I have a WD-2 and a WD-3 I have had good luck with the WD-3 so far Great pics on a trail no feeder or lick. I just Placed my WD-2 Saturday. I am very unsure about the location, as I was in a hurry. Had kids with me and they were less than happy at the time but I will see what I get. I am going back Thursday ( weather permitting ) to check it, and move it if need be. I will let you know how it works out. Tests at the house seemed to work great but the field is a totally different animal.
