Grenade style pin that could be used to start your GoPro when you don’t have the time to take off your gloves and mess with your phone or your camera.  If you aren’t just filming all day and you want to catch something quickly, this could do the trick.

Originally designed to allow “deployment of a parachute or pulling of “flags” to start the recording of the camera. Perfect for environments where WiFi is prohibited and a hardwired, mechanical solution is necessary.”

…do you think this a product worth exploring?
