Base Plate Compass, "every" part identified and explained

Here is a list of EVERY part and function on a standard Base Plate Compass.
I did an internet search this morning and there wasn’t one single website or video showing “every” part on a Base Plate Compass so I thought it would be interesting to make a video, so at least the information is out there.
This is a long video so if you want to fast-forward to a particular feature, here is the order they are described. You can "click" the time to jump to that point in the video.
1. Direction arrow 3:20
2. Luminous pointer 3:50
3. Romer scales 4:15
4. Bezel/dial 5:35
5. Orienting lines 6:09
6. Ruler (imperial) 7:08
7. Magnetic needle 7:30
8. Risers 8:15
9. Lanyard attachment 8:50
10. Orienting arrow 9:15
11. Ruler (metric) 10:00
12. Declination scales 10:15
13. Index Mark / Line 11:35
14. Hole with crosshairs 12:10
15. Parallax Line(s) 12:50
16. Magnifier 14:10
17. Label holder 14:35
18. Sighting hole 17:20
19. Sighting mirror 18:10
20. Sighting Lines (H) 19:25
21. Sighting Lines (V) 19:40
22. Index Line 20:45

When I was sixteen I'll never forget doing my Bonze Duke of Edinburgh Award in the Pennines, the fog came down whilst we were up a rather large hill on a peaty feature less landscape. Using a map & compass I managed to navigate my group down to the next checkpoint which was a phone box. It wasn't made easy when half of the group wanted to go back and I had a doubt whether they had really grasped the art of orienteering. It was one of those situations were despite explaining everything clearly they still weren't getting it, as I had the map & compass I stopped trying to negotiate and carried on and the group followed.

@ianbelletti6241 5 ай бұрын

@@kmr_tl4509 they are usually oriented to the map North, not magnetic North. The compass rose marks the magnetic North orientation. Occasionally a map is drawn to fit the area to the page in the direction the area is oriented causing the top of the map to not match North. Only limited areas of the Earth have magnetic North match the map North. That's why the compass rose is so important.

In the military, using a lensatic compass, every part of the compass is named, described, explained, and practiced with. We even have it in our basic manuals that everybody is issued, with pictures and arrows and diagrams and terms and acronyms. So im surprised that nobody has instruction available for baseplate compasses. I own a couple that I keep in some emergency gear bags, but when I'm in the boonies I use my trusty lensatic compass.

They are all issue "Technical Manuals" for the Army, Navy, Air Force, and Marines, so they are listed as "TM-" followed by the specific number assigned to that publication, and is the first line you see at the top of the cover or plate.

I didn't read the description very well when I ordered and to my surprise when I wnt to use the compass it's bezel was NOT 360 degrees nor was it in Mils. The bezel was measured in 90 degree quadrants and was set up like a surveyer's transit. Since I was surveying this worked out well once I found out how to read the survey document. I did also buy a Sunto 360 degree mirrored to be sure I had what I needed most of the time.

Checked out the site for the Swedish Silva Compass and they do have a brake down on the different parts of the baseplate compass. Been using them since I was 9 or 10 years when my dad taught me to use a compass and a map when orienteering. Later on he also showed me how to use it at sea in the Swedish vast archipelago, but then I was a couple of years old probably 15 yrs. We used military maps and compasses a lot in the military (conscripted services). Having a compass in your pocket when roaming the Swedish woods is sometime necessary and should be in every survival kit. Btw, the lanyard is also used to have around your wrist when running in the wood so you don’t lose it.

Good for you. Saw a gap and filled it. It's hard to believe there isn't another vid about this subject.

Neat - it might be worth mentioning that when measuring distances on the map (like the wall, or estimating your journey), the gradient adds distance. If that wall ran up a 45 degree slope, for instance, it would measure 1.4 times the distance on the map. The steeper the angle, the more you have to add (a vertical cliff measures nothing on the map, however high it is). If you're doing a lot of climbs and descents, this can add serious amounts to your travelled distance. I haven't yet discovered whether computed tracks on phones and GPS navigation gizmos adjust for that, but I suspect not.

Depends on what map data they have and how accurate it is. I know that google shows heights when using it for bike navigation, and it give a hunch about the extra distance. 10% gradient is very very steep, and that is 0.5% extra distance. The steepest road in the US is 37% grade which is 6% extra distance, however, these extreme slopes are over very short distances. But yes, if you are climbing a mountain (even one that does not require climbing gear) the height difference is often more interesting than the horizontal distance.

@@57thorns Wow, where I live, roads with 20-30% grade for extended distance aren't uncommon, and those sorts of slopes would be even more common in trekking scenarios, not necessarily "climbing a mountain" but just navigating several undulating hills. I agree that in doing this, the grade feels "more interesting" than the additional distance, but together they make up a double whammy, climbing and descending on a journey, so the app reporting 20% less distance than you actually traveled is just a bit irritating (or my ego is too big ;) ).
