Is the cz 3D water and sand proof like the old cz 6a's were? The wife is thinking of getting a unit and I think Fisher will be the brand she will get. I have a White's DFX and she thinks it would be best to get a another unit that can be used in the rain when people tend to leave the beach.I don't like the rain coat for my DFX, I think she's right! The other unit we are kicking around is a 1280X... The cz 20 is just a little to much money right now. Was thinking used but really want the lifetime warranty!I'm new to the DFX but learning it is going well I have no issues, Finds are going well. I find it as easy to use as I want it to be.I'm the kind of guy who likes a more technical machine. The wife needs a easy to run easy to learn unit as she has never used one before. What do you guy's gals think is best? Thanks for your Help.George
