7/12 LRP PDX - Instructors Needed

[pfcs]

Hel! When I instructed with EMRA, I used four feet of 1/2" clear plastic hose with one end stuck into the side of the student's helmet. It was kinda 1 1/2 way communication-he could hear clearly but needed to REALLY shout for me to get it.
But it was infinitely better than nothing!

EDIT: if you want hi-tech, you could use two hoses!
