Thank you Dave. Very clean and simply explanation. Back in the early 70's this was a skill I learned and the Boy Scouts and have forgotten. Also in the Sea Explores I learned navigation by use of a sexton, which you don't even find on a boat today. We have become to depended on technology. We need more people like you reminding us of the pass technologies that didn't depend on satellites and batteries. I will not make on out of plastic and keep it in my pack. Hope you add this skill to your classes. Keep up the great work!!!

[@bobman620]

Great Video. Glad you keep revisiting this topic. Here's tip on using the inclinometer on the shadowboard. Instead of lining the top edge of the board up to the sun and then using the line to read the angle, try this: Use the line to keep the board straight and plumb with the board edge on to the sun - then the shadow cast by the center pin will show you the sun's angle. This way you don't have to look into the sun and it is easier to hold everything steady.

[@aktrapper6126]

Very well done and explained. I really like the way you validate the whole process with a compass at home while becoming familiar with this system. By doing this you will have confidence in it in a real life situation when you don't have the compass. Thanks for sharing Mr. Dave.

[@hameggs4837]

Thanks. That was totally awesome. Kinda gives us an insight to the way things got done before modern manufacturing. I am fascinated with the way land was surveyed back in the 1730s when they used to use chains and other primitive methods for measuring.

[@naturedownsouth]

This method is very simple and very effective. Thanks Dave! No matter where you are in the world you can find your way out.

[@nikitia82]

Bandana would work even in a pinch with the marks with the sail needle, this was another great life lesson, everytime i turn on the news another women lost lately. I have been their myself lol Not anymore, Iam learning not sure if i got the night shawdow down with the moon, but this hands with sun makes so much sense Thank you!!

[@blackhatbushcraft]

It was very interesting to see how accurate the inclinometer was to get your angle. I really like that addition. That would make this system that much better when in hill country or in the woods where you may not be able to see the horizon very well. Thank you for sharing this.

[@charlesloveday9208]

Awesome Dave! Best directional advice I've seen outside a compass.

[@deepblueyonderspage]

Devices for measuring angle or slope are called Clinometers...Yep I know they are also referred to as inclinometers, just placing my forestry bias on it. lol Excellent job with the shadow board! I can see how a tool like this could be easily put together on the fly in the field.. knowledge is definitely power! Thanks Dave!

[@BLACKIETHOMAS]

i think your really on to something here dave..thanks for posting..safe journeys

[@johnboleyjr.1698]

I love the board, with the inclinometer. Almost like a compass, and a sextant had a baby. :)

[@SamuelTyree1]

Sailors use to use a back staff. This was a device the held over their shoulder with their back to the sun so they didn't blind themselves. A couple of nails, pegs, eye screws, soda straw, etc. located on the top edge of the board and some sort of flat surface for the shadows to fall on. If two eye screws were used, you could stand with your back to the sun, align the shadows on the flat surface and then take your reading as you did in the video. Less eye strain and discomfort.

[@mlugin8050]

Very interesting as always. I'm thankful for all the knowledge and the enthusiasm you share!

[@tylerglidden2922]

I'm a land surveyor and I have to say I didn't know that and I found it very interesting.

[@alexwbanks70]

You are a great instructor Dave. I will take some of your classes when I have the funds.

[@RedDogBushCraft]

The Mariners Museum in Newport News had a demonstration with a similar shadow board. Pretty cool.

[@Jmoom12]

thanks Dave. Gonna make one of those now to practice with.

[@50StichesSteel]

I use something similar on my "Milldot Master" to measure incline and decline for shooting long range...Good stuff

[@sane9875]

WOW!! Great video Dave!

[@ACDCRD]

Hey Dave love your videos!

[@timothygraham4304]

Thanks for this video. I will definitely trying this out at the weekend now that the weather is warming up here in Ireland. Great info :)

[@darrinmartin8247]

Dave is the king !

[@threeredstars]

Pretty cool Dave. Thanks Brother!!!

[@KillingerUSA]

Good stuff Dave!

[@Clanmaki]

Great teaching Dave!

[@Donnybrook10]

great vid. Im gonna make one of those boards. Thanks Dave

[@singleman1986]

Excellent lesson. Thank you!

[@Comeandtakeit1]

Your channel is rollin brother, congratulations!

[@LShapedAmbush]

Great stuff! Thanks, Dave.

[@Nate-jg6ur]

You should do a Q&A some time. Love the show man

[@maisetas]

priceless lesson. btw, dave , i have watched Lost survivors s01e05 and the host shows how vikings back then navigated by a sun even when the sky was overcast. they used something like ice crystal to find the sun. would be nice if you could cover that up in more detail in future videos.

[@wyatt9345]

Dave, in an unrelated request, I'd like know if you would do a short review of the new Schrade froe. As a homesteader and bushcrafter I would simply like to hear your thought on this wood processing tool.

[@Jonboyr700]

Love it! So ingenious.

[@tripplewhipper]

awesome tricks, thanks for sharing!

[@daved4753]

So in the northern hemisphere, make the adjustment away from the sun, in the Southern Hemisphere make the adjustment towards the sun? Should work the same way whether it's afternoon or morning.

[@darylsarbaugh3491]

What do you suggest at noon? I realize that afternoon it will be in reverse using height to the west and shadow along east side and turning board right to line up west. 90 degrees the shadow should point north right?

[@SuperJhon360]

when your mesureing the sun is your hand sideways or upright and if your hand is mesured sideways do you include the thumb in the mesurement or do you just use the width of your palm

[@jamesparlane9289]

An astrolabe is also an inclinometer . You can also use it o work out the height of things like trees using the tan key on your calculator.

[@carlostavares6052]

Great job. Thank you very much. Well done.

[@GyokkoRyuKosshijutsu]

So if it is cloudy, we would use the Sunstone to find the sun, then line up the board with where the shadow SHOULD be?

[@JeffMeadowsOutdoors]

Does the inclinometer work around noon? In the winter the sun is not at 90 degrees even when it is due south. Other than that it seems to work great.

[@josephkellam6710]

does the seasons change the angles when the sun is lower in the South in winter

[@Waterboy2000]

Interesting! Are you pointing the inclinometer at bottom, center, or top of sun? Sounded like top when you said so it wouldn't blind you. Does it matter?

[@BB_46]

Thanks Dave, is it always around 15 degree per hour durning different times of the year, Shorter days vs longer days or does length of the day matter?

[@quinbus51]

I'm wondering what happens at different times of the year... On December 21st, the sun rises at its most southeasterly point on the horizon. On June 21st it rises almost dead east. How do you adjust for those seasonal differences using your method?

[@feellnfroggy]

Is this something you could draw on the bottom of your bushpot?

[@Pascal-asia]

thats good to know,i learned something ,thx for sharing

[@victorwaddell6530]

Install a clinometer into the stock of your survival shotgun / muzzle loader ! It would be more accurate , and you could use it to look down the barrel and get the angle of Polaris , the North Star , to estimate your North Lattitude .

[@NewbTactical]

damn dave your good GREAT stuff man

[@yaroslavbozhkov1567]

Thank you brother! It works.

[@banjobushcraft8454]

Need that shadow board printed on a t-shirt!

[@dannyh9010]

I was thinking blaze orange or an Olive drab bandana, with some instructions, too. I'd buy that!

[@SarasotaTim]

I am a subscriber and I thought this video was interesting but I miss the hammock camping knot tying and bush crafting type videos

[@ladyofthemasque]

Declination varies depending upon location. If you are in Portland, Maine or Portland, Oregon, it's going to be different than if you're in St. Louis, Missouri. Up here near Seattle, it's about 15 degrees declination at the moment (it's even higher the closer you get to the Canadian border). There are online resources for checking your declination, so click on the link below so you can Know Before You Go! Here's the link to a place that will give you your latitude & longitude (based on zip code) in the right-hand box (in case you don't know that, as many people do not), and your declination based on the lat. and long. in the left-hand box: www.ngdc.noaa.gov/geomag-web/

[@michaelcarter8209]

Awesome

[@samcronk4555]

Just curious but is this similar to a sextant or am I completely off base?

[@dutchcourage7312]

Nopes, it basically is, well, if you include some knowledge and math... the angle you would measure from the sun at midday is an indication of your latitude (given you correct for the time of year), which is what the sextant is generally used for... and given you have the charts to go along with the sextant all you really need is a way to measure the need to know angle, which a simple inclinometer is capable off ... And if you have a very accurate watch and know how to use the sun to determine midday, you can even calculate your longitude, as it would be the difference in time between your local midday (that you measure from the sun) and the midday on your watch.

[@samcronk4555]

Thank you!

[@abefrohman1759]

Your a woodsman Mr Wizard Dave.

[@James_Bowie]

Good stuff! (I think you mean to say clinometer).

[@johnlord8337]

10* Easily explaining a very difficult topic.

[@1Selous]

simler to a Sun Dial Used by SAS back in WW2

[@dank.6739]

I wonder what kind of birds are singing in the background.

[@dannyh9010]

It's amazing how you tune them out the first time through the video! This is in SE Ohio. I'm from Ohio, too and know some bird calls, and I attended one of Dave's basic classes last year. It's a very nice property with lots of birds. In the video, I heard house sparrows, grackles, crow (1:57), blue jay (0:20, 3:00), house finches, purple finches, red-winged blackbirds (0:09 and often after, 5:52 is a god one) , red-bellied woodpecker (0:04, and often after), cardinal (4:28, but tough to hear, 8:04, but covered up soon after by a loud red-bellied) and saw turkey vulture circling (not calling) at 6:56. There are mockingbirds at Dave's property, too. They do all sorts of bird and other weird calls and sounds, too. Thanks for the fun exercise!

[@dank.6739]

The only one I know was the Red Winged Blackbird and crow, we do not have the others here in WA)

[@dannyh9010]

Sounds like a trip to Dave's Basic class is in order for you. You know, to study the birds.

[@dank.6739]

Just let me flap my wings lol

[@BorealWoodsrunner]

It's kinda complicated...but it's really not. Dave Canterbury
