This is just my experience as well as learned knowledge.
I have had virtually zero success with calling on pvt land (2x) and even less on public (0% success). I hunt it two heavily pressured states.
MI which kills alot of bucks and has an enormous amount of hunters, FL which has essentially unlimited bucks, and a very long season
Calling? They really have no reason to come the ratio is so askew in the bucks favor. Although, if you hit peak rut, like when some does are starting estrus, I do think calling can be successful, but a lot relies on timing and your herd.
Scents? I've used everything I can think of. Aerosols, doe pee, buck scent, tarsals gland. Suspended from trees, drag rags, I can't imagine how many I have tried over the years all with very very limited success.Once again I think this too is dependent on the buck to doe ratio.
Best success I have had with anything was 1) mock scrape's made with my own urine (had visual queue's too) and it was also at peak rut (IE does coming into estrus) 2) Smokey's preorbital
Currently I have 2 years of using Smokeys and I cannot tell you how many deer it attracts to the branch. I start using it early summer (after I scout and determine "where" the deer are), within 24 hours I get deer on camera. Is it attracting them? Or am I just introducing a new scent they find curious/alarming and they just have to check it out? Dunno yet, but I do know that I haven't caught anything else on camera like that using other 'scents'
Just my experiences.
