[Az-Geocaching] Cache Clash~ digress to SAR

I have found that most SAR teams, at least the ones I have been with,
prefer the UTM method. Unfortunately the helo’s that we work with use
lat/long. We usually run with one GPS in lat/long and one in UTM so we
don’t have to change the settings for the command post.

SEE? Thanks Dirk!! I knew that someone from "flatland' SAR
(Phoenix/Tucson areas) would know UTM very well. We don't use it up here
(yet) in Yavapai Co, but we have had to learn it for when we work a
large search with units from your areas. The first time a Maricopa Mtn
SAR guy reported his position in UTM to me on the radio (on the Lake
Mary search about 5 years ago, and btw we did find the 2 brothers alive
after almost 3 days in December freezing weather!) I turned to my Capt,
who was ex-Marine, and immediately had him start plotting positions. It
was especially important as it was the middle of the night and these
specialized rescue teams were being inserted along the sides of a steep
canyon (Mormon Cyn) so we needed to be sure we had good position
reports. But, I digress....

du/dutchs/FieldMethods/UTMSystem.htm
this site is very informative and explains how UTM works. UTM would look
something like:
12S E 385060 N 3704249 for the Drinking hole cache #16
or the DMM we know as N 33 28.293 W 112 14.220
The reason it is easier to determine distance on a smaller scale is UTM
is metric, so lets say someone gave you those numbers and told you to go
100 meters west.
With UTM the coordinates would become:
12S E 385160 N 3704249
while in DMM it would become:
N 33 28.293, W 112 14.155
It is easier to add to metric in UTM or subtract then to try to figure
out the distance in Lat Long..
.001 degrees in Long for the Flagstaff area is about 4.9 feet while .001
degrees Lat is about 6.07 feet
In Tucson the distances are 5.15 feet for Long and 6.07 for Lat
The differences are minor, but in some areas DMM formats are much
different then in others.
Most GPSr units can handle UTM and you might find a good bit of help on
some projection and calculation type puzzles by trying UTM instead of
Lat Long. :)

OK, so for those of us boneheads that don't know what that means, could
you tell us what UTM is? I could Google it, but it's so much more fun
to hear it from the "pros".
