I am selling four(4) KVH DSP-3000 gyroscopes. Perfect for making your own gyrostabilized gimbal. 3 of them are brand new in their sealed boxes, and the other was opened for a test fit(never opened, still sealed in anti-static bag/warranty seal still intact). Serial, 1000hZ, and asynchronous. Required mating harnesses are included. They were $5000 each at the time of purchase, and are $4299 each with 8 weeks of lead time as of this posting. Asking for $3500 a piece, otherwise make me a reasonable offer. Any questions/comments/offers, feel free to PM, email, or message me here.
