a brain, not a hand held device that is techology.
Hand one of those to a person under 40 these days they wouldn't even know what is is.
Not even close to a GPS. GPS stands for Global Positioning System. The object in the picture absolutely cannot tell you where you are. It can only tell you the direction you are traveling in relation to magnetic north or the direction you want to travel in relation to magnetic north. And those are only true if you are using it properly.
I understand what creates their unreliable also. Plus travel a couple of degrees off and one can end up miles away from their intended destination. What about getting into natural electromagnetic fields?Squatchman » 04 Mar 2024, 8:31 am » wrote: ↑ Hand one of those to a person under 40 these days they wouldn't even know what is is.

This is my event horizon/compass for time displaced uniquely me.Huey » 04 Mar 2024, 9:40 am » wrote: ↑ WHen did you become so anal? That and a map will certainly tell you where you are. TriangulationTriangulation is the process of pinpointing the location of something by taking bearings to it from two remote points.
Forest fire lookout towers used triangulation to locate spot fires.

I added "correct" before map because if I suddenly find myself lost in Montana and stumble across a compass and a map of Australia, I will still not know where I am. Besides, triangulation is really only accurate enough to give you an estimated position. It will be off unless you are lucky enough to exactly nail the bearing directions on the fixed objects or they are close enough that a small variance between the bearing you take and the true bearing is not material. Additionally, the further away the two fixed obects are away from perpendicular to each other impacts the accuracy.
You can call that anal if you choose.
The last time I used a compass was in the early 2000's when I was lining my direct TV dish up to the satellite. LolHuey » 04 Mar 2024, 10:00 am » wrote: ↑ I have always been good with land nav.
