I too have used the Chlorphyll tablets for 15 years and swear by them. In my area the wind swirls constantly from being close to the lake, hollers and creeks here, and I have had deer wind me, but be unable to identify me as a threat,due to the tabs, and other scent precautions. Hunt in the wind when possible, stupid not to, but when you cant do anything about it, use the ch. tabs, good scent control spray and clothes to your advantage. I have put a lot of venison in the freezer with these methods, that wouldnt have happened otherwise, and several were good bucks, all under 20 ydards. Use common sense and anything else that gives you a slight edge, I need all the help I can get, the game usually has the edge whereever I am concerned, hope this helps. Pm me for more info if I can help. Sam.
