No, they are safe. There is another big buck this year. Will put camera back out.Did you shoot one?
Have different kinds,Acorn,Bushnell and a few cheaper ones too.Acorn and Bushnell are excellent and the Toguards i bought have been outstanding considering they were 2 for £60 a few months before Xmas.
All do vids too and the sensors pick up very quickly.I have set for 1 pic and then a 10 second vid,which sometimes means i miss a good vid of the beast as it could be well into the shot by then.Probably better with either picking just vid or pic.
