Is my T2 defective?

[George (MN)]

In the air test it says in the manual it will get 10" on a small coin, & it says it will get consistent ID in most soils to 8"+. It doesn't say at what sensitivity.

In my air test, a small coin gave consistent tone ID to 6" & was detected to 8" with varying tones, & not detected beyond 8". One time I used sens of 75 & the other time 80, in the living room. I couldn't turn up the sensitivity higher due to electrical interference.

I suppose Dave Johnson or whoever wrote the manual would be the best person to ask, but just wondering if any of you might have a guess? Thanks! George (MN)

What coin are you using? And did you ground balance the machine first?

Can you do a ground balance for an air test? If so, how? Thanks! George (MN)

I think it WILL read differently IN the ground and I'm fairly sure they are talking about depth IN the ground. Metals will affect the soil around them and send a different signal depending on how long it has been buried. I can't compare mine(air test) as it's in for the update-but I will when it gets back! Maybe someone can compare and write in...?? John

Well I went out and ground balanced mine and tried it with a silver dime. I got about the same air reading as as you. But I don't get that in the ground. My perfromance is is way better in actual hunting conditions. I hit a silver dimne at 7" the other day with a sold tone and ID lock on and I had lots of room for more depth. Next time I will lift the coil and see. I was just out actually and found some buttons and a harness buckle. I am getting better at reading the tones and it's really getting easier to understand them. I don't think there is such a thing as a wrong setting. This thing just finds targets no matter what.

I air-tested a dime at 11 inches, going for maximum depth with a clean response. Which of course meant cranking up gain in an interference-free area and careful measuring. This is probably deeper than it will ID at, I was only checking for audio response.

Ths was with my unrevised T2, I haven't repeated those tests on the R6 revision yet.

I don't think GB will matter in air. GB to the air, or move the GB manually and see if it changes air-depth. It should not, unless you are testing ferrite, hot rocks/cold rocks or stony meteorites.

On my air test it seem like it would give a good signal and ID up to around 7 inches, then the ID would change, but still get a signal up to around 12 inches. This was done indoors in the air. I took it outside and laid a dime on the ground and got much better response on it, so I feel it must see the ground in order to get max depth. This is great as most of my coins are on the ground or in the ground, never got on it the air before.
Take it out and use it and I feel you will see what it can actually do as the target will be deep, that is if they are there and the ID will be good too.
One thing I will say it does love rusty bottle caps and washers.I will also say you need a good sensitive pin pointer as some of these target it gets will be very small and hard to see.

Come to think of it I air tested mine in the factory preset positions and did not turn up the sens. Have to try that again.

Sometimes you can't even hear the electrical interference...but it's there...

For air tests set GB to middle, if possible. If set too extreme depth loss may occur with certain targets. Just like any detector.

Have fun!
