[Milsurplus] bouy id

[Glenn Little WB4UIV]

Leigh and the group,

I suspect that this is an acoustic sonar buoy. The detachable weight on the 
bottom is probably used to rapidly take the transducer to the depth set by 
the length of cable connecting it to the buoy. There is probably a short 
length of silicon (?) runner with part of the transducer wire wound around 
it. This acts as a shock absorber. The weight ensures that the transducer 
deploys on impact with the water. Do you see any small transducers attached 
to the wire? There is probably an antenna on the top made of springy metal 
and a device near the base that will allow two knockout plugs to be 
release. This is to allow saltwater into the saltwater activated battery.

Is the diameter about 5 inches?


YMMV. The above comes from having used a similar buoy.
