what electronics for gulf side of florida?

[machzrcr]

 i am rigging up a new boat   to run charters with in Florida.  and was wondering  if anyone had any recommendations,  i remember talking to one captain down there and said that lowrance had problems with something down there with the satellites.  But i don't remember what it was exactly now.  so before i go and rig up this boat i was wondering opinions on anyone else who remembers what the captains down there run!   i will try to get ahold of a few captains there as well,  but if i can get local help that would be awesome!
