I think some might have misunderstood my question on GB,I 'm not frusterated with my 250 I'm very happy with it,in the last two weeks I have found 2 rings lots of change and lots of other very interesting things.The reason I was wanting to upgrade is that I have found so much with my 200 dollar investmant I could only imagine what I would find if I upgraded to a 1350,1500 or 2500.Buy the way,I am so happy with my garrett 250 that I am only looking at garrett MT.Thanks Jason
