im interested in this too. its been around along time and makes sense that it would work. Mock scrape or real....hang it and it drips in the daytime only. I would think it would be pretty successful...but I havent heard a ton about it
I’ve used them a couple different times. Ive had about the same results with mock scrapes with no dripper so I’ve just started using that method. I Start in late summer, and just add a little pre-orbital gland or something similar to the licking branch every now and then as I check my cameras
I've used them and set up a camera. Does do come to it but only have after dark pics. Never had any success on hunting over one. I stopped trying years ago. But good luck to you.
