I have owned more detectors of different brands than I can remember, somewhere around 40 or more. At the time they all worked well for what I was hunting. Now I have Whites, Garretts, Notka, Minelab, bounty Hunter, Deus I, Nautius 2b, and 2ba. All do well for certain hunting. I don't need a powerful machine like the Deus II for hunting around playground equipment. Sometimes I use the Nokta Midi, it goes deep enough for the coins, and I can reject most trash. So, Time, place, weather, soil all has an effect on which detector I use. I don't brag on which is better. You also have to remember that at a depth of 8 to 10 inches, the cone of detection is only about 1 to two inches in diameter so if you don't go slow and swing multiple times in the same spot or you will miss targets, and the next time you go to the same spot, you might swing over the target that was missed. That is why bounded sites still have good targets to find.
