I have a ozone generator that goes in a XL plastic tub with my clothes. Big believer. The ozone from that thing permeates the clothes so much I can smell it all day. Its a larger unit made to treat 2000 sf, iirc. Kick it on when the alarm goes off, and it runs while I shower, drink a cup of Joe and eat a bite.
I'm a hygiene guy, shower before the hunt, unscented soap, etc. Also the Mando products are legit. The unscented one kinda stinks, so I put it on the night before, then shower in the AM. It really knocks out pits and butt as an issue, effects last a couple days. Still use one of the hunting brand deodorants after shower.
I have an old ozonics unit I take, generally run it for awhile after I get in the stand, especially on warmer days when I may have gotten warm in the walk in. Battery is old, so it only runs a few hours before it dies.
I can't remember the last time I was busted in the stand. I did have a doe get nervous a couple weekends ago. My son commented on the smell of the coffee I just poured in the blind, "can't the deer smell that?". Had a doe walk about 10 yards outside my open window right after (plastic walled blind on 10' platform), who started sniffing, then picked up her pace.
