Two Sighting Compasses

- I take a look at two Chinese made sighting compasses.
I bought these off of Ebay and they have no model numbers of manufactures names.
The larger one is all metal construction and it heavy 10.2oz
The smaller one has some plastic and is half the weight at 5.9 oz.

The compasses are copies of a famous german compass of the 1930ies. It was the Wilhelm Kienzler (WilKie) MERIDIAN and was at that time the first one with a thermoelastic capsule to prevent bubbles between -30°C and 70°C.
The fluid formula is still secret up today and the original compasses are now manufactured by K&F Germany.
These chinese copies are not bad but materials and production quality is higher at the originals.
Great information, thanks. I'm going to pin your comment.
I just received this compass today, and I have to say it is much nicer than I expected. What I most like about it was the rear sight notch and the cross hairs on the plastic disk, and the aperture with a magnifying lens so that you can read the azimuth without moving. Seems to be very will made - great features.
I will buy the some compass thanks for the review 😊
Can you please do a video on how to use these compasses?
I'll have to put one together, though I can't say when.
Did you see where you could adjust for magnetic north? The instructions that came with mine were all in Chinese.
I now have four sighting compasses, all similar but non have a declination adjustment.
Yes, we can see it's "nice" and "stuff" but how does it actually work? Your generalizations are not working.
Hmm, they do work but I get your point. Since i made this video I've gotten another of this style compass.
I'll try and remake this video and add some field tests.
America was measured by a Gunter's chain 66 foot but with a work crew that all worked as one. I have often wondered how many surveyors would stay in business if for some reason there were no more batteries for their total stations and that could happen with all the shortages that are going on these days. Now about the compass it is great and that is my pick for rough places above all the others.
Modern stuff is definitely more accurate and nicer. Better than dragging chain thru blackberry thickets and poison oak like in the old days. 😊
I was thinking about getting one does it really truly Point north
All of mine do.
Yes but no declination for map reading.
What's the difference between lensatic and Prismatic Compass
Lensatic compass is the style used by the US Army where you get your compass reading by looking through the lens on the arm positioned over the compass bezel. A prismatic Compass the reading is found by looking through the sighting hole, prism.
The two compasses in this video are prismatic compasses.
Have you tried using them outdoors yet to see how you like these types of compass?
No, Ive played with them a little bit but they are just part of my collection,.
why does my inclinometer keep falling off, like i fix it back in the place, but it falls off immediately
I can't say, mine is solidly attached. You may have lose or missing attachment screws or pins.
You might try a little "lock tight blue" on the screws and pins.
Good luck.
@@planetsideagent thank u! i glued the screw and now it doesn’t fall off anymore haha
My friend and I are in the woods, both of us have compasses, neither of us have GPS, we have walkie talkies and I can ask my friend for the heading from his compass. Is there a way for me to know if I'm walking towards him?
Lol hope you are not searching for him still
@@dontexpectreply I figured it out using Bluetooth ble and a compass. BLE tells you how far another ble device is from you. By sharing the compass reading between the ble devices, i use triangulation to figure out the heading towards each other. I'm publishing the code in the reflections project on GitHub
Personally, if I am navigating in the woods I wouldn't mind having it. I bought some Molle grenade pouches off eBay and those compasses fit in them like a glove. I have molle all over my ruck and belt so no issue there. Better a "heavy" compass than no compass as the Vikings said before crashing into Newfoundland.
🙂
I'm New to Navigation, I have recently bought one of these compasses. I was wondering what the markings on the sighting window are used for? I have searched for days & can't find anywhere that even comes close to mentioning the marking on the window except for the obvious center line.
I too was curious about those lines and was able to find out they're use. That said, I have promptly forgotten what they are for and where I found the info.
I'll try and find the info again and get back to you. It may take a bit since I'm still wrapped up in summer chores.
I found the instructions for those lines in the manual that came with the compass, they are minimal at best.
Basically they are used for measuring distance.
I too couldn't find anything on the web on what they are much less on how to use them. I need to go out and see if i can figure it out, I'll make video it I succeed.
Do you have an email address, I'll send you a photo from the manual.
@@planetsideagent Thank you so much for taking the time to explore this for me (See what I did there? Explore/Compass). My e-mail: {Deleted after your reply}
I am in a wheelchair btw & right before COVID hit the World, I bought a £7k All-terrain Wheelchair so I can go on these bushcrafting/camping holidays but as I am in the AT RISK category I am stuck firmly indoors.
Thanks again for all your help.

@@planetsideagent Those lines allow you to measure the angle between two objects (or any two points). They are probably in degrees (since the rest of the compass is marked in degrees and there are no mils markings anywhere).
Once you have the angle between two objects/points you can estimate the distance to the objects if you know the distance between them, using trigonometry.
Though, for these estimations what is usually done is that you take a rough equivalent from a table rather than performing the full trig calculation.
You may know some of that theory already as the "1 in 60" rule. At 1° an object is approximately 60 times further away than it is wide.
Imagine that you measure the angle between the front and rear of a parked car and find that it's 1°. Assuming the length of the car to be, say, 15 feet... You are approximately 15' x 60 = 900' away.
(It's actually 57.29 times further so you'd be nearer 860'... but this is only an approximation).
Alternatively you could pick two identifiable marks on the horizon and then measure the angle between them. Then find them on your map and measure the distance between them. Then perform the calculation on those figures.
Great, thanks for the info.
Thx 😉✌️ ... are they working korrekt ?
Yes.
🍀🍀🍀✌️😉✌️🍀🍀🍀thx ...
@Michael Freestone мой английский приемлемый. Как твой русский?
@Michael Freestone actually it’s Russian a language spoken before Communism, which is a political and economic system, came to be. Russia is no longer a communist country, that ended with the fall of the Soviet Union.
Besides English, what other languages do you speak?
@Michael Freestone fair enough. Have a good one.
Are these as accurate as a usgi compass?
Sorry that I don't know.
I thought about it a bit more and yes I think it will work as well. If you get the model with the inclination gauge you would have an added feature the usgi doesn't
Yes and No, the main issue is the quality control. A USGI is mil-spec. Those are "china quality spec"... So you can get a really good compass or pure junk.
A second problem is the calibration of the compass. You need a compass that work in your magnetic zone. The world is classically divided in 5 zones. China is zone 2. North America, Europe and Russia is zone 1. If you use a zone 2 in a zone 1, your compass can run into some problem. If you use a zone 2 in a zone 5. You will have a lot of problem with it. Now tell me how your compass is calibrated?
Modern quality compass usually reduce the number of zones between 3 or 2. You can even buy global needles compass. But the price difference between an MC-2 Northern hemisphere and an MC-2 global is the price of most Chinese compass alone!
Parabéns Ótimo videu 👍👍🇧🇷
Heavyest compass ever, not worth using in the outdoors trekking world it's way too much to add to your kitbag! And not any more usefull than a silva
True they are beasts. I carry a Silva Forester in the field.
hole europe uses metric ........ is more precise
yep, I don't know what economic interest vetoed our conversion. its stupid but that's the way we are sometimes.
All air and maritime navigation is based on nautical miles anyway. One degree north or south equals 60 nautical miles. Metric is just another invention. Neither is "more precise."
@@stevek8829 measuring distances with nautical miles does not mean the metric sistem is " not more precise", the sistem you mentioned is acurate but not so precise , please make a difrence , the more "resolution" a measuring sistem has the more precise AND acurate is ... like pixels on a monitor .. the smaller they are the better quality of image ... so is with the metric units ... the smaller the subdivision is , so the sistem gets more acurate and precise
@@stevek8829 Imperial units are defined in metric.
But definition, metric is more precise.
@@Hebdomad7 considering metric is far newer, your logic is amusingly stupid.
Wrong as usual A the first compass is perfect for back packing biking and camping B you stated you received a package without knowing what it was!!?? You sounded like a porch pirate 😊
Porch pirate on my own porch, I get a lot of packages and I'm never sure what is coming in. 🙂
