I ended up selling my JS preymaster 4 this year, seems like hunters specialties doesn't want to produce all their sounds to digital. I ended up buying the spitfire. the unit has one speaker similar to the front speaker of the fury, same size. unit is powered by 4AA batteries and remote with a 9v. I ordered 24 different sounds than i already have so now i have 124 foxpro sounds (should be enough for now) we download the new 24 sounds to the computer to back them up, then i loaded them onto the fury. then i went through the list of 124 to see which 24 i wanted on the spitfire, picked 21 for coyotes and 3 for crows for this time of year. the spitfire speaker in not as clear as the fury, the is a slight humming noise in it when a sound is not playing, when a sound does play it is crystal clear. i at first thought it wouldn't be loud enough but there is a big sound difference when you get up to 4 and then 5.
one thing the fury can play 24bit sounds but the spitfire cannot, so some of the ones on my list i cannot use on the spitfire. when you pick your sounds for the spitfire they must send them in 12 bit because i know i picked sounds that were 24 bit. i don't understand that. also the spitfire will take mp3 files i did load js gf pup and it does work. the remote on the spitefire is easy to work, all in all it will be a nice call to have and use, i like that i can pick and choose what sounds i want on it at any given time.
