 23 pennies. All clad and modern nickels and pennies, but I was amazed that I had missed that many coins. In case you think I was slacking yesterday, I had a Kennedy half, 5 quarters, 7 dimes (one silver 1946 Rosie), 3 nickels and 23 pennies. I certainly will be using this mode and coil again when I'm a tough area.

I'm still trying to figure it out. I found the site of an old school. The site looks great and I was told the owner didn't think it had been hunted. The first day the ground was pretty well frozen so I didn't hunt long but managed a 1917 wheatie. The next day I took a friend and we hunted for 2 hrs. without finding anything and my friend was ready to leave and I said lets give it just a little more time. Well shortly after that he found an 01 barber half and an 06 barber quarter 6" from the half and thats all we found. I went back today for an hr. and a half and tried TTF because there was a lot of rusted iron and didn't find a thing.I was disappointed because this site looked really good.

My experience with TTF (about 6 months, I have had my ETrac >4 years) has been great! TTF reinvigorated my hunting.

Your description of how to set it up is spot on and it is so easy to switch back and forth when hunting conditions change (or I want to give my ears a rest). I also totally agree with your comments about the 6x8 SEF coil. That 3" difference really helps you hear in trashy spots.

One thing to note to new TTF users, this type of hunting is much busier than you will be used to. Some of my hunting buddies don't like it because it is so "busy" and you have to FOCUS.

TTF has opened up sites I thought were done and we have found much silver and clad in TTF that conductive hunting couldn't see.

TTF actually made me park my new XP Deus (which I am considering selling now).

I don't use anything other than the ETRac now that I can switch back and forth.

Thanks for putting this information out there!! There will be much less left in the ground now!

TTF is the bomb. only thing that i don't like is all the noise. but it beats hunting and not finding anything cause your detector is nulling out non stop.

I have been experiementing with it and I really love it too. Your nickel finds will definitely increase!!! lol. Used it yesterday on a site. I retrieved an old mik can lid, a wheat, and a 1920's radiator valve from indoor heater system. I went over that area several times. Lots of iron in the ground and TTF made it much easier to find these items. Very cool ... thanks for the tips!!!

I have a house that I have been hunting for the last couple days, it is right across the street from me, it was built in 1914 and the original owner that built it, owned all the property for about 1 mile square around. It used to be an apple orchard. This yard is incredible, it is so littered with iron, it's like a carpet:surrender: Can't even move your coil 1/2 inch without an iron sound around the side of the driveway area:surrender: But I have not given up! First day in TTF I got 9 wheats in one hole, a 1943 Mercury dime at 8 inches deep, a few more wheats and a few really deep older style pulltabs. I am using a Sunray 5 inch coil, I will try to use my 8X6 today. Yesterday I hunted for an hour and a half and got a 1935, 1952 and a 1964 dimes, 11 copper pennies, 1959 to 1964, some kind of token encased in what looks like plywood with a big letter "F" in it, annnnnd a very thin gold ring 10kt. People are right about the numbers, when ya get a higher tone, they are all over the place.....JUST DIG 'EM! I have permission to hunt this yard, it costs me no gas to get there, and TTF rules there.........NGE
