we had some ducks killed thursday night so friday afternoon i moved my tower and i was in place by 11pm by 3am i could not stay awake so called it a night. the next day dead ducks again so it was another early hours fox. last night set my alarm for 2am and i got to the field by 2.30am scanned the field with NV saw nothing so i climbed the tower, not that quietly as its a steel tower a quick look round and there's the fox a good sized dog with his back to me eating a duck about 75 yards away. a quick swap to rifle and an easy shot back home by 3am. i know ducks make a lot of noise but iam sure that fox was deaf.
