We make lots of them for WHOI, Hydroid, Benthos, and other Cape companies who are involved in this technology. A hotbed of this technology is Cape. We don't do the electronics just the mechanical aspects. I always wanted to have the use of one of those things. Basicly a perfect picture of whats down there in crystal clear color. I have looked at the Hummingbird thing, very interesting. Wonder if the imagery is as good as the test pictures they advertise. Not sure about the deployment of the sonar. Commercial ones are towed by boat or they go on their own with no strings attached, AUV.
