I just got 2 of theses guys that were supposed to be Ground Intrusion Detection devices used in Vietnam.
I would like to have more specs and history on them. The only thing I found so far was very general:
I quote:
"Scatterable sensors. These were small devices, mostly seismic.
They consisted of a seismic detector, a transmitter, and internal antenna, and a battery in a fiberglass or plastic case made to look like a broken branch, a big leaf, or other piece of forest litter. One type of sensor was designed to look like -- I am not kidding -- animal droppings. (Most of these things were Seismic Intrusion Detectors -- SIDs. These latter types were immediately named "TURDSID" by the guys using them.)
They were usually delivered by air, just dump a batch of them out along a trail, road, or in a suspected base camp area.
Because they were small, their batteries were small and transmitters were small. Battery life was not long -- a few days."
Thanks for your Help.
