The "beeps and chirps" are probably trash, possibly coins. This is where intimate knowledge of your hunt site comes in. Just cause we want it to be so, doesnt mean old coins are on "virgin" ground. Most things we search for are not too deep most of the time. Yes they can be but not as often as we might think.
No matter what you use, to get to the extremes of depth on those few coins that lurk deep you will have to run wide open and overlap your scans. Running wide open will induce all manner of "chirps and pops" and it falls to you to learn the deep one's from the shallow trashy ones.
At depth, the field of coverage from your detector narrows to a quarter size area. You have to overlap to do any good down there.
Again it goes back to knowing your ground. If there aint nothing there to find it wont do you any good to do all of this. The Cortez offers good performance in most ground conditions. The very BEST on ALL ground? No. To get that, you willl be back to making concessions. Get the Cortez, use it alot and enjoy life. Dont worry about what you may be missing.
If you miss something today, you'll get it next time.
Or maybe not.
Maybe someone else will get it instead.
Or maybe not
Either way, someday you'll die and leave it all behind.
No choice.
Act accordingly.
