Let me show you a military signaling technique known as the buzz saw what we do is usually we carry chem lights on us because we can mark things stuff like that it can also be used as a military signaling device so what i have here is cordage taped to the chem light tethered out about three foot.

Will crack the chem light in low light conditions and then swing it in a circular pattern and it'll create a buzz saw or circular saw kind of strobe at night time now we can use night vision goggles if we want to be discreet and our partners have night vision goggles and we can use an ir chem light that can.

Only be seen by night vision goggles another thing we can use is the key chain flashlights like we saw in our store the red ones and you can tie it on a string and then swing it and it creates the same type of system and you can carry this in your keychain of your survival kit
