I use the White's Bullseye II. I'm sold on having a pinpointer, just not on the Whites. You have to virtually touch the item to set it off. However, it still saves me a lot of time. It's also fun because I make pinpointing my 7 yr old son's job. I detect and dig the hole, but he always finds the "treasure". Works out well.
I'd highly recommend a pinpointer, just research the models. I don't think you'll see a lot of love for the Bullseye here.
