My grandpa is a big detector and i go detecting with him. We like to research ghost towns and new places to detect. He has a nice White and an old tesoro I think. i use the old tesoro, but am ready to get one of my own. I am going to college in the fall and would like to take one with me there to find some places to detect. I have decided on either the Ace 150 or Ace 250 from Garrett because of price and the great reviews. heres my question. Is it worth spending the little extra for the 250 or is the 150 fine. How much of a difference is there in the two. I like the idea of the 250, but if there wasn't too much of a difference id just save a little money and get the 150. Any opinions are appreciated. Thanks alot
