I have owned and used FoxPros; AR-4, 416, X1-A, X1-B, Furry and now Krak Two. Also three MA-21s and my old standby, a WT KAS 2030MS. And three or four other brands. They all called predators. (-:
To my ears my Krakatoa 2 and the WTs are very close in volume and sound quality. All three (K2, MA-21, 2030MS) blow away the other callers I have used. The TX1000 that comes with the K2 is [beeep] sweet! I always had trouble with the other digital remotes, this one works like a champ for me! For me the battery system on the K2 is far superior to any AA system I have used. Easy/Fast to charge and they last and last. The K2 is significantly larger than my little 2030Ms, that I do love. But I find the K2 is easy to carry and has great balance. BTW: The antenna on the K2 is very simple and unobtrusive.
I figure with the WT sounds on my KAS2030MS and the FoxPro sounds on my Krakatoa 2 I have the ability for a change up when necessary.
I expect the CS24C with a K2 TenPak would also be tops, but with predators to call, I got impatient and popped for the K2. (-:
Oh Yeah...It's true, "the CS guys at FP are awesome!" But then Patricia and Bill have always been great to work with for me also.
