Boy Scout Sighting Compass - Adjustable Declination Mirror, Compass Base Plate, Orienteering & Hiking Navigation - Military Grade, Backpacking & Camping Tool

This is a perfectly good $10 compass, accurate and better quality than most.I cannot understand why other reviewers complain about the declination adjustment, which is accomplished with a tiny screw on the bezel in the NE position, and a matching metal shim is provided that functions as a screwdriver. In my accompanying photo, the compass can be seen set for 14°W declination, which is correct for my area; that is, the red outline arrow (not the magnetic needle) Is aligned pointing to the 14°W position on the inner chapter.The declination adjustment screw is not a set-screw that is loosened to free something else, but is a worm screw that actually adjusts the declination: turning it one way moves the declination to the west while turning it the opposite way moves the declination to the east. Once set, the declination remains stable, which is what the vast majority of users want if they tend to stay in more or less the same area. Frankly, if you travel enough where you need to keep changing the declination, you should be spending a lot more than $10 on your compass.In normal use, the bezel is set to the desired bearing relative to true north, and the entire compass (and its user) are rotated to bring the red half of the magnetic needle into the red outline arrow, commonly described by the mnemonic "red in the shed." I didn't do that in the photo in order to give better visibility of the red outline arrow relative to the declination scale; in my photo, the bezel is set for a bearing of 130°, slightly east of southeast.The description is clearly wrong in that my compass has a 1:24,000 scale rather than 1:25,000 scale. Note that in the US it is far more useful to have a 1:24,000 scale to agree with the standard US Geological Survey 7.5-minute quad maps.The compass has an inclinometer, not mentioned anywhere in the description, but that's the tiny red arrow mounted on a freely rotating clear plastic wiper (pointing to SE in my photo), intended to point downward if the compass is held vertically and the baseplate edge is aligned with the horizon. One could in theory use it as a very crude sextant if truly desperate.You will definitely get your $10 worth.

Waay cheaper than a Silva Ranger with exactly the same features!! I'm gonna buy a second one, for that price you cannot beat it

Nice compass - accurate - good value - excellent glow ability - well built

The media could not be loaded. Feels quality enough for the price. Has a declination adjustment. No good place for the key used to adjust but you can just tape it on there like I did. The bezel felt a bit stiff at first but just give it a few good turns and it’ll be good. Overall good choice if you need a compass.

I bought these compasses for kids to use on an orienteering scouting adventure. I wasn’t sure about the quality because the price is so low compared to Suuntos, Bruntons, and Silvas - but I was super impressed once I received them! It has a sighting mirror and notch, you can set the declination with an included key and the rotating bezel does not slip. I did wish there was a better tick mark at each number, but for the price I can’t complain. Will definitely buy more of these!

I'm no expert with compasses, but this one seems to have all the bells and whistles one might need, such as an inclinometer.As the unit came without instructions, it took me a moment or three to realize that the included metal clip is what you're supposed to use to loosen and re-tighten the retaining screw when setting the unit's magnetic declination. It's a slot-style screw, but it's so small, even none of my jeweler's screwdrivers would fit it.Now, if only the earth's magnetic north didn't keep moving around. (Who knew!)

I rate this compass 4 out of 5 stars because it has all the features i want. The declination adjuster is usually only found on much more expensive compasses. You can see i set it to point slightly off true north to account for magnetic north. There is a inclinometer (circled it in cyan) hidden behind the needle that i misses at first. The numbers are clear, large, and legible, and the rullers/scales are fine. My only complaint is the quality. Nothing on this feels durable. The red dial feels like the thinest and flimsiest plastic available. The declination tool did not fit the worm screw but i was able to adjust it with a jewelers screwdriver. I'm disappointed that the components feel so frail because this compass punches above it's weight with features. I don't understand why. Plastic is so cheap to produce it would had only cost the manufacturer pennies more to upgrade, and i would had gladly paid more if this was built to last. I would not take this backpacking but it's an excellent starter compass to learn on an afternoon hike.
