Today's 2 hour T-2 test

[George (MN)]

I went to the nearby school/park I've detectected a few hundred times to see if I missed anything. Got 91 cents, all within 1" of the surface except 1 clad dime @ 4". The sensitivity was turned up to about 65-70 then , I think. It would not seem to pinpoint in the dirt pile til I reduced the sens to 60.

What I'm really wondering about is this: in maybe 95% of the area, I could not turn the sensitivity above 60 without the detector falsing pretty much. It didn't matter if I was close to the powerlines or not. F1-F7 very little if any difference. The detector would get #s showing even when I held it still about 1 foot above ground, if sens was turned up above 60. What's going on, I wonder.

I used the Fast Grab ground balance many times & ground varied from low 60s to low 70s. The Fe reading was mostly .03 I wish I knew how to prove whether or not something is wrong with it? Ideas?

How many have similar ground & how high can you run the sens without lots of false beeps & numbers appearing without real targets? Thanks in advance for any comments/ideas. HH, George (MN)

Hi George

With the id and numbers rolling through the screen it sounds like RF interference. Did you have a cell phone with you and turned on? Radio or cell towers nearby?

I'd try a different site. I have ran into times that my T2 acted similar. Sometimes, it's been fine on one end of the park and not on the other. There is one park that as I get closer to the backside of the park the T2 gets unstable. There is a supermarket about 400 yards away through the woods. I think it might have something to do with the automatic doors or something similar. If you've ever used a radar detector you are familiar with how far away they can pick up the automatic doors. That's using a very small detecting area on the radar detector.

I guess all I can say is try a few more areas. You didn't mention how many you'd tried. I've tried my T2 in 3 different places now. I could always run at least 60 and in a couple places I did 80 with good stability. It just depends on the area.

Disc level plays a part in this. It's also discussed in the manual, that with low disc and high sens, you are also picking up internal noise.

Read the old posts here, I know I've brought up the interference issue numerous times.

I often get interference too. Power lines definitely affect it. Sometimes I have to turn sensitivity down to about 30% and changing frequencies has no effect.

Be sure that any electronic devices you have with you like a pinpointer or cell phone are turned off (some phones transmit all the time).

Basically, I think the T2 is best used on more remote sites, away from populated areas which produce lots of RF interference.

neither effect the T2 much...And even my Garrett 2500 GTI has trouble with falsing when turned up above 70%. I think it could almost normal...But I'm sure it depends on the ground.
