You know, in the woods you don't even need a compas, you can use a tree ;-)
I think that the 'issue' here s knowing/remembering where you parked the car......
Thing IS, with GPS* is that its great for telling you where you are... but not much else. Sat-Nav*, which uses digital map software to tell you where you want to get to from where you are, which it gets from GPS... doesn't necessarily know where you left the ruddy car!
GARMIN.... bought one of these little widgets for the O/H a few years back. Sort you stick in the car widscreen to boss you about and make you paranoid! HORRIBLE bludy invention for the most part, and yet another victory of technology over common ruddy sense in so many instances! HOWEVER. She was learning to ride a motorbike, so out on her own to practice and explore 'new' roads for practce, and worried about finding her way 'home'.
Gizmo is quite good in that respect, PROVIDED you have programmed it with where 'Home' is!
Ergo... whilst you might lift it from the windscreen and take it with you whilst you walk about.... UNLESS you have programmed it with the location of the car when you parked it.... it wont have a clue where your car is either!
It does 'Snail-Trail' your journey, if you have it switched on, but, that still wont tell you where you left the car..... just how to back=track until you find it! Ad on the one the O/H had, you could only review the snail-trail on down load to a PC.
To wit; you can throw a shed load of technology at this problem... BUT, it's the WRONG problem. You don't need something to tell you how to get back to your car... YOU need to know where you left the ruddy thing! If you can't tell the widget that, then doesn't matter how wonderful its positioning system may be, or astounding its routing system, it's NOT really going to be able to help you very much!
I will say that the little Garmin was a useful little tool occasionally, BUT, it's forte was its routing system; designed predominantly for use 'in car', it assumes you are IN a car, and in the middle of woods, would likely direct you to the nearest main road; round the houses, up the high-street and back to the car-park.. IF you had remembered to way-point the car-park to start with.... other wise likely offer you a route all the way home, and you could be in for a long walk!
I don't think that this is a question about devices but in using them. Garmin did have a 'Pedestrian' mode; which would calculate routes down foot-paths and pedestrian accesses, it would't offer in 'car' mode, but mapping data of them s not particularly comprehensive. O/H found using it to do her home-care rounds it frequently took her the long way about, and on at least one occasion up road where the foot-path ran out at a bridge!
Whatever 'device' you bought for the job, on ts own it wont solve the fundamental problem of remembering where you left the car; and to be of any use, it would require you employ the know-how ad discipline to log the car's position before you walked away from it, and then some more to switch 'modes' to avoid erroneous routing back, and even then, you still have plenty of opportunity for effupp!
Which begs a question.... IF you cant remember where you went since you left the car... are you REALLY going to remember to way-point the cars position and re-program the widget every time you leave it.... A-N-D if you do... is that really very much easier than not being so absent minded and watching where you are going?!?
* Sat-Nav is NOT GPS, GPS is most decidedly NOT 'Sat-Nav'. GPS is Global Positioning System, it JUST tells you where you are by triangulation of satellites; Sat-Nav is a satalite linked navigational system. Uses the sats to tell the 'widget' where you is, and then a digital map to work out where you need to go from there.
