I have four KVH DSP-3000 fiber optic gyroscopes. Serial, 1000HZ, asynchronous. Decided the DSP-5000's were more what I was looking for. Three of them are new and sealed in their original boxes, one has been opened for a test fit, and its still sealed in its anti-static bag. Can include pictures or answer any questions (hopefully).
Email or send a PM if interested.
