Like to travel with my camper. Like to have something to communicate
with my kids (and viceversa) when some of us stay in the camp and the
other stroll around (3-5 miles). Should be freely operaing in Europe,
RUGGED (bumps, spray), have a standby mode with low power consumption
but being able to "wake up" when called from the other ... any
maker/model suggestion ?

Thank you very much. Bob

PS Rechargeable from the car abttery would be very nice or rechargeable
AA or AAA cells.
