A skilled mathlete , autodidact polymath coyote hunter in the Texas panhandle ......... my respects. Thank you Todd .
Very interesting. In my experience, there are "Dial" guys and "Hold" guys. The Dial guys twist knobs and the "Hold" guys look for impact and adjust to that point in the glass.
The Dial guys tell me the reticle is too complicated. But I'm a ( OLD!) hold guy, so this seems much easier. At my age it's much easier to see the impact and the reticle than it is to attempt to refocus on the dial and then go back to the glass.
You brilliant bastard. Also, i was on the fence weither I was going with this or the mil-xt. Tremor 3 it is!
Well crap... I just found out there is a Tremor5..... Now what!!!???? Lol
Im a little late to the party but man this is good stuff!
Todd Hodnett is the Best, Great Video👌
Glad you enjoyed it!
Much more info than I was able to figure out when I got mine. Ended going back to the h59.
The T3 is a 59 but I removed the marks below the secondary stadia lines and put in the wind dots. Faster and easier to use calling wind
I don't understand the calibration process even after having watched this a few times. I think you need to do a couple of videos on this.
The easiest thing to do is just use the FREE Horus Ballistics App. All you have to do there is put in atmospherics and it automatically gives you the wind dot value!
I absolutely love my tremor 3 atacr
Always a pleasure to watch your work!
hold method is good because it saves the turrets, many have the illusion just because you have a night force scope that you can turn turrets and they always reset but they never do because the wear, though very small and undetectable still degrades even the best scopes, i think horus scopes are a great idea and very underated and those involved with these scopes are geniuses and reticle gods. scope adjustments need to nest and settle but constantly spinning knobs only degrades its repeatability and scopes like horus provide a solution for wear and tear but using "hold" instead of "clicks"
Absolutely awesome Todd. Using the Tremor 3 on my NF Beast mounted on my 7.62 OBR.
Nothing short of incredible.
How about putting on a Tremor 3 class through Accuracy1st?
We apologize for the delayed response. Due to new ownership, there was a delay in social media interaction. It sounds like you have quite the setup! You may check with Todd (Accuracy 1st) with this being a year ago if he has some specific based Tremor 3 classes. Have a good day.
Be happy to help. contact me at Todd@accuracy1st.com and I will be happy to answer any questions
I am new to this and I would like to know how do I come up with my BC for my rifle? I am using a Christensen MPR in 6.5 creedmoor.
@@hocakwowonk Your bc is going to depend on which bullet your shooting. It's not something you figure out, you just need to research it.
Forgive my ignorance….once we have the wind dot calibrated, how do we take account for the actual spin drift and the wind call?
holy cow!! that was way over my head, and above my pay grade. that is why I never got into precision shooting!
I have watched this video at least 100 times. And I still am not 100% on getting the wind dot value. Are these steps correct: 1) using a kestrel or other software Find distance for your weapon where 4 mils is the elevation hold. 2) find the wind speed at 4 mils that equals or is as close to .95 mils as possible with direction being “full value” or 90 deg if target is 0 deg. Take that mph and divide by 2 for value of all dots. Is that correct?
All values and ranges are in MIL RADIAN and METERS based off a 100m Zero Distance using preloaded gun data for common-caliber rifles.
1) Power on your Kestrel and double-check that all adjustments and ranges are in MIL/Meter values.
2) Go to the ENVIRONMENT tab in your Kestrel and turn off Spin Drift.
a) Remember to turn Spin Drift back on after you calibrate your Wind Dots.
3) Go to the WIND tab in your Kestrel and input a full-value wind. (3:00 or 9:00 wind direction)
4) Go to the RANGE CARD tab in your Kestrel and find the range in which 4mils is your elevation hold.
5) Adjust your wind value until you have as close to a .95mil hold at 4mils elevation as possible.
a) Note that the value may not always be exactly 4mils elevation and 0.95mils wind. For example: Using 175SMK .308 at my atmospheric conditions, I have 4.09mils at 520meters with 1mil of wind @ 8mph.
6) Once your wind value is determined, cut the value in half and that is your calibrated Wind Dot value.
a) 8mph wind value / 2 = 4mph Wind Dot.
The reason you cut your wind dot in half is because you are calibrating the second Wind Dot. There are two Wind Dots within .95mils. Hope that helps
Horus Vision yes! Perfect. I needed it in simple steps. Thank you!
@@KetemaHarris Happy to help!
Hmm... looks great... so you nul out spin drift and coriolis with a small windage turret adjustment then use the wind dots strictly for wind hold estimation?... this ought to increase ones rate of fire for engaging multiple targets at different distances from a single position like at a match stage... Are these reticles commonly used by PRS competitors?
Horus Reticles are widely used within PRS, as a matter of fact they are the Official Reticles of PRS
All of the wind dots line up perfectly on the 1 mil line. Why wouldn't you want to use that line to calibrate instead of the 4mil line? Thanks for the video, love my Tremor 3 scope.
The dot locations on the 1 mil line are not nice round numbers where the 2nd wind dot at 4 mils is a nice round number to use. The easy button now is just using the wind dot calculator in the FREE Horus Ballistics App.
Het Todd, I am new to long distance. Although I am new to this I get BC and velocity and certain aspects of what you are talking about but this is still over my head at this point. I just purchased a scope with the Tremor 3 . I am pretty confidant with dialing up but wind holds using this reticle are like another language right now. I need to start from the beginning. Any videos you might recommend or books? Is there a chart somewhere that lets you know what all the hashmarks, dots represent? Thanks for your help.

Here's a quick, easy, and accurate method for wind counters with virtually any BDC/ranging reticle, just calculate the MOA wind constant for prevailing weather conditions, do in-head wind counter equation, and adjust sight or favor from reticle with range card support for proper adjustment/hold in MOA or mils. Here's the formula: target distance in yards divided by 100 times wind value in mph divided by MOA wind constant. Example: .308 175 SMK at 2610 fps in standard atmospheric conditions shooting at 1000 yards the equation is 1000 yards divided by 100 times let's say a 10-mph wind divided by the constant of 11 as determined from prior trajectory calculation equals 9 MOA, 2.5 mils, or 90-inch favor.
So if I sight in a 308 dead on at 300 yards with 175 gr SMK, rather than dead on at 100 yards, will the wind dot’s still work?
It seems that since would less holdover at say 600 yards, the wind dots would be worth more than 4 mph.
Can anyone offer input?
Thank you.
Awesome information all right, I went to one of his courses all right and it was very informative allright and I learned more about a similar reticle allright, now I can utilize the same methods when shooting animals allright. It’s a really good bit of I formation allright for a guy that studies shooting better than snipers allright.
But me personally I picked up his word of saying allright a lot in class..maybe I have OCD or something but counting how many times he says “allright” I paid attention more...27 times in this video...
But I got the info for my .300 Win Mag
Alright then!
Alright you got it.Ha
Muy buenos dias exelentes ayudas te pediría el favor de la traducción en español seria exelente bien dia muchas gracias
The thing I'm not getting after watching this is: you're talking about the 4th line. How does that line relate to the ballistics of a particular round at a different range, or, the other lines in the reticle?
The 4th line and 2nd dot is just nice number at .95 mil to use, you could use others but for most setups the math works out well to start there so it's not a special line in any way, just an easy one to calibrate the wind dot value. Once you have that value every dot is the same value at any range as long as your equipment setup is the same.
What is the significance of the fat 16 mph dots? What makes them special?
The wind dot value there is 0.95 mils which is a nice "round" number and it's low enough in the grid to give you enough fidelity with the wind speed that gives you that value to be accurate.
What do we mean by “calibrate”? And why are some dots bigger than others? Thanks
The ballistics change with atmospherics and with BC/MV so the value of the wind dots will change so you'll have to calibrate to know what their value is. The larger dot is just to make it easier to count how many wind dots you're using.
Serious question: So i'm turning off spin drift on my kestrel. Dialing it on my scope. Then holding the mph in the reticle. How is this a better system when shooting movers. Now i'm holding wind and mover lead?
"Better" is always a matter of opinion but many people find it much faster, particularly when needing to rapidly engage multiple targets at various ranges and speeds. Here is a video showing how to use with wind dots and time of flight for movers: ruclips.net/video/d5Ry8DdcF1I/видео.html
I wish they put this in a acog for machinegun Kentucky windage just become more fast and accurate with this reticle 😊
This reticle works perfectly with the examples of cartridges he has given, but when used with my actual load data the error is much worse.
Using the methods shown for my 260 by the time I get to the 7th mil line or 830m, the amount of error is over .2mils which is half a foot. Whilst it is actually not too bad, by the time you add wind speed estimate error and angle of wind and all the other factors you are easily looking at a miss by a foot or more.
I think this reticle looks good when engaging lots of large targets quickly, but considering the premium price this reticle adds to a rifle scope and the fact that you would still need a dope chart or reticle chart showing which range the mil lines/wind dots are accurate at, I'm not sure it's worth it.
We apologize for the delayed response. Due to new ownership, there was a delay in social media interaction. If you can give us a call we can discuss this in further detail and try to come up with a solution. (866) 568-2926
We use the reticle every week and have zero issues on any caliber. We have shot 50 cal to .22 and everything in between. Most problems are the actual wind call that makes us miss, not an error in the reticle. The reticle can not have an error because you calibrate it to your ballistics and DA. That what the TOF dot does
Also I personally shoot a 260 as it is one of my favorite calibers and have zero problems. We shoot in high winds all the time, so if there was an error it would be multiplied
What app or system do I use on my phone for this scope sight?
Any ballistic solver will work with the TREMOR3 reticle but the easiest will be our FREE Horus Ballistics App. You can find all the details at www.horusvision.com/horus-ballistics-app/
@@HorusVision I just downloaded it thanks, saw it in another video. I think for a leupold #173298 the windage and elevation click value is 0.1 mil but idk the click value. Also for bore height it's that center of the scope to center of the chamber?
@@slruiz1986 if scope turrets at 0.1 mil per click that's what you put in the app. It doesn't impact the output so not required. And bore height should be center of the bore to center of the optic.
Is this operating off of the assumption that you’re zeroing your rifle for 100 yards?
That is correct.
Exactly, I don't understand why so many manufacturers of long range rifles assume that the customer is using 100m or 100yd zeros. If one zeros at 100 then by the time one goes into the scopes highest magnification needed for a long shot it's out of viewing angle. One cannot merely use a click adjustment because then Z is no longer at 100yds (or otherwise near the peak of trajectory) and wind dots become miscalibrated [useless].
I zero my .308 (175gr) way out to 751m 😳. This keeps my near max target range (1km) within 6 mils @32×. The downside is I have to zoom out for more than a 2mil wind adjustment, OR click it up to zero for up to 6 mils wind adj. Click adjustments isn't ideal because click adjustments don't do very well returning to the exact same place.
For near side that means 351m to 751m is viewable at 32× & w/o any click adjustment I can zoom out slightly for the additional 2.15 mils needed to bring the trajectory peak 82m into view. Which is fine, one doesn't need a massive 32× at such a short distance nor will there be huge wind adjustment either.
All that said, I don't take deer below 1k ft.lbs, past 551m, or 3.43 mils above my scopes zero; which is 4.72mils below the trajectory peak. So if a person is only using their rifle for hunting a Z=100yd is acceptable (note: bigger game require even more energy to dispatch ethically thus a shorter range is required anyway).
To go the otherway, I'm using a .17cal to take rabbits and similarly sized where the the combination of heavy wind influence, quick drop in energy, and accuracy of the rifle/ammunition isn't effective beyond 150-175m or just a couple mils from peak 56m.
In summary, the Tremor3 reticle 100yd zero is probably fine for MOST hunters who don't engage Precision BenchRest (PBR) marksmanship. Would I use that zero in the military, NO; PBR, NO; (if I did) coyote hunting, NO (I'd also use a different round)!
That said, I'm not spending $2k-$3k or more on a scope for my deer rifle.
I do enjoy my scope with the Tremor3, but I don't use these wind adjustments. I do wish my scope had more mil illumination in the upper half of the reticle; where I would use it.
Update: I discovered my Scopes ability to adjust the stop point to get the last mil adjustments. This does give me the ability to Z@100yd (now at 81 clicks w/ .1 mil clicks). Still the problem persists that if I Z@100yds, then I can't use wind dots past ~600m
🤬 seriously who calibrated the design for 100yds on a MIL-dot scope with 0.1 mil adjustments? You're driving a mortarman crazy. Stick with metric or Imperial measurements, metric preferred.
I have the latest/last version of the Atragg software. It's setup for plotting wind numbers for the Tremor 2. Is this the same for the Tremor3? If not, is there a multiplier to apply to the Tremor 2 numbers to get Tremor 3 numbers?
Thanks!
It is the same for Tremor3. Just be careful when inputting your variables and you'll be all set!
Why are you using G1 BC’s and not G7 or custom Frag model? Is that just so everyone can follow the directions together?
We apologize for the delayed response. Due to new ownership, there was a delay in social media interaction. You are correct for simplicity. Have a good day!
We talk G1 and G7 just to have something everyone can understand and compare to in the setup they might be using. I always us CDM's as they are made for the bullet you are using. Not math made for a drag model that is not you bullet. But your correct. Just for comparison is the reason
Can I zero my rifle in yards and do the calculate for wind dots instead of meters? Local ranges only have yardage signs for 100, 200 etc. Thanks
Makes no difference, just find you chart. go to 4 mils and up the wind until you get .95 mils and follow his instructions, cheers
Joel Blackburn thanks man for the help 👍🏼. Ordered the scope 6 weeks ago. Arriving next week. Can’t wait!
Yes you can work in yards.
Arright.
Excellent! Thanks.
Can these mph wind dots translate to km/h doing the same calibration but using km/h instead of mph?
We apologize for the delayed response. Due to new ownership, there was a delay in social media interaction. If you can give us a call we can discuss this in further detail and try to come up with a solution. (866) 568-2926
Yes, just use km/h. You can make up your own measurement if you want haha. If you have a kestrel it's really easy.
Yes
Drinking game, take a shot every time he says alright. Double when he says alright so.
Why use the 4 mil line?
Just because it is a wind dot with a nice round number, the others are long strings of decimals. It's much easier to use the automatic calibration tool in the FREE Horus Ballistics App or on our website at www.horusvision.com/reticles/wind-dots
This was the way we use to calibrate in the past. The reason of the 4 mil line was resolution per mph. Now we just use the horus app or the kestrel with the Accuracy1st page which does the calibrating for you. Much easy now than when we made this.
With this video I understood that my IQ is less than 14..
You can just use the Wind Dot Calibration Tool in the FREE Horus Ballistics app and it's much easier! www.horusvision.com/horus-ballistics-app
Thank you, yes, i have Leupold mark5HD with H59 reticle. whoever i can’t understand and use those many options.. but this reticle is absolutely best of best reticle i ever seen..
Each dot is 3 mph with my setup... shooting 22 lr lol haven't tested it out yet though.
The beauty about the T3 reticle is that it can be used on any cartridge as long as the wind dots have been calibrated correctly. Let us know how you like it once you've had a chance to use it!
@@HorusVision I think in reality each dot is closer to 4 mph cross wind with my gun and load. although usually I just shoot a target at 100 yards (a 2 mil hold with a 50 yard zero for 22lr) to figure out which dot to use then stretch out from there. I've successfully used it to get first round hits at 200 (about 6 mil) and 300 (13 mil, have to hold in space since the wind dots stop at 10 mil but I just imagine line continuing out to there) yards in 15 -20 mph wind pretty frequently which is kinda crazy for a 22. I'm now a firm believer in it and it definitely helps out.
@@aharkey1077 You can check out of new FREE app too, it has an automatic wind dot calibration tool!
Well....I just listened to 6 1/2 minutes of lecture. I'm 6 1/2 minutes older and still don't know how to use it.
Hello,
There is a learning curve when it comes to operating a Horus reticle. Once you begin to understand the functions of our reticles they are quite user-friendly. If you would like to give us a call we can assist you in learning the functions of the Tremor3 reticle. (866) 568-2926. Have a good day.
Get applied ballistics app. Enter your rifles data and put in 29.92 station pressure and 59°
Scroll through yardage until your elevation is equal to 4.0 mils now add 1 mph of wind at a time until your wind call is at .95 mils. Whatever said wind speed is equal to .95 mils, take it and divide by 2 and you have the value of your wind dots at most any distance WITHOUT SPIN DRIFT ENABLED
@@pumpsprecision3520 THANK YOU. I think Mr. Hodnett forgot how far above us he is here. Now that I have what you said, what he said makes much more sense.
Again, thank you!
@@wilfdarr no problem brother. I work for AB and have to simplify things down for our courses pretty regular. A few repetitions in the field with this and it will be like riding a bike!
@@pumpsprecision3520 Since you work for AB, maybe you could email Horus and get your 'for dummies' version applied (😉) to the description?

Hello,
Thank you for your feedback. We are working hard on this and hope to have something very soon that will start to cover items like you have mentioned. The hard part has been putting quality information in a format that makes sense to everyone. Again, thank you for your time!
Spot on. I'm in the market for a new scope, and I am a new shooter and trying to learn more about this reticle for my first long range rifle. I'm reading everything I can and studying my options, but a simple 'from the ground up' video on how to use this would greatly influence my reticle decision.
Just think of it as a huge 2 dimensional ruler in your scope. Reduces the need to dial for long range shots and allows for easy corrections. It's seems wierd on paper. After you shoot it it will make so much more sense.
@rascalMatt17 the ACSS is a ballistic reticle that is only good for certain rounds travelling a certain speed out to a certain distance, it's basically a "best guess". It's great for the regular shooter, not precision shooting. If you can understand how "old school" sniping works with dialing for elevation and wind, the hourus reticle just simplifies that, and can work for ANY caliber.
So if I sight in a 308 dead on at 300 yards with 175 gr SMK, rather than dead on at 100 yards, will the wind dot’s still work?
It seems that since would less holdover at say 600 yards, the wind dots would be worth more than 4 mph.
