Has Anyone used NOBLETEC?

[CaptDana]

Faithful,
My new boat came with a 17" flt screen Big Bay and Big Bay marine PC made by(Nobletec). It is linked to a Raymarine GPS receiver and Sitex 48 Mile PC radar-- this is overlayed using the Nobletec Admiral software which includes chartplotter and charts- Here are my questions- From what I read, I can add the Nobletec PC based sounder-anyone have any experience with this- Otherwise- anyone have any options for me to add a good PC based sounder to my system? I would like to add a sounder to my onboard marine computer-but here in Michigan info on this system locally is nill. Just trying to get more educated on my options.
Thanks
