The F2 has served me well but we had to part. So It's an F5 that's in the mail to me now. Went for the addition of the 5 Inch DD to be included in the package. So more beach work and more searching for pre-decimal silver and pre-decimal gold (I hope). Should even be able to balance out ground in the gold fields if i ever find myself out that way. I'm in Perth WA.
