Like most of you, been deer hunting for really long time (40+ years). Over the years, I've bought all the stuff from: Tink's 69, skunk/fox/coon cover scents, scent lock clothing, to ozonics. I've tried it all.
As a bowhunter, it took many years of experience to figure out proper stand placement, due to winds and sun, and how thermals work. Of course I wash my clothes unscented, use a pine branch in the bag i keep my hunting clothes in, don't put on my boots until im on hunting ground, etc...
Over the years, with the plethora of scent tech that's come out, with most of it making its way into my hunting routine at some point, I've kinda come full circle and ditched it all. I found myself setting bow stands up with less regard to the wind because i had an ozonics unit hanging next to me, and my clothes wet from spraying scent control all over. Eventually, It was all becoming too much to f*** with. Pretty easy decision when everything I had tried over the years had minimal to no effect, yet i was wasting time and money trying to make it work. (only product i ever found that had success was Evercalm) I've found I enjoy hunting more with less in my backpack.
IMO, Nothing beats proper basic scent control combined with proper stand locations and entry/exits.
**side note: never had a buck chasing spook to my scent either. On the contrary, during the rut, I've had nice bucks come in my lap from straight down wind more times than I can count.
