I have the FX3. It can carry 32 different sounds, remote control, etc. I have been very pleased with it so far. The sounds that Foxpro has to offer has been great. On one night hunt, however, the sounds were altered somewhat and I'm contributing that to cold weather. It was between 0 and 5 deg. when it happened. Hasn't happened since so it may have been a fluke. Hope this helps.
