Smoking arrows.
  [vote for,

When bow hunting sometimes a shot will not make for a clean kill and the prey bolts, or the hunter may miss entirely wasting a perfectly reusable arrow.
A good hunter doesn't leave an animal to suffer and will track the prey for miles, even days if necessary.

I propose a fletching system which would release colored smoke for a time once released from a bow, so that either the prey or the buried arrow are easily found.


       How about arrows with RFID tags designed to take power from a hand-held radio beam, and chirp (either audibly or in RF or maybe even both)?

       I agree - radio-trackable arrows would make a lot more sense.   

       However, a [+] for combining two beautiful and under-used words in the title.

       While I agree that radio tracking would be more effective, that seems somewhat counter to the old-technology charm of bow hunting. Then again, a lot of the bows used for hunting aren't really old-technology either.

       I dunno, [scad]. I reckon electromagnetic waves were around before coloured smoke.

       The easiest solution would be to make the arrowhead from depleted uranium. Not only would this poison the wound but you could potentially triangulate with a geiger counter.

       a small flashing IR led might be useful here.

       Radio-trackable arrows are baked. As far as I know there aren't any off-the-shelf models available, but bowhunting catalogs sell DIY kits with RFID inserts that go inside the shaft. You can also get nocks with flashing LED beacons that activate on release.   

       I like this idea better. [+]

       // You can also get nocks with flashing LED beacons that activate on release// But IR leds would be visible on a cheap and nasty camera, and the deer would be oblivious, unless deer can see IR? I have no eye deer.

       Deer can't see IR. Their visible spectrum is surprisingly limited, but it's a trade-off for great night vision, incredible motion sensitivity, and a 280-degree field of view.
