ETRAC FREQUENCIES

[ryanchappell]

I'm not sure why some think that the etrac is not sensitive to gold or other machines are hotter for gold. Based upon what?

SMALL GOLD. Based on my friend digging a nail that was 12-44, and finding a 1-2g ish Gold chain like pendant and necklace in the same hole, located with a Pro-pointer. He swiped the necklace on his E-Trac and got NO READING at all at 6.0-0.0 inches from the coil. This happened this week.

Based on experience.

The E-Trac is my first choice when I'm looking for deep old coins in hard hit sites, but, it isn't very good on small shapedpped gold. Normal sized rings and pendents it dexcellentlent. Small odd shaped earrinpendentsetns and chains, it isn't so good. I have tested it myself and even some of my cheap detectors can do better on some gold. IF the E-Trac used any frequency above 15 KHZ it should be much better on gold. Since it doesn't do well I've got to assume it doesn't use many high frequencies.

...and it's sensitivity to deep silver underlines it's preference of low frequencies...some say the main frequency is about 3 kHz, the outher frequencies make the machine run stable

So if 2 or 4 is great for coinshooting then channel 10 or 11 would be best for small gold right ? Time to do some testing.

I found this on the Minelab site it talks about auto vs manual and witch noise cancel channel is better

The E-TRAC has some very useful

I did a lot of testing of gold but I did not try using different channels. Worth a try I guess.

Channel 1 most sensitive for small targets on my explorer should be the same on Etrac
