Anyone got/use a hand-held GPS device? As I prepare to go into the forest here on Vancouver Island hunting mushrooms in the fall I was wondering if they are accurate enough to re-find good spots. They'd need to be within a few feet.

They'll refind within a few minutes pretty damn accurately - the best demo I've seen was someone driving around a roundabout about 15ft diameter, and a nice circle appearing on the screen. But over time their accuracy drifts, so if you followed a route and then returned to your starting point, there's no guarantee the trace would join up more accurately than 10-20 yards at best.

Interestingly the small GPS's used in Yacts and Fishing boats tend to be more accurate than Admiralty Charts, at least on the smaller chart scales.

Never fix your "way points" to directly at a Navigation Mark - Without a good look out and change of course you could end up with loud expensive crunching noises !

Fact - I've cox'ed the marker launch in some Radar/GPS surveys on the Medway.

Years ago I taught map and compass classes in the Mountaineers in Washington State (the basic climbing course). For all that GPS units are the way to go now, it pays to know how to use the map and compass and to carry them with you. I do hope they're still part of the Mountaineer's 10 Essentials list. Yup. Did a quick search--on the Mountaineers 10 essentials list, numbers 1 and 2 are still map and compass.

Depends not only on the number of satellites that you are receiving information from but also which ones they are. The reason for that involves spherical trig, so it can be a little difficult unless you are fairly good at math.

The short answer is that the accuracy you read on the GPS is fairly accurate, and can vary from the above mentioned ± 2M to around ±15M.

One other thing that should be mentioned is that for maximum accuracy in re-finding a spot, mark your position and find your position in the same data system. GPS's will convert between different ones, but I've found that it does introduce another error.

Good luck! I carry mine everwhere!

The military released them originally for public use with a built in error, so they would have the advantage, in a war!! However the later models, are more accurate, and some companies sell ancillary bits to remove this error. I use an LMS 240 on my boat, and I find it's spot on, but I always back it up with visual notes. Do the same, and you can't go wrong.

I have one, but rarely use it. Too much trouble and too slow to get three satellite fixes when I can pull out a compass and triangulate to within a few meter on a topo map in less than half the time.

Like SRS, I worry about dropping it. Or the batteries going dead without having replacements. Either of these things would happen when the need for it was critical.

If I needed to send someone my location I'd prefer a GPS since I don't know how to use a sextant. But if I'm lost there are other ways to show your location.

If you're looking to locate your patch of mushrooms, though, I'd suggest a map something like Cap'n Kidd used to show where he buried his treasure. A good mushroom patch is very much the same thing!

Gargoyle/Rapaire, I can read a map, learned in the Boy Scouts and have a passion for them bordering on obsession. However, they don't help at all in finding one's way back to a square metre of duff in the middle of the forest -- millions of trees that look almost exactly alike! (As a matter of fact, I can't find a decent map of Vancouver Island anywhere). I need something that will record where I am precisely so I can get back to the same spot a year from now. I thought a GPS devise would help. What should I be paying for one anyway, and do they need maintainance?

I know how to navigate by the stars, use a sextant, etc. After the first batch got over the growing pains and the feds released the other satellites, GPS is the way to go. Combined with an electronic emergency signal or EPIRB, it makes sailing a lot less risky. Not that I don't trust my own skills, but the best great navigation can do for you in an emergency is to give you the satisfaction of plotting exzctly where you died.

You can make yourself your own map, diagramming landmarks and pacing off distances. This will certainly date me, but in my Forest Service days of drawing maps (I drew lots of them to document reforestation surveys, thinning surveys, planting patterns, etc) it was a simple matter of choosing a point to start from, choosing the direction you were going to travel, watch your compass as you travel in that direction, and count your paces. We used "chains" as the unit of measure back then, sixty-six feet, and my pace was 13 1/2 paces per chain. Now they use 100' engineering tapes, but regardless of the unit of measure, simply measure the distance, make several passes to figure how many paces (the full stride, right, left, right) travel that distance, then keep count as you walk and make notes. If it isn't intruding on the wildness of the location (or advertising your spot) you could even build a cairn or use a bit of flagging down low at intervals to look for when you return. It isn't difficult.

If you find the mushrooms then make the map on your way out, every time you stop, TURN AROUND AND LOOK TO SEE WHERE YOU WERE because you need to see it from both directions or it will be difficult to find when you try to return even with the map.

Way back in 1963 my pace measured 104 steps to 100 meters, or 26 paces to 25 meters. Oddly enough, every time since then that I've had the chance to check the pace it's been exactly the same. (That's measured going and coming over broken ground.)

You'd be surprised how accurate you can get with a compass and pacing (no map).

I'd be willing to bet that the USGS has a topo map of Vancouver Island. I doubt that it would be considered classified military secrets, either.

The plastic flagging denotes different activities for the Forest Service and other forestry related organizations. Blue is used for partial cut areas, yellow for clearcuts, if you happen to be in or cross over an area laid out for logging. Other colors have to do with surveys and such. The idea is not to decorate the forest like christmastime with the stuff. A small piece (a few inches), not a huge long hank of it, placed at (for example) the point where you stop going one direction and change your course, is useful. A cairn would be less obtrusive, less obvious to all but those who are looking for it. Or look for landmarks that aren't going to go away easily and thus leave little trace of your travel.

Flagging comes on rolls with a hollow cardboard center of about 1 1/2 to 2 inches. The roll can start out about 5 inches across, and was usually first placed in the large side pocket of a cruiser's vest. As soon as it was small enough to fit into the breast pocket of the blue workshirts we typically worked in, it was put in there. Button the pocket, let the end hang out the top corner, and it was really handy to just pull the end, spinning the roll in your pocket and pulling off a chunk. Despite the convenience, it always felt a bit odd because it was rotating around my left nipple. (o) (o)

Yes, I know precisely the kind of forest you're talking about. I crave getting back to that climate from the heat of the Texas prairie. I'll trade devil's club for ticks, chiggars, venomous snakes, and 100+ degree days any time! Heck, that's why I'm laid up this month--I had my bunion fixed so I can hike again if I ever get back up there!

I just picked up a Garmin unit a couple of weeks ago. The salesguy said (and I have no real reason to doubt him, since he said this after I bought the unit) that the local National Guard troops who were being called up for overseas duty were advised by their NCOs to put the government issue GPS units in the dumpster and go buy a civilian model because they were more reliable.

Who is "you," Gargoyle? I've used all of those things. P-lines (preliminary lines) in the kind of forest he's walking through can just about finish you off. If you're planning a road you have to go over everything in the path along the proposed center line, often along an elevation contour, and it can be rugged. Why not suggest he run a profile from his car to his mushrooms? In my Forest Service work it meant you went straight in one direction up or down everything in the direct path of that bering until you had a clean shot from one point to another, with no ridges or such interfering with the movement of the cable that might be thousands of feet long (for a logging system).

Best for him to walk where it is easy to walk, marking landmarks as he goes, pacing it off, and if a marker is necessary, make one (as described above).

Fastest way to find where he is is to climb a tree and triangulate from there. Assuming there are any that are the suitable size for climbing (small enough). (I can't recommend a laundry cleaner for removing all of the pitch from your clothing if you do climb a tree--so climb at your own risk!)

I have a GPS310 by Global Positioning Systems, UK. Cost about 100 UKP and I am very pleased with it. What sold it to me rather the the cheaper Garmin unit was that it did UK grid references as well as lat/long. Not much good in Canada I know but...

The lower price ones do not guarantee the accuracy that The BPL needs though. I think mine only promises to be within 15 metres. Go for a more expensive one if you need pin-point stuff.

My mate Ged said more or less the same as Garg the first time I used it. We split into 2 parties and about 3 hours later Ged phoned us - lost! I do agree though about the ability to use map and compass. I use the GPS as much for fun as anything - It realy is good to have two sets of references. But I guess I realy am paranoid;-)

Nice bits of kit, but crap in cover - never trust your life to one! As has been said repeatedly, learn map & compass skills and work out your pacing until you can do it in your sleep, then carry the GPS as a backup.
Too many people have got into serious trouble relying on GPS. Besides, the false sense of security they bring tends to bring out the worst sort of people into the cuds. A bit like the effect AOL had on the Internet!

There are thousands of quotes by those people about how they are first going to get your kids, then you.

California...liberal...Feinstein and Boxer as Senators...support 'abortion rights'. The right of a woman to choose, blah blah blah. But they are Soviets. They are social engineers of the first order. The mega-govt the 'right wing' is putting together is going to be put into gear by the Feinstein/Boxers of the US. And THEN liberals will discover what's really going on. The phony distractions about political correctness will be crushed under the boot of totalitarianism. What good is 'the freedom to use my body as I choose' when that body is in a concentration camp?

Study that list. Those organizations TELL YOU what they want to do. The Bushes have said Communist China is the model for the future. The ChiComs now have travelling death vans that go province to province executing 'criminals'. Tens of millions of political prisoners. That is the future of world govt, according to the CFR.

But then you all know this. Your liberal Sierra Club steals land, your liberal gay rights cause just set up a 'gay high school' in New York. Like the good old days when the 'negroes' were separate but equal. Ruled unconstituional long ago yet here it is again...a gay high school so liberals can feel good about themselves. God you people don't think things through. The right wing you froth about is just getting the machinery ready to turn over to the Stalinistas, and most of you will go happily to your deaths rather than offend the sensitivities of the Chinese troops fixing to blow your heads off.

I actually had that idea at one time -- seemed to make sense to me and I posted it here where it resulted in an interesting discussion. The disappointing upshot however, was that it would need a constant power source to work -- a source that would be combersome and hard to keep charged on a constant basis (I guess it requires more power than one might think).

Going back to the map discussion - a long way - someone mentioned geological maps. I don't know how varied the rocks are on Vancouver Island, but making notes of rock outcrops would be a good addition to other way finding methods - and related to mushroom locations, I should imagine.

Also, have you thought of taking a digital camera, and photographing important way points on the route, then saving them on the computer until time for the next trip, loading them back on the camera, and using it as a guide?

The forests involved in this mushroom endeavor are dense with undergrowth that grows quickly. If he takes the camera he should also take a tripod and a closeup lens to photograph all of the beautiful understory plants. Some of my most gorgeous photos in that sort of forest are of things like the red berries atop a vividly green Devil's Club patch. Getting far enough back from big things that can act like landmarks might be difficult (or would involve a machete).

A few points seem worth mentioning here.
  • Most GPS units are not capable of reporting their position to anyone but the immediate user. They are receivers, not tranceivers. GPS positioning used on trucks, trains and some automobiles are coupled to a separate transmitter to report their position (and possibly other information) to their respective owners. The GPS sattelites do not receive information from GPS receivers.
  • Many consumer level GPS receivers rely on a ground based differential signal to provide useful accuracy. A GPS receiver is placed on a tower at a precisely known point (lat., lon., elev.) and the difference between the precisely known location and the location reported by the GPS unit is sent as a radio signal to subscribing GPS receivers in the vicinity. The mobile GPS receiver uses the differential signal to improve the accuracy of the sattelite information.
  • If one's present position is not within range of a differential signal to which the user is subscribed, the reported location may be much less accurate than supposed.
  • Map providers such as DeLorme offer GPS devices along with maping software for your PDA or laptop computer. If your PDA and GPS receiver use replacable batteries you can be out in the wilderness for quite a long time without worring about power.
  • Separating the GPS receiver from the display technology means you can update your display technology without replacing your GPS receiver.

GPS technology is very useful in many situations but if you're planning a wilderness trip (e.g., BWCA or Quetico) you'll be better served with a good compass such as the Silva Ranger and a good set of maps. These are almost universally recommended by experienced wilderness guides.

The millions and millions of GPS devices now being mandated for new cars most certainly ARE senders. I bet each of us has seen some local or national news story about how the bad guys were caught after the stolen car was disabled by 'satellites'. Rip the things out of your cars. Disable them now. Oregon is getting ready to tax by the mile, and they'll use GPS to do it. And some states are kicking around the idea of outlawing cars more than 5 years old (don't have GPS).

Gillette just ordered half a billion tiny little RFID chips...chips to put into their products...molded into the plastic bottles, etc. WalMart has directed 100 of its top suppliers to use the chips in order to continue selling. Soon, your face will be scanned at the checkout line and your complete shopping list will be entered into the database along with the list. Satellites will make a note of exactly how many miles you drove to and from the store. The data will be correlated to the RFID chips in the hems of your clothing, to make sure you are 'safe'...to make sure you are the person who bought that shirt a month ago.

And this will be going on while American borders remain wide open to CIA-imported terrorists during this time of 'war'. The war is against you, folks, and if you play with these weapons being used against you they will blow up in your face.

I still have my Silva "Ranger" compass that I bought back in 1971, and it still works great. I guess it's an antique by now. (Even has the little metal tab for setting declination).

Did you know that you can get many topo maps online now? I remember linking to some for Naemanson when he was headed to California to visit last year. Of course, printing all of those sheets of paper and affixing them together is a risky business if you're going someplace where compass navigation might be necessary--few maps are going to be as reliable as the USGS maps.

DG, I suppose you know that if you can find older versions of USGS maps to compare to new versions that a lot of things have been purposely taken off though they still exist on the ground. This is common practice in National Parks that don't want people trying to drive on old roads now contained within wilderness areas. Rather than leave this stuff alone so people who need that information can use it, they remove it so the fools on their ATVs won't go looking for them and tear the place up. Compensation for the lowest common denominator of map readers has compromised maps for all of us.

In the US, DeLorme publishes topographic maps of most states. Get them at your local sporting goods store if the book shops don't have them. The elevation intervals are somewhat variable - depending on the type of terrain in the area that's mapped, but I've found them accurate enough for most purposes in the few states (Kansas, Washington, Oregon, Oklahoma) that I've looked at. Recent issues of these also include GPS grid markings. They are probably not detailed enough to locate a mushroom; but you can locate landmarks from which to navigate locally (and to which you can return if you stay "local enough.")

As noted above, you can also get the laptop/GPS coordinated version from them.

For a little finer resolution, I've used oil lease maps (in Kansas) which don't show much topography, but do show property lines and indicate who owns the land, with somewhat variable accuracy (important if you need permission to tramp around there.) They often show buildings - including outbuildings - not often on more general maps. With a little research, you can likely find a more-or-less local "keeper of the maps" for oil and other mineral leases, and the maps are usually not particularly expensive. Since they're "locally published" they're usually apolitical and don't try to obscure anything.

For wilderness areas, there are some pretty good "hiking guides" that can be useful at least for locating the shortest route back to a way out. Mountaineers Books has an extensive line of guides covering many US wilderness areas. (And a few worldwide – "Hiking in China" was a recent one, and the Himalayas are quite popular with this bunch.) SRS noted the parent organization above.

Other more local "clubs" that frequent your area may have detailed maps, sometimes homemade, that you may be able to obtain.

And don't forget to check in with the nearest Ranger Station every time you go in deep enough to need a wilderness map. They may have a better one for you – and they also need to know you're there before they can come in to save your a….

I bought my SO the cheapest little GPS (American) a couple of years ago - cost just over £100. Can't remember the make, might be Garmin, but it's yellow and about the size of a mobile phone. He makes good use of it, working in forrin' parts as he does. Especially last year when he took a boat up the Yangtze for 3 days and was the only non-Chinese speaker aboard. He used the GPS along with a map and could see exactly where he was and which villages he was passing.

He's off into the mountains of Kyrghyzstan for a week's walking in a few days time, and it will go along with him. It has that useful little facility of recording the trail you've walked so that you don't get lost. (This has also come in handy, he says, when on the way back from pubs in unfamiliar districts of Shenyang!)

When you switch it on after his return to the UK from Asia, you can almost hear it thinking hard for a few minutes as it tries to find its satellites. Then it asks, "have you moved more than 100 miles?"

Oh, I know maps, Sage. And did YOU know that lots of roads on city maps have been intentionally removed? Look at maps 20 years old compared to modern maps. A lot of still-existing roads just aren't pictured. It's intentional.

When the US goes to code red now, all major cities will be cordoned off. Police at first, to be backed up by the military and then...suddenly...the President will realize all our troops are spread around 130 countries around the world and we just don't HAVE the back-up needed to contain the ebola or whatever. And since WE are 'helping' other countries (precedent set), foreign troops will need to help US out. The cordons will be reinforced and the Homeland will be secure. People will be told to stay tuned to some local TV station and will watch Brokaw and Rather lie to us in shifts about how help is on the way. Then, after 3 days or so, everyone will start to get a little hungry. Within a week half the population of every major city will be dead from rioting, then the 'foreign assets' will move through and mop up. That is the plan, folks. If a code red is ever announced, you have two hours to get out of your city.

So learn your back roads. The highways will be blocked first (why do you think concrete barricades left over from that last construction job are still in place?), and after the highways are blocked they'll start on the back roads out of the cities. So hit the backroads with an old map. And old map because a lot of the little connecting roads that could get you out of cities just AREN'T THERE on newer maps. Intentionally. To thwart escape.

The coming massacre has been in the works for decades. You have to go back at least 20 years to get a true map, but between that and a new one, most of the existing roads should be pictured. And map out a couple of escape routes now, folks. Or buy guns and food.

OK, so between now and when the US government takes over Vancouver Island, my origianl question was 'will a GPS help me REfind a spot in the forest?' And I'm beginning to think it will, at least it will make it a lot easier than relying on memory or using a map. The problem with maps is that they are not as useful in this situation as some seem to think. Imagine standing on an undulating piece of earth with no buildings, outcrops of rock or mountains. Now fill it with trees that look exactly alike. Now put fifteen more trees between you and the trees. OK, now you're looking at the ground for mushrooms while you trundle through it all. What use is a map even if such a map existed? At least a GPS lets you know how many numbers to the left you need to move to get back to the right coordinates. Downside of course is that it also lets the Taliban know where the tricoloma magnivalere is fruiting.
