Seems to help when after many years of seeing deer while out hunting then the deer just slowly start to disappear till the point you don't see anything and spend 20 days out hunting you wonder if there are any deer still around. There is they just changed the time they are traveling from morning, mid day and before sunset till most well after dark. Seems that the States plan has changed their patterns and thus you know deer are around just when you are not out hunting them... Seems to help keep some interested when you hardly see any deer year after year. The last 8 years we have gone from seeing a lot to seeing maybe two fawns for 30 days of hunting, it is a good tool to help with the boredom also you know there are deer near by now you just have to be at the right place at the right time but that is not in your favor with the high number of Antlerless Permits they have given out the last 8 years cut the population in half if not a 1/3 of what we were seeing. They cutting back on them now but it is a little too late too many taken...
I build my own, have two digitals and have parts for two more to put together. A lot of fun checking all the pictures and seeing Bucks, Does, fawns and even a Black Bear now and again...
