Re: Use UTM for land navigation not Lat and Long

it really depends on how you find the location on your map. If your Expert map thingie will give you lat and long,,,,and you want to put it in UTM,,,,just set your gps to the unit of the measurement that you have (how ever you get this is up to you) ,,,input it and then after it is saved in the gps you got to your setupp window in the gps and change the "units" to UTM,,,,now your saved waypoints are displayed in UTM (or what ever "unit" you choose),,,this works both ways as far as what is more accurate there is prolly a ford chevy debate for that we are talking about what is more EASY to plot by hand on a paper map,,,and that would be the UTM method BY FAR

I agree totally! I have been using UTM since 1995 and it is so much more relevant to land navigation than Lat/Lon. Good post!

Professional surveys are still done in Lat Long. Most real estate plots in your county tax assesors office will be Lat /Long. Bottom line is that UTM is easier to use as it's 10 based and we all are born with the digits necessary for reinforcement. But Lat/Long will be around for a while yet.

Most GPS gear wil easily convert one to the other, only error is the datum error.

So go learn UTM and let the gear do the conversion if you need to. Funny how Washington and Jefferson had no problems using it in their day... Maybe its just part of the FreeMasons plot to keep you confused.

It will not hurt to learn UTM but in real life, you will not get any more accuracy with it than with full length lat/lon unless you are writing readout on paper to later input it by hand. Using Software to create waypoints over a map and to transfer them directly to/from the receiver eliminates the need for reading co-ordinates at all.
