they got these new sell phones now. you put them on vibrate and they dont make any noise.
i was 35 ft up a tree and my wife was in a hunting treehouse we made. this game warden came down the trail, wouldnt have seen me if he had been looking up.
i called my wife and told her not to shoot the geezer coming her way. she said when he stopped about 20 feet in front of her she asked if she could help him, you know how a wife would say "EXCUSE me, can i help you?" he said well first tell me where you are,lol.
i had made a drag line with a blue plastic 55 gal drum, pulling sand out of the shallow end of the lake. the barrel had been laying there probably 2 years. the game warden said they were there to see if someone was baiting for bear. it was bear season and there might be 3 bears in Spartanburg county, but ive never seen one.
so cell phone is the way to go.
