How to use a Brunton Pocket Transit

[@DougMacRay]

It you're watching this and you are a first time user of a transit, there's an important ERROR at 4:50. The lecturer reverses the description of the two compass "roses." He uses the Azimuthal diagram to describe a Quadrant Compass. Additionally, his elaboration on why a quadrant compass is better should only be interpreted as subjective because the azimuthal compass is superior to the quadrant if deployed for land-nav purposes. Seriously though, congratulations to the lecturer because even after a half decade, this is one of a very, very few videos on the internet which identifies how to use the Brunton Transit and all it's applications. I was just given a Brunton Transit and with no one to teach me how to use it, I'm self taught as to how to make the damn thing "work." He did a good job evaluating this unique, complex tool and this material has stood up to the test of time. Thank you. Respectfully, Boston

The headings over the two "roses" was also backwards. ie Azimuthal over the quadrantal rose and vice versa. A bit sloppy for a university level demonstration.....

[@kenwebster5053]

@@terrygoyan It's obviously a page topic heading across the whole page. Not separate image headings. So it's a pedantic point but I agree clearer teaching practice to retain the order of mention.

Thank you ...just brought out my compass from 20 years ago and need to mark off a lot line in remote Alaska...i remember now!

Hats off to the lecturer! He has explained in a very lucid and smooth manner covering all the aspects of the Brunton. This video was suggested to me by a senior geophysicist at Geological Survey of India! One of the very few videos on the internet explaining the Brunton completely. Thank You, Sir! Regards An Indian

Great compasses, mine is in mils, which was not mentioned. Much training and practice needed, thank you for your valuable input!

I'm glad you made this. I just picked one of these up in the box with the book and all the original packaging for next to nothing. I don't really need a 400 dollar compass but I couldn't really justify not getting it beings I paid the same price for it as my silva ranger. But this video is a lot nicer being able to visually see someone rather than just relying on reading the manual is cool. Thanks.

despite the various errors in the presentation, I managed to learn some things. Thanks!

If I’m frequently looking at my notes, have I thoroughly prepared the lecture?

[@LLuE88]

WOULD YOU PLEASE PUBLISH A DESCRIPTION LIST OF THE CONFUSING INFORMATION, ie "QUADRANT" COMPASS MEASUREMENT GOES FROM "0" TO "360" - HOWEVER ON A "QUADRANT" COMPASS YOU HAVE FOUR SECTIONS THAT GO FROM "0" TO "90" DEGREES, ETC:

[@kenwebster5053]

Well, I have an old brass Brunton transit. The clinometer bearing is offset to one side of the compass bearing. On the underside, there is a short length of a pin protruding from the exact centre of the body. At least, it may be a separate part and not just an machining anomaly, hard to tell. This would be exactly in line with the compass bearing. This pin prevents the clinometer from rotating through it's full scale. I only get from about 55 degrees movement with the clinometer scale. Not sure what the pin is or what to do about it. Maybe it's the end of the compass compass pivot pin, slipped out of place? Advice please?

[@robertcolpitts4534]

You have a cheap replica of a Brunton Pocket Transit; the true Brunton is constructed of aluminum. Put it on the shelf and buy a real one. Then, you will have the full clinometer arc.

Don't use a screwdriver either with a magnetic tip or that might have become slightly magnetized. Yes, it happen to me luckily I caught it.

[@rudradevgvastu]

advice me the suitable compass as i am the residing in India and the declination is about 2 degrees west of true north

[@TyJee28]

In your triangulation example. Why do you teach to draw the line from the sighted object toward your estimated position with the back azimuth ? For example, the hill top to the northwest was measured as N45˚W, but the instruction was to draw the line from the hilltop toward the estimated position - that is draw a line from the hilltop toward S45˚E. It seems to me that the line drawn, connecting the hilltop and estimated position, would be the same horizontal angle whether it is drawn as N45˚W or S45˚E. Land navigation text usually calls this resection. Most also teach to draw the line from the sighted object with the back azimuth, but not all do. But no one ever explains why they teach to use the back azimuth. On a 360˚ compass we would say the hilltop was at 315˚ and the line should be drawn from the hilltop at 135˚. But a line drawn from my assumed position to the the hilltop at 315˚ puts the line on the map in exactly on top of the other line. So why use a back azimuth for triangulation / resection ?

[@brianblackmore1678]

The sighted object has a known position on the map, whereas your assumed position does not. Navigation lines are drawn from known positions. Your triangulated position is where lines cross, which likely won't match your assumed position.

how can i adjust magnetic declination on konustar compass

[@westonmulenga6421]

welll done,i hav got the concept thanks

[@xusmico187]

error: instructor looking at manual to tell him what the parts are.

[@LLuE88]

?? MY WHITE NEEDLE END POINTS TO THE NORTH ?? JUST DOUBLE CHECKED IT.

[@shannono.5835]

Me too… he said white is magnetic south seeking and then he called it the North Pole… ???

Geologists only think and talk about periods of millions of years. They have different methods for determining the age of rock layers. However, there is one small problem. Ancient books tell us that a cycle of natural disasters threatens the earth and all living things. The cause of this cycle of disasters is a ninth planet in our solar system orbiting the sun in an eccentric orbit. Features of the natural disaster include a massive tidal wave, higher than the highest mountain, flooding, storms, rain, volcanic eruptions, earthquakes, and a fiery asteroid bombardment. That planet is surrounded by a gigantic twisting cloud of dust and meteorites. That cloud obscures the atmosphere, pollutes the water and covers the whole planet Earth with that dust. At the end of the crossing of this planet 9, the earth is covered with a horizontal layer of wet mud, a mixture of sand, clay, lime, fossils of sea and land animals, shells and the deposit of that dust cloud and asteroids. So every layer on our planet contains material with the same antiquity, perhaps many millions of years old: the deposit of extraterrestrial clay and meteorites. So the youngest, topmost layer, which is less than 6,000 years old, also contains these very old materials. If you don't know about this cycle, you have no idea how our history has evolved. To learn much more about planet 9, the recurring flood cycle and its timeline, the re-creation of civilizations and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9

Very shaky camera work.

he's no lecturer... I gave up...
