Slope angle with or without a clinometer

[@stpetie7686]

This guy posts the best orienteering videos I've ever seen. Simple, clean, explanations that actually make sense. Thanks a lot, MRC.

[@TheMapReadingCompany]

Wow, thanks!

[@CptnKremmen]

I have an old, pre-GPS, Suunto ski watch in drawer somewhere that would use its clinometer to calculate speed down the slope based on vertical descent measured by its barometer. Thanks for taking the time to make an interesting and informative channel.

[@TheMapReadingCompany]

Thanks for sharing!

[@rainbow2710]

Really enjoy your easy to understand presentations.

[@TheMangeGrain]

So simple ! Actually as a hiker I don't have much need for precise slope angles and none of my compasses has any clinometer. But I'm happy to learn that all my compasses can actually at least approximate slope angles so easily. I guess this unexpected feature will be more useful during DYI projects than during my hikes, though. Thanks for the clear explanation.

Hello, New to your channel as of now. This is the first video I find on how to use the north south lines and the bezel to find slope angle without a clinometer (a feature that comes with a fortune added to the cost). Very informative and well explained. Much appreciated.

[@ervano798]

All my compasses have a clinometer, but i never used them. Your trick came never in my mind to do it that way. A very good tip in case if i need it once. (probably never) Only one time i used the clinometer when we build a friends gardenshed for measuring the angle for the roof of the shed.

[@stecoach3125]

Another excellent video presentation. Looking forward to your next one.

[@TheMapReadingCompany]

Thanks for the feedback Ste

@@TheMapReadingCompany Thank you for these videos! I do have a question/comment though: At around 3:30 in the video you explain the non-clinometer/-inclinometer compass usage. Why not set the compass to “due north” and get the inclination angle directly instead of having to recalculate the angle difference? Just curious.

[@TheMapReadingCompany]

Good question. The idea of using East (90) is that it enables the orienting arrow to be used as the vertical pointer. If you set the compass to North there is nothing to use as the vertical. Hope this helps

[@AntonyFade]

Amazing, thank you !

[@freezerburn04]

That was great, thank you Sir

[@TheMapReadingCompany]

Glad you enjoyed it

[@Robert32571]

Ok, I UNDERSTOOD NOW !

[@GiC7]

Thanks

A question about method using the hole on the mirror compass: when you say to point at the "target", do you mean the top of the slope?

[@TheMapReadingCompany]

Yes that's right. Look through the hole at what you want to get the angle to. This could be the top of a hill or something else.

[@Rozenix]

How to measure the angle of inclination using a compass with a mirror, without a clinometer? The compass has a hole in the bottom of the mirror, but if you aim at a point and set the mirror at a 45-degree angle, it is difficult to rotate the compass dial.

[@GiovanniPalumbo-v5c]

Is any way to do the same with a lensatic compass (i.e. Cammenga)?

[@TheMapReadingCompany]

Not that I know of, as they don't have orienting lines. Maybe someone who is more proficient with Lensatic compasses may have a way of doing this.

[@GiovanniPalumbo-v5c]

Thanks for the prompt answer and congrats for the videos posted. They are very clear and useful !

[@leftfootforward1040]

I use the eyeballnomiter 😉

[@Senseigainz]

Do you rest it on its edge on the floor? How will pointing it be correct?

[@TheMapReadingCompany]

Using a compass to take the angle of a slope is only ever to give you an approximate average. It’s never going to be exact as hills and mountains don’t have regular smooth shapes. When taking the angle of a slope it’s not a good idea to rest the compass on the floor as this is it will only give you the angle of the few inches that the compass is resting on. Most people will want to know the average angle of a slope (or a section of the slope) they are going to walk up or down. To do this you need hold the compass so that it’s at the same angle as the hill or mountain side (basically you point it) this is when the angle can be read from the dial.

[@Senseigainz]

@@TheMapReadingCompany so if I look down the compass edge and point to the peak of the hill, that should give me a rough estimate?

[@TheMapReadingCompany]

Yes but from the bottom to the top of a hill it will only be a very rough estimate.

[@Robert32571]

Please, can we measure the height of a tree with a clinometer? If so, how do we translate degrees into distance? thank you for your availability

[@jwnomad]

measure your distance to tree (eg. convert paces to m), measure angle to top of tree in degrees, height of tree = tan(angle)*distance.

[@mihailvormittag6211]

👍

[@jwnomad]

Or you can measure it on your topographical map and calculate tan^-1(rise/run).

[@MiroslavJoler]

It was kind of unclear and insufficient in the segment of mirror compasses, but the last part with simple compasses did it well.

[@nafnist]

In surveying (in my country) we call it inclinometer. It is like flammable and inflammable, i guess.

[@TheMapReadingCompany]

In English flammable means something will burn (like petrol) and inflammable mean it will ignite and then burn (like diesel)

[@Wild-Camping]

I assume this only works from the very base looking up or top looking down, what I mean is, if you took a reading 20 meters before you got to the base of a hill, then you took another at the very base, surely you would get different numbers/angles.🤔

[@TheMapReadingCompany]

The angle messured is of the compass itself. So if you point it up a slope you would get the angle of that slope. If you pointed the edge of the compass from some distance away to the top of a hill you would get the angle to the top from your current location. Hope this helps
