hi all

 

i dont have a GPS unit....but i have a 1945 Army Corp of Engineers Military issue compass....ancient huh??

 

now i went to some sites and found some info on how to read them but its still greek to me...i am directionally illiterate icon_wink.gif

 

on the geocaching site it has the coordinates for the GPS units...can u use these for a compass??? ...if so what do the numbers mean??

 

i do not have a computer so for the degree mark i will write "deg"...

 

N 29deg 28.679 W 095deg 20.156

 

******ok N obvious is north

****29deg---from that dial thing around the compass with that line thing??

****28.679----what is this number??..paces????

 

we tried working with the compass...we might figure it out if we know what all the numbers mean....

 

thanks for any help

A compass alone will not be much help for geocaching. You really need a GPS, or be really good with maps and a compass.

 

The numbers you are reading have nothing to do with a compass, but specify a position on the earth.

 

Example:

N 29 28.679 -> (latitude) a line 29 degrees and 28.679 minutes above the equator. (it would be a "horizontal" line across a globe)

 

W 095 20.157 -> (longitude) a line 95 degrees 20.157 minutes west of the "prime meridian" which runs through Greenwich, England. (it would be a "vertical" line across the globe)

 

Where these lines cross is where the cache is located.

 

A GPS receiver is the most common way to locate this position. However, if you're really good, you can use paper maps to find the location. A compass will be a big help in this case.

The GPS numbers you are looking at show location; sort of like your home address or the address where you work. A compass indicates direction you are traveling.

 

A compass will show you the direction to your workplace but you you won't know where to stop unless you know the actual address. That's what the GPS coordinate numbers will let you do.

 

You really need a GPS to geocache successfully on a regular basis. Hope this helps.

 

Good luck.

A compass is useful if where you want to go is 20 paces east of dead man's tree, or from one set of known coordinates to another (assuming you have determined the direction and distance).

 

If you want to get TO one set of coordinates, then you need a GPS to tell you where it is relative to where you currently are located. When in GOTO mode, a GPS constantly determines the new direction and distance.

you can use your compass, but as has been said earlier, you have to be really good with the compass. it will also help you to have a good map, a drawing compass, and a calculator if you can't manage to do the math in your head.

 

i find i'm pretty accurate with the map and compass, but i have some trouble with the figures, and, well, it's hard enough even if you have a GPS unit.

 

it doesn't matter if you get to camp at one or at six. dinner is still at six.

hi all

thanks all for the info...guess i will just have to rely on the spoiler hints at the bottom and ask for any extra hints from the people themselves who hid it and hope they take pity on me and give me someicon_wink.gif

thanks all

It can be done without a GPS, several cachers (OK, a few) locate the bulk of their finds with just a topographic map and a compass. Your compass was originally designed to help GIs find a specific spot without a GPSr, so you can too. Use the links posted above to learn how to use the compass well.

 

Beyond that, save, save, save. Yellow eTrexes can be found on eBay for about 70 bucks. I recently bought seven at around this price (don't ask!). While this is still alot of money to find in the budget, it can be a managable amount to save up.

 

See you out there...

are we taking up a collection for people without gpsrs?

 

we can send the WG$ we find to wanda. she'll have enough in two weeks for herself and one for a friend.

Try going to http://www.us.orienteering.org/ . They have many articles and links to other resources. If your library has a book called Be Expert with Map and Compass by Kjellstrom get it. I learned orienteering and map/compass reading using this book, and it is EXCELLENT. Good luck.

Hey Wanda Texas

 

Hope this does not sound sexist?!

 

But I have a book, called "Staying Found

The complete map and compass book" by June Fleming. She seems to explain things in

a more womanly way???

 

Also if you get your hands on FM 21-26 (Map Reading and Land Navigation) This is the bible of the army on all you should need to know for advanced knowledge.

Anyway it is a great basics book, does not cover GPS.
