There are too many features and choices in the e-caller arena for me to even separate current and past models based on them. What features, gadgets etc. do you believe and things that you can't or won't go without?
i mostly want a caller to respond to the remote button pushes every time. nothing worse than getting set up and then the remote will not operate the caller. the foxpro callers with fhss remote capabilities work about the best for me in that department.
most any caller on the market will call predators if they are in the area and willing to respond on that particular day. even the cheapest and crappy sounding callers will bring them in if everything else is done correctly. but they must work when you need them to.
Dependability in cold weather, clarity and volume of sounds, remote that works and lights up. Doesn't feel like you are hauling around a car battery. I also use a cs24c
