If I ever meet you I am going hold you down and wet willy your ear for exactly 8 mins. 22 seconds because thats how long you wasted on NOTHING in this vid.
@TheZoltanF I wish. I also have two rather bad scars, one from a mole on my back, one directly opposite on my shoulder from a tumor removal. It handily is right past the edge of body armor, so would be easy to attribute to a fragment or other projectile. But it's all much more boring.
@timjseg What needs cleaning? Mostly, hose it off if needed.
Sometimes they can get gummed up. Turns out, it's easy to get them apart without destroying them. Unscrew the four screws on the bottom of the case and pull of the plate. You'll find the entire capsule (the compass part) is actually a capsule. A rubber-covered little cylinder. Pull it out (carefully, to not tear the rubber, but it's gonna take some force) then you can clean the hinge and needle-lock mechanisms, and so on. More...
Continues... Be sure to put some white lithium grease on the capsule sides before re-inserting, so it goes in easy and comes out if you need to pull it apart again.
@onehitkill That is a good point. Remind me in a month or so to make a video. REALLY busy now finishing off my book. In brief: find a 200 space. Measure it. Walk it, counting every left footfall, as naturally as possible. Divide by 2, write it down. Do this several times, even on different days, so you are sure you are getting a good result. Now you know how many steps per 100 m, and you can use counting beads, to track distance traveled.
@zealberg Naw, it was just synching email or something. That's indeed mobile network noise, but all in the radio band. I didn't hear it until after the recording. Sorry for that :( I put my phone far away in later videos.
@zealberg Use math! First, you need to figure out how many mils yours has. If modern, NATO standard, it's gonna be 6400. But if not, could be anything. Then 360/6400 tells you 1 degree is 17.78 (ish) mils. So 5° is almost 89 mils. So, a hair to the left of the 9 (or maybe 90) tick on your compass.
@zealberg didn't think newer phones did that anymore. Mine always used to do it. but hasnt for a few years now. maybe because i changed phone services?
Hey,i have black tactical marching compass,and,if you know,how can i use it? Its like USGI,but with small differences.Sorry for asking for new tutorial,but there are no other tutorials on internet...
@4MePlox I don't have one of these, so can't make a video. Oh, also, I lost the Elmo when I changed jobs so can't make any of these right now :(
When teaching in person, I usually just make everyone who comes with foreign compasses, and so on (as long as they aren't so stupid as to be dangerous) to show them off, and point out what the differences are so they can follow along. I can't do that since I am not there, but if you follow along carefully...
@shoobe01 Yes,thanks for telling me :) I already know something little about it but i think that is the common thing compasses are made for...Thanks anyway :)
i have a basic understanding of navigation, but want to understand it more. Most of my use of a compass will be on topo maps for camping/hiking/hunting. I like clear base compasses for ease of use on a topo map. How would this style compare in ease of use vs. clear base styles?
@Diopterman Um... too much to type here. Might be worth skimming these videos, then my baseplate video so you see how I compare them. Yeah, it'll take a while, but then you get to see how stuff works.
I also prefer the baseplate, and note that the UK, Canada, a lot of other armies in the world, and many individual soldiers in the US buy and carry baseplate or ranger (mirror) compasses. They work.
Oh: One thing the USGI is good for is night work. If not what you do, you will not care.
I got this compass today.After putting the compass on the table, I realised that the disc inside is not horizontal... The North arrow is pointing upward. Is this normal for this compass?
@csar3 Yup, as long as it doesn't drag on the inside of the capsule, that's correct. It's because the magnetic field is not parallel to the surface of the earth, but sorta points straight at the poles. This is a "world compass" (not regional) because it has enough room for the magnetic disk to tilt, and the bearings work like that, etc.
Of course, make sure the table doesn't have metal legs, etc. Use it outside, away from metal things.
Tritium radiation only produces beta rays. They can't even go past your skin.... First mm of your body skin would stop beta radiation from the T in this compass.
@mashersixone Oh, I always forget the CYA notes. Yes, if you work in a company or for an agency, you damned well better follow the rules. It's radioactive enough (and a bomb component) so the NRC cares A LOT what happens to it.
Lost a job? I presume a contractor, not a DoD employee???
@shoobe01 NCO or not..theres a lot of people high up who dont share the truth or just dont know. Remember Agent Orange was harmless...im sure your right. Its hard to know what harmless for us these days. Cell phones and brain cancer..who knew?
@shoobe01 True it is complex, thats why there is controversy regarding it. Im sure your aware of Australias findings on this matter, how bout them cell phone towers? Not exactly producing oxygen an evergreen does do they. Hey do you know if using a watch to find North is affected by Daylight savings 1 hr difference?
@CherokeeTwilight Several watch methods. This covers them all wikihow . com /Find-True-North-Without-a-Compass Yes, the one where you line up at noon has to be done at 1 if on savings time. Note that page also covers southern-hemisphere variations well, which many do not.
question...i have friends that were in the military that told me they were warned about repeated use on I Gen, II Gen, III Gen night vision because of radiation exposure. What about the tritium compass since it has a radiation symbol and it hangs around the neck? Nice video :) I do feel more confident about using a compass after your tutorial.:)
@CherokeeTwilight um... for night vision, that's just stupid NCOs spreading ignorance. NODs have NO radiological component. The official US Mil guidance is on extended use for eyestrain, as it reduces your ability to do your job well; e.g. helicopter pilots have to trade off every so often.
Tritium is fairly un-radioactive, and it's insanely tiny amounts. Someone who works with this did the math a few years back, and calculated (as I recall) you'd have to break 10,000 front sight vials...
... at once, and breathe in ALL of the gas at once to get one x-ray's worth of radiation. Especially sealed in a big metal box, a compass is super-safe.
To save money I intend to buy the phosphorescent version Cammenga. I wanted to ask you if you think the phosphorescent compass would be sufficient for unlikely night time use, such as getting lost and trying to backtrack after dark (I always have a headlamp in my hiking kit). Also, I am completely ignorant about compass navigation and wish to educate myself to a novice, will this compass be suitable as a learning tool? I appreciate any thoughts on this matter.
@cockercane You can probably get a tritium USGI one cheaper than a new phosphorescent one, but the army also issues the non-tritium model, and they are sometimes available for like $10. Don't pay too much.
Tritium is mostly valuable because you don't need to shine a light at it to light it up. If you need to be tactical, this is crucial. But otherwise, not so much. I would make sure you have spare lights, and spare batteries though...
I also suggest a small UV light (like a keychain sized one). Phosphorescent materials absorb energy NOT in white light but in UV. So, shining UV gets them charged faster, and the light purple (it's hard to find pure UV) doesn't kill your night vision like a bright white light will.
Just a random question about the Tritium lights on the compass shown in this video, do they still illuminate? I'm curious cause they say the half life of tritium is 10 years, and from watching this video I noticed 92 03 XX numbers, I could be wrong but that is a 18 year old compass made in 1992. BTW, quality 8 part video series.
@10karhu Not that random. And you read the date right. I skipped it in the video, but in class I try to make people think back to physics. Half life is not LIFE, but half-life. After (appx) 10 years, half the radioactivity from tritium is emitted as the day it was made. After 20 years, half of that, etc. into infinity. So, it gets logarithmically dimmer, but takes a very long time before it's so dark you cannot see it.
Additionally, I'm very much of the opinion that the new ones are SO bright you cannot use them. The bright parts drown out the dimmer parts (its hard to read numbers through the glare) And either way, your night vision is gonna be messed up. So I prefer these older compasses actually.
Shoobe. what's the 0-300 ruler like thing i see in the army map reading and land navigation book? I'm kinda thinking, u coverd that with the protractor or the other vid with finding exact location. not sure if thats right, sorry I'm new at this and still somewhat confused. thanks
@trooper2221 Not following "0-300 ruler like thing." Describe a bit more or give me the FM # so I know which one for sure, and a section title (mine may be a different date, so page numbers are no good).

i need to compensate for 5 degrees west declination in my area (ireland)
thanks again

@zealberg Use math! First, you need to figure out how many mils yours has. If modern, NATO standard, it's gonna be 6400. But if not, could be anything. Then 360/6400 tells you 1 degree is 17.78 (ish) mils. So 5° is almost 89 mils. So, a hair to the left of the 9 (or maybe 90) tick on your compass.

shoobe01 1 year ago
... you should be able to determine what features yours has, and does not have, and use only the skills I explain that apply to your model of compass.
Once you get familiar with it, you can then make more sense of printed manuals, and other tutorials about your compass, and get really used to it.
