I picked up my E-Trac just a few months ago. (Malaysian manufacture) Previous user of a great Explorer XS I bought back in 2000 and used it for nearly 10 years. So I am very familiar with the general capabilities of the Minelabs.
The Biggest question for me is How Much Work Do I Let The E-Trac Do For Me? I didn't use a lot of the Explorer's discrimination capabilities other than watching for key indicators on a relative wide open screen. I was running a little iron mask way over on the left side of the screen; about 1/5 of the screen.
Currently, I have the E-trac set up similarly. Quick Mask is down on ferrous 26, I believe, and conductive is set on 4 or 5. Everything else is ALL IN so to speak. I have DEEP - ON to smooth out the deepies and FAST - OFF. Have Audio set with Multi-tones, Limits is 30, Variability up on 29 and a relatively low Threshold tone that isn't annoying. I also have selected GROUND - DIFFICULT, and TRASH DENSITY - HIGH.
So far, I have been impressed by the abilities of the detector for Deep and Accurate Target ID's and exceptional ability to find coins in and amongst rusty nails and other (nulling) large items with the good target. Similar to my XS, but it has better deep target clarity and related, seems to go deeper as well.
I did some minor experimenting with a Gold Coin / Coins Only program that has very small windows opened for GOLD COINS and OLDER US Coins. I was attempting to TEST the E-Tracs ability to isolate a good target signal from all of the other discriminated items; cherry pick so to speak. My first try was in a small, very old park that I hunt when I don't have anywhere else convenient to go. There is one smaller area where I have done well for Merc dime era coins that I keep going back to. I hunted for nearly an hour without finding any good deep signals, just a little new change. This wasn't surprising since this area is rather small and I've gone over it a number of times because it has produced a dozen or so Mercury dimes, a couple silver rings, a few Wheaties and so forth. I was about ready to pack up and head home and remembered the program I had set up and thought I should give it a try.
Then, the worst thing happened. I made several swings and suddenly found myself over a good target reading 12/42 - 12/44 and showing up about 1/2 way down the depth meter. The sound was a little broken up, but left no doubt that it was a good signal. I was thinking I had found a wheatie and up popped a very nice Merc dime at 6" deep. Now I am surprised and thinking 'Cherry Pick' away. I hunted for another half hour and turned up a folded pull-tab tongue impersonating a nickel and that was it.
I tried the Cherry Picking pattern again yesterday at a little area at an old school that has Lots and Lots of trash and deeply covered garbage and galvanized steel sprinkler lines. After finding a few keepers using my wide open Quick Mask program, I headed to the worst area and loaded up the cherry picking pattern. I turned up a newer nickel about 3" deep and finally located a dime signal showing 5" or so on the depth meter. Pinpoint was a little rough and I suspected an angled or on edge coin. Sure enough, it was a bent clad dime only 3" standing straight up and down. It was a nice find only because of adjacent nulls and that I've gone over this area umpteen times with a number of detectors the last 25 years. Shortly afterward, I removed the cherry picking pattern and went back to the Quick Mask. A dozen or so feet further away, I picked up another good signal in tight with some nulled iron of some sort. the ferrous was all over the place, but I kept getting a consistent 44-46 conductivity reading and of course had a nice sound to go with. I was hoping silver dime or perhaps quarter and was disappointed to only come up with a 37-S wheatie 7" deep. It was by itself despite my hopes of finding another coin that might explain the high CO reading. At least it was in very nice shape.
So, as of now, I have about 50 hours of time behind the E-Trac. I have found a several coins in the 9-11" range which impresses me. I typically hunt in manual sensitivity and haven't yet had it over 25, usually in the low 20's depending on where the machine is showing it would be in AUTO sens. I have found silver dimes, but no quarters or halves yet. (All Merc's except for a lone 1902 Barber.) I have lots of Wheaties and a lone IH, a few trade tokens (which I love finding) plenty of newer nickels, but no old nickels yet. I try to pay attention to the lower readings because I like old nickels.
I've mostly hunted public areas this spring to get in practice with the E-trac. I usually hunt the yards of old homes. However, I've actually been finding deeper targets at the parks that give me a little hope that I can hunt them and come away with a few old coins which makes it feel a like it isn't a waste of time.
Has anybody has really good success with the cherry picking programs letting the E-Trac do the work of sifting thru the signal, or is most everybody checking each signal themselves?
