I have a question that I am hoping O am able to get some help with. I got a T2 Limited edition for Christmas. I have been out approx 20 times with my new machine. I previously swung an ATPRO for 10 years and I know that machine very well. Here is where I am having issues. As I get comfortable with my T2 LE I am trying to learn the machine by sound and not by the screen as I feel this is the best way to learn a machine. I first started running it on 2+. I then went to bP as I am trying to get the most depth as possible. I am in discrimination mode not all metal mode. It seems like the Audio is always the same and I can not get a clear difference in the target sounds. I have been using 4 as the newest setting in Discrimination with the sensitivity at 60 the discrimination at 10. I can hear the different sounds now but it still does not seem the a smooth transition and it is frustrating. I am looking for suggestions from any one that is comfortable using the T2 Limited edition. Thank you very much and happy hunting!! Coach

The F75SE and T2SE are basically twin siblings. Run your Sens up to 80 and Disc at 10 is ok. I use 3H tone for basic park or open area hunting. The tones stay pretty much consistent, the thing to listen for is a clipping like sound if its a trash target (not always junk but generally so). You want a good clear tone for coins/jewelry, buttons/tokens, etc.
Otherwise, I believe the T2 can run 99 Sens, Disc 6, Notch 1, and Tone 1. If you can do that you will have to watch the screen but again listen for the clear tone on target, it really works quite well (especially if not an iron trashy type area). Hope this helps.

Ronstar, thank you very much for the useful tips and suggestions. I will look forward to trying these settings on Sunday! Two quick questions, What is Notch 1 and Tone 1?

Assuming the T2 is similar to the F75…… Notch allows you to discriminate out certain ranges but you can Notch in some with in that range. Say you dont want iron, foil, nickel, tabs, and zinc but then want nickels. You can allow nickels back in and still hold the others out (often used to cherrypick). Notch 1 is lowest setting. Tone 1 is simply all detector responses are one tone sound.
Again I have no experience with the T2 but my understanding is very similar to the F75 and made by First Texas which makes the Teknetics/Fisher line.

There is no notch on the T2. In our 80+ GB and multiple bar FeO2 soil, 99 sensitivity is useless as is very low disc. Disc at 10 on a F75 knocks out almost all iron. Iron on a T2 discs out at 40.
Here is a chart:

Model - Teknetics T2/Software version 6.5 (from 6.0 onwards version numbers make no difference in depth according to First Texas Products)
Coin Used - U.S. Quarter - Cupronickel
Coil - 5" DD
Sensitivity - 60
Tone Selection - 4

Discrimination Levels

0 - 9" depth reading (extremely noisy due to EMI & machines internal circuitry noise)
10 - 7" depth reading (approx 50% less noise than 0 disc setting)
21 - 6 1/2" depth reading (quiet)
30 - 6" depth reading (quiet)
40 - 6" depth reading (quiet)
49 - 5 1/2" depth reading (quiet)
50 - 9" depth reading (this is where another huge increase in Gain occurs, besides the zero setting. Same noise level as 0 disc setting)
60 - 9" depth reading (approx 50% less noise than 50 disc setting)
70 - 8 1/2" depth reading (quiet)
80 - 8" depth reading (quiet)

Observation - the Gain does not seem to follow a straight linear output as disc is increased. Notice that from 0-49 disc there is a 3 1/2" range in detection depth. From 50-80 disc there is a 1" range.

0r

If you remove the disc 0-9 results from above, there is a 1 1/2" depth range between disc 10-49 and a 1" depth range between disc 50-80.

The large gain increase at 50 and the 10-49 disc range has serious implications on how a user sets the discrimination. Below are object disc ranges on T2:

Notice the depth is the same at 50 (into foil range) as it is at 0 and disc at 10 reduces depth 2". Reminder: this is the small 5 inch coil. If I had it to do over, when I first got my T2, I should have set disc between 50 and 60 and learned what the good targets sounded like before using less disc. There is a difference in the sound after using it a while. If you get a short beep and turn 90 degrees and get a slightly longer one, it is not a round object. Good luck. I think you have a very competent detector. Switching from one good one to another takes a while to comprehend what the other is saying, especially after using the first good one for as long as you have.

Picketwire,
Thanks for the chart, I was repeating what I had heard. What little I’ve seen just in videos I thought the F75 was nearly the same in readouts.

Picketwire this is great information and extremely helpful! Thank you very much for taking your time to clear up so much of my confusion. It will really help me moving forward!!!

You are most welcome my friend.

The VDI is a separate platform from the tones. They don't run in tandem. Being separate, they compliment each other. I wouldn't limit the machine by only going by tones. You won't give too much credence to one or the other by using both. Best of luck.
