Consider, you are extremely limited as to what you are allowed to shoot.... carp only. And for the most part its all short range, inside of 15 feet, 20 feet on a really good day. If you are interested in traveling to Ok or Ar, to hunt that will widen your target range a little and may extend your range of visibility. I havn't dove any lakes in either state.
This information will help the decision. Once I make the jump, I'll make three purchases, a pole spear for floundering in shallow water, a salt water gun, probably a biller, and a fresh water gun, something short.
