Short stroll in the test garden

[Jackalope]

First, let me say that I'm not going to get into one of those rants about the E-trac, although I feel like it. Like I said previously, conditions are such that I can run manual #30 without any falsing.

Thanks to my Border Collie, some of the targets in the garden either got dug up or lost. Specifically lost, a clad dime at 8" and a clad quarter at 12". Knowing approximately where they were helped today but that didn't help looking for them before I got the E-trac. Anyway, they both hit hard and I.D was correct. Remember looking at the depth gauge on the quarter and it was almost at the bottom of the scale.

Weather is going to be bad for a while, so I'll be air testing the sounds. Have a good size bag of non-ferrous junk to test and I made a little testing rod out of a 3 ft. long X 9/16 dia. fibreglass pole and a busted 6" plastic putty knife. Putty knife mounted perpendicular to the rod. Works great...got it marked off in inches. Just put the item to be tested on the putty knife with scotch tape, lay the rod in the convenient groove at the top of the coil, then sit in front of the screen and roll the rod back and forth between your fingers.

I can run mine at 30 in Houston about half the time. Otherwise I run M27 or A or A+3. When bench testing I usually disconnect the lower rod and face the coil backwards so that the coil is facing the same direction as the display...wave the target with your hand while looking at the display...both close at hand. You need some separation between the control box and the coil and, of course, have to make sure there isn't any metal around.

How were the Fe numbers on that 12" quarter? The book says they can drop as low as 27, but so far I haven't seen mine do that. Haven't found a quarter at 12 inches either, so I'm curious.

As soon as the snow clears off the area, I'll recheck the FE #.

Snow has cleared out somewhat and I went looking for that 12" deep clad quarter. Running Ferrous 2 tone, sens Manual 30, Deep ON, trash LOW, Fast OFF and QuickMask wide open. Solid high tone on the quarter sweeping from all directions. FE numbers were all over the place but CO numbers on most sweeps were 46 or 47. Depth gauge showed 1/8" from the bottom in Discriminate and right on the bottom in Normal pinpoint. In the field, this would be a definite dig for me. HH

Thanks for the info!
