They are legal here in Maine. Just like any other
call there are days they work great there are other
times they don't. I've used them to call in birds
and I've used regular calls as well---saw absolutely
no difference in the excitement level of bringing the
bird in ---although I do allow that it does require
more practice/skill to do it with regular calls. To
me it's about like the difference between hunting
deer with a recurve bow or a compound bow---
they are both fun but the recurve requires a lot
more practice.

Because Turkey hunting is relatively new here in Maine
here are very few hunters here that are "really"
good at calling---maybe that's why it's legal here.
