I know I did that for part of a couple of months a few years back just 'cruising' the sports fields. The XLT has great Tone ID performance, especially on the higher-conductive targets such as dimes and quarters.
Also, I know several people who do not like to dig pull tabs and 'junk' so they crank the discrimination up to reject nickels and pull tabs, and a few who also use discrimination or visual TID to ignore hearing and/or recovering screw caps and zinc cents.
I am curious what you other coin totals are of that 2110 and the percentages? Are you intentionally going after quarters? Whether you are or not, with the number of quarters you've recovered, and if you were going after ALL coins, then using my "averages" from over the years you should have recovered about 8946 coins.
This year I am running at 16.8% quarters since May 17th, but over the span of 10 years I have numbers for, I only 'averaged' 11.2% quarters. During a number of those years I was hunting especially with the XLT in parks and sports areas, and I used the 11.2% 'average' to estimate what your coin total could be.
I will also comment that my gold jewelry averages didn't suffer too much when I hunted with the XLT, but that was because I didn't always use Tone ID. Quite often I hunted with Tone ID turned 'Off' so that I got a quicker and better response on lower-conductive targets as well.
It would be interested, at least to me and some others, to see what your totals include in the way of pennies, nickels and dimes, and to know if you're deliberately going after quarters.
Keep it up on the halves and dollars. Since those newer dollars real like quarters you ought to be getting a decent number of them as well. I am only at 6. Heading out in 10 minutes to try and get some hunting in before the rains arrive today and tomorrow.
Good luck!
