Can it be done... scent proof blind?

[Farmsteader]

Seen folks put a tube 20ft up higher in the tree, couple that with some natural draft from a heater, its a decent setup too.

300ft of that tube costs more than the shack.

I wonder if you put the exhaust into a box or mound of leaves or recently cut pine branches, would the scent be a bit more masked?

Yes getting you scent up high does work too. The platform on this stand is at 24 feet and I have had deer directly underneath it. This is more of a gun stand so scent control isn't so important.

Nice work!

How far did you sink those posts in concrete?

Are the 4 main posts 8x8's or 4x6's?

I did 2 pours on the concrete. The first one is a foot thick and 2 feet round with rebar joining the second 3 feet in a 12 inch sonotube. I anchored the 6X6 posts with some concrete brackets from Menards. I had to make a form to hold the four brackets level and straight for the last pour. The whole project took me all of last summer to get this far. This year I got the widows in and have it sealed up tight enough to keep the bugs and critters out. Last winter I had a squirrel make a nest with babies inside.

No there is no filter, the enclosure is 100 yards away through a red pine plantation. I have seen deer exit my food plot heading towards the exhaust and get spooked by my scent and come running back into the plot. My only concern is the noise of the air moving through the vent in the blind. It's just a steady low hum like what you hear from a heat register. Once and a while I will have a deer walk through the draw and will look right at me like it's alerted of something. Not sure if it's the noise or something else. I bought some sound absorbing foam panels that I plan on making some kind of baffle to minimize the noise.

You can make the exit of the box have some louves pointing down, like window blinds. You can also mount the fan to something vibration absorbing. Mount the fan to a small square of wood, then mount the wood to some rubber sheet or tire innertube then to the inside of the box. You could also take a screw and thread it into the wood where the fan would be, then hand a 1 or 2 oz fishing weight off a rubber band. Would absorb any vibration causing sound from the box surfaces. Just piling some dirt on the side of the tube might quiet it down too.

Explain to me the mound that it appears to be on? I'm assuming you dumped it there to make the stand even taller compared to the surroundings. Did you pour your footings then dump the dirt on?

I couold be wrong, but I don't think the sound of the fan it self is what I'm hearing. I think it's just the sound of moving air through the tube. I do have the tube buried for about 20 yards from the stand and also under a road I use by the fan. You would think the dirt would stop any vibration of the tube it self and a 100 yards is a long way for the sound to travel against the exhaust.

The spot I picked for the stand has a little slope to it so i dug down a little on the high side and filled in the low side for the first pour then built it up for the second pour. Yes you were right , during my thought process on how to do the concreate I was thinking higher is better.

We very seldom get winded from a box. It does happen but not often. I attribute it to our clothes being treated in an ozone room. No ozone on stand but our clothes reek of it.

I ozone my clothes too. If bad wind I’ll use ozinator in box. If good wind I don’t.
