I live on a farm backing onto the hillside.
Every winter I put out a carcass on the slope behind the house and knowing that foxes tend to put carcases down hill; I loop some fishing line from the carcass round a post & then down through the bedroom window. I then attach this to the pull cord above our bed. I then attach a fishing bite indicator bell to this. (I have a very understanding wife!)
When the fox pulls on the bait (In this case a dead turkey) the bell sounds; I creep out the front the house & rest the 6.5 x 55 on the roof of the pre stationed car, turn on the lamp (not even neccesary in the snow) and a 95 Vmax is sent on its way.
Last night my wife rang me to say that a fox was pulling on the bait as I was returning from lamping the lower fields. A sweep of the lamp did not reveal anything however and the line was still tight so I did not think that it had broken. Thinking that the line was still attached to the turkey I left it be. In the morning I found the 1/2 eaten turkey 1/2 way down the field. The line HAD broken but had snagged up on the post so had not gone slack. The fox had been there again in the night without me realising it. I am going to get some stronger fishing line today and will let you know how I get on tonight.
