Was out calling today in 0 to 10 f weather. Foxpro fusion with foxjack only lasted 2 sets around an hour total before it started to cut out at higher volumes. These were brand new batteries I had put in last night. Assuming maybe these batteries had sat on the shelf too long or something we repläced them with new ones from my brothers stash that he uses on his WT-MA. End of second set on the replaced batteries, fusion call starting cutting out again on pup distress 28 volume level. Is this battery performance normal for this call and temperature? Is the decoy eating up the batteries? If the call was kept warm some how would battery performance increase big time? Most of the sets, volume was between 20-40. Needless to say after the second time the call starting cutting out we switched to the WT to finish the day.
