Consists of: compass liquid filled, (work), small mirror (by installation in deep screw limited as a signal mirror usable, you have the cap probably break and possibly destroys the compass), Whistle (with ball-can thus freeze), tiny Firesteel on the outside (not tested, but is probably at least 50-100 firings create-if he goes and does not drop (neatly glued)), signal orange housing with cavity of about a finger is deep and wide, penetrating with O-ring against water backed up, you can store things there. Enough for water purification tablets, plastic bags and a couple of necessary medications, perhaps even a few matches, all on a long cord, so that it can be worn around the neck. So who takes with children in the forest, and tells you they should warble when they lose contact, and always eat a piece of candy from the cavity (which you are, of course eien water purification tablets or similar but sweets and put in the capsule!) And then trills again likely get the little problem free. But the danger is that the dear little cut off on purpose to feed the sweets ;-) Who can enable, put in the capsule to screw, a tiny lamp and has a 80 cm orange light district at night when the whole oscillates on the string. To-if you do not expect so the Amazon to traverse the jungle, but the correspondingly equipped for the worst, always the man (or woman) to have short, can already properly do with attention and with a knife and a bit of skill to improve its situation if you had an accident in reasonably accessible terrain is. Delivery was OK, so I get smiles on faces. And that's also what ... and the whistle is loud! Better only outdoors spend ...
