I originally had a FX3. After fooling with the remote too much and losing some dogs in the process, I sold it and bought an NX3 that I've used for the past 2 years. I made all my own 20-30 min sequences and it's been a great call for me. I really liked just sitting back and letting my sequences rip while I paid attention.
A few months ago I decided to get another FX3 for the remote. So, now I have them both. Thing is... the remote is unreliable. If mine "hits" wrong (and I don't have a clue what that IS), it'll stop the call dead and I have to walk up there and turn it off/back on. Back home when I try to figure out what went wrong, it works perfectly, up to 80 yards! I don't know the deal is.
I should sell one of these as I don't need two FoxPros. The FX3 can be used just like the NX3 with my sequences and maybe I'll get the remote figured out. OTOH, the NX3 is reliable and I find that I pay a lot more attention when I don't have the possibility of a remote to fuss with. At this point, I'd probably sell the NX3 but I sure don't see the remote as "essential".
Shoot me a PM if you're interested in either one of 'em.
