As much as thoroughly enjoy Tesoros (especially the Silver uMax and earlier Silver Sabres) I can safely say that my cheap, Chinese {Explorer} detector does as well or even better in this grossly high mineralized (some of the worst on the planet!) soil - than my Compadre does, and it MOST CERTAINLY OUTDOES the Aces, ALL the Aces! It and the Compadres, F-2's, and Whites don't make all that BOING! BOING! annoying noise either. And they pinpoint a whole lot better too. Besides that the aces can't handle bad ground well at all.
For my grandkids and my daughters I bought Aces and the Chinese ones too. The Aces sit in the #$%^*% closet now - because the American Hawks Explorers work better. And.. they weigh only 1.5 pounds too. I can add the F-2 to the lot of ones ALMOST EQUAL TO or outdone by the Foreign ones too. Yes, the China ones have no TID meters but they work better, especially better than the Aces and the cheap White's. When I use them in sawdust tot lots the same is usually true but not always. Sometimes a White's Prism or Classic will get another 1/2 to 1" better in sawdust, but not always. The "Explorer" runs at about 5.5 Khz, ideal for silver, clad, and larger gold items.
The air tests are about one inch less than the Aces, Fishers, and White's, but in the ground there is seldom less than 1/2" difference between them all, a small price for something that works smoother and better. And yes, they also cherry-pick better than the others too - with a near match coming from the Tesoros and the F-2 - both of which I used to own. The original Silver and Golden Sabers though will outdo all BUT the old Compasses for cherry-picking.
For a cheapie I'd get the Chinese Explorer ($89.99) if the child is smallish, a Compadre for a bigger kid, and the rest of the aforementioned detectors might want to to wait for the next bus. There are much better detectors for just a few bucks more. I wouldn't waste my hard-earned $$ on a Bounty Hunter.
If you want a more powerful detector then it's all about personal preference, and little more. Teknetics makes some really decent mid-priced low-weight machines; Teknetics Delta 4000 ($279).
Time for hot chocolate. Maybe a donut.
