One of the advantages is the ability of these devices to transmit a local tracking signal that can be "sniffed" by rescuers.
This Sunday there will be a Radio Direction Finding session held in Southern California.
Here is the information from the So Cal ARDF group
The weather forecast looks good for our next on-foot direction-finding session
at the Santa Fe Dam Recreation Area on Sunday, March 13. There will be
entry-level two-meter fox transmitters for beginners, a 5-fox two-meter
international-rules course of low to moderate difficulty, and an
antenna/attenuator building workshop. If you want one of Marvin's kits for
antenna and/or attenuator, please send e-mail to firstname.lastname@example.org right away.
Daylight savings time begins on this day, so set your clocks ahead one hour
Saturday night so you won't be an hour late. Kitbuilding starts promptly at 10
AM, followed by the beginner hunt. The main 5-fox hunt will commence at 10 AM
also. Hunters may start out on the courses at any time until 1 PM. Courses
close at 2:30 PM.
For the advanced 2-meter course, orienteering flags and electronic scoring will
be used at each transmitter. If you have an "e-stick," be sure to bring it.
There will be a $7 donation for the advanced course to cover expenses related to
the use of Los Angeles Orienteering Club's e-punch equipment and maps ($5 for
LAOC members). No donation is requested for the beginner course and the
80-meter transmitter hunt.
