I started predator hunting ohh...7-8 years ago or so, started out with a cass creek caller with a 50" cord to a little speaker, never seen a thing, then switched to a MP3 player with a cass creek big horn speaker, called in my 1st coyote with that.
then got a foxpro firestorm (refurbed direct from foxpro) and have been very successful ever since.
This year upgraded to the fusion, no issues with the firestorm, just liked the new features of the fusion, and am on track to break my calling record from last season all ready.
Now I must admit that a lot of my success has from learning how to hunt, but believe that alot is attributed to the foxpro as well, the remote, sound quality are second to none in my opinion.
I have hunted with a primos as well (turbo dog I think) I didn't care for it as well. the remote range wasn't as good and the sound wasn't as clear IMHO.
Haven t heard the new ones
with foxpro you can put whatever sounds you want on it, sound and volume are good, customer service is great. you can hook up additional speakers, and your decoy to be run off the caller as well. though Ive never done either.
just my .02
