MecArmy CMP/CMP2 Mini Compass- Meaningful Graduation Birthday Gifts for Men Women, EDC Titanium/Brass/Copper Pocket Compass for Hiking SurvivaI, IPX5 Waterproof, Glow in The Dark, Necklace Pendant

I’ve been carrying one of these on my keychain for a good while. I ensured that the split rings I used were brass (as they could throw off the reading). My son, who is in the National Guard, has one of these on his keyring and his girlfriend was given one by me as a gift from me to welcome her to the family. Make no mistake, this isn’t a toy…but the real thing. I own some of the most expensive and accurate compasses you can buy and I can tell you from personal experience, this one is well built, very accurate and won’t let you down.

Looks nice and works well. Nice to carry round neck when in wilderness.

Great compass! Easy to read. Super useful if you are directionally challenged, like me, even with GPS. Especially helpful when GPS can't get a fix on you, but you can get your eyeballs on a map, or have an idea of which direction is highway. BUT! Don't use the fake hematite necklace that comes with it because it is made of a ferrous (magnetic) material. You can use a non ferrous metal lanyard (sterling silver, copper...), but I prefer para-cord with a breakaway knot (no magnets!). 4.5 out of 5

I bought this compass to hang on my pocket knife with a plastic quick disconnect link and some paracord. I was impressed with its weight and apparent quality of construction. Despite what some are writing about the included chain being ferrous mine was not. Even wadded into a ball and placed next to the compass the chain did not affect the operation so it's definitely not made of ferrous metal. Regarding what some are saying that the pointer jumps around a lot. The compass (any compass) needs to rest on a solid, flat surface to read correctly. The trick is to slightly tilt the compass to bind up the needle a bit then lay it flat and it will point north in a nanosecond. It's all in the the operation. This seems like a pretty good unit for giving you rough headings. I wouldn't use it to navigate with but just for getting your general bearings it seems to be pretty good.

The only thing that was a little negative was it was a little smaller than I thought but overall, I’d say it’s 100% home run. It even comes with a chain and a really nice plastic box that can be used to something else.

I put mine on my keychain. It is sturdy and looks great. They would make wonderful gifts. Small and effective.

I first ordered two of these. They quickly acquired a direction only approximating North. Worse is the fact that the two differ in direction (as near as I can tell on a small button compass) by about 15 degrees! Well, a button sized compass understandably already limits its usefulness to general backup orienteering, but these can't even find North! I thought to give MecArmy a second chance and ordered two more of these hoping that I might have received unusually bad outlier units missed as faulty during assembly (bad QA/QC). Wrong. The next two display the aggravating characteristic of taking forever (many, many seconds - and never if holding by hand due to reasonable hand instability) to stop oscillating back and forth before finally settling into, again, bad approximations of North. The units look really nice. I bought Titanium for looks and durability (its non-magnetic and strong). I bought these to make "Ranger/Pace Bead" assemblies with attached titanium compass and titanium whistle for Christmas Gifts. I can't give these out because they are not even close to useful. Unless MecArmy contacts me after reading this and replaces these four units with functional ones, I must warn all that these are expensive eye candy that no one should entertain trusting in an emergency situation as a backup compass. I have to keep one of the four as I already incorporated it into one of my Christmas Gifts and is the least bad (withing -2 degrees of magnetic North). The other three I am returning since I'm not getting any support from seller via Amazon. I submitted pictures and movies showing the issues, but they got stripped from this review somehow.

This product seems like it was made really well. I really liked it and how it felt in my hand but I didn’t know the compass part unscrews. I put it in my keys and by the end of the first day I looked at it and it was gone and was just the frame and I couldn’t find it anywhere.
