I have a HDS 8 Gen 1. Will that box work for this head?
Yes, it will work with HDS generation 1 and 2. (I simply don't know the answer for Gen3.) What I don't recall clearly is the transducer. This is the box only, so you'd need a StructureScan transducer. Obviously an LSS2 transducer will work with it, but I don't recall what others may work with it. Some have said that an LSS1 transducer will, but I have NOT tried that myself. Be sure you get a power cord to go along with the box if you buy it.
