IMHO, all of these electronic compasses in the wrist watches are not good for navigation simply because the sensor used in them have something like 50 positions, i.o.w. its like ~7 deg. precision. You can tell where the North is, but I doubt it's good for any serious navigation by azimuth bearing in the field. Also take a closer look at those "cool" bezels on them. Marks every 30 deg.? Almost any analog compass is better.

Avoid single point of failure to multiple systems; Single item,i.e. cell phone fails,now commo fails,compass fails gps fails etc. Agree. Redundancy, Redundancy, Redundancy. Small button compasses (on key chain, in pocket, etc) and a flat navigation compass in the glove box of car, and in the car's BOB wouldn't hurt. I got a little LED light/compass combo for my wife, child, and aunt to put on their key chains for stocking stuffers this year(now to go get one for myself now that I've taken care of my loved ones).

The way I see it, you either need a good compass, or you don't need a compass much at all. If you need a compass, you'd be wanting to triangulate your position on maps, site bearings, etc. You won't be doing that with a cellphone program, or even with a button compass. I think putting all your eggs in one basket with a cellphone, or ANY electronic device, to save pocket space is terribly foolish.
I can see a button compass useful in some situations, none of which generally apply to my routine hiking areas (in the mountains). If you were in deep woods (flat land), or maybe in a desert it would be nice to not go in circles and a semi-accurate button compass may assist in that. In the mountains your heading is determined more by the terrain you can navigate than by a specific bearing.
Personally, I always carry a good, fullsize compass and topo maps. Every hike finds me triangulating my positions, identifying landmarks using a sited bearing and the maps, etc. Not because I need this for navigation usually, more just to keep my skills tuned up for when an emergency may mandate pre-mastery of these skills.

haertig is dead nuts square on target! A compass is a powerful tool, but its power only comes when you can use the compass to relate your position to a know landmark - or two. For that you either need a really good map of the area or a GPS with saved key waypoints - or preferably both. A compass without a baseplate straight-edge is really really tough to work with in conjunction with a map. The compass is not the place to save weight. Bring a decent baseplate compass (I much prefer one with adjustable declination), a good map of the area (USGS topo map in the US), and, hopefully, even a very simple GPS w/ extra batteries. Save key waypoints often and know how to convert coordinates on a map to a waypoint on a GPS (see http://wwww.maptools.com ). I'd actually put the good map ahead of the compass in terms of utiliy. Many outdoors folks will tell you that they primarily travel using a map alone, but certainly at times need to use their compass to confirm their location or direction of travel. I flew out to Charlotte, NC during the last few days and brought along a copy of the book "The Essential Wilderness Navigator: How to Find Your Way in the Great Outdoors, Second Edition" by David Seidman and Paul Cleveland. Its the second time I've read through it and I have to say I'm pretty darn impressed. Its one of the few books on the topic that explains BOTH how to use compasses with adjusted magnetic declination AND how to use compasses that are not adjustable for declination. I think its now my favorite book on the topic. Ken K.

Even in deserts, you rarely need a compass, because you are surrounded by obvious landmarks, at least in the continental US. You will need a compass for navigation when your visibility is restricted (fog, typically) and if you are at sea. I can count on one hand the times I have seriously used a compass in the mountains, and both times we were in the clouds.
But if you are going to carry a compass, carry one that is marked in at least two degree increments and that has a sighting (signal) mirror. Plenty are around that weigh maybe an ounce. Very easy to carry. If you use it much, you will want it on a neck lanyard., and not in your pockets.

I wouldn't trust to landmarks for any forested area. Around here people get lost in the woods all the time...usually the ones who don't have a compass or GPS. You can walk a LONG time and never see power lines, cut line, trail, road, etc in Alberta. If you're disoriented it's even worse. I've heard of people getting lost within a km of their truck or ATV and wandering for hours going in circles.
At least with a button compass you'll keep walking in the same direction.

I agree with you Dave about a compass being mandatory in thick forested areas, it has saved me from a night in the bush many times. I often use the sun as a direction indicator when I am just cruising around during the day but when darkness is closing in and I need to get to where I am going, I flip out the Silva Ranger to get the job done.

So many survival situations start with someone getting lost. Going small cheap with your compass is a bad move IMO. YMMV, but you're probably wrong.
