It's called a "transceiver" or "beacon"....and yes everyone in that video had one on....it's MANDATORY on ANY heli or snowcat operation.....as well as MANDATORY for myself or ANYONE going out in the backcountry with me....

Black Diamond is where I'm sending anyone and everyone who is asking about it..... blackdiamondequ ipment.com

Hey Angie -

Miraculously no broken bones from what I know of. He was VERY tender and sore all over the place and had twisted one or both of his ankles a bit, but for what he went through pretty amazing too.

not sure to be honest since yeah it seems like if the mic was picking them up why wouldn't it with him?? and I don't think that particular models works off of two mics but I'm not familair with it....only the VIO and GoPro
