lexty,
The Fury remote is using FHSS technology, which equates to longer range and more reliability when compared to the FX3 or Firestorm. However, if you are having an issue with the FX3, it may be caused by a number of factors. The range with the FX3 and Firestorm is very good, and should suit almost every predator hunter out there.
The Firestorms will begin shipping this week.
