So its a Marker Panel , Perry Whistle and Heliograph all in a Baccy Tin. Nothing else hiding in there? How big is the Panel? Just wondering how big a panel could be squeezed into a Baccy Tin.Along with normal stuff like map, compass and GPS, and an orange blizzard blanket, mobile phone.
In the box is a lightweight air marker panel.
+1 for the survival blanketI always carry mirror, whistle, torch, mobile, survival blanket (pegged or tied out with a torch flashed on it, not a bad night marker), means of making fire (for smoke signals by day, light at night) and leave route details with reliable, level-headed friend. So far (35+ years of hiking and camping) I've never needed to use any of it. (Touch wood....!)
