Activated Carbon Information

"My son shot his first squirrel last year, he was so proud. We were up north and its a 3hr drive. We got home and he showed it to the family and the dog jumped at it. I said to my son, bring her out on the leash when you see me out the window. I hooked the squirrel on a drag, took it around the yard and rubbed it up a tree. He brought the dog out and she ran along that trail. Mind you she was 1yr old by this time, but still a puppy. She over ran the trail like young dogs do, but she would find it again and ALWAYS go the right direction. She got to the tree and was confused and I patted on the tree to get her to put her front feet up on it and she did. She could then see the squirrel 4ft above her now that she was looking up. She barked like crazy.
Lets think about it.
This is a dead squirrel, not giving off any fresh scent of a live animal, just residual scent. How did she follow that track so fast and IN THE RIGHT DIRECTION?"

Ken I would imagine that even though we wouldn't be able to detect it but your beagle knew that the direction of travel because the scent starts to dissipate in minute quantities from the point you started to drag the squirrel to where you rubbed it on the tree. Enough for her to determine the direction of travel and as the scent intensified she knew her instinct was correct or she would have back tracked if the trail lessened at all. We wouldn't be able to tell but they can and will figure it out quickly. I don't have any experience with hounds but I have trained bird dogs and know many K9 trainers and while I agree that they are amazing animals, I think comparing a canine to a deer is apples and oranges in this situation. Their talents have developed in two totally separate ways and with distinctly different survival functions. Both have equally amazing olfactory functions but one is honed to track and capture prey and the other is to avoid and escape being killed. I think a more apt comparison would be the reaction of deer and say wild horses than a canine trained to track for scent.

While I personally feel the science is sound and that the technology works, I don't blame other people for feeling it is some sort of hype or quick fix because of the amount of advertising and marketing of hunting equipment theses days. I've said this many times on this site that confidence in ones equipment is one of the most underrated factors in hunting success and a confident hunter is a successful hunter in many cases. I also feel that John Eberhart feels that ScentLok clothing will improve hunters odds so therefore he wrote these articles to try and educate fellow hunters and give them information to improve their success in the field. Just as John has always promoted the saddle as the best way to hunt from a tree even though over the years many people have laughed and made fun of them with comments like tree diapers. Yet all of us are here because we feel to some degree that the saddle is an awesome way to hunt in and some cases feel it's the only way to hunt. To me the decision is easy try the product and if you feel it doesn't improve your hunting then sell it on Ebay. No matter what it's our personal experience that is the most important factor in our equipment choices not someone else's and if it works for you that's all that counts.

In my personal experience it has helped and some of the places I hunt I can't play the wind because I have only one stand location due to my states hunting regulations and can't relocate or move even if I wanted to. So in this case I try and reduce my scent footprint as much as possible and wearing ScentLok is one of the things that I do and so far I have experience positive results. The only way that anyone can decide for sure in my opinion if something is right for them is to try it and see if it works for them. I'm sure that I'm not the only one with that pile of hunting equipment that I thought was going to be the perfect thing but turned out to be total flop and now sits in a box in the basement. To me I can't think of anyway that wearing a carbon based garment could impede or hurt your hunt even if you play the wind or use some other method but in the end it's all about doing what works for you.

Good Hunting,

Roger
 
Bingo!

Scent control should never be crippling. I do my best to practice it in every hunt and I notice differences when I do or don't. But some hunts aren't built for scent control. In fact, even with scent control, some set ups are more prone to scent control failure than others regardless of wind direction, thermals, access,etc.

As much as I respect John, and believe me when I tell you John Eberhart has influenced my hunting technique (and success) more than anyone ever, I have a strong dislike for all types of scent control garments, sprays, or anything pretty much with the possible exception of Buck and Doe Tarsel Gland and fresh deer urine. I feel most of them are gimmicks, and the ones that actually work, work with nominal results.

I truly believe carbon activated suits are oversold as far as ability is concerned. But my primary issue is simply that it is impossible to eliminate human scent completely. So with that said, if a hunter was to eliminate 90% of his or her scent on a given hunt, would a deer, any deer, not be able to smell you if it was to pass down wind.

A few years ago, I was so obsessed with scent control that it literally ruined the joy of the hunt. I was doing it all, keeping clothes outside, isolated from camp smells, washing them in pine-sol, using special soaps and sprays before a hunt. Heck I was even lining the seat of my truck with pine boughs so as not to make contact with the seat cloth driving in. It got crazy, so crazy, I was stressing constantly and finally realized one day I wasn't having fun anymore. Another big realization was that I wasn't doing any better on the deer as well.

Here's the best part. I have a friend who is a veteran police officer in one of the bigger Michigan cities and he had gotten in with the K9 unit. In a demonstration of a dog's nose ability, which we would all agree is on par with a deer's nose, the department had four of its officers do an experiment. A square mile was located and sequestered for the event. these guys had weeks to prepare for this by scouting the land and being allowed to use anything and everything to kill their scent, cover it, to trick their own family pets. On the day of the event, four officers went into this square mile to hide from their own dogs using every resource at their disposal, including a running stream about 10ft wide. Four hours later, their dogs were released into the same section of land. The longest it took of the four dogs to locate their master was 15 minutes. That really did it for me. I take a reasonable approach these days and hunt the wind proper as the mainstay of my efforts. I stay out of stand sites and woods during contrary breezes or not hunt at all. The results for me have been steady over this timeframe, and better than when I was in the fanatic stage of my career. Just some food for thought all.

What did you wash in Pine Sol? That reeks bad

okay ive researched the effects of activated carbons personally and nothing scientific from my end just a lot of reading... and rather than buying a suit I have considered buying a few lbs of activated carbon dumping it into a huge Tupperware container then throwing a soda flat crate on top of it then leaving hunting clothes in the sealed bin for a few days on end... basically the flat will keep your clothes elevated off the carbon.. the scent would be absorbed and your clothing would be scent free upon removal from the bin... in theory it would work just haven't tested it and from what ive read the dry carbon doesn't need replaced like it does when used in liquid filtration... basically its a $200 scentlocker in a $60+/- DIY version
 
Your theory holds weight if the goal is only to have scent free clothing. The thing about ScentLok is it actively captures your human scent while in the suit. With your method, the scent from your body would still be escaping all through the hunt. That's the big difference.

Also- a lot of us take it to the next level and already use activated charcoal or carbon in our bins to keep our gear scent free and the gear itself masks "not eliminate" our odor while we're hunting.

FYI - Scent control garments are almost the same price as regular stuff if you know where to look. I've gotten a replacement late and early season suit (ScentBlocker Alpha and Knock Out) on eBay the last 2 days for $200 total and sold my old stuff. I just about broke even (<$20 out of pocket) on the deal and have brand new garments. Scentlok legacy locker is also a good place to look.

Goal is scent minimization not elimination. Activated carbon will never eliminate scent completely. Goal is provide a reduction that is less alarming to your prey. A whitetails nose is so good that there is always a fair amount of olfactory "noise" in the air. The magnitude of the odor needs to great enough to differentiate from the baseline odor and also of a quantity to cause enough alarm to "drink in" the alarming odor.
 
CHA CHING scent will NEVER be eliminated regardless and scent free clothing will help while walking into the hunting area... I feel once you are in the tree and 20-30ft high scent factor is degraded substantially I say this because while I am in this forum now I have only hunted from climbers and lock ons so far and carrying them in the distances I do ive gone in and gotten extremely sweaty and still able to harvest animals.. the higher you get the better I agree scent removal and minimalization is definitely key but elimination will never happen

First off hunters that spout off against activated carbon have no clue what their talking about, have no interest in researching activated carbon technology, are too lazy to properly care for it and do everything else in conjunction with it, and definitely haven't a clue what they spew about low heat regeneration.

I can give you a simple and visual example of how activated carbon regenerates using very low temperatures. Heat causes molecules to energize or in other words expand. We as humans can visually see expansion joints in concrete highways and is steel bridges amongst many other things. Trust me when I state that concrete highways and steel bridges never see temperatures over 110 degrees and let it also be known that the concrete and steel begin expanding on sunny days when temps are in the 70's. If the expansion joints weren't there the concrete would buckle from the expansion and the steel would bend if it had no expansion area to expand into. Human odor molecules and the activated carbon their lightly bonded to also energize under low heat and a percentage of the human molecules break free from the carbon and escape out the dryer vent making more room for adsorption again. Very simple and plain to understand.

A gazillion degrees is only required for total re-activation which is removing all bonded (industrial re-activation).




Not to stir up the pot any further, but I'm intrigued with all the info at this point and have a question directed towards John if he's still reading these posts:

In regards to using the Scent Lok face mask (And by the way I just purchased mine a few days ago) what are your thoughts on how effective the carbon is at Quickly absorbing the odors from our breath as we exhale through the mask? I mean we know that some 40% of human odor comes from the head, but can the breath really be absorbed repeatedly for hours on end without ever escaping the full absorption of the carbon? It's not like it's an air tight rubber seal or anything, it's still just an elastic band that can't truly lock in all the air going out right? And do you tuck your mask into your jacket even on the warmer days of the season?

Again, I'm just playing devils advocate on this, As I completely agree with the factual and scientific evidence of Activated Carbon.

I first want to say I very very much appreciate John and I've learned a ton from listening and read what he has to say about deer hunting.

Now having said that, I can assure you that the majority of your breath is escaping the mask and some of it may be being filtered. There is no way the a non-sealed mask is stopping the positive pressure and volume of air you are blowing out on your way to and up to your hunting position. Now maybe that's not even the objective. Maybe the objective is to simply eliminate as much odor as you can and short of a reverse gas mask you are not going to stop the majority of breath being exhaled long enough to filter it.

How often should I be washing scent Lok? How many times can it be washed before the effectiveness of the carbon is gone?

Met another guy who swears following Jim Braukers(extreme scent control video on YouTube)advice was a total game changer. Got me contemplating it again.

Scentlok recommends not washing it unless it has blood or dirt on it. I'd say the more you wash it the more carbon you loss in the washer making it less effective.

As someone who believes reducing your scent can make a difference, Jim B's process is at an entirely different level.
 
So another words useless in south Louisiana

I just brought scentlok last week cause they where on sale. And I won't to get a better scent control regiment it's hot in Tennessee early season I wear shorts and the shirt to the stand then put on my scentlok on take it off when I walk out
 
I just bought a scentlok jacket and pants on sale. Had zero to do with the scent control stuff but all the other features of the garment. I think the industry has brain washed us with all the scent control stuff. Almost can’t buy camo apparel now without some kind of scent control claim. Anyone who thinks they can doop a deer’s nose has lost the battle before it starts IMO.
