Nick have you ever used a Compass machine and if so did you become proficient with it? Have you ever used a Wilson machine? Do you hunt mostly parks or other enviroments?
I think you have misunderstood my point. I like you have found the Etrac to be a great machine as well as the Explorers, Sovereigns and Musketeers. I have made many amazing finds with each of these machines. The Etrac does do well with picking through trash I agree with you there. I like you have found the brunt of my silver coins in an old park setting that has been hammered to the point that other detectorist have wrote it off years ago as hunted out. I have found silver coins with nails welded to them or in the hole with a big rusty bolt and been amazed at how great this machine was and how great of a detectorist I must have been to have found them.

I make several detecting trips a year hunting to different parts of the United States and Canada. I have discovered that in different areas of the world, same targets can sound very differently. I thought I was as good as anyone with the Etrac until I took the machine to other parts of the country. I found that iron ore changes and ground minerals change depending on the part of the country your in. I rarely dig a piece of iron or aluminum in Tennessee but in Ontario Canada, Buffalo NY, Louisville Ky, Tulsa Oklahoma, Jackson Mississippi, Shreveport Louisiana it takes me 2 or 3 days of detecting to get to where I semi-accurately identify iron or aluminum and not dig it. Take a trip to another distant locale and I think you'll understand what I'm talking about.
In rough plowed farm fields apparently you didn't have some one beside you cleaning your clock with an old machine. I have had this happen on multiple occasions. Going directly behind me over the same areas that I had just been over with the Etrac digging coin after coin and button after button that me MR ETRAC MASTER had just left in the ground.
Trust me there are some enviroments that the Etrac is not all that.
Will the Etrac correctly identify deep targets better? Without a doubt
Now let's be realistic, I like you have a high silver coin count but how many of those coins have you dug that were 5" - 6" deep verses how many were 10" - 12" deep?
I bet at least 70% of these coins fell in the 5" to 6" range.
This alone is a true testament to the Etrac's ability unmask targets that other detectors/ist have missed. If you agree to the above statement then you must agree that MASKING not DEPTH is at least 70% of the battle. Not to discount depth but it's truely not everything.
I think your a great detectorist, you would have to be to have found all the silver you have located. My hat's off to you.
Can I go behind you with a Tesoro, Compass, Wilson, Whites and find coins or valuable relics you've missed YOU BETCHA.....
Could you go behind me or Joe with the Etrac and us with the Compass and find coins or valuable relics we've missed? Without a doubt.
Could I go behind you with the Etrac and you with the Etrac and finds deep silver you left in the ground. I would say so
Or if you stepped behind me with us both on Etrac's and you find a deepie I missed. I would bet money on it.
This comes back to you can't get it all. I just like to have more in my tool box than a sledge hammer sometimes a tack hammer does a much better job

If you hunt parks 90% of the time stick to the Etrac don't sway.
If you would come hunt with me at some of my old homestead sites I promise you it wouldn't take long for your to start doubting the mighty Etrac.
I am not brand specific by no means I own and enjoy many brands and have found that a person of average intelligence can become proficient on multiple machines but not without A LOT of time in the field.
Ask yourself with all the different machines out there why is there still a market for the older machines. I happen to know many guys that can afford the latest and greatest that still prefer the older machines. Why can I sell an old outdated obsolete Compass for near the same money as a barely used F75? Dog gone there must be a reason...
