    A compass with a built in inclometer. The inclometer measures heights of things or steep slopes in degrees. A compass is for direction and bearing. Let us suppose that you woke up one day on an island. You have nothing except this device. A compass with an inclometer. You have food for thirty days. You have shelter. But noone knows where you are and neither do you. All you know is that you are on some island somewhere. Let us suppose that you can send out one TELEX to the people that are searching for you. ONLY ONE TELEX. So what information would you gather up to send to these people utilizing this compass with built in inclometer??? What kind of information could you write down in a log to transfer to a telex to send off in helping these search parties in finding your whereabouts? You have at least 30 days before you have to start fishing for food or growing crops or gathering your own food. Or to be found. A wonderful thing about travel is knowing your geography but what if? Just what if???

    I&#39;m assuming that a TELEX is a standard message, not sure if there is a limit to the length. If there is, I&#39;ll rethink this a bit more.

    That said,, I suppose that your latitude can be determined with the declination of the noon sun angle fairly easily. I&#39;m not sure about how to do longitude with that, though (if I remember right, that&#39;s always been a complicated issue for sailors. Maybe it&#39;d be a good idea to log the weather, including precipitation, wind speeds/direction, and approximate relative temperatures? A week&#39;s worth of data may help a bit, especially if you can focus along a certain latitude.

    Stupid question... but supposing I didn&#39;t fall out the sky with my company telex directory - would I know the appropriate address?

    Well lets see, since I have food, water and shelter, I suppose the first thing I&#39;d do is to hike to the other side of the island to see if there was a hotel over there. Hey, you never know, and it never hurts to have a good look around.

    So the question is, how do I find how where I am?
    Well, to do that, I would wait for a nice clear night; find the North Star and then use my inclinometer......that&#39;s it, I&#39;m done!!!!!!

    No trick questions with the TELEX thing, and no, you don&#39;t have an address, just some number to send it off. Finding latitude is a great thing. You can find it via the POLARIS or NORTH STAR and the sun. (But with the sun, you have to have that moment when its smack overhead) It&#39;s easier using Polaris. So you have a latitude but why stop there? Why not jot down various stars at various times? (I think the more info the better.) Jot down the moon height at various times too using the inclometer. You can use your compass to get the bearing for the particular time. Log down the time and position of each reading.
    How about looking around your enviroment and see the vegetation? Is it tropical, is it more subtropical? Is it mountainous? Is the island flat? I&#39;d take a reading of the highest point on the island and draw a map of the island as best way possible, feel the temperature of the ocean.
    To find longitude, you need a good watch and know the actual time of GREENWICH. But it doesn&#39;t matter. When you send in the telex, make sure you describe wheather it is day time, night time, or best to send it off right when the sun rises, and MENTION SO that the sun just rose above the horizon. The smart searchers should put two and two together with their time and know the time difference based on your information for a rough estimate of your longitude, and they should have alot of information to find you now with latitude, longitude, map outline of the island.

    But this is not over. We are ASSUMING that we are NORTH of the equator and POLARIS is visible, but what if we are somewhere SOUTH of the equator. How do we determine our latitude then? I was hoping our friend DOWN UNDER could shed some light here. And, we do need to know our time don&#39;t we? We don&#39;t know what time it is. Lets say we do have a watch in the party. How do we determine TIME??? Pretty much food for thought. The next time you talk about going to 5th and sax in NYC shopping, kind of makes you wonder how you got there in the first place. A pilot on a plane with the coordinances punched into a computer, not to be taken lightly. Be glad you got there instead of somewhere out in the Atlantic ocean.

    Uh-huh, just as I thought, as my old scout leader use to say, "the key to finding directions at night is finding that "North Star".
    Which leaves our buddy Nick pretty lost.

    Our buddy Nick follows the SOUTHERN CROSS and ends up in Tasmania chasing the Devils. I dropped out of the scouts like after three meetings, so I didn&#39;t pick up beans there. Where I learned how to read a compass was in BOOT CAMP. It was a LENSATIC COMPASS and it wasn&#39;t like find the north star. First, we threw a grenade, then ran to read the compass. "Look through the eyepiece, read the number, what are you reading?" That was it. From then on, I always wondered how a LENSATIC COMPASS actually worked, but I knew that was how you "SHOOT AN AZIMUTH". Then we threw another training grenade and the Drill instructor had his moment to kick me in the butt claiming that I must take cover behind the wall faster.

    Hahaha like I could navigate by stars! I used to have an SAS guidebook which told me how to use my watch as a compass based on the sun or something. And how to make a Punji Bear Trap... but those details are a little disgusting to repeat.

    So my question is.... I take it I don&#39;t have a telex re-printer? Whenever I send a telex I get the Z time printed on it

    The saddest part of this is I know how to send a telex...

    EDIT - Do AA and CO still use them? Or is CX the only one stuck in the 1800s?

    We used to have Telex on ship. Other ways to send messages was through SONIC but don&#39;t know if your airlines utilize those. I don&#39;t know if we use telex per say anymore.
