I've checked the terminals, I've run the upgrade several times, but it is still dead. Is there anything more I should try, or should I just accept the loss, and go shopping for a new one?

I have tried with new batterie, not lithium, but alcaline. Still no response.

I havent been wery active the last couple of years, but some friends of mine have started geocaching, and suddenly I wanted to get out to find some caches myself.... The problem i s that my Colorado is dead, it will not boot. If I connect it to a computer, the display lights up and I can access the files and folders on the unit, bet when it is disconnected is is dead ( I have checked the batteries ). Is there a way to reset the unit 100%? To copy the original files and folders in the unit and delete everything else? I might have made the problem vorse by trying to path up the system my self. Hopefully you will excuse my misspellings and grammar faults, English is not my native language.. Regards from Norway Hallaron

My main hobby for the last 6-7 years have been sailing. Navigation has been, and is, a big part of this, I have taken several courses about sailing and navigation, and my understanding of maps, coordinates and navigation have become rather good. On the other hand, my job requires a lot of travelling, and I have seen enough of hotel rooms to dislike them.. The next few weeks I will be travelling 2000 km north and 3000 south, visiting at least 4 different countries....... So for quite some time I have been thinking of starting geocaching, and some weeks ago I went of and got me a Colorado. My goal is to see less of the hotel rooms and more of the nature around me. So far it has been a success! Is it more than a game? Yes I would say so - it is a way of getting more physical training and it sure is a way of seeing more of the beautiful nature around me. And right now I get some training in writing English, which I don’t do too often.... Please excuse me misspellings and grammar errors...

Me? Was born just some days after Armstrong was out walking the moon.... ohhh I'm soon to be 40? Caching solo, hope some of my IT friends will get interested and join me....

Slightly off topic, I know, but ... a variation on the old classic "Physics 101" exam question: Q: You need to determine the height of a high-rise building, using the navigational aids available to you. How do you go about this to achieve the best accuracy? A1: Just read off the contours on a topo map and .... Oh, wait a minute, that won't work! A2: If you have an uncalibrated Casio watch with a barometric altimeter, you can take a height reading at ground level and another at roof top level. Readings are in 20 foot increments, so your estimate will be good to about 40 feet accuracy (12 metres say), 20 feet (6 metres) at best. A3: If you have a GPSr without a barometric altimeter, take GPS elevation readings at ground and roof level. Rooftop reading accuracy will probably be "pretty good" (by GPS standards), due to good sky visibility, but ground level accuracy may be poor, due to shielding and multi-path errors. Height accuracy probably no better than 30 to 50 metres say. A4: If you have a modern GPSr with a properly set-up auto-calibrated barometric altimeter, take elevation readings at ground and roof. Height accuracy will be good to about 2 to 3 metres. (Yes, it will continue to give good height accuracy as you go up in the lift, even though you will lose the GPS signals.) A5: Another method which will work with any kind of sensor - get a long piece of weightless string, tie the watch / GPSr to the end, and swing it as a long pendulum from the roof of the building to ground level, and measure the period. Weigh the watch /GPSr. Basic mechanics will yield the length of the pendulum, and hence the height of the building. A6: Take your watch / GPSr to the roof of the building, and drop it off. Time the fall to ground, and calculate the height of the building (taking into account gravitational acceleration and air resistance, etc.) (Note: Single use only - make sure you set your stopwatch accurately at the start and finish of the drop!) A7: For really accurate height calculations with ANY type of measuring instrument - find the building owner. Offer to give him your watch / GPSr if he will show you the building plans, so you can read off the exact height of the roof. Sorry, I couldn't resist! A8: Since GPS basicly is a navigation aid, we should use an old navigation tool to solve the problem: a sextant to measure the angular height of the building, then measure the distanse between the building and you. Then it is just to do the math, and you will have an accurate measurment of the height.. PS. Forgive me the missspellings and grammar errors. As you probably can se english is not my native language..
