@MAG315 Thanks Mag315. That's great to know that not all digital watches cause this deflection. Now you've got me wondering whether it is a design aspect of some digital watches or a specific feature (like the size of the display face or backlit display, etc...) that makes the deflection. Any ideas?
@SkiDoc21 I tried some more of my digital watches to see if any of them would affect a compass. Out of all my Casio's, the only one that caused even a slight deflection was an old, analog/digital AMW-320. In this case, the stepper motors in the watch probably have a small magnetic field. However, my newer Casio AQ-164W which is also Analog/Digital had no effect on the compass at all. My only non-Casio was a Nike Oregon and it too caused some deflection but it has a built in compass.
Early on I was thinking I was Einstien yelling at the screen."the battery, the battery" and nope not the battery, I tested my compass against a vintage Seiko 1974 (no battery) and it effected the compass, I then tried it with a modern battery powered Lorus and it was still effected..?it would throw of the needle off by about 100 degrees? I am glad you discovered this before you went hiking or got lost cause that compass/watch combo would of got you more lost.Thanx for heads up :)
Cool video! Yeah compasses are very sensitive instruments. Try walk with it towards a radiator and it use to detect it. That much from a digital watch? Interesting...how about mobile cell phones? :)
@Velodynamic Thank you for the comment! R u serious? U r referring to a car radiator (vs an inhome, heater that uses hot water) right? I'll have to try that this weekend. Why does a radiator have such a strong magnetic field? I'll try the cell phone effect this weekend, too and let you know. Be well.
@SkiDoc21 Yes I'm pretty serious. I've been trying this at my parents house. They have a heated water system with radiators below every window in the house. If a compass is held close to them the north side of the needle is very attracted to the heat radiators in all directions of the house. I've never figured out exactly why that is happening, but there it is. :P
@Velodynamic Those radiators are typically cast iron, which does have magnetic properties, and at that size, I'm not surprised the compass can be swayed by them. I tried my cell phone (iPhone) this weekend and the screen does not cause the compass to deflect - which surprised me - but some of the buttons do, as well as the speaker (of course the speaker does, it has a magnet on it).
Thanks again for your comments! Hope you are having a great day!
@1PATRI0T Thanks! Unfortunately you are correct, the bracelet is too fat, although I'm tempted to try to flatten out a small portion in the center of the bracelet with an iron to make a mounting area for the compass. Think that'd work?
@1PATRI0T Yea, I thought about that but there's not enough room on that particular bracelet for the compass at the end. However, i could make one...but that'd take all the fun out of melting paracord! lol I'll let you know how it works out. Hope you are having a great week.
I tried my compass around my Casio digital watch and got no deflection so I'd say it's just that particular watch that causes the problem.

Pretty interesting. Could you clip it to your survival bracelet? or is the bracelet too fat?

Well, that or maybe right at the end where there isn't any of the cobra weave.
