Youve had your head in the clouds if youve missed the de-scents-itizing hype of companies selling ozone-generating products. Ozone, they claim, contains an extra oxygen molecule that attaches itself to other moleculessay, b.o. moleculesand changes their structure. Im eager to examine any deer hunting trend and, if necessary, flip it on its head. So I enlisted Chance, a highly trained police dog, to test ozones effectiveness. Ive watched Chances nose zip through every sort of no-scent solution and was fully prepared for an ozone rout. But thats not exactly what I got.
As a refresher: Our scent tests* are set up just like the training exercises used by K-9 officers. In the box test, police dogs are taught to find a bad guy hiding in one of six square boxes, spaced evenly across a large field. First, I sat in each box for a full minute, leaving behind a trace of human scent. Then it was up to Chance to find the member of my test team (hunting buddies Bob Borowiak, Tony Houdek, and Tom VanDoorn; and my father, Marv) who had climbed into one of the boxes. To start each trial, the handler took Chance off the leash, then ordered: Find him! At this command, I started my stopwatch and timed how long it took Chance to bust the hunter.
Analysis Dogs performing this drill are marked down if they bark at the wrong box, so its not unusual for them to check every oneeven if they get a strong whiff at one of the first. Chances head snapped around as soon as he passed Houdeks box, but he checked every box before racing back. Had he reacted immediately to that first scent (as a whitetail would have), Chance could have cut this time in half.
Setup To assess how a classic scent-control method would fare, VanDoorn, an expert whitetail hunter who swears by baking soda, took a shower in no-scent soap mixed with soda and then dressed in clothes washed in a similar combination, plus powdered with soda. He then rubbed more of it in his hair, on his socks, and in his boots.
Analysis Chance showed no noticeable reaction the first time he ran past VanDoorn, and he checked all six boxes. Even though VanDoorns trusted in-the-field system cheated Chances nose for a few extra seconds, the difference wasnt pronounced. I was a little surprised by this, given VanDoorns success at fooling deerbut not as surprised as VanDoorn.
Setup Before the test, my dad took a no-scent shower and placed a ScentPurge 50, an ozone-generating unit designed to infuse clothing with ozone (whitetailr.com), into a plastic tub that held his hat, boots, and two layers of camo clothing for 30 minutes. Dad dressed in these treated clothes just before entering the box.
Analysis The dog ran the entire course twice before marking Dads location. Though he did a slight head bob toward the correct box on the first lap, it was clear that the smell of ozone was confusing Chance. This was one of the most dramatic delays of Chances success in all the years weve conducted these tests.
Setup Borowiak took a no-scent shower and dressed in hunting clothes that hed washed in no-scent soap. He carried an Ozonics unit (ozonics hunting. com) meant for mounting near a treestand or in a blind, ran it for a minute inside the box before the test began, and left it on throughout.
Even the handler was stunned at how long it took Chance to find Bob. Again, the dog ran two full laps before choosing the right box, and his first bark was tentativelike a guess. This was the most shocking result in four years of testing. Wed put Borowiaks other no-scent regimens under Chances scrutiny before, and the dog had found Bob almost immediately. Yet the addition of ozone confused that nose for nearly one minute, which amazed everyone.
The stuff can rub your skin raw if you use it straight, cautions VanDoorn. So mix a few tablespoons with some liquid no-scent soap. When I used to shower with straight unscented soap, I could always smell a little odor when I was finished. I cant smell a thing when I mix in baking soda.
Use baking soda like any other powdered detergent to wash your clothes. Dry them, lay a few items in a plastic tote, sprinkle a layer of soda on that, put in another layer of clothing, sprinkle more soda, and so on until the tote is full. Then place an open box of baking soda in with the clothes and seal the tote up.
Obviously, your feet are one of the smelliest body parts because theyre constantly sweating inside your boots, VanDoorn says. If my boots are wet with perspiration after a hunt, I put them on a boot dryer and then sprinkle in some baking soda. Ive had very few deer cut my tracks since I started doing this.

I covered briefly the development of various types of reduction crushers of the gyratory family. Below you see a gyratory reduction crusher, which introduced the cylindrical top shell, flared head, and reversible concaves. Even with the older style of straight concaves, with which this machine was originally fitted, it represented a distinct step forward in secondary crusher design, and the later introduction of non-choking concaves increased its efficiency and permitted the use of finer settings than were originally allowable. This type of machine, although it has been superseded in the fine reduction field by more efficient types, still rates as a very excellent crusher for secondary crushing work.It has good capacity at moderate settings, is ruggedly constructed, and has, for comparable sizes, relatively large receiving openings, as compared to machines designed primarily for fine reduction work.
To show why this machine was a distinct step forward in secondary crusher design, it is interesting to compare the action of its crushing chamber to the standard crusher chambers already described. To make clear the fact that the machine had certain advanced features, even before non-choking concaves were developed, letsfirst show a diagram of its crushing chamber with the older type of beveled, straight-face concaves. It should be mentioned that these beveled concaves were not the very earliest type used in this crusher; they were preceded by plain, straight concaves, which utilized the full rated receiving opening of the crusher, but had the same disadvantage we noted in connection with this type, as used in the standard gyratory concentration of wear at the discharge point. The beveled type spread the wear out somewhat, although at the cost of some reduction in the effective receiving opening.
The distinctive feature of the design shown hereis the decided slope of the line-of-mean-diameters away from the center-line of the crusher, as this line runs down through the crushing chamber. As the volumes of the successive rings of material are functions of their diameters, as well as their areas, it is apparent that these progressively increasing diameters tend to offset the decreasing areas; in other words, the flared head spreads the material as it moves downward, thereby tending to minimize the ratio-of-volume-reduction. The actual compression-ratio in this chamber is about 1.5:1, which is lower than in either of the diagramspreviously discussed and very much lower than the case of the standard crusher with straight concaves.
This became the cone crusher and this departure from the older conventional design was a decided improvement for secondary crushing is apparent when we compare two machines of approximately equal head diameters, a logical comparison because the diameter of the bottom of the crushing head directly affects the area of discharge opening and, hence, the capacity of the crusher. This 10 reduction crusher, with its 40 head, compares closely, in this respect, with the 20 standard crusher, which has a 38 head. Using straight-face concaves, the permissible minimum open side settings are 1.5 for the former, and 3.5 for the latter. With non-choking concaves these settings are, respectively, 1 1/8 and 2 1/4.
Non-Choking Concaves To show the characteristics of this type of crusher when fitted with non-choking concaves we have prepared a diagram of the same size machine so equipped. You now have the cumulative benefits of the flared head and curved-profile liners. There is a marked reduction in the number of strokes required to shift plane O down to the discharge level; the choke-point has been raised, and the ratio of volume reduction is lower (about 1.2:1). There is a decrease in the effective receiving opening, as compared with the straight-face chamber, when using full-curve, non-choking concaves, which is the type shown in our diagram. This effective opening is established by the maximum angle of nip; therefore it varies somewhat for different materials, and in different sizes of crusher. For this crusher 26 deg. was chosen as the governing angle; about 28 deg. is the conservative maximum for the largest machines of this type.
High-Speed Crushers So far, all of the crushers we have been discussing have been of the low-speedclass; that is, with eccentric speeds ranging between the approximate limits of 100-200 RPM. It is customary, as before mentioned, to rate such crushers at their open-side discharge settings, because there is a definite relationship between these values. Most modern crushers, designed for what may properly be classed asfine-reduction crushing, are of the high-speed type. The eccentric speeds and shape of the crushing chamber in the machines of this type are such that the maximum one-way dimension of the product particles is established by the close-side discharge setting; consequently it has become customary to rate these crushers at this setting.
The Newhouse crusher was one of the early developments in the highspeed class of fine-reduction crusher incorporates several unusual features, at least one of which is unique in crusher design. The eccentric is direct-driven by a vertical motor mounted above the spider, the drive shaft running down through the hollow-bored mainshaft. Speeds range from 480 to 580 RPM, depending upon the size of the crusher, and upon the frequency of the electric current. Eccentric throws, as compared with those of the crushers we have been dealing with, are relatively low. This combination of small throw and high speed results in a very uniform product with a minimum amount of fines for any setting and ratio of reduction. A unique feature is suspension by means of cables, eliminating the usual foundation, although the crusher can be set on a foundation where required.
This crusher is usually furnished with full-curve, non-choking concaves, which are reversible in the top shell. These concaves are of the same general contour as those shown in the above diagram of the reduction crusher chamber and in general the crushing chamber is similar, except that the chamber in the Newhouse crusher is somewhat deeper and, consequently, the head does not have as pronounced a flare. The important difference in the crushing action of these two machines lies in the difference in eccentric speed. That of the Newhouse crusher is so high that no material can drop through the almost parallel zone just above the discharge point without being caught between head and concaves and broken to a maximum oneway size closely approximating the close-side setting.
This crusher can be set somewhat closer than comparable sizes of the reduction crusher previously described. Although it cannot be classed as a fine-crusher it does belong to the fine-reduction class. Furthermore, by virtue of its large receiving openings, it rates as a machine for secondary reduction work. When so used it is usually fitted with concaves of the non-reversible, non-choking type, which are designed to make use of the full rated receiving opening of the crusher, although they sacrifice the feature of reversibility which permits wearing both ends of the concaves.
MASON CITY, Iowa,July 24, 2018/PRNewswire/ Ozonics Hunting, the industry leaders of harnessing the power of ozone and oxidation technology through active scent control while afield, have filed a patent infringement lawsuit against Mojack Distributors, dba Scent Crusher and seeks an immediate injunction to stop Scent Crushers infringement.
Founded in 2007, Ozonics proprietary and patented technology covers its portable ozone generators designed for use by hunters in the field. Since filing its first patent application in 2004, it has invested significant resources to develop this patented technology. This innovation literally created a new product category in the hunting industry and Ozonics has diligently and successfully enforced its patents and has declined to sell this proprietary and patented technology to any third parties. Instead, as the Patent Act allows, Ozonics is the exclusive provider of in-the-field ozone generators for hunters.
Ozonics brings its patent infringement lawsuit after Scent Crushers recent announcement of two new products for 2018 the Field Lite and Field Pro portable ozone generators designed for use by hunters in the field.
In the motion for preliminary injunction, filed inthe United StatesDistrict Court for the District ofKansas, Ozonics asserts that rather than blazing its own trail of innovation and securing patent rights to protect that innovation, Scent Crushers imminent emergence into the market is based on a concerted and deliberate decision to unlawfully take what it failed to obtain through proper means.
The filing further states that Scent Crushers deliberate, wholesale, and systematic campaign to rip-off Ozonics technology must be stopped. Such illegal conduct makes investments in innovative technologies costly and pointless and will serve to encourage others to knowingly violate hard earned intellectual property rights when they feel the monetary upside justifies it.
We will continue to invest heavily in producing the best possible active scent elimination products on the market, stated Ozonics FounderScott Elrod, and we will continue to protect these patented inventions from being stolen by others who are looking to unlawfully capitalize on our significant physical and financial efforts. Our goal has always been and will continue to be to create products that revolutionize the way big game hunters combat human odor the greatest single factor of success in the field.
About Ozonics:Founded in 2007, Ozonics is the industry leader in active scent control and has the first and only in-the-field ozone generator that has been designed to blanket human scent with scent-destroying ozone. Unlike any other scent control product, Ozonics continuously deals with the scent in your hunting area by using ozone to eliminate, alter and reduce scent molecules making them undetectable by deer and other scent-wary game.

We tested used their products some last year when we were trying to decide between Scent Crusher and Ozonics. We were not able to promote both because their categories are very similar. We decided on Ozonics because we felt it did more for us not just the garments (though it does that with the DriWash Bag), but also in the field. However, we did feel that the Scent Crusher product worked to refresh clothing, it just didnt do anything for us in the field like the Ozonics does. Have a great day. (10-4-16)
