Mark Posted October 3, 2013 Share Posted October 3, 2013 I wonder if anyone knows what this is? It is about 20cm in diameter, inserted into the ground, has a set of solar cells on the top, and "rattles" (I can hear and feel the rattle) for about 5 seconds every 30 seconds or so. There are several of them distributed around the orchard. For the life of me, I can't find any reference to this device. There are no other devices, machines, recording stations etc anywhere close. Any ideas? Thanks! Mark Link to comment Share on other sites More sharing options...
