I was wondering which water machine I should get for when I hit the surf in 2011 (and possibly for some storms this winter). I currently use a Whites Surf PI Pro. I like PI unites but would like a little more discrimination as there is a lot of Iron/lobster traps on the beaches I hunt. I have been doing this for 12 years so experience and learning a new machine won't be a problem. Which machine should I get?
