  1. The declination or variation can be determined for your area by doing this: with your heading in settings set to true north, look for a way point you have saved a couple miles away. It will show distance and bearing to it. Change your heading to magnetic and look up the same way point. Subtract the magnetic bearing from the true one. This will give your variation, and if the number is positive, it is an east variation.

  2. There is an android app that will do this. GCC, Geocache Calculator. When you start the app, choose Coordinates, then choose Intersection Distance (Three), which let's you enter the coordinates of 3 points and distances, and calculates the intersection of the 3 circles: Trilateration. There are other good tools in this app.

  3. With regard to geocaching, those caches with Projection of waypoints or navigation should tell you whether to use True or Magnetic. Other issues to consider are the age of the cache and of the firmware in your GPSr.

    When I placed my first multi-cache with Projections (3 total) in 2003, the local Declination was 13.33 degrees E. Now it is 12.11E. I set these caches using True North.

    My first GPSr, bought in 1997, has firmware that calculates Declination, which at the time was local 13.76E. Some GPSrs let you set the Declination to update for changes over time.

    If you want to see what Declination your GPSr uses in your area, look at the direction to a waypoint in True, then convert the setting to Magnetic and subtract Mag from True. If result is positive,then you have East Declination. Some GPSrs do not show fractional degrees, so for more precision, use Mils and convert to degrees: Mils difference times 360/6400= Declination in Degrees.

  4. Even in my area where there is not much rain or humidity, with good containers, there can be water. The critical item is the log book. I have replaced some of my soggy logs with waterproof "paper." I bought some TerraSlate. Not paper,but types of plastic, other brands include: Duro Copy, igage, Adventure paper by Natural Geographic. They do not tear or let ink bleed through. Some are used by divers under water. If you want your log books to last 100 years, use these...

  5. Change to mils in the setup, then convert to 5324 mils in your projection bearing. This is equal to 299.475 degrees, so will be much closer. Mils has 6400 points in a circle for greater precision.

     

    LOL. That's like measuring a chainsaw cut with a micrometer. How is being more precise than the creator of the cache going to make the result more accurate? Perhaps the actual setting should have been 299.667.

    If you understand how projecting a waypoint works you would know that the object is to find the cache which is at 299.5 degrees. Using degrees the GPSr allows only 299 or 300 to be entered. My method gets you much closer to 299.5 when you are in the field and only have your GPSr. This is how I would do it. Please explain your solution.

  6. I have a logbook that lasted 9 years before getting very wet and moldy. It was a small spiral note pad In a good container but the problem is that paper will eventually get wet even here where it hardly ever rains. The solution is good paper. Other logs I have been replacing with Rite in the Rain paper. I just got some Terraslate to cut into strips and staple to make log books. This and the other plastic type papers are water and tear proof and marker pens do not stain through. You can write on these papers under water.

  7. Try using REI desert gaiters that cover your socks and most of your shoe/boots. And their convertable pants that you can zip off/on without removing your boots. I use low top light boots when off road biking because I am walking it up all the steep hills. (Watch for the goat head thorns here in So. Cal.)

  8. I also got mine from the sale from REI and I am still getting used to it.

     

    I am curious what the owners of the 6X0 what have they assigned to the extra button besised the power button??

    For the extra button, "User" key, I like setting the single tap to toggle screen lock. You can also program a double tap and hold for this button.

  9. I got the 600 at the REI sale on Friday. I like it, even with some learning curve coming from 3 years using the Etrex 20. 3 days of hiking, mountain biking and caching, and configuring the profiles and everything the way I want it. Compared to the 20, bigger, little heavier, less battery life, but the tradeoff is many more features, bigger screen and resolution, faster processor, compass, etc. I Loaded maps, PQs, everything working. Its a keeper. (My 8th unique handheld GPSr since I got the Garmin II in 1997....)

  10. I got the REI flyer and was thinking of getting this.. I have been using the etrex 20 fo all my hiking and biking for last couple years and really like it, especially the battery life. But now I am looking at the new 20x and 30X which have better resolution, more memory and features with same battery life.

  11. OP, are you sure it is coyotes?

    In my area, I would suspect raccoons. They get into everything.

    While camping recently, the foxes would steal anything they could carry. Walk 15 feet away and they were on our stuff.

    The answer has already been given: ammo cans.

  12. The concrete idea is good.

    I used my metal stamp kit (letters and numbers) to punch the geocache number on the lid and can.

    I also glued rocks to the exterior. Covered all sides with rocks about 2 inch size. You can use epoxy but silicone caulk is very strong. Then spray flat camo paint.

    However after having cans taken from my regular caches, I recommend them only for multi-caches.

  13. Now looking at your track points carefully, I see that it is reported in Zulu, and that you are not far off from 0 Longitude (positive, so east of 0 Degress, and one hour later.) Red90 is correct, your local time is 1 hour off. So, all looks good with your file name and track points. When you use a geotagging program, just make the appropriate time adjustment if your camera is set to local time.
