No idea about the Duet per se. But NASA kit is at the extreme end of the budget kit spectrum. As long as your expectations are low, you won't be disappointed.
Can't see much point of having it on a rib, it's more for the rag & string brigade.

It's cheap and cheerful. We fit a fair bit; and don't see a disproportionate amount of units failing so they aernt that bad but they are basic and cheap.
I don't see their transducers as suitable for rib use really.
You could get it working with a transom mount transducer from another manufacturer but strictly speaking NASA sonar is a different frequency to the kind of standard 50/200 nearly everyone else uses so it will always be a bit hit & miss.
In practice I have had to do exactly that for customers and it does work !!
