It looks to me like the calusa place that Elwood referenced sells top of the line equipment...but this is coming from me (aka - someone who knows nothing about cast nets). I had no idea they had so many cast nets available...so if you want to catch your own bait on Lake Cumberland or Dale Hollow...which net would work best, a 1 1/2" mesh x 12' high net, a 3/4" x 12' high net, a 5/8" mesh x 10' high net or blank x blank ????????? They had more nets on that site than a person could shake a stick at.

I'm guessing the larger mesh nets are for salt water use and the smaller mesh nets are for inland lakes.
