I took my new wildfire out for the first time yesterday and called 6 different sets with no luck. I had new batteries in the remote and the unit, but the remote was very inconsistent to say the least. It was about -10 F with snow on the ground. I had the caller elevated off the ground with a small tripod. Even with a perfect line of site at 100 yds away I could barely get the remote to work. At 50 yards it was better, but still not perfect. It doesn't work very well to hunt when you are focused on the remote working, not being able to mute or change volume when I wanted to, spending time trying to get to a location where it will work, or lifting the remote above my head to get it to work. Very frustrating. So did I get a faulty unit or do I need to sit right beside the call to get it to work right? Which kind of defeats the purpose of the remote e-caller.
