some more observations on platform stands...
my 5'x5' blind heats up very quickly w/ a mr. buddy & one of those thermal fans, but, rarely have single digit temps during the deer season in oklahoma, so i rarely use it.
couple of yrs ago, had the heater fired up late november, had a nice buck come in facing straight at me, downwind, windows open but netting over the window. he stopped at 20 yds staring at my blind. took him 5+ minutes to finally turn & give me my shot. point is, either his nose wasn't working, there was no scent to be had, or he didn't care, but scent was obviously not an issue. Once again, it was all about the look of the stand. This scenario is common for me.
I'd also caution about going to tall with your stands. Mine are only 7 foot to the floor, but, that's the max height to have a shooting lane under the undercover of the trees. I built one on a 14 foot tall tripod stand that someone gave me, so i could put it on a field edge. Worked perfect by tucking it into stands of blackjack oaks to hide it, with 3 four foot stakes to keep it planted. Come back week later, it's down and tangled up in the oaks. Righted it, secured the legs pads with 2 t-posts & rope. 2 weeks later, it's down again, pulled the t-posts out of the ground. Got serious the last time with more t-posts and ropes. Now that it's not going anywhere, the wind destroyed my blind. I even slipped on the steps one time during a frosty morning, and almost fell off the ladder. 14 foot is too far for me to fall, so have a safety harness attached to it now. It was a ton-o work to be schooled like that, and I won't build another one that high for sure.
I know you all likely hunt deer as hard as I do. And like me, most of you are older w/ a ton of experience. I do believe when you all when you say you have scent issues when hunting out of these, but I haven't noticed any of it. These stands have made me a really lazy hunter, but, I do de-scent just like I do when bowhunting out of a hang on, and I don't like to use any scent at all, including ozonics.
Wait, I just lied. Got talked into trying EverCalm a few years ago, and I'll be damned if deer (and hogs) will hang around longer, and even lay down in the areas I've used it in, but, that's another topic!
