Liz,
YMWV, I used these throat microphones a while back (3 years ago?). I bet that
the technology has changed (hopefully improved). My Motorola FRS’s had a
tremendous range (I think they must have been illegal); at some point we used a
pair to communicate in very mountainous terrain at over 2 km (to report an
accident and to summon a ski patroller), but you don’t need that.
If you settle for FRS (or anything similar), beware of cheap imitations. The
more sub-channels and codes you have, the better chance that you won’t be
interfered with by someone else.
I cannot imagine that you would not be able to find something light,
weatherproof and with the range of 50’ (usually, the actual range is about half
of what is advertised).
As I suggested before, BT is probably not the best option (because of the
limited range).
Your problem might be that the gear you want is not the cheapest.
Motorcycle users use this type of communication all the time, so I would start
there.
good luck
Marek
