OK, first off at the price point DO NOT expect Garrett level detection and discrimination and be realistic that this will take fine tuning and practice to get a feel for where it can shine and where it lacks. From my testing with it so far it seems to be right around where my Bounty Hunter performs and that is what I would expect for this detector. I tested several items at several depths and in short it does discriminate fairly well and usually does a fairly good job of approximately identifying what you're hitting at depth of 4" or less, once you go deeper it starts to fumble the IDs pretty hard and at 8"+ it starts fumbling even detecting. I did everything from modern US pocket change, morgan silvers, actual roman era denarii, 10k gold ring, and 14k 10" gold bracelet along with trash like nails, cut up aluminum can, and bottle caps. If there is a lot of trash or the trash is bigger than the item it struggles. But if the item is lone it's pretty accurate. All in all at the price, it performs along my level of expectation. If you have a Garrett budget or bigger go better but if you have a small budget I don't think you will be disappointed with this!
