Well I've got a whole 8 hrs under my belt with this machine and it didn't do to bad , 54 coins , 1 nickel , 1 junk ring , a skull and cross bones pendant and about 15 pull tabs , mainly the beaver tail type and some of the new ones and some can slaw ( i don't think you can get rid of all that slaw but this machine does pretty well with it ), the notch work well but i feel like i might be missing some gold , i think it is going to take me some time to learn this machine but i think it is going to be a keeper
